A lipid budget for Antarctic krill
Microplankton at five sites off South Georgia in January to February 1991 was dominated by a range of diatoms. The haptophyte Phaeocystis was present in three of the five sites but in low abundance only. Diatoms dominated at a more southerly site near the Antarctic Peninsula in March, whereas dinoflagellates dominated at a site near Deception Island. Multivariate analysis allowed the seven site...
متن کاملOxygen budget of a perennially ice-covered Antarctic lake.
A bulk O2 budget for Lake Hoare, Antarctica, is presented. Five years of seasonal data show the lake to be persistently supersaturated with O2. Oxygen is carried into the lake in glacial meltstreams and is left behind when this water is removed as ice by ablation and sublimation. A diffusive loss of O2 from the lake through the summer moat is suggested. Measured values of the total O2 in the...
متن کاملThe Antarctic Atmospheric Energy Budget. Part I: Climatology and Intraseasonal-to-Interannual Variability
The authors present a new, observationally based estimate of the atmospheric energy budget for the Antarctic polar cap (the region poleward of 708S). This energy budget is constructed using state-of-the-art reanalysis products from ECMWF [the ECMWF Interim Re-Analysis (ERA-Interim)] and Clouds and the Earth’s Radiant Energy System (CERES) top-of-atmosphere (TOA) radiative fluxes for the period ...
متن کاملHow Well Do the CMIP5 Models Simulate the Antarctic Atmospheric Energy Budget?
The authors evaluate 23 coupled atmosphere–ocean general circulation models from phase 5 of CMIP (CMIP5) in terms of their ability to simulate the observed climatological mean energy budget of theAntarctic atmosphere. While the models are shown to capture the gross features of the energy budget well [e.g., the observed two-way balance between the top-of-atmosphere (TOA) net radiation and horizo...
متن کاملThe Antarctic Atmospheric Energy Budget. Part II: The Effect of Ozone Depletion and its Projected Recovery
In this study the authors continue their investigation of the atmospheric energy budget of the Antarctic polar cap (the region poleward of 708S) using integrations of the Whole Atmosphere Community Climate Model from the years 1960 to 2065. In agreement with observational data, it is found that the climatological mean net top-of-atmosphere (TOA) radiative flux is primarily balanced by the horiz...
