description |
International audience 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 land fast sea ice. The analyses are based on the AntarcticFast Ice Algae Chlorophyll-a data set, a compilation of currently available sea ice Chla data from land fast 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 = 0.052 ± 0.097 m). The data set comprises 888 ice cores, including 404 full vertical profile cores. Integrated ice algal Chla bio mass(range:<0.1–219.9 mg/m 2 , median = 4.4 mg/m 2 , interquartile range = 9.9 mg/m 2 ) peaks in late spring and shows elevated levels in autumn. The seasonal Chla 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. Landfast ice regions with reported platelet ice formation show maximum ice algal biomass. Ice algal communities in the lowermost third of the ice cores dominate integrated Chla concentrations during most of the year, but internal and surface communities are important, particularly in winter. Through comparison of biomass estimates based on different sea ice sampling strategies, that is, analysis of full cores versus bottom-ice section sampling, we identify biases in common sampling approaches and provide recommendations for future survey programs: for example, the need to sample fast ice over its entire thickness and to measure auxiliary physicochemical parameters. |
