The Third CEARAC Experts Meeting on Eutrophication Assessment in the NOWPAP Region was held online on February 25, 2022.
Objectives:
– Review the progress of on-going CEARAC activities on eutrophication assessment
– Discuss the results of data evaluation
– Collect opinions and advice on improvements of the multi-sensor, long-term consistent satellite-derived chlorophyll time-series applied in eutrophication screening
Participants:
– Nominated experts from the NOWPAP member states on improvement of the NOWPAP Eutrophication Assessment Tool (NEAT) for assessment and monitoring of eutrophication using satellite chlorophyll-a
– NOWPAP RCU Representative
Main results:
– The meeting particimpants emphasised the importance of the continuation of in-situ data collection activity to help improving satellite product algorithms in coastal regions. The expert from Japan stressed on the need to more closely look at the submitted data and find patterns/trends that will help in algorithm update.
– The meeting agreed on the continuation of eutrophication assessment using the dataset that is being generated currently using three sensors (SeaWiFS, MERIS, and MODIS-Aqua) and applying the YOC (Yellow Sea Large Marine Ecosystem Ocean Color Project) algorithm. It was also agreed that CEARAC should simultaneously continue evaluating the consistency of satellite derived CHL products between different sensors to help in defining the best way to merge these datasets to make a single, long-term consistent dataset.
