The dataset was corrected in 11 September 2017 regarding Sound-Arkona and Kattegat-Great belt border. This dataset was updated in September 2017 following the update of http://www.helcom.fi/Documents/Action%20areas/Monitoring%20and%20assessment/Monitoring%20and%20assessment%20strategy/Monitoring%20and%20assessment%20strategy.pdf as agreed in https://portal.helcom.fi/meetings/STATE - CONSERVATION 6-2017-412/MeetingDocuments/Outcome of State and Conservation 6-2017.pdf. Islands under 1 ha have been removed from the dataset and polygon shape have been simplified with ArcGIS bend simplify tool with 100m maximum allowable offset in September 2017. Earlier version of the dataset was corrected in September 2013 by modifying assessment unit "Northern Baltic Proper Estonian coastal waters". The dataset was updated again in 2022 with changes collected for HELCOM assessment units to be applied in HOLAS III, presented on State and Conservation 15-2021, document 3J-94: https://portal.helcom.fi/meetings/STATE%20-%20CONSERVATION%2015-2021-843/MeetingDocuments/3J-94-Rev.2%20Summary%20of%20HELCOM%20assessment%20unit%20changes%20for%20HOLAS%20III.pdf In august 2022 the dataset was updated to incorporate changes on the Danish coast, resulting in changes in the areas of Kiel Bay and the Great Belt.
