2022-2024 FISP: Ecosystem Benefits of UK Oyster Aquaculture Sites Mumbles 2022 Sediment Sampling Survey - Version 1.1

data@mba.ac.uk (Data Team) — Tue, 22 Jul 2025 10:25:19 +0100

As part of the Fisheries Industry Science Partnerships (FISP) project 'Ecosystem Benefits of UK Oyster Aquaculture Sites' project partners Tethys Oysters Ltd. / Atlantic Edge Oysters Ltd., Envision Marine Ltd. and the University of Essex have collaborated in a research project to determine ecosystem benefits provided by oyster aquaculture by measuring biodiversity and denitrification activity at a variety of sites in England and Wales. Surveys were undertaken by ENVISION in 2023 to measure the biodiversity associated with three oyster farms and one naturalised rock oyster reef in comparison to control sites with similar environmental conditions, as well as ecosystem function (nitrification/denitrification activity) at these sites. Recognising the importance of conservation and restoration of native oyster populations, surveys were also carried out in 2022 and 2023 to measure oyster abundance and associated biodiversity at an historic native oyster site, commercially restocked with native oysters in 2021. Survey works included recording of underwater imagery, sediment sampling, oyster dredging and ecosystem function sampling. Underwater camera systems were used to record the diversity of biota around the oysters during submersion. Sediment samples were taken for measurement of diversity of macrofauna, particle size distribution and total organic carbon, and the ecosystem function testing involved sampling of sediment and swabs of oysters/hard surfaces to determine the abundance and activity of denitrifying/nitrifying microorganisms on oyster site substrates, through genomic analysis. The results of the denitrification and biodiversity services provided by oyster aquaculture were communicated to consumers, industry and decision makers to increase understanding and promote awareness of the ecosystem benefits provided by aquaculture.

Sea Watch Foundation Marine Megafauna Sightings:1930 to 1970 - Version 1.3

simone.evans@seawatchfoundation.org.uk (Simone Evans) — Tue, 13 May 2025 08:56:01 +0100

The Sea Watch Foundation has been collecting both effort-based and non-effort-based sightings data of marine mammals and other megafauna since the late 1960s. The main area of coverage is the waters around Britain and Ireland but with some surveys elsewhere. Data come from platforms ranging from small to large vessels either on dedicated survey or platforms of opportunity, and from coastal land sites. Data collected include environmental conditions, marine traffic, and seabird associations. Sighting records come from all types of marine user from marine mammal biologists to citizen scientists and members of the public. All sightings are checked, and species ID validated from still or video images and/or descriptions, except in those cases where persons are known, experienced, observers.

L4PHYTO_Phytoplankton taxonomic abundance time-series, Western Channel Observatory L4, 1992-2020 - Version 1.5

data@mba.ac.uk (Data Team) — Mon, 12 May 2025 15:52:11 +0100

The Station L4 phytoplankton time-series (Widdicombe et al 2010) contains taxa-specific and total functional group abundance (cells mL-1) and biomass (mgC m-3) data collected from the Western Channel Observatory's Station L4 monitoring site (50°15.0'N; 4°13.0'W), situated off the south-west coast of England, United Kingdom. Samples have been collected weekly (weather permitting) from the 10m depth since October 1992. Note the time of collection is estimated (local time) where CTD data are not available, and a gap in sampling occurred between October 1994-June 1995. Paired 200 mL water samples are collected using a 10 L Niskin bottle attached to a CTD and are fixed in acid Lugol's iodine (Throndsen, 1978) for enumerating all phytoplankton cells >2 µm and neutral formaldehyde for enumerating coccolithophores. Samples are analysed at Plymouth Marine Laboratory according to the Utermöhl counting technique (Utermöhl, 1958) and since 2016, these methods follow the British and European standard document "Water quality - Guidance standard for routine microscopic surveys of phytoplankton using inverted microscopy (Utermöhl technique)" (BS EN 15204:2006). Individual taxa are grouped into Diatoms, Dinoflagellates, Coccolithophores, Flagellates, Phaeocytis and Ciliates and these pooled data precede the individual taxa-specific data. Abundance of each taxa (cells mL-1) are calculated according to the number of individuals per unit volume of sub-sample analysed. Mean cell dimensions (µm) of each taxa have been estimated using digital measurements, calibrated against an ocular micrometer and converted to biovolume assuming appropriate geometric shapes (e.g. Olenina et al 2006). Cell biovolumes are converted to carbon (pgC cell-1) using the formulae of Menden-Deuer and Lessard (2000). Two analysts have generated the data since 1992 and in 2005 more ciliates were identified to species level hence the increase in the number of taxa. Please read the taxa-specific metadata file for information on individual biovolume and carbon values, identification consistency and data quality issues.

