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 data and information resource for snow and ice processes, especially for interactions among snow, ice, atmosphere and ocean. This is one of the DAACs.
Industry:Earth science
A data center charged with the collection, dissemination, and use of volunteer observing ship (VOS) XBT data for the Atlantic Ocean to satisfy WOCE objectives in the upper part of the water column.
Industry:Earth science
A data center commissioned in 1988 within IODE to acquire the physical and chemical data obtained by the international scientific community in cruises and research programs carried out in the Southern Oceans, control their quality, store them in standard format, and distribute them upon request. This center is a part of CEADO.
Industry:Earth science
A data center that maintains information on WOCE, TOGA, research ships and cruise schedules, and other oceanographic information sources.
Industry:Earth science
A decomposition solution procedure based on the eigenvectors of the linearized dynamical equations, i.e. an inherently linear concept. For example, the equations of large-scale motion in the atmosphere or ocean yield a sum of normal mode solutions for which each has a fixed vertical structure and behaves in the horizontal dimension and in time in the same way as a homogenous fluid with a free surface. Assuming the validity of the assumptions leading to the normal mode solution, the complete solution to the original differential equation is then approximated as a sum of the normal mode solutions. This technique can be applied to either a continuously or discretely stratified ocean model, with the former yielding an infinite set of normal modes and the latter a finite number of modes.

A deep reaching passage with a sill depth of about 2200 m separating the Arctic Ocean to the north from the Nordic Seas to the south. This is the primary path for water exchanges between these two oceanic regions.

A deep submersible commissioned on June 5, 1964 at the Woods Hole Oceanographic Institution. It has been used for over a thousand research and rescue missions in the years since it was first launched, 2http://www.abdn.ac.uk/ nhi648/alipor.htm 20 most from aboard the tender ship Atlantis II, which was retired from that duty in 1996.
Industry:Earth science
A deep water mass found over the slopes of the Iceland– Scotland Ridge in the Iceland Basin. The typical characteristcs at around 20°W are Θ = 2.5°C and S = 34.98. The main source for ISOW is assumed to be the NSDW found below the permanent pycnocline in the Norwegian Sea. The O2 and Si concentrations in ISOW are also slightly lower than in NSDW.
Industry:Earth science
A deep-sea channel that connects the Hatteras Abyssal Plain to the Nares Abyssal Plain in the North American Basin. This is an important passasge for northward traveling deep water formed in the Antarctic. This is also known as the Vema Channel.
Industry:Earth science
A deep-sea sediment composed of at least 30% of the remains of siliceous radiolarians. These sediments occur in the equatorial Pacific and Indian ocean regions where the depth exceeds the carbon compensation depth and therefore aren’t overwhelmed by calcareous ooze. These form deep deposits covering 1-2% of the ocean floor, and are a type of siliceous ooze along with diatom ooze.
