The Oceanography and Ecology of the Ross Sea

Annual Review of Marine Science, 2014
The continental shelf of the Ross Sea exhibits substantial variations in physical forcing, ice cover, and biological processes on a variety of time and space scales. Its circulation is characterized by advective inputs from the east and exchanges with off-shelf regions via the troughs along the northern portions.

An Apparent Decrease in the Prevalence of "Ross Sea Killer Whales" in the Southern Ross Sea

Aquatic Mammals, 2009
Killer whales (Orcinus orca), both ecotype-B and -C, are important to the Ross Sea, Antarctic ecosystem. The ecotype-C is referred to as “Ross Sea [RS] killer whale.” Herein, we review data on occurrence patterns and diet of RS killer whales and present new information on numbers observed in the southwestern Ross Sea, 2002-2003 to 20082009 austral ...

Kerogen Recycling in the Ross Sea, Antarctica

Science, 1974
Analyses of the stable isotopes of the organic carbon and microscopic examination of the sediment particles suggest that up to 90 percent of the organic matter in Ross Sea sediments is derived from the igneous and ancient metamorphic and sedimentary rocks that are being glacially eroded on the Antarctic continent and transported seaward.

Picoplankton BIOMASS in the Ross Sea (Antarctica)

Polar Biology, 1993
Spatial distribution of picoplankton in the Ross Sea was studied. The authors discuss the biomasses of various picoplanktonic-sized fractions and of bacterial cells between 0.2 and 2.0 μm capable of growing on Marine Agar 2216 (Difco). Picoplankton having a cellular diameter cf between 1.0 and 2.0 μm (PP1) generally predominate, accounting for 73% of ...

Tides of the Ross Sea and Ross Ice Shelf cavity

Antarctic Science, 2003
Two new ocean tide models for the Ross Sea including the ocean cavity under the Ross Ice Shelf, are described. The optimum model for predicting ice shelf surface height variability is based on assimilation of gravimetry-derived tidal constituents from the Ross Ice Shelf.

Chlorofluorocarbon distribution in the ross sea water masses

Chemistry and Ecology, 2004
Chlorofluorocarbon (CFC11, CFC12 and CFC113) data, collected during the 2000-2001 austral summer, within the framework of the activities of the Climatic Long-Term Interactions for the Mass-Balance in Antarctica (CLIMA) Project of the Italian National Program for Antarctic Research (PNRA) in the Ross Sea, are discussed in the context of hydrographic ...

The Ross Sea

2009
We present budgets of carbon and nitrogen for the Ross Sea, Antarctica. The novelty of this study consists in estimating both vertical water-column to sedimentary fluxes as well as horizontal exchanges due to water mass lateral transport between the continental shelf and the open ocean.

The ornithology of the Ross Sea

Journal of the Royal Society of New Zealand, 1981
Abstract Knowledge of the recent history of antarctic glaciation, sea‐ice cover and temperatures suggests that the Ross Sea area has been habitable by birds for some 10,000 years. However, the glaciers in McMurdo Sound precluded colonisation there until about 6,000 yr B.P.

Ross Ice Shelf Sea Temperatures

Science, 1979
Two 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.

Spring Phytoplankton Production in the Western Ross Sea

Science, 1994
Coastal zone color scanner (CZCS) imagery of the western Ross Sea revealed the presence of an intense phytoplankton bloom covering >106,000 square kilometers in early December 1978. This bloom developed inside the Ross Sea polynya, within 2 weeks of initial polynya formation in late November.