2015 SSE Renewables Beatrice Offshore Wind Farm pre-construction benthic grab survey - Version 1.1

data@mba.ac.uk (Data Team) — Tue, 12 Nov 2024 09:15:35 +0000

A pre-construction benthic characterisation survey was conducted by APEM Ltd at the proposed Beatrice Offshore Wind Farm (OWF) and Annex 1 Habitat Survey of the Offshore Transmission Works (OfTW) cable corridor (APEM ref 413984, client ref ED518) between the 22nd and the 27th June 2015. The aim of the survey was to collect grab samples that will provide baseline data on the benthic ecology and sediment composition within the OWF area. Additionally the survey was to utilise Drop Down Video (DDV) to determine the presence of potential cobble reef Annex 1 habitats (EC Habitats Directive) the OfTW cable export corridor and investigate sites of potential archaeological importance within both the OWF area and export route. Twelve grab stations were selected to provide representative coverage of the SS.SCS.ICS.MoeVen (Moerella spp. with venerid bivalves in infralittoral gravelly sand) biotope that was identified as being of high importance in the Beatrice OWF Environmental Statement and Supplemental Environmental Impact Statement and is representative of the ‘Tide-swept coarse sands with burrowing bivalves’ Priority Marine Feature. Ten of the stations were located within the OWF boundary, with two reference stations located to the north east of the OWF. All stations corresponded to locations that were sampled during the EIA baseline characterisation study undertaken in 2010 (CMACS, 2011). At each of the twelve locations three replicate samples were acquired using a 0.1m2 Hamon grab. Each replicate was then sub-sampled for both macrofauna and Particle Size Analysis (PSA).

1999 - 2010 Alien species of Bugula (Bryozoa) along the Atlantic coasts of Europe Surveys of Marinas and Harbours - Version 1.1

data@mba.ac.uk (Data Team) — Tue, 29 Oct 2024 08:56:59 +0000

Three apparently non-native species of Bugula occur in marinas and harbours in Atlantic Europe. The most common, B. neritina, was known from a few sites in southern Britain and northern France during the 20th century, following its discovery at Plymouth by 1911. During the 1950-60s it was abundant in a dock heated by power station effluent at Swansea, south Wales, where it flourished until the late 1960s, while water temperatures were 7-10°C above ambient. It disappeared after power generation ceased, when summer temperatures probably became insufficient to support breeding. Details of disappearances have not been recorded but B. neritina was not seen in Britain between c1970 and 1999. Since 2000, it has been recorded along the south coast of England, and subsequently in marinas in the southern North Sea, Ireland and southern Scotland, well to the north of its former range, as well as along the Atlantic coast from Spain to The Netherlands. It has also been introduced to outlying localities such as the Azores and Tristan da Cunha. We report that this rapidly spreading form has the same COI haplotype as B. neritina currently invasive elsewhere in the world. B. simplex has been reported less, with 1950s records from settlement panels in some Welsh docks. It has not been targeted in most recent marina surveys but has been observed in southwest England, Belgium and The Netherlands. There are almost no recent records of B. stolonifera, though it was probably introduced to a few British and Irish ports prior to the 1950s. Its current status in most of western Europe is unknown but it has been reported as expanding throughout most of the world during the last 60 years. Having poorly known distributions, B. simplex and B. stolonifera should be recorded during future monitoring of alien species in Atlantic Europe. Illustrations to aid identification are included for all three species.

