Global Distribution of Non-algal Particles From Ocean Color Data and Implications for Phytoplankton Biomass Detection
In the last few decades, phytoplankton biomass has been commonly studied from space. However, satellite analysis of non-algal particles (NAPs), including heterotrophic bacteria and viruses, is relatively recent. In this work, we estimate the backscattering coefficient associated with the NAP fractio...
