Geosecs Atlantic Set

The GEochemical Ocean SECtions Study during 1972-78 occupied 454 stations throughout the World Ocean for the purpose of collecting measurements of the "geochemical properties of the oceans with respect to large-scale circulation problems". GEOSECS marks the first deep water use of the Neil Brown CTD and the development of many of the present-day analytic techniques used in seawater analyses. We have assembled a few hydrographic sections from this global program.

SAVE Atlantic Set

The South Atlantic Ventilation Experiment (1987-1988) was a follow on to the Transient Tracers in the Ocean program North Atlantic Study. The objective in this case was to collect sections of profiles of hydrographic and geochemical tracers, both natural and anthropogenic, to study the large scale circulation and ventilation of the South Atlantic Ocean. We have assembled hydrographic sections from this program.

TTO Atlantic Set

The objectives of the Transient Tracers in the Ocean North Atlantic Study (1981) and Tropical Atlantic Study (1982-1983) were to collect sections of profiles of hydrographic and geochemical tracers, both natural and anthropogenic, to study the large scale circulation and ventilation of the North and tropical Atlantic Ocean. We have assembled several hydrographic sections from this program.

Pre-WOCE Basin Scale Sections

During the time the original OceanAtlas applications were distributed, some of the best of the pre-WOCE basin scale hydrographic sections were assembled and translated into OceanAtlas format. Although the high-resolution WOCE Hydrographic Program sections cover a greater portion of the World Ocean, and although the WHP data are generally of higher resolution and contain measurements of additional water properties, many of these earlier sections retain significant value, both for comparison with WHP data and on their own as excellent sections. We present a selection of these pre-WOCE sections via a graphic interface. (A few of the pre-WOCE sections were adopted by WOCE and so appear as both pre-WOCE and WOCE data.)

Arctic/Nordic

A selection of Arctic Ocean and Nordic Sea sections (CTD and bottle data) from various expeditions beginning in 1982.
