Antarctic krill (hereafter krill) is the key species of the Antarctic marine ecosystem as well as a target of commercial fishery in the Southern Ocean, which compels careful predictions about potential impacts of Ocean Acidification (OA)…
Lead (Pb) isotopic compositions and concentrations, and barium (Ba) and indium (In) concentrations have been determined at monthly resolution in five Law Dome (coastal Eastern Antarctica) ice core sections dated from ~1757 AD to ~1898 AD. [`]…
Black carbon (BC), the primary light-absorbing aerosol in the atmosphere, is emitted by the incomplete combustion of biomass and fossil fuels affecting the radiative balance of the atmosphere. As a contributor to climate change, BC may rival greenhouse gases such as methane.
The Antarctic ice cap is a unique vantage point from which to … observe the global background of black carbon aerosol (BC). Far … removed from sources, BC in the Antarctic atmosphere is largely … due to biomass burning at low- to mid-latitudes modulated by … upper tropospheric…
