Joint Air-Sea Interaction Project

Project Description
The JASIN (Joint Air-Sea Interaction) Project was designed to study
the interaction of the atmospheric and oceanic boundary layers with
the large scale motions of the sea and air.

The primary aims were as follows:

1. to observe and distinguish between the physical processes causing
mixing in the atmospheric and oceanic boundary layers and relate them
to the mean properties of the layers

2. to examine and quantify aspects of the momentum and heat budgets in
the atmospheric and oceanic boundary layers and fluxes across and
between them.

The multiplicity of processes sampled necessitated a large experiment
and JASIN involved 14 ships and 3 aircraft with more than 50 teams of
investigators from 9 countries. Altogether 35 mooring systems were
deployed. The experiment lasted for 2 months from mid-July to
mid-September 1978 and comprised 2 intensive observational phases
preceded by a preparatory test period. The Project took place in the
North Rockall Trough, an area of deep water (1000m - 2000m) several
hundred kilometres off the west coast of Scotland.
