Abstract SeaWiFS data (2001-2002) of Lake Baikal (Siberia, RU) has been investigated to support multi-disciplinary limnological investigation within the frame of the paleoclimate project CONTINENT. Using adapted SeaDAS processing for Lake Baikal, the OC2 chlorophyll algorithm performed adequately for Case 1 surface waters. On the other hand, for the case of high organic terrigenous input (Case 2 waters), there occurs a distinct switch in the spectral peak position and a chlorophyll overestimation. SPM is quantified by the regression of the SeaDAS attenuation coefficient, and field data. Applying these methods, the resulting chlorophyll and terrigenous input maps provide information as how to interrelate the findings from sediment trap and field data with the autochthonous and allochthonous material at the CONTINENT coring sites.

Scaling of coastal phytoplankton features by optical remote sensors: comparison with a regional ecosystem model
Different scales of hydrological and biological patterns of the Bay of Biscay are assessed using spaceborne and airborne optical remote sensing data, field measurements and a 3-dimensional biophysical model. If field measurements provide accurate values on the vertical dimension, ocean colour data offer frequent observations of surface biological patterns at various scales of major importance f...
متن کاملFrom silk to satellite: half a century of ocean colour anomalies in the Northeast Atlantic.
Changes in phytoplankton dynamics influence marine biogeochemical cycles, climate processes, and food webs, with substantial social and economic consequences. Large-scale estimation of phytoplankton biomass was possible via ocean colour measurements from two remote sensing satellites - the Coastal Zone Colour Scanner (CZCS, 1979-1986) and the Sea-viewing Wide Field-of-view Sensor (SeaWiFS, 1998...

A new generation of ocean colour satellites is now operational, with frequent observation of the global ocean. This paper reviews the potential to estimate marine primary production from satellite images. The procedures involved in retrieving estimates of phytoplankton biomass, as pigment concentrations, are discussed. Algorithms are applied to SeaWiFS ocean colour data to indicate seasonal var...
متن کاملSpatial differences in dissolved silicon utilization in Lake Baikal, Siberia: Examining the impact of high diatom biomass events and eutrophication
Recent research has highlighted how Lake Baikal, Siberia, has responded to the direct and indirect effects of climate change (e.g., ice-cover duration), nutrient loading, and pollution, manifesting as changes in phytoplankton/zooplankton populations, community structure, and seasonal succession. Here, we combine and compare analyses of chlorophyll a (an estimate of total algal biomass), caroten...
متن کاملRemote Sensing of Phytoplankton Groups in Case 1 Waters from Global Seawifs Imagery
Ocean color sensors enable a quasi-permanent monitoring of the chlorophyll a concentration, Chl a, in surface waters. This ubiquitous photosynthetic pigment cannot, however, be used to distinguish between phytoplankton species. Distinguishing phytoplankton groups from space is nevertheless necessary to better study some biochemical processes such as carbon fixation at the global scale, and is t...
