The ICES workshop on the production of swept area estimates for all hauls in DATRAS for biodiversity assessments will meet online 31 May–4 June 2021

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​WKSAE-DATRAS will harmonize the procedures to develop swept-area estimates to support biodiversity assessments using the ICES online database of trawl surveys (DATRAS).

DATRAS stores more than 45 years of data from bottom trawl fish surveys coordinated by ICES expert groups. Data from DATRAS are typically used for stock assessments but it can also be used to monitor and assess the status of fish communities and support the implementation of ecosystem-based management​.

Building on previous initiatives (ICES 2019), WKSAE-DATRAS will agree on time-series, quality check methodologies, and approaches to reduce missing data and calculate swept-area indices as input into OSPAR biodiversity common indicators for fish and food webs.

This workshop is part of the formal ICES advisory process in response to a request from OSPAR. As such, the workshop report will be peer-reviewed, after which an advice drafting group will be convened to draft advice for approval by ICES Advisory Committee (ACOM).

Workshop participants have a broad range of expertise and represent all ICES regions in order to ensure the wide applicability and use of the index. This includes ecologists, gear specialists, and survey and assessment group experts.
