History of the Site:ESTOC was initiated in 1994 about 100 km north of the Canary islands and in 3618 m water depth. Its intention is to create a long time series on an inter- and multidisciplinary basis in order to monitor and help understanding oceanic long-term variability in the North atlantic's subtropical gyre in conjunction with the Bermuda station BATS. It is an open ocean site in the sense that it is located well outside the highly variable eastern boundary with its strong coastal upwelling regime (although interaction with this regime exists), is deep enough to encompass the eastern subtropical North Atlantic's major water masses including the North Atlantic Deep Water (however not the AABW), is windward of the Canary Islands to avoid wake effects of both the major currents and winds (Canary Current and Northeast Trade), and is far enough from coasts and islands (the Selvages 100 km northwards are very small and flat) to serve as reference for satellite images and altimetry. Thus, it is expected that long-term observations at ESTOC represent open-ocean eastern subtropical North Atlantic conditions and variability. Finally, ESTOC is easy to reach by and be serviced with small research vessels. |