2015 - 2018 Marine Biological Association of the United Kingdom (MBA) Western English Channel standard haul demersal fish survey data - Version 1.1

data@mba.ac.uk (Data Team) — Tue, 09 Jul 2024 11:07:48 +0100

Time series data of demersal fish populations in the Western English Channel sampled using a large otter trawl (15m headline) by the Marine Biological Association of the United Kingdom from 2015-2018. This data set contains vertebrate data only from 108 trawls. For each trawl, the entire catch was identified to species level. This dataset contains abundance, length, weight and disk width (if applicable) measurements. This dataset contains consistent sex data for elasmobranchs. Data of lower confidence levels has been excluded including that of invertebrates and sex data of non-elasmobranchs which can be requested via MBASepia@mba.ac.uk. These excluded data include high confidence cephalopod, scallop and large crab abundance as well as counts of other invertebrates including other crustaceans and echinoderms. Record Types (see SpeciesNotes in taxon form) describe the measurements that were carried out for the sample and/or individuals: Individuals - (Each individual caught has been weighed, measured and counted), Abundance / Weight - (All individuals landed have been weighed and counted as a whole, not individually), Sub-sample (Abundance) - (Measured total weight off all landed individuals, and from this estimated total abundance) & Sub-sample (Weight) - (Counted the total abundance of all landed individuals and from this estimated the total weight). The Sepia team database containing the MBA fisheries data automatically generates unknown weights to read as 1g, this means that it is near impossible to determine whether a weight is unknown or a genuine weight when reads as 1. Therefore any total biomass weights of 1g have been changed to 'unknown'. Individual specimen data has been retained as original vaues since these are more likely to have weights of 1g but should be treated as correct under the data user's discretion.

1988-2011 Stebbing et al. British records of American lobsters, Homarus americanus - Version 1.1

data@mba.ac.uk (Data Team) — Tue, 14 May 2024 12:22:38 +0100

American lobsters (Homarus americanus) are native to the east coast of North American and Canada, but have been imported live into Europe for several decades resulting in their escape into the wild. American lobsters have the potential to have a significant impact on the European lobster (Homarus gammarus) fisheries in Europe, but the status of American lobsters is not well understood, especially in Great Britain (GB) where reports have been sporadic. Reports were collated from across GB of American lobsters being caught in coastal waters. Between 1988 and 2011, 26 individuals have been positively identified using standard taxonomic techniques. American lobsters were found predominantly in waters off southern England, with no confirmed reports from Wales and a single report from Scotland. However, there are anecdotal reports of American lobsters being found in much greater numbers from around GB. The potential threat that American lobsters pose to fisheries in GB and the rest of Europe is discussed along with recommendations to better estimate the numbers of animals being released.

2009-2016 Loxton et al., Distribution of the invasive bryozoan Schizoporella japonica in Great Britain and Ireland and a review of its European distribution - Version 1.1

data@mba.ac.uk (Data Team) — Tue, 28 Nov 2023 10:08:09 +0000

The bryozoan Schizoporella japonica Ortmann (1890) was first recorded in European waters in 2010 and has since been reported from further locations in Great Britain (GB) and Norway. This dataset provides a new earliest European record for the species from 2009. The presence records of Schizoporella japonica at 28 sites in Europe are reported only, out of the 231 sites surveyed through rapid assesment surveys. This species is typically associated with human activity, including commercial and recreational vessels, aquaculture equipment, and both wave and tidal energy devices. It has also been observed in the natural environment, fouling rocks and boulders. The species has an extensive but widely discontinuous distribution in GB and Ireland. Although found frequently in marinas and harbours in Scotland, it inhabits only a few sites in England, Wales and Ireland, interspersed with wide gaps that are well documented as genuine absences. This appears to be a rare example of a southward-spreading invasion in GB and Ireland. The species has been reported from the Isle of Man and Norway but has not been found in France or Portugal. In the future we expect S. japonica to spread into suitable sections of the English, Welsh and Irish coasts, and further within Europe. The species’ capability for long-distance saltatory spread and potential for negative impact on native ecosystems and economic activity suggests that S. japonica should now be considered invasive in GB and Ireland. As such, it is recommended that biosecurity procedures alongside effective surveillance and monitoring should be prioritised for regions outside the species’ current distribution.

