Conductivity, Temperature, Depth (CTD) Data Measured during the JGOFS Equatorial Pacific Process Study (EQPAC)

During the fourth cruise (TT012), data were collected at 5 stations along 140 deg W longitude from 17 deg S latitude to the equator. During the fifth benthic cruise (TT013), data were collected at 16 stations along 140 deg W from 12 deg S latitude to 9 deg N latitude. CTD casts at each station provided the following information: sample depth, depth reported as pressure, temperature, conductivity, salinity, potential temperature, potential density, sigma-t, fluorescence, particle beam attenuation, and photosynthetically available radiation (PAR).

The depth of the ocean mixed layer was also reported. The mixed layer is defined as a density increase of 0.03 density units from the first surface value. The data is public domain and can be retrieved on-line at "usjgofs.whoi.edu/jg/dir/jgofs/" [The information in this summary was taken from the JGOFS World Wide Web pages.]
