Title

Specific phytoplankton absorption variability and implication for chlorophyll a retrieval in Belgian waters (Southern North Sea)

Abstract

Chlorophyll a retrieval from satellite is based on algorithms that convert the phytoplankton absorption into chlorophyll a by means of the specific- phytoplankton absorption. This factor has been found to be highly variable, spatially and seasonally. The variability of the chlorophyll a-specific phytoplankton absorption in Belgian waters (Southern North Sea) was investigated to determine how it is affecting the chlorophyll a retrieval from satellite information. The Southern Bight of the North Sea is a very dynamic area influenced by river discharges and characterised by highly variable chlorophyll, suspended matter and coloured dissolved organic matter absorption. The impact of using a mean value of specific-phytoplankton absorption as usually done instead of the real one in chlorophyll a retrieval was estimated and found to be significant (underestimation up to 70% at 665 nm).
