Founded in 1876, Texas A&M University is a U.S. public and comprehensive university offering a wide variety of academic programs far beyond its original label of agricultural and mechanical trainings. It is one of the few institutions holding triple federal designations as a land-, sea- and ...
An eastward current in the Atlantic and Pacific that flows between 5 and 10° S., the limited evidence for which shows it to be much less well developed than the North Equatorial Countercurrent (NECC). In the Indian Ocean the SECC is almost totally confined between the equator and the northern boundary of the South Equatorial Current (SEC) at 4° S. This was first described by Reid (1959) and the evidence is later reviewed by Leetmaa et al. (1981).

An eastward flow emanating from the East Greenland Current (EGC) in the Greenland Sea. Its axis is north of Jan Mayen and centered on 72–74° N. Its position in the winter is often associated with an ice odden, a persistent eastward extension of the East Greenland Ice Stream. The upper layer baroclinic flow shows that about half of the JMC is a wide meander in the EGC and about half continues eastward to close the Greenland Gyre system on the south. Beneath the halocline the meander dissipates and the flow becomes more barotropic, with the barotropic flow steered to the east by the Jan Mayen Fracture Zone. This has also been called the Jan Mayen Polar Current.
Industry:Earth science
An eastward flow in the Atlantic Ocean whose core is located near 200 m depth a few degrees south of the Equator. A satisfactory dynamical explanation for this is as yet nonexistent.
Industry:Earth science
An eastward flow in the Pacific Ocean whose core is located near 600 m depth a few degrees north of the Equator. A satisfactory dynamical explanation for this is as yet nonexistent.
Industry:Earth science
An eastward flowing countercurrent that flows beneath the surface at around 4° N in the North Pacific Ocean. It flows between the eastward flowing North Equatorial Countercurrent (NECC) to the north and the westward flowing South Equatorial Current (SEC) to the south.
Industry:Earth science
An eastward flowing countercurrent that flows beneath the surface east of 155° in the South Pacific Ocean. It flows between the eastward flowing South Equatorial Countercurrent (SECC) to the north and the westward flowing South Equatorial Current to the south.
Industry:Earth science
An eastward flowing current found in the region from 20-26° N. In geostrophic current calculations these currents extend to the bottom of the thermocline and occasionally to 1500 m, while they’ve been identified in ship drift data with speeds reaching 0.15 m/s. They do not exist east of Hawaii and, given also the fact that they are in the middle of the subtropical gyre, are thought to be caused by a modification of the Sverdrup circulation by those islands. No satisfactory explanation has as yet been advanced.
Industry:Earth science
An EC MAST project whose primary objective is to measure the spatial and temporal variability of waves and currents in coastal regions using the full range of state of the art measurement techniques and models. The measurement systems used in this experiment include HF radar, synthetic aperture radar (SAR), satellite altimetry, accelerometers, ADCP, current meters, pressure cells, and X-band ground-based radar since one of the primary goals is the intercomparison of these techniques.
Industry:Earth science
An effort to determine the sources and limits of predictability of warm season precipitation over North American, with emphasis on time scales ranging from seasonal to interannual.
Industry:Earth science
An effort to observe and model mixing along the Hawaiian Ridge, a salubrious location for such an investigation since the topography is steep and energy available in the form of tides that strike the Ridge at nearly normal incidence.
