Deep ocean circulation may be a significant factor in determining climate. Here, we describe two long, fully coupled atmosphere-ocean simulations with the NCAR Climate System Model (CSM) for the late Cretaceous (80 Ma). Our results suggest that higher levels of atmospheric CO2 and the altered paleogeography of the late Cretaceous resulted in a surface ocean state temperature, salinity, and circ...

Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract On the basis of model simulations, we examine what information on changes in the strength of the Atlantic Meridional Overturning Circulation (AMOC) can be extracted from associated changes in sea surface height (SSH), s...

Abstract Agulhas leakage, the warm and salty inflow of Indian Ocean water into Atlantic Ocean, is importance for climate-relevant Meridional Overturning Circulation. South Africa, eastward turning Current sheds rings, cyclones filaments order 100 km that carry Cape Basin further Atlantic. Here, we show resolution submesoscale flows 10 in an ocean model leads to 40 % more leakage realistic water...

The western north Atlantic Ocean constitutes a major route for autumnal migrants moving between eastern North America and the Caribbean or South America. Some shorebirds have long been known to use this route (Lincoln, 1939; Hagar, 1966; Palmer, 1968; McNeil and Burton, 1973), and recently Drury and Nisbet (1964) and Nisbet (1970) have stated that the Blackpoll Warbler (Dendroica striata) proba...

[1] This paper presents a comprehensive analysis of the basin-wide inventory of anthropogenic CO2 in the Atlantic Ocean based on high-quality inorganic carbon, alkalinity, chlorofluorocarbon, and nutrient data collected during the World Ocean Circulation Experiment (WOCE) Hydrographic Program, the Joint Global Ocean Flux Study (JGOFS), and the Ocean-Atmosphere Carbon Exchange Study (OACES) surv...

Climatic oscillations throughout the Pleistocene combined with geological and topographic complexity resulted in extreme habitat heterogeneity along the Atlantic coast of Brazil. Inferring how these historic landscape patterns have structured the current diversity of the region's biota is important both for our understanding of the factors promoting diversification, as well as the conservation ...

We measured the carbon monoxide (CO) concentrations in the marine boundary layer and the surface waters of the Atlantic Ocean from 50°N to 50°S during the UK Atlantic Meridional Transect expedition (AMT-7) in October 1998, covering the open ocean and coastal regions. Throughout the cruise track, atmospheric CO concentrations continually decreased southwards in the northern hemisphere with spora...

Geographically MS describes three frequency zones. High frequency areas (prevalence 30+ per 100 000) now comprise most of Europe, Israel, Canada, northern US, southeastern Australia, New Zealand, and easternmost Russia. Medium frequency areas include southern US, most of Australia, South Africa, the southern Mediterranean basin, Russia into Siberia, the Ukraine and parts of Latin America. Preva...

The transfer of upper kilometer water from the Indian Ocean into the South Atlantic, the Agulhas leakage, is believed to be accomplished primarily through meso-scale eddy processes. There have been various studies investigating eddies of the ‘‘Cape Basin Cauldron’’ from specific data sets. The hydrographic data archive acquired during the last century within the Cape Basin region of the South A...
