A hole was drilled through the Ross Ice Shelf 450 kilometers from the barrier. Scientific sampling through this hole revealed a sparse population of crustaceans, fish, and microbial biomass. The seabed consists of mid-Miocene glaciomarine mud. Geothermal heat flow is average.

Modelling ice-shelf/ocean interaction
2023The effect of climate change on the mass balance of ice shelves and bottom water formation is investigated using a terrain-following three-dimensional numerical ocean model. The Regional Ocean Modeling System was modified to simulate the thermodynamic processes beneath ice shelves, including direct basal processes and frazil ice dynamics.

GEOLOGY Several small ice shelves around the Antarctic Peninsula retreated during the late 20th century due to regional climate warming. Did similar retreats occur through natural climate variability during the past 10,000 years. Pudsey and Evans have now addressed this question by studying the history of the Prince Gustav Channel ice shelf.

Ross Ice Shelf temperatures support a history of ice-shelf thickening
Nature, 1979The ice sheet in West Antarctica is grounded on a sub-sea level basin in the Antarctic continental shelf. At the seaward margins, where ice thicknesses are reduced sufficiently to attain neutral bouyancy, floating ice shelves form. The two largest are the Ross and Ronne ice shelves (Fig. 1).

Ross Ice Shelf Sea Temperatures
Science, 1979Two temperature profiles recorded by a sensitive bathythermograph at the Ross Ice Shelf Project site (82°22.5′S, 168°37.5′W) are presented. From the shape of the profiles it is concluded that an inflow of water at intermediate depths provides a source of heat to drive a regime in which ice is melted from the interface at a depth of 360 meters.

Large ice masses such as ice sheets and ice shelves change as the Earth's climate changes, and can serve as indicators of past climate variation. In his Perspective, Fahnestock discusses observations reported by Rott et al. in the same issue, which show the dramatic collapse

Arctic ice shelves are microbial ecosystems with a rich biodiversity. Until recently, polar ice shelves were seen as mostly abiotic glaciological features, however they are oases for life, with snow, meltwater pools and sediments providing cryohabitats for microbiota.

INTRODUCTION Of all Antarctic glacial features, none is as characteristic or as distinctive and none has excited as much interest and as much speculation from explorers, as the areas of shelf ice which occupy protected or partly protected areas about the continent. The best known and largest of these is the Ross Shelf Ice, which extends northward from
