Global distribution of the decay timescale of mixed layer inertial motions observed by satellite-tracked drifters
MetadataShow full item record
The decay timescale of mixed layer inertial amplitudes has been estimated from satellite tracked drifter trajectories from 1990 to 2004 as the e-folding timescale of the temporal correlation functions. The decay timescales increase with latitude in all basins except the North Atlantic. A beta dispersion model shows that dephasing leads to meridional variations of the decay timescale in the North Pacific and the Southern Ocean, but meridional variations of the buoyancy structure in the North Atlantic act to compensate the beta effect, leading to a lack of meridional variation of the decay timescale in that ocean.

Fate of nitrogen in riparian forest soils and trees : an N-15 tracer study simulating salmon decay Drake, Deanne C.; Naiman, Robert J.; Bechtold, J. Scott (2005-05-23)We introduced a 15N-NH4+ tracer to the riparian forest of a salmon-bearing stream (Kennedy Creek, Washington, USA) to quantify the cycling and fate of a late-season pulse of salmon-N, and, ultimately, mechanisms regulating ...

Coupled ocean–atmosphere offshore decay scale of cold SST signals along upwelling eastern boundaries Spall, Michael A.; Schneider, Niklas (American Meteorological Society, 2016-11-03)A simple analytic model is developed to represent the offshore decay of cold sea surface temperature (SST) signals that originate from wind-driven upwelling at a coastal boundary. The model couples an oceanic mixed layer ...
