In the framework of the Lifewatch marine observatory nine fixed stations on the Belgian Part of the North Sea (BPNS) are visited on a monthly basis, and 17 fixed stations on a seasonal basis, using the RV Simon Stevin.

This dataset holds records of unique observations in the Belgian Part of the North Sea, which are not collected on a continous base ('loose observations') and do not fit into any of the other described LifeWatch Datasets.
