Abstract:

The PIP25 indexes calculated by IP25 and phytoplankton biomarkers (Brassicasterol, Dinosterol, HBI-III) in the East Siberian Sea. To better understand the riverine influence, we compared the data set with and without samples that influenced by riverine input. In this dataset, the estuarine samples (surface salinity < 25) are removed. The calculation methods based on Mueller et al., 2015.
