Modelling interactions of acid–base balance and respiratory status in the toxicity of metal mixtures in the American oyster Crassostrea virginica
Heavy metals, such as copper, zinc and cadmium, represent some of the most common and serious pollutants in coastal estuaries. In the present study, we used a combination of linear and artificial neural network (ANN) ...
Strontium isotopes in Chilean rivers : the flux of unradiogenic continental Sr to seawater
Analyses of Chilean river waters indicate that the average yield of unradiogenic Sr (~ 517 mol Sr km− 2 yr− 1, 87Sr/86Sr ~ 0.7057) from western South America (1,220,853 km2) into the southeastern Pacific Ocean is ~ 2–4 ...
External tagging does not affect the feeding behavior of a coral reef fish, Chaetodon vagabundus (Pisces: Chaetodontidae)
Increasingly, the ability to recognize individual fishes is important for studies of population dynamics, ecology, and behavior. Although a variety of methods exist, external tags remain one of the most widely applied ...
Evolution of the Irminger Current anticyclones in the Labrador Sea from hydrographic data
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2006-06)
The continuous supply of heat and fresh water from the boundaries to the interior of the Labrador Sea plays an important role for the dynamics of the region and in particular, for the Labrador Sea Water formation. Thus, ...
A data archive from Discovery 247, a process study of the Faroe Bank Channel overflow
CTD, XCP and LADCP data acquired during the June 2000 Discovery cruise 247 to Faroe Bank Channel are provided in a data archive that may be accessed by Matlab 7.X.
Examining the effects of mid ocean ridge topography on 3D marine magnetometric resistivity model responses
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2004-06)
Methods which measure seafloor resistivity are uniquely suited to studying hydrothermal circulation in the crust. The magnetometric resistivity (MMR) technique is a galvanic method which uses a bipole current source with ...
Endowments and new institutions for long-term observations
(Oceanography Society, 2007-12)
An ever-increasing volume of publications on the changing ocean environment underscores the requirement for long-term observations to understand and predict ocean and climate change. Such observations must be ...
An assessment of the Atlantic and Arctic sea–air CO2 fluxes, 1990–2009
(Copernicus Publications on behalf of the European Geosciences Union, 2013-01-29)
The Atlantic and Arctic Oceans are critical components of the global carbon cycle. Here we quantify the net sea–air CO2 flux, for the first time, across different methodologies for consistent time and space scales for the ...
A differential pressure instrument with wireless telemetry for in-situ measurement of fluid flow across sediment-water boundaries
(Molecular Diversity Preservation International, 2009-01-09)
An instrument has been built to carry out continuous in-situ measurement of small differences in water pressure, conductivity and temperature, in natural surface water and groundwater systems. A low-cost data telemetry ...
Skill assessment for coupled biological/physical models of marine systems
Coupled biological/physical models of marine systems serve many purposes including the synthesis of information, hypothesis generation, and as a tool for numerical experimentation. However, marine system models are ...
