Abstract To clarify the impacts of basal melting Antarctic ice sheet and biological productivity on biogeochemical processes in coastal waters, concentrations dissolved inorganic carbon (DIC), total alkalinity (TA), nutrients, chlorophyll a , stable oxygen isotopic ratios (δ 18 O) were measured from offshore slope to front Totten Ice Shelf (TIS) during spring/summer 2018, 2019, 2020. Modified Circumpolar Deep Water (mCDW) intruded onto continental shelf off TIS flowed along bathymetric...
Abstract Sea ice, which forms in polar and nonpolar areas, transmits light to ice-associated (sympagic) algal communities. To noninvasively study the distribution of sea-ice algae, empirical relations estimate its biomass from under-ice hyperspectral irradiance have been developed Arctic Antarctica but lack for regions. This examines relationships between normalised difference indices (NDI) calculated transmittance sympagic Saroma-ko Lagoon. We analysed physico-biogeochemical properties snow...
