The use of ocean colour remote sensing data has increased dramatically over the last ten years, particularly for coastal waters where impacts between the marine environment and human activities may be particularly intense. Many of these coastal waters will be turbid because of high concentrations of suspended particulate matter caused by a variety of processes including high biomass algal blooms, sediment resuspension by wind/tide, river plumes, etc. Within these lectures on “Ocean Colour...

1.What are harmful algal blooms (HABs)? Contrast of HABs to functional groups What must be known to detect HABs Environment Simple physiology and ecology Ecological conditions “Operational” vs research considerations Work exercise: A strategy to respond to reports of a HAB 2.Methods Chlorophyll Change detection Analytical algorithms Spectral shape (MCI, FLH, CI) Other algorithms (brightness,...

Ocean colour remote sensing has often been used to study polar seas, especially in Antarctica where the optical properties of the upper ocean are not as complex as they are in the Arctic (Comiso et al., 1990, Comiso et al., 1993, Sullivan et al., 1993, Arrigo et al., 1998, Stramski et al., 1999, Arrigo et al., 2008b). It was shown based on OC data that primary production in Antarctic waters has changed little over the last 14 years (Arrigo et al., 2008b). In contrast, the few studies that...

This class will focus on retrieving information from the quantum yield of Sun‐induced fluorescence using remote sensing. After reviewing the basic theory behind fluorescence emission in the cell and within the water column, we will examine the recent algorithms proposed to retrieve the quantum yield in open ocean waters. Finally, we will examine different proposed interpretations of the variability in the quantum in the ocean that were developed both from in situ measurements and from remote...
