title in English

LifeWatch observatory data: phytoplankton observations by FlowCam imaging in the Belgian Part of the North Sea

Description in English

Taxonomic disclaimer: The blooms of Rhizosolenia and Bellerochea were flagged due to their extreme nature, which can lead to biased density estimates during these bloom periods. These taxa, when blooming outside their typical seasons, can skew results, although abundances remain unaffected. Additionally, the sampling methods, such as net sampling and prefilters, inherently under-sample taxa near the 300µm threshold, further contributing to the need for flagging these extreme events. It especially relates to samples 2021 07 120 (Rhizosolenia, Long (chained) diatom) and 2022 08 130 (Bellerochea en Rhizosolenia)

Abstract in English

In the framework of the Lifewatch marine observatory a number of fixed stations in the Belgian Part of the North Sea (BPNS) are visited on a monthly or seasonal basis using RV Simon Stevin. A grid of nine stations covers the coastal zone and are sampled monthly. Eight additional stations, located further at sea, are sampled on a seasonal basis. Samples are taken using a 55µm mesh size Apstein net and fixed in Lugol's iodine solution. In the lab, the samples are processed using a VS-4 FlowCAM model at 4X magnification, size range imaged is 55-300µm. The identification of the image data is done with the use of a classifier and followed by a manual validation step. Since May 2017, this dataset provides micro- and phytoplankton observations, mainly covering diatoms, dinoflagellates and cilliates, for the Belgian Part of the North Sea (BPNS).