2014 Scottish Natural Heritage (SNH) site check survey of intertidal sediment flats of Loch Moidart, Lochaber - Version 1.0

data@mba.ac.uk (Data Team) — Thu, 24 Aug 2023 16:40:02 +0100

Site condition monitoring of the intertidal sediment flats of the Loch Moidart and Shiel Woods SAC was initiated in 2003. The work of the current 2014 study was to carry out a Site Check survey of the sediment flats to provide an assessment of the current condition of the intertidal sediment flat feature. The five relocatable transects established in 2003 were re-examined, which involved checking the presence and sequence of biotopes along the transects. A subsidiary aim of the survey work was to produce a biotope map of the sediment flats. This involved supplementing the site check data by walking over the area recording the nature of the substratum and conspicuous biota observed in the form of target notes at fixed positions.

2010-2013 Ryland et al. UK first Schizoporella japonica records - Version 1.0

data@mba.ac.uk (Data Team) — Thu, 27 Jul 2023 12:28:01 +0100

Schizoporella japonica Ortmann was described from Japan but was subsequently introduced on Pacific oysters to the Pacific coast of North America, where it is now well established. In this paper we record it for the first time in European waters. The initial discovery was in a marina at Holyhead, North Wales, in July 2010 but S. japonica has since been observed abundantly in the Orkney Islands (from May 2011) and, subsequently, at other localities in northern Scotland. Introduction seems most likely to have been on an ocean-going vessel. The British material is here fully described and illustrated with SEMs and colour photographs; some unusual characters are discussed. Unlike other recently introduced bryozoans, S. japonica is a cold-water species and its breeding season in Britain extends through the winter. Extensive confusion between this and other species of Schizoporella on the west coast of Canada and the USA led us to make thorough morphometric comparisons between the species concerned (Schizoporella unicornis (Johnston in Wood), Schizoporella errata (Waters) and Schizoporella pseudoerrata Soule, Soule and Chaney). Zooid size in cheilostomate bryozoans is variable and often an unreliable character for species separation but shape (and therefore ratios between variables,which are independent of size) are often valuable: S. japonica zooids have a much greater length:width ratio than the other species. Density of frontal pseudopores provides a useful discriminatory character. Schizoporella unicornis, repeatedly reported in error from the Pacific coast of North America, does not occur there; it is a European species. Full comparisons are made between S. japonica and S. unicornis for European identification and between S. japonica, S. errata and S. pseudoerrata (which are also illustrated) for North American localities.

2014 Heiser, S. et al Plymouth Sound Undaria pinnatifida Records - Version 2.1

data@mba.ac.uk (Data Team) — Mon, 08 Jul 2019 13:09:11 +0100

This dataset contains records from Heiser et al (2014) Assessing the extent of establishment of Undaria pinnatifida in Plymouth Sound Special Area of Conservation, UK Marine Biodiversity Records, page 1 of 8 doi:10.1017/S1755267214000608; Vol. 7; e93. The first UK record of Undaria pinnatifida was in the Hamble estuary (1994) and it was found off Plymouth in 2003. The authors assessed the distribution of U. pinnatifida and native kelps and their allies in Plymouth Sound (at 0 to +1 m relative to Chart Datum). Undaria pinnatifida was widespread along rocky shores, on other hard substrata and grew in the same areas as Saccharina latissima and Saccorhiza polyschides. Undaria pinnatifida was significantly more abundant on vertical substrata than on upward-facing hard substrata. It was almost as common as all of the other kelp species combined on vertical substrata but was outnumbered by native species on upward-facing substrata. Undaria pinnatifida has become the visually dominant macroalga in marinas and has spread to surrounding natural habitats in Plymouth Sound. The extent to which it will out-compete native kelps requires monitoring, especially in conservation areas.

