The intensive hydrographic survey conducted in 1978 as part of the POLYMODE Local Dynamics Experiment (LDE) revealed a large number of anomalous water parcels at various depths near 31°N, 70°W in the ...
Small Water-Property Transporting Eddies：Statistical Outliers in the Hydrographic Data of the POLYMODE Local Dynamics Experiment
Local Dynamics Experiment Hydrographic Data
2009/1/10
Hydrographic measurements from the POLYMODE Local Dynamics Experiment (LDE; 31°N, 69.5°W; May–July 1978) are examined for highly anomalous, outlying observations of salinity, oxygen and vortex stretch...
Structure and Origin of a Small Cyclonic Eddy Observed during the POLYMODE Local Dynamics Experiment
Small Cyclonic Eddy Local Dynamics Experiment Sargasso Sea
2009/1/10
In the POLYMODE Local Dynamics Experiment (31°N; 69.5°W) a small cyclonic eddy was discovered and mapped. The eddy was characterized by an upward doming of isotherms in the upper part of the main ther...
