Oceanography

magnetometer

Earth science; Oceanography

A remote sensing instrument capable of identifying sub-surface archaeological features by measuring the difference in their magnetic properties against the surrounding soils.

mesosphere

Earth science; Oceanography

The atmospheric shell in which temperature generally decreases with heights that extend from the stratopause at about 50-55 km to the mesopause at about 80-85 km. Compare to stratosphere and ...

mean sea level

Earth science; Oceanography

The average level of the sea over a period of time, taking into account periodic changes due to tides and other fluctuations (such as wind waves).

geostrophic balance

Earth science; Oceanography

The balance of the horizontal pressure gradient and the acceleration provided by the spinning of Earth; i.e., the Coriolis force. The horizontal pressure gradient arises because of differential ...

littoral

Earth science; Oceanography

The beach, the space between high and low tide marks, or water a little below low water mark.

stratopause

Earth science; Oceanography

The boundary between the stratosphere and the mesosphere. It occurs at an atmosphere height of approximately 50 km; however this depends on latitude. The atmosphere is characterized by a decrease ...

The boundary between the troposphere and stratosphere, usually characterized by an abrupt change of lapse rate. The change is in the direction of increased atmospheric stability from regions below ...
