Said of a vessel when the depth of water can be measured by the lead (within the 100 fathom curve).

A feeble oscillatory disturbance of the earth's crust, detectable only by very sensitive seismographs. Certain types of microseisms seem to be closely correlated with pressure disturbances. See microbarm.

The top of a wave.

When all money in a portfolio is invested in securities as opposed to retaining some cash, it is.

The surroundings or conditions (physical, chemical, mechanical) in which a material exists.

Factor for a loading condition that displaced the crack faces in a direction normal to the crack plane (also known as the opening mode of deformation).

Instrument for measuring the mean intensity of glo global solar radiation (direct and diffuse) near the earth's surface in a specified time interval.

The process by which water in air changes from a vapor to a liquid due to a change in temperature or pressure; occurs when water vapor reaches its dew point (condensation point); also used to express the existence of liquid water on a surface.

The duration and periodicity of the operation of a device.

Same as atmometer.

The process of forcing, either manually or automatically, a wind turbine's blades out of the direction of the wind in order to stop the blades from turning.
