Seasearch Data 

 

We collect data during surveys, but what do we do with it?

What data do we have that YOU could use to make a positive change?

Data submission and QA

Seasearch diving and recording are carried out by volunteers. Many of them have a professional background in marine biology and conservation but many do not and are self-taught naturalists.

The data is submitted to us on Seasearch observation and survey recording forms and collated by regional coordinators. A breakdown of the number of forms submitted each year (from 2008 onwards) by each country or region is shown in the table.

We also have specialised recording forms for seafans and sea cave entrances (the latter in Scotland only).

Templates for forms can be downloaded from the Record page as PDFs to print out or complete digitally. When complete, please send them to us.

We have in place QA processes which are used to validate and verify Seasearch data so that they can be used with confidence. We have a commitment to ongoing data management whereby errors reported to us can be investigated, rectified as appropriate and the dataset updated.

Deciding where to go?

Use this map to identify areas that have been visited only once by Seasearch volunteers (red squares). Data from these sites can not yet be used to generate species trends. Adding a second visit to the site will enable that area to contribute to the models that predict species trends. Lets try and turn some of the red squares to blue!

Where has Seasearch been?

You can view annual summary maps for the positions of Seasearch surveys (each year from 2001 to 2020).

Data on the National Biodiversity Network

All of the Seasearch species data, and data from earlier Underwater/Marine Conservation Society surveys, are available to use and download from the National Biodiversity Network (NBN) Atlas. Data can be searched for by species or by grid square and you can choose to see just the Seasearch data or data from all of the providers.

The main Seasearch datasets (one for each country) contain over 750,000 species records. 

As well as the large Seasearch dataset, there are two smaller datasets. One contains additional records of pink sea fans, Eunicella verrucosa, and associated species. The other contains additional crawfish/spiny lobster, Palinurus elephas, records.

In addition to species data, habitat and biotope data are available in Marine Recorder Snapshot format on request.

Some species are considered to be "sensitive" so those records are shown as a 10km square and the exact positional information is only available on request with justification for use.

Data sharing and use

Seasearch data are distributed under a Creative Commons with Attribution (CC-BY) licence. We want our data to be as widely used as possible, but the source of the data should be properly credited. 

The data are made available in three ways:

- Survey reports - download from the Reports section.

- On the National Biodiversity Network Atlas.

- In Marine Recorder snapshot format – either on direct request to Seasearch or by downloading the JNCC public snapshot.

The data flow image  shows how Seasearch data fit into the UK and global "data landscape", being aggregated and shared into much larger data portals. The MEDIN portal is where all the survey metadata (data about data) is stored to provide discoverability.
