The purpose of this volume is to present new information about this ecosystem so that its role within the Antarctic food-web (and as a sink for carbon dioxide) and its susceptibility to environmental changes can be better understood.Antarctic Sea Ice: Biological Processes, Interactions and ...
1. In Antarctica, a series of parallel valleys lie between the Ross Sea and the East Antarctic Ice Sheet. 本图显示的是在罗斯海和南极洲东部大冰层之间的一系列平行山谷,又称干谷,由于下沉风终年肆虐,来自高纬度又干又冷的气流会将冰雪吹下山坡,吹向海洋。
with maxima up to 16 m. We also find that, on average, 76% of the ice volume is deformed ice. Our surveys indicate that the floes are much thicker and more deformed than reported by most drilling and ship-based measurements of Antarctic sea ice. We suggest that thick ice in the near...
A variety of hypotheses, involving sub-ice-shelf melting, stratospheric ozone depletion and tropical teleconnections, have been proposed to explain the observed Antarctic sea-ice expansion over the period of continuous satellite monitoring and correspond
This work evaluates two distinct calculations of central tendency for sea-ice thickness and quantifies the impact such calculations have on ice volume for the Southern Ocean. The first calculation, area-weighted average thickness, is computed from polygonal ice features and then upscaled to regions....
This riddle is explored here using a global multicategory thick ness and enthalpy distribution sea ice model coupled to an ocean model. Forced by the NCEP–NCAR reanalysis dat a, the model simulates an increase of ? 10 12 m 3 yr ? 1(% yr ? 1) in total Antarctic sea ice volume and ...
