Chlorophyll- a in Antarctic landfast sea ice: a first synthesis of historical ice core data
Historical sea ice core chlorophyll‐ a (Chl a ) data are used to describe the seasonal, regional, and vertical distribution of ice algal biomass in Antarctic landfast sea ice. The analyses are based on the Antarctic Fast Ice Algae Chlorophyll‐ a data set, a compilation of currently available sea ice...

Historical sea ice core chlorophyll‐ a (Chl a ) data are used to describe the seasonal, regional, and vertical distribution of ice algal biomass in Antarctic landfast sea ice. The analyses are based on the Antarctic Fast Ice Algae Chlorophyll‐ a data set, a compilation of currently available sea ice Chl a data from landfast sea ice cores collected at circum‐Antarctic nearshore locations between 1970 and 2015. Ice cores were typically sampled from thermodynamically grown first‐year ice and have thin snow depths (mean=0.0520.097m). The data set comprises 888 ice cores, including 404 full vertical profile cores. Integrated ice algal Chl a biomass (range: <0.1219.9mg/m 2 , median=4.4mg/m 2 , interquartile range=9.9mg/m 2 ) peaks in late spring and shows elevated levels in autumn. The seasonal Chl a development is consistent with the current understanding of physical drivers of ice algal biomass, including the seasonal cycle of irradiance and surface temperatures driving landfast sea ice growth and melt.
