Pelagic Ecosystems
of the Tropical
Atlantic Ocean

 

 

 


Introduction

Dear colleagues,

Although the tropical and subtropical Atlantic is poorly represented in biological data sets readily available to the scientists (http://www.nodc.noaa.gov/OC5/indprod.html), many of you are aware of extremely detailed biological surveys in the region by the National Academy of Sciences of Ukraine, from 1960 to 1990 (Greze 1984; Piontkovski and Landry, 2003; Zuyev et al., 1990).

A minor part of this data, mostly hydrographic information, was released in 1992-1994 in the framework of the GODAR project.
Select aspects of the ecological results have also found their way into the open literature by Western European and US scientists, some of whom were cruise participants. However, the vast majority of the data remained in archives.
By the given CD, the Oceanological Center of the National Academy of Sciences of Ukraine presents an extensive data set which bridges the critical gap in the World Ocean Database (WOD 2001, http://www.nodc.noaa.gov/) for the tropical and subtropical Atlantic. As well, the CD incorporated research articles and full list of Russian references associated with the above data.
One notable aspect of the data is the relative constancy of sampling methods throughout the surveys. In addition, most of the taxonomic analyses of phytoplankton, zooplankton and fish species were conducted under the auspices of the Institute of Biology of the Southern Seas specialists in the taxonomy of the various groups.
The database and research focus on a portion of the Atlantic Ocean that includes all or parts of three biogeochemical provinces defined by A. Longhurst (1998) - the Eastern Tropical Atlantic (ETRA), the Western Tropical Atlantic (WTRA) and the South Atlantic Gyre (SATL). 

Hopefully, this product will contribute important new insights to our understanding of spatial patterns of species diversity and species-climate linkages. We expect that the species inventory, linked to the species database, CTD casts and nutrients would enable its users to engage a developed CD in inter-disciplinary comprehensive analyses of tropical and subtropical ecosystems of the Atlantic Ocean. 

We are grateful to many colleagues from the
Institute of Biology of the Southern Seas, Marine Hydrophysical Institute, Plymouth Marine Laboratory, Stony Brook University and the National Science Foundation (grant # DEB-0203622) for support and cooperation.
