A basin in the North Atlantic Ocean defined to the east by Greenland, the west and south by the Mohn Ridge, and to the north by Fram Strait. It has two abyssal plains separated by the Greenland Fracture Zone (at about 0° W, 76° N), with the Boreas plain to the north being smaller and shallower (around 3200 m) than the Greenland plain to the south (around 3600 m). The Greenland Sea is completely contained within the confines of the Greenland Basin.

A bay formed by the two northern arms of the island of Halmahera in the Australasian Mediterranean Sea. It is located at about 1° N and 128° W and is considered part of the Halmahera Sea. It is composed of an inner basin 500 m deep separated from the outer depression by a shallow sill ranging from 40-50 m in depth. The shallow sill results in oxygen concentrations within the bay decreasing with depth until they reach zero below 400 m, with hydrogen sulfide becoming important near the bottom.

A body of water in the North Atlantic recognized as such for oceanographic if not official purposes. It lies roughly between the east coast of Greenland and the west coast of Iceland, with the Labrador Sea on its southwest corner and the Greenland Sea to the northeast. The southern boundary is marked by hydrographical rather than geographical features. The basin of this sea is mostly occupied by the eastern part of the Labrador Basin which ranges up to 4600 m in depth. The chief circulation feature is the Irminger Current.

A bottom sampler used for quantitative studies of foraminifera, designed to take a short core of the upper sediment layers without disturbing the surface layer. This sampler, first used in 1951, is a short weighted tube with a removable lining tube and a replaceable cutting edge. The liner is a clear plastic tube with a diameter of 3.5 cm. It can be operated with a light winch in depths up to 500 m when weighted with 35-40 pounds of molded lead, and to depths of 4600 m in more cohesive sediments.
Industry:Earth science
A branch of applied mathematics which determines by observation and measurement the exact positions of points and the figures and areas of large portions of the earth’s surface, the shape and size of the earth, and the variations of terrestrial gravity.
