Direct measurements of the mean flow and eddy kinetic energy structure of the upper ocean circuletion in the NE Atlantic
(American Geophysical Union, 2005-07-19)
The upper ocean circulation in the sub-polar northeast Atlantic has been a challenge to quantify due to strong and variable wind-forcing, and strong and variable deep currents that lead to large uncertainties in the use ...
Seasonal variation in marine C:N:P stoichiometry: can the composition of seston explain stable Redfield ratios?
(Copernicus Publications on behalf of the European Geosciences Union, 2011)
Seston is suspended particulate organic matter, comprising a mixture of autotrophic, heterotrophic and detrital material. Despite variable proportions of these components, marine seston often exhibits relatively small ...
Dissipation measurements using temperature microstructure from an underwater glider
Microstructure measurements of temperature and current shear are made using an autonomous underwater glider. The glider is equipped with fast-response thermistors and airfoil shear probes, providing measurements of dissipation ...
Atmospheric boundary layers in storms: advanced theory and modelling applications
(European Geosciences Union/Copernicus, 2005-03-29)
Turbulent planetary boundary layers (PBLs) control the exchange processes between the atmosphere and the ocean/land. The key problems of PBL physics are to determine the PBL height, the momentum, energy and matter fluxes ...
The effect of wind speed products and wind speed-gas exchange relationships on interannual variability of the air-sea CO2 gas transfer velocity
The lack of a firm relationship between wind speed (U10) and gas transfer velocity (k) is considered to be one of the factors that hinders accurate quantification of interannual variations of ocean–atmosphere CO2 fluxes. ...
Heat flux variations in the eastern Norwegian Atlantic Current toward
(American Geophysical Union, 2005-07-21)
Some aspects of the work of V.W. Ekman
(Cambridge University Press, 2006-01)
The climatic conditions in theArctic, and observations of the wind-induced drift of ice made in connexion with Fridtjof Nansen’s Fram expedition, led to the discovery 100 years ago by Vilhelm Bjerknes’ pupil, V.W. Ekman, ...
Complementing Scientific Monsoon Definitions with Social Perception in Bangladesh
(American Meteorological Society, 2015-01)
The monsoon onset is a critical event in the Bangladesh calendar, especially for the domestic agricultural sector. Providing information about the monsoon onset for the past, present, and future has potential benefit for ...
Global observed changes in daily climate extremes of temperature and precipitation
(American Geophysical Union, 2006-03-15)
A suite of climate change indices derived from daily temperature and precipitation data, with a primary focus on extreme events, were computed and analyzed. By setting an exact formula for each index and using specially ...
Topographic effects on CO2, diffusion and dissolution from the seafloor
At 3000 meters depth liquid CO2 is denser than seawater and hence will be stored as a “lake” on the deep ocean floor, which is expected to gradually be dissolved in seawater. Ocean currents and turbulence will influence ...
