Toward an optimal inversion method for synthetic aperture radar wind retrieval
(American Geophysical Union, 2002-08-01)
In recent years, particular efforts have been made to derive wind fields over the oceans from synthetic aperture radar (SAR) images. In contrast with the scatterometer, the SAR has a higher spatial resolution and therefore ...
Variability at Ocean Weather Station M in the Norwegian Sea
(International Council for the Exploration of the Sea, 2003)
Time series of temperature and salinity from Ocean Weather Station M are analysed for periodic cycles of interannual to decadal scale. Time evolutions of the spectra show various spectral peaks at all depths, but none of ...
Diagnosing ocean tracer transport from Sellafield and Dounreay by equivalent diffusion and age
(Science Press, 2008-09-27)
A simple approach for estimating the equivalent diffusion for diagnosing tracer transport is proposed. Two different expressions are derived; one is based directly on an analytical solution of the two-dimensional ...
Passive tracers and active dynamics - a model study of hydrography and circulation in the northern North Atlantic
(American Geophysical Union, 2006-08)
A long-standing problem in oceanography has been to understand the relationship between what can be measured in the ocean, such as hydrography, and what cannot, such as the strength and structure of the complete ...
Sea ice investigations in the Laptev Sea area in late summer using SAR data
(The Canadian Aeronautics and Space Institute, 2001-10)
The Laptev Sea area, including the Vilkitsky Strait, is an important part of the Northern Sea Route where the presence of sea ice makes navigation difficult even in the summer season. The objective of this study was therefore ...
Indian Ocean: Validation of the Miami Isopycnic Coordinate Ocean Model and ENSO events during 1958–1998
(American Geophysical Union, 2002-05-25)
In the Indian Ocean, in situ data are sparse both in time and space. Therefore, numerical models are one of the major tools for further understanding of the ocean circulation. We have implemented, validated, and done a 40 ...
Greenland Ice Sheet Elevation Ehange in Winter and Influence of Atmospheric Teleconnections in the Northern Hemisphere
(Institute of atmospheric physics, Chinese academy of sciences, Science press, 2009-11-16)
Decreasing Arctic Sea Ice Mirrors Increasing CO2 on Decadal Time Scale
(Institute of Atmospheric Physics, Chinese Academy of Sciences, 2008-11-16)
Arctic sea ice is a keystone indicator of greenhouse-gas induced global climate change, which is expected to be amplified in the Arctic. Here we directly compare observed variations in arctic sea-ice extent and CO2 since ...
Recent and future changes of the Arctic sea-ice cover
(American Geophysical Union, 2008)
The present and future state of the Arctic sea ice cover is explored using new observations and a coupled one dimensional air–sea–ice model. Updated satellite observations of Fram Strait ice-area export show an increase ...
