Particulate absorption (a P(λ)) including phytoplankton (a PHY(λ)) and non-algal particles (NAP) (a NAP(λ)) were measured in southeastern Bering Sea during a cruise in July 2008. This study analyzes the a P(λ) properties through in-situ and quasi analytical algorithm (QAA) derived ocean color satellite Medium Resolution Imaging spectrometer (MERIS) and Moderate resolution Imaging Spectroradiometer (MODIS) observations. We found that the a P(λ) and a PHY(λ) correlated well with chlorophyll-a and were lower as a function of chlorophyll-a as compared to low latitudes. The specific phytoplankton absorption (a* PHY(λ)) showed more variability in the blue as compared to the red part of the spectrum indicating pigment packaging and/or change in pigment composition. The remote sensing reflectance (R rs(λ)) showed significant variability in spectral shape and magnitude which was consistent with the variable total absorption minus pure water absorption (a T-W(λ)) spectra observed in the study area. Simple satellite retrieved R rs(λ) ratios were related to in-situ a PHY(λ) and a DG(λ) by applying an inverse power fit; R rs(490)/R rs(510) gave the best results for a PHY(443) and a DG(443) (R 2 - 0.80 and 0.75) respectively. The match-ups of in-situ and MERIS retrieved a PHY(λ) and NAP plus colored dissolved organic matter (a DG(λ)) using QAA after log-transformation showed reasonable agreement with R 2 of 0.71 and 0.61 and RMSE of 0.316 and 0.391 at 443 nm, respectively. Although the QAA derived a PHY(λ) and a DG(λ) from MERIS overestimated and underestimated, respectively the in-situ measurements at all wavelengths, the match-up analysis was encouraging.
