Cryptophytes: a keystone algal group in the rapidly changing Antarctic Peninsula marine environments - data availability

This dataset contains the results of relative and absolute contributions of cryptophytes derived from the HPLC/CHEMTAX analysis. The data were collected during the late summer (February) between 2008-2018 along the Northern Antarctic Peninsula. The index of photoprotective carotenoid pigments to chlorophyll-a (PPC: Chl-a) used in the study is also presented.
