The R/V METEOR M 66 cruise was carried out primarily in support of the "SFB" 574 (Volatiles and Fluids in Subduction Zones), a Cooperative Research Center dedicated to understanding the budget, reactions, and recycling of volatile elements in subduction zones and their role in climate forcing. To address the short- and long-term variability of the Earth’s climate, the geochemical evolution of the hydrosphere and atmosphere, and related processes that are all connected to the return flow of volatiles and fluids from subduction zones, the SFB 574 is studying the Central American forearc off Costa Rica and Nicaragua (Fig 1). The goals of the initial, oceanographic leg of cruise M 66 were to obtain part of a 2-year time series of the transport of southern hemispheric water through the passages into the Caribean, to study the circulation and variability of the flow in the deep western boundary current and in the interior of the basin, and to calculate time scales of deep water spreading from the Labrador Sea to 16°N.