2004 Southward et al. UK habitat and distribution of the warm-water barnacle Solidobalanus fallax (Crustacea: Cirripedia) records - Version 1.5

data@mba.ac.uk (Data Team) — Mon, 08 Jul 2019 12:57:31 +0100

New records are given of the occurrence of the warm-water barnacle Solidobalanus fallax in Britain and Europe. This barnacle is not found on rocks or stones, but settles on biological substrata, including algae, cnidarians, bivalves, gastropods and crustaceans. It also settles on plastic bags and nets, plastic-coated objects such as crab and lobster pots and octopus pots made of ceramic or plastic.With one exception the species was unrecorded in Europe before 1980; it may have increased in abundance during recent years as a result of rising temperatures.The cyprid larvae, which can metamorphose on plastic Petri dishes, appear to be adapted to seek out ‘low energy’ surfaces. One of the habitats colonized by S. fallax is the sea-fan Eunicella verrucosa, where it seems to have increased in recent years, possibly to the detriment of the cnidarian host. Solidobalanus fallax has the potential to be a serious pest of fish-farming structures to the south of Britain.

1960-1970 Barnes, RSK and Coughlan, J Blackwater Estuary Bottom Fauna Dredge Survey - Version 2.2

data@mba.ac.uk (Data Team) — Mon, 29 Jul 2019 11:50:32 +0100

A number of additions and corrections are made to the Blackwater Estuary fauna list. Distribution patterns revealed by a survey of the benthic fauna of the Blackwater Estuary in May 1970 are described, and changes in the frequency of occurrence of a number of species between 1960 and 1970 are discussed. It is concluded that the fauna of the region has, to a large extent, recovered from the severe winters of 1961-62 and 1962-63.

A monthly sampling programme was carried out in 1975 of an intertidal population of Ficopomatus enigmaticus at Greenhithe, Kent. Greenhithe is on the south side of the Thames Estuary, and the study site (O.S. TQ 59367548), beneath a disused jetty belonging to Empire Paper Mills, is immediately opposite the large power station at West Thurrock, and 33-8 km below London Bridge, the normal limit for sea water ingression.

Sea Mammal Research Unit (SMRU) UK aerial surveys of harbour seals (Phoca vitulina) and grey seals (Halichoerus grypus) during the summer harbour seal moult 2016-2019 - Version 1.2

data@mba.ac.uk (Data Team) — Tue, 16 May 2023 14:59:31 +0100

The Sea Mammal Research Unit (SMRU) conducts an ongoing programme of aerial surveys along the English and Scottish coastlines during the harbour seal (Phoca vitulina) summer moult. These surveys are funded by the Natural Environment Research Council (NERC National Capability Funding, Grant Numbers SMRU10001 and NE/R015007/1), NatureScot, formerly Scottish Natural Heritage (SNH), and Natural England.

To monitor harbour seal numbers, individuals onshore are counted in August, during their annual moult season, when animals generally spend more time hauled out. Such moult season counts tend to be slightly higher and more consistent than at other times of year. Grey seals (Halichoerus grypus) are also counted during these summer surveys, but their distribution can change more throughout the year because they congregate in breeding colonies during the autumn. These aerial surveys are conducted within 2 hours of low water using either a helicopter or fixed-wing aircraft. No surveying is carried out during periods with prolonged rain or heavy showers.

The helicopter surveys began in 1988 and cover a different area each year. A full round of Scotland usually takes 3-5 years to complete. This dataset covers the 2016-2019 round of helicopter surveys that used multi-sensor (infrared, high-resolution DSLR, and video) gimbal-led imaging.

