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 ...
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 ...
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 ...
tropopause
Earth science; Oceanography
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 ...
