Abstract We used a multidisciplinary approach integrating major, trace and rare earth element geochemistry, mineralogy of rocks sediments along with the ionic composition water reservoirs Admiralty Bay, King George Island, to evaluate record water-rock interactions under Maritime Antarctic conditions. Our results showed that compositions streams meltwaters predominantly reflect atmospheric inpu...

In humans, a person's chronotype depends on environmental cues and on individual characteristics, with late chronotypes prevailing in youth. Social jetlag (SJL), the misalignment between an individual׳s biological clock and social time, is higher in late chronotypes. Strong SJL is expected in Uruguayan university students with morning class schedules and very late entertainment activities. Slee...

The suggestion is advanced that the remarkably low static stability of Antarctic surface waters may arise from a feedback loop involving global deep-water temperatures. If deep-water temperatures are too warm, this promotes Antarctic convection, thereby strengthening the inflow of Antarctic Bottom Water into the ocean interior and cooling the deep ocean. If deep waters are too cold, this promot...