Parts of the Moray Firth as well as the Firth of Tay and Eden Estuary Special Area of Conservation (SAC) are surveyed annually. Almost all the seals here haul out on sandbanks, which makes them much easier to spot. For that reason, less expensive fixed-wing aircraft and hand-held photography can be used.

The same applies to the main harbour seal areas in England. Each year, SMRU performs fixed-wing surveys of the coastlines of Lincolnshire and Norfolk between Donna Nook and Scroby Sands. Less frequently, SMRU also surveys the Thames Estuary from Felixstowe to Goodwin Sands (fixed wing 2018 and 2019), the East Coast from around Coquet Island to Flamborough Head (fixed-wing 2016), and the Berwickshire and North Northumberland Coast SAC (helicopter 2018).

The presence/absence and counts of hauled-out individuals from each of the years from 2016 to 2019 have been aggregated using the cells of a 5 km x 5 km UTM zone 30N (EPSG:32630) grid. Mean values are given for cells surveyed more than once in a single season. No value is reported if only part of the intertidal zone within a given cell was surveyed during a given year.

The reports produced by SMRU for NERC’s Special Committee on Seals (SCOS), in particular Briefing Papers 17/03, 18/04, 19/03, and 20/03 in the 2017-2020 reports, contain additional information on these surveys and the data gathered. These are available from SMRU’s website: http://www.smru.st-andrews.ac.uk/scos/scos-reports/

Further details of the Scottish surveys over this period and the data they collected can also be found in this report: NatureScot Research Report 1256 - Aerial surveys of seals in Scotland during the harbour seal moult, 2016-2019 https://www.nature.scot/doc/naturescot-research-report-1256-aerial-surveys-seals-scotland-during-harbour-seal-moult-2016-2019

Irish Benthos monitoring as part of the Water framework directive since 2012 - Version 2.0

data@mba.ac.uk (Data Team) — Wed, 06 Oct 2021 14:15:57 +0100

A requirement of the Water Framework Directive is that benthic macro-invertebrates must be sampled from coastal and transitional waters at least twice within a river basin cycle (6 years) in order to classify these waterbodies. Numerous samples will be taken from sites in matched habitats throughout the water body. Sampling and analysis is carried out according to established protocols. The Directive requires the sampling of nominated coastal and transitional waters for benthic macro-invertebrates. This includes the field sampling, processing and analysis of samples. In addition, grab samples have been taken on vessels of opportunity and are considered suitable to fulfill obligations under the WFD. For each grab sample collected this dataset contains: - lists and abundance of benthic species >1mm, -sediment particle size analysis (PSA), -Folk (1954) sediment classification, and an estimate of organic matter (LOI).

Phytoplankton abundance data from the Gibraltar coastline 2009-2019 - Version 1.3

data@mba.ac.uk (Data Team) — Tue, 07 Sep 2021 10:53:51 +0100

Full community phytoplankton analysis results, expressed as cells per litre, from samples collected from the Gibraltar coastline between 2009 to 2019. The data were derived from water samples collected at a 2m depth using a Niskin sampler on an quarterly basis at four sites by HM Government of Gibraltar. Site positions are included in the dataset, and are accurate to +/- 30m. Samples were preserved with acidified Lugol's Iodine and sent immediately after collection. Once received by Cefas, samples were analysed using the Utermohl method detailed in the UKNRL SOP for phytoplankton (https://www.afbini.gov.uk/publications/uk-nrl-phytoplankton-enumeration-sop), using high-power inverted microscopes, as soon as possible after receipt in order to reduce deterioration of the cells. Identification was to genera or species level where possible, according to light microscopy limitations, and was otherwise to taxonomic or morphological groupings. Size categories are available for some species and for morphological/taxonomic groups. Between 2009 and 2015, the counting methods consisted of either Whole Baseplate or Fields of View. From late 2015, the counting method of Transects was introduced, and used alongside Whole Base and Fields of View.

