STRONTIUM 90 IN NORTH ATLANTIC SURFACE WATER [PDF]

Proceedings of the National Academy of Sciences, 1957
Nuclear fission explosions since 1945 have resulted in the world-wide dissemination of detectable amounts of /sup 90/Sr. Since the isotope has been delivered as fallout to surface layers only, its concentration can be used to study vertical mixing of ocean waters. Preliminary results of this study are presented, but no conclusions have been reached.

Circulation characteristics in three eddy-permitting models of the North Atlantic [PDF]

, 2001
A systematic intercomparison of three realistic eddy-permitting models of the North Atlantic circulation has been performed. The models use different concepts for the discretization of the vertical coordinate, namely geopotential levels, isopycnal layers,

Climatic impacts of fresh water hosing under Last Glacial Maximum conditions: a multi-model study [PDF]

Climate of the Past, 2013
Fresh water hosing simulations, in which a fresh water flux is imposed in the North Atlantic to force fluctuations of the Atlantic Meridional Overturning Circulation, have been routinely performed, first to study the climatic signature of different ...

Enhanced carbon dioxide outgassing from the eastern equatorial Atlantic during the last glacial [PDF]

, 2014
Biological productivity and carbon export in the equatorial Atlantic are thought to have been dramatically higher during the last glacial period than during the Holocene.

Decadal acidification in the water masses of the Atlantic Ocean [PDF]

Proceedings of the National Academy of Sciences, 2015
Significance We provide the first (to our knowledge) observation-based acidification trends in the water masses of the Atlantic basin over the past two decades and compare them with climate model results. Observations and model output confirm that pH changes in surface layers are dominated by the anthropogenic component.

The Eastern Atlantic Basin Pathway for the Export of the North Atlantic Deep Waters

Geophysical Research Letters, 2021
AbstractThe North Atlantic deep water (NADW), according to the classic ocean circulation theory, moves southward as a deep western boundary current (DWBC) even though it may veer into interior and then rejoin DWBC when encountering regional circulation features, such as eddy‐driven recirculation. In potential vorticity dynamics, the eastern side of the

Horizontal and vertical distribution of mesozooplankton species richness and composition down to 2,300 m in the southwest Atlantic Ocean

Zoologia (Curitiba), 2014
We describe the species richness, distribution and composition of mesozooplankton over the continental shelf and slope, and in the water masses in the Campos Basin, southwest Atlantic Ocean. We analyzed the mesozooplankton from two oceanographic cruises (

Mercury in North-Eastern Atlantic Ocean Water [PDF]

Nature, 1971
FEW measurements have been made of the concentration of mercury in sea water and there are considerable differences in the values reported. High values of 1.6 to 3.6 µg total Hg/l. for oxidized samples from Minamata Bay, Japan1, probably reflect the serious pollution of that area2.

Coping With Production Risk: Effects of Sown Plant Diversity on the Attractiveness of Crop Insurance in Grasslands

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Increased frequency of extreme weather events, particularly droughts, threatens grassland farming by destabilizing yields and farms' economic viability. We examine, theoretically and through numerical simulations, how sown plant diversity (natural insurance) influences the attractiveness of indemnity and drought index insurance (formal ...
