Summary

Abstract:
The Equatorial Pacific Process Study (EQPAC) was conducted along 140 deg W longitude during 1992. Four cruises took place: February 3 - March 9, March 19 - April 15, August 5 - September 18, and September 24 - October 21. A fifth benthic cruise and sediment trap legs were added. During the first cruise (TT007), 15 stations were occupied along 140 deg W longitude from 12 deg N latitude to 12 deg S latitude. During the second cruise (TT008), data were collected at 8 stations along 140 deg W longitude from 9 deg S latitude to 9 deg N latitude. During the third cruise (TT011), data were collected at 15 stations along 140 deg W from 12 deg N latitude to 12 deg S latitude. During the fourth cruise (TT012), data were collected at 5 stations along 140 deg W longitude from 17 deg S latitude to the equator. Dissolved and particulate trace metals were filtered at 0.4 micrometers. Trace metals measured include dissolved cadmium (Cd), dissolved cobalt (Co), dissolved copper (Cu), dissolved iron (Fe), dissolved nickel (Ni), dissolved lead (Pb), dissolved zinc (Zn), particulate aluminum (Al), particulate iron (Fe), and particulate manganese (Mn). The particulate constituents were extracted with a 25% acetic acid leach, refractory constituents by total digestion. The trace metal data were only collected during the second (TT008) and fourth (TT012) cruises. The data is public domain and can be retrieved on-line at "http://usjgofs.whoi.edu/jg/dir/jgofs/" [The information in this summary was taken from the JGOFS World Wide Web pages.] |
