dead-water phenomenon

Earth science; Physical oceanography

A phenomenon caused by a thin layer of fresh meltwater overlaying an otherwise salty sea. It is exceptionally hard to propel a boat (by rowing or any other method) in such a ...

slippery sea

Earth science; Physical oceanography

A phenomenon occurring in the wind-driven layer at the surface of the sea. In conditions of strong surface heating, a well-mixed warmer (and lighter) layer if formed, which is of ...

katabatic wind

Earth science; Physical oceanography

A phenomenon that originates with a layer of cold air forming near the ground on a night with clear skies and a low pressure gradient. If the ground is sloping, the air close to ...

evaporative cooling

Earth science; Physical oceanography

A phenomenon wherein the evaporation of water from saturated air (when, for example, it mixes with drier air) cools the air due to the absorption of latent heat.

Navy Remote Ocean Sensing Satellite (NROSS)

Earth science; Physical oceanography

A planned mission that apparently collapsed under its own financial weight and never got off the ground.

Niskin bottle

Earth science; Physical oceanography

A plastic sampling bottle with water tight clsoures at top and bottom used to collect seawater samples for discrete chemical and biological measurements. It is equipped with a ...

Coastal Observation and Simulations with Topography (COAST)

Earth science; Physical oceanography

A PMEL program. COAST was conducted from Nov. 30 to Dec. 15, 1993 and the purpose was to collect the observations needed to document and ultimately anticipate the influence of ...
