The exceptional surface turbidity of the North-West European shelf seas during the stormy 2013-2014 winter: consequences for the initiation of the phytoplankton blooms? 5
Gohin, Francis; Bryere, Philippe; Griffiths, Joshua.
A succession of storms during the winter 2013-2014 enhanced the resuspension of sediments in the surface waters of the North-West European shelf seas. The effects of waves on satellite-derived non-algal SPM (Suspended Particulate Matters) are discussed for the January 2008-March 2014 period. A simple statistical model relating locally SPM to tidal intensity and waves help us analyse the main characteristics of the winter 2013-2014. The exceptional run of storms observed in this stormy and rainy winter has resulted in the highest SPM concentration in the Celtic Sea and the Bay of Biscay ever observed by remote-sensing during the 1998-2014 period. Despite the lower clarity of the surface waters over a large part of the continental shelf during the first days...

ROSACE: A Proposed European Design for the Copernicus Ocean Colour System Vicarious Calibration Infrastructure 5
Antoine, David; Vellucci, Vincenzo; Banks, Andrew C.; Bardey, Philippe; Bretagnon, Marine; Bruniquel, Véronique; Deru, Alexis; Hembise Fanton D’andon, Odile; Lerebourg, Christophe; Mangin, Antoine; Crozel, Didier; Victori, Stéphane; Kalampokis, Alkiviadis; Karageorgis, Aristomenis P.; Petihakis, George; Psarra, Stella; Golbol, Melek; Leymarie, Edouard; Bialek, Agnieszka; Fox, Nigel; Hunt, Samuel; Kuusk, Joel; Laizans, Kaspars; Kanakidou, Maria.
The European Copernicus programme ensures long-term delivery of high-quality, global satellite ocean colour radiometry (OCR) observations from its Sentinel-3 (S3) satellite series carrying the ocean and land colour instrument (OLCI). In particular, the S3/OLCI provides marine water leaving reflectance and derived products to the Copernicus marine environment monitoring service, CMEMS, for which data quality is of paramount importance. This is why OCR system vicarious calibration (OC-SVC), which allows uncertainties of these products to stay within required specifications, is crucial. The European organisation for the exploitation of meteorological satellites (EUMETSAT) operates the S3/OLCI marine ground segment, and envisions having an SVC infrastructure...