National Monitoring Programme for Phytoplankton Species occurrence in Aquaculture Production Areas - Version 1.5

data@mba.ac.uk (Data Team) — Thu, 27 May 2021 12:31:48 +0100

The Phytoplankton National Monitoring Programme for the identification and enumeration of phytoplanktonic species is an important measurement in the detection of those species which may form a Harmful Algal Bloom event. Where favourable environmental conditions occur, some species may form 'blooms' where high cell densities may cause water discolouration, foaming, mass mortalities of fish, shellfish, invertebrate and benthic organisms through oxygen depletion or produce biotoxins which can accumulate in species of filter feeding bi-valve molluscs, which can cause a variety of human illnesses if consumed when placed on the market for human consumption. more Since the 1980's, the Marine Institute have been operating a monitoring programme for the detection of these phytoplanktonic species via microscopy (method accredited to ISO 17025 standards) and have been publishing results of this analysis on a daily basis to competent authorities (The Food Safety Authority of Ireland& Sea-Fisheries Protection Authority) and industry. Samples are currently taken on a weekly basis from Classified Production shellfish aquaculture areas all around the Irish Coastline (up to approx. 100 production areas from Co. Louth - Co. Donegal), with a smaller number of samples taken from finfish aquaculture production sites. Samples are submitted to MI laboratories in Bantry & Galway for analysis where sample details, analysis and results are inputted, stored in, and generated from the Harmful Algal Blooms database (HABs - SQL Server database developed in-house), which has been in operation since 2002. These results are published from HABs and are publicly available through MI website; webapps.marine.ie/habs and are tabulated and graphed to show the occurrence, trends and patterns of HAB events, where all results from 2002 - current date can be downloaded per production area. This monitoring programme is in accordance with the relevant EU Legislation (627/2019), where the results feed into the NMP for marine biotoxins in shellfish.

Groundfish Survey Invertebrate Data - Version 1.4

data@mba.ac.uk (Data Team) — Thu, 27 May 2021 12:27:24 +0100

The Irish Groundfish Surveys is part of an annual International Bottom Trawl Survey (IBTS) programme co-ordinated by the International Council for the Exploration of the Sea (ICES). The survey is carried out over 47 days between October-December each year by the Marine Institute and collects demersal trawl and ancillary data in Irish waters to produce relative abundance indices for fisheries management in the Northwest Atlantic Shelf waters. more In addition to the commercially exploited fish, elasmobranch, cephalopod and crustacean species, and an amount of macroinvertebrate species are also caught. These are sampled in a similar way to the groundfish, identified by species (or higher taxa where not practical to ID at sea), and total weight as well as counts are recorded where possible. An internal review of this data was undertaken in 2019 to check for spatial and temporal consistency in abundance and taxonomy with the standardised data set being made available here.

SmartBuoy Marine Observational Network - UK Waters Phytoplankton Data 2001-2017 - Version 1.3

data@mba.ac.uk (Data Team) — Wed, 24 Feb 2021 15:38:45 +0000

This dataset consists of analysed phytoplankton data from the years 2001-2017 inclusive collected in UK waters from the SmartBuoy moorings at Celtic Deep, Dowsing, Gabbard/West Gabbard/WestGabbard2, Warp and Liverpool Bay using WMS and EDU automated water samplers. SmartBuoys consist of a 4 meter tall stainless steel frame with a fibreglass toroid for buoyancy. Instruments are attached at a nominal 1 meter depth to the frame. The water samplers collect into pre-spiked bags containing acidified Lugols Iodine on a pre-determined cycle over the course of a deployment. Following recovery these samples were analysed for a full community of phytoplankton species using the Utermohl method on high-power inverted microscopes. Phytoplankton cell counts are abundance values reported in Cells per Litre.

Marine Recorder JNCC Public Offshore Snapshot 2020_1 – habitat data trial - Version 4.6

Data comprises multi-thematic benthic surveys in the offshore, including both taxa occurrence and abundance alongside physical and biotope recordings. This dataset is being used as a pilot study into submitting fully classified biotope data into OBIS alongside associated taxonomic occurrences under the EU EMODnet initiative.

