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 ...

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.

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 ...

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.

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.

A recount of Ross Sea waters

Deep Sea Research Part II: Topical Studies in Oceanography, 2009
Abstract Oceanographic observations within the Ross Sea have grown dramatically in recent years, both in number and quality. This has prompted a parallel recount of the circulation and structure of all water masses in the southwestern continental margins of the Pacific Ocean.

Adelie penguin colonies, Ross Sea, Antarctica

2023
In this study, we use metagenomic sequencing of soils/sediments to reconstruct Adélie penguin populations, diet and microbiota throughout the Ross Sea over the past 6000 years. Ornithogenic soil samples representing 15 active and abandoned Adélie penguin sites across the entire extent of the Ross Sea coastline (Ross Island to Cape Adare) were collected

Observations of sea‐level variability in Ross Sea, Antarctica

New Zealand Journal of Marine and Freshwater Research, 2003
Abstract Data from a new sea‐level recorder station at Scott Base on Ross Island and from a long‐established sea‐level recorder at Cape Roberts are analysed for tides and storm surge. Tides are primarily diurnal and their amplitude reduces to almost zero every 13.66 days, corresponding to the Moon's crossing of the equator. Global tide models are shown
