What is Estimating phytoplankton biomass in coastal waters of Alaska using airborne remote sensing about?

Empirical airborne remote-sensing relationships were examined to estimate chlorophyll a concentration in the first optical depth (chl FOD ) of coastal waters of Afgonak/Kodiak Islands during July -August 2002. Band-ratio and spectral-curvature models were tested using satellite remotesensing reflectance (R rs (k)) measurements. Additional shipboard and airborne R rs (k) data were also analysed to evaluate consistency of proposed chl FOD -R rs (k) relationships. Validation of chlorophyll algorithms was performed using data collected in the northern-part of the Gulf of Alaska and Bering Sea during 1996Sea during , 2002Sea during , and 2003 cruises. Likewise, oceanographic conditions during the surveys were typified to interpret variability of chl FOD fields. The SeaWiFS band-ratio algorithm OC2d was the most sensitive R rs combination (R rs (509)/R rs (553)) to detect chl FOD variability. Conversely, OC2a (R rs (412)/R rs (553)) had the lowest performance to derive chl FOD values. No valid statistical regressions were established for spectral -curvature relationships in the blue spectrum ( 5 mg m À 3 ) were preferentially located over shallow banks ( ̈50 m) and at the entrance of th