Macrobenthos Data from Shoreham, the Tyne and the Thames Estuaries, UK, 2000 to 2006 - Version 1.4

data@mba.ac.uk (Data Team) — Fri, 26 Jun 2020 13:13:46 +0100

These data describe counts of macrobenthic infauna (with associated station metadata) taken from sediment samples collected at sites in the Tyne, Thames and Shoreham, UK from 2000 to 2006. For selected samples, wet biomass data is also included per taxon. The samples from the Shoreham site were collected across an aggregate extraction area over 4 years with the aim to test several habitat mapping techniques by documenting the presence of different faunal levels across the area. The samples collected at the Tyne and Thames were initiated at former sewage sludge disposal sites. Cefas conducted annual sampling in these areas during and post cessation of sewage disposal after January 1999 to monitor the benthic macrofauna community. To obtain the macrofauna, sediment samples were collected using a sediment samples collected using a Day Grab (Van Veen, 0.1m2) or a Hamon grab (either 0.1m2 or 0.25m2), depending on the area and nature of the sediments. Samples were then immediately sieved on board with running seawater over a 0.5mm and/or 1mm mesh sieve to remove the sediment. After sieving, the samples were preserved in 5% buffered formaldehyde. On return to the laboratory, the samples were washed to remove the formaldehyde and the macrofauna extracted using light microscopy and preserved in 70% Industrial Methylated Spirit. Animals were identified to the lowest taxonomic level possible and each taxon enumerated to generate the abundance information. The in some samples, the same animals were then weighed after blotting (wet weight) to the nearest 0.0001g to obtain biomass information.

Young Fish Survey Data 1981 to 2010 - Version 1.4

data@mba.ac.uk (Data Team) — Wed, 18 Mar 2020 13:56:07 +0000

Total numbers of individual fish identified during the Cefas Young Fish Survey (YFS) which ran from 1981 to 2010. The survey deployed a light 2-meter beam trawl to survey inshore locations for small / young fish around the British Isles, predominantly along the south and east coasts. Total numbers of fish (identified to species or if not to the highest taxonomic level) were recorded at each station, and were measured in the majority of cases. The surveys were primarily undertaken to evaluate the abundance of juvenile sole and plaice, as well as providing further information on the abundance of other species of fish. The YFS formed part of the International Young Fish Survey, coordinated by ICES. The survey used commercial inshore vessels to sample with a light 2-meter beam trawl deployed at fixed (prime) stations, towed for a duration of 10-minues, with varying coverage of the British Isles over the time-series period. From 2000 onwards actual shot and haul positions were recorded, whereas prior to this a single generic position was given for a specific prime station. Fish species were nearly always measured, and on the very few occasions that they were not they were counted. These data are currently undergoing quality assurance. Species-specific records for gobies are known to contain taxonomic errors, and analyses should be undertaken on data aggregated to the level of family (Gobiidae). Data for sand smelt Atherina spp. and smelt Osmerus eperlanus may also be confounded, and data for these taxa should be interpreted with particular care.

data@mba.ac.uk (Data Team) — Wed, 20 Jun 2018 10:53:59 +0100

Three phytoplankton species blooms which have been reported harmful to fisheries in UK waters are discussed: (1) The armoured dinoflagellate Gonyaulax tamarensis has caused harmful levels to humans of paralytic shellfish poison in most years since 1968 in shellfish from sites on the British east coast between 54.5°N and 56.7°N. The months of maximum toxicity are May and June. (2) Red tides of the naked dinoflagellate Gyrodinium aureolum have caused mortalities of wild marine animals in south-west England in 1978 and in North Wales in 1971, and killed farmed salmon in the west of Scotland in 1980. These red tides occurred between August and October. The dinoflagellate occurs all along the west coast of Britain and is often abundant at fronts. (3) Blooms of flagellate X, possibly a species of Olisthodiscus or Chattonella, have killed farmed fish in sea-lochs on the west coast of Scotland in 1979 and 1982.
