Upper Ocean Mooring Data Archive - LOTUS: The Long Term Upper Ocean Study
The Long Term Upper Ocean Study (LOTUS) was a two-year experiment in the North Atlantic, designed to acquire and analyse a continuous set of measurements of currents and temperatures throughout the water column in the open ocean. A total of ten moorings were deployed in about 5365 meters of water.
Funding for this experiment was provided by the Office of Naval Research.

May 1982 through May 1984.
The LOTUS experiment included 10 moorings.
Surface MooringsThe single set of surface data is from 4 moorings, deployed one after the other. Most instrumentation was in the upper 350 meters of water.

Subsurface MooringsThere were 6 subsurface moorings deployed. For each of the 2 years of the experiment, there was 1 fully-instrumented near-surface mooring, with its most shallow instrumentation at about 100m, and 2 sparsely instrumented, very deep moorings. Data from the near-surfce moorings is presented here. Because of different sensor depths, data from the 2 years is presented individually.
