MSFD-Eutro: A new satellite-based demonstration service for assessment of Environmental Status Marieke Eleveld, Giorgio Santinelli, Dave de Koning, Cindy van de Vries 10 maart 2021

DIY with information from satellites © Skywalker. PL We map the chlorophyll pigment (CHL) indicative of phytoplankton. The satellite data are easily accessible through the innovative and interactive MSFD-Eutro demonstration service at http: //www. openearth. nl/msfd-eutro/ You can… analyse trends and capture maps and statistics. You can …evaluate the spatial impact of assessment levels interactively. We acknowledge CMEMS, ESA, EUMETSAT and Copernicus for satellite data. CMEMS for funding. 10 maart 2021 © Wikibob

Chlorophyll as indicator of standing stock phytoplankton Eutrophication status of the Greater North Sea (OSPAR Region II) as identified in the second application of the OSPAR Comprehensive Procedure for the period 2001– 2005 (OSPAR, 2010). 10 maart 2021 ICES boxes as an overlay over the annual geometric mean MERIS-derived chlorophyll concentration during the growing season Feb. 15 to November 15 of 2003 (Peters et al. , 2005; Vermaat et al. , 2008).

Chlorophyll as indicator of standing stock phytoplankton Eutrophication status of the Greater North Sea (OSPAR Region II) assessed under the third application of the Common Procedure (2006– 2014) in terms of problem areas, potential problem areas and non-problem areas (OSPAR, 2017). 10 maart 2021 MSFD-Eutro gives six-year mean and P 90 satellite-derived chlorophyll concentration during OSPAR growing season 1 Mar. – 31 Sept (for e. g. 2006– 2011. . 2009 -2014) and facilitates to interactively check the spatial impact of assessment levels (red arrows).

MSFD-Eutro and GES The objective of the MSFD is achievement of a GES in European waters by 2020. MSFD Descriptor 5 for GES states that humaninduced eutrophication is minimised, (especially adverse effects thereof, such as losses in biodiversity, ecosystem degradation, harmful algal blooms and oxygen deficiency in bottom waters. ) Differences also in surface concentrations can reflect local oceanographic conditions. Eutrophication assessments also involve winter nutrients levels. With optical remote sensing we cannot see nutrients that do not impact the water colour. Remote sening can provide optical and spatial information that can be used in the modelling. 10 maart 2021
