What types of data do you archive?

DASSH specializes in marine benthic survey data and/or information, for example species or habitat survey data, species lists, habitat or biotope lists, species or habitat/biotope distribution maps, figures, images, video clips and other relevant information (written or otherwise). DASSH is therefore, particularly interested in data, images or video. Data and image sources are likely to include the following.

What is Metadata?

Metadata is data about data. As a minimum, metadata describes who collected the data, where it was collected, when it was collected, what the dataset(s) describes, how the dataset was collected, and a contact person/organization or data provider from which a copy of the data can be obtained. Metadata standards ensure metadata is collected in a standardised way which allows it to be shared or combined to form a national information resource and help to answer management questions both nationally and internationally.

How do I submit data to DASSH?

Simply read though our 'Submit data' section for details. If you have any doubts simply email us (dassh.enquiries@mba.ac.uk).

Do I give away my intellectual property rights?

Contributing data/images to DASSH does not infringe or compromise your intellectual property rights! Intellectual property rights always remains with the Data provider and is protected by the DASSH Terms and Conditions.

Do you archive all marine environmental data?

That would be a massive task, so no! Fortunately there is a network of marine Data Archives Centres (mDACs) in the UK. Have a look at the list of mDACs in the links section. If you are still in doubt about where to submit your data contact DASSH and we will point you in the right direction (dassh.enquiries@mba.ac.uk).

When I try to view the a distribution map on the SEABED mapper I get an error.

Check to see that you have the required software installed. The SEABED mapper requires the Adobe SVG Viewer. It is free open source software and can be downloaded from the Adobe Web site. If you still experience errors contact us (dassh.enquiries@mba.ac.uk).

What do you mean by data?

Data is a catch all term by which we mean material, data or information, which includes species or habitat survey data, species lists, habitat or biotope lists, species or habitat/biotope distribution maps, figures, images, video clips and other relevant information (written or otherwise). Please note that images (slides, stills) and video or film can be important forms of data in their own right.

To be useful the data should comply with the four 'W's of biological recording, that is include, who, where, when, and of course what. 'Where' should include a geospatial reference, which is complicated way of saying a location or place, preferably with latitudinal and longitudinal coordinates, or as an absolute minimum a place name.

How do I interpret data?

There is no easy answer to this question. Benthic survey data varies considerably and its application or interpretation depends on how the data was collected and why. Users should consider the following points when interpreting data.

At the end of the day, the user is responsible for the interpretation and application of the data.Please refer to section two of our Terms & Conditions and look at clauses 2.1 and 2.5 in particular.

If you have any queries concerning the interpretation of data available through DASSH, please contact us dassh.enquiries@mba.ac.uk.
