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 ...
A sea ice process defined by the WMO as: The pressure process by which sea ice is forced in ridges. A ridge is a line or wall of broken ice forced up by pressure. It may be fresh or weathered. The submerged volume of broken ice under a ridge, forced downwards by pressure, is termed in ice keel. Antarctic ridges a commonly point features, whereas they are more often long and linear in the Arctic. The official IHO definition for this in the context of undersea feature names has three meanings:
an elongated narrow elevation of varying complexity having steep sides;
an elongated narrow elevation, often separating ocean basins; and
the linked major mid–oceanic mountain systems of global extent; also called mid–oceanic ridge.

A sea ice term defined by the WMO as: Any break or rupture through very close pack ice, compact pack ice, consolidated pack ice, fast ice, or a single floe resulting from deformation processes. Fractures may contain brash ice and/or be covered with nilas and/or young ice. Length may vary from a few metres to many kilometres.

A sea surface film in which organic accumulation exceeds a threshold such that it becomes visible as a slick, i.e. a sea surface feature that appears as smooth grey spots or stripes in contrast to the surrounding deep blue waters. The smoothing effect is due to the accumulation at the sea–air interface of organic compounds, many of them surface–active, which enhance solar reflection at the surface by damping the capillary waves. Slicks are thought to play a significant role in heat flux and gas exchange, biogeochemical cycles, and pollutant dispersion dynamics as a consequence of the organic enrichment and their location at the boundary between atmosphere and ocean.

A sea surrounded by land and connected to the open ocean by one or more narrow straits. Examples include the Baltic Sea, the Red Sea, and the Black Sea. Compare to epeiric sea and epicontinental sea.

A seasonal and northward flowing current found in the western part of the Bay of Bengal from about January until October. The weak and variable currents found early in the year strengthen with the Northeast Monsoon, exceeding 0.5 m/s by March and ranging from 0.7-1.0 m/s through May and June. This current flows counter to the wind, apparently as an extension of the North Equatorial Current, although a convincing dynamical explanation has yet to be offered. The northward flow gradually weakens with the advent of the Southwest Monsoon, with the currents to the north and close to the shelf beginning to reverse in September. By late October, the East Indian Current has completely reversed into the East Indian Winter Jet.

A seasonal southwestward flowing western boundary current found in the western Bay of Bengal from late October through around late December. It features velocities consistently above 1 m/s as it flows southwestward, eventually turning west and following topographic contours as it passes Sri Lanka and feeds all its waters into the Arabian Sea. In late December its northern part fades, eventually to become the East Indian Current, and the southern part merges with the developing North Equatorial Current.

A second–generation ALACE float designed to correct the design flaws of the latter. The SOLO uses a single–stroke hydraulic pump allowing full up–down control, and eliminates the internal oil bladder.

A self-registering maximum and minimum thermometer invented by James Six (1731?-1793) of England in 1782. It consisted of a U-shaped tube with mercury in the bend, one side filled with alcohol, and the other partially filled. Indices marked the highest and lowest temperatures. This was the most widely used thermometer for taking deep sea temperatures up until the 1870s.
