CTD mocness data collected during the Census of Marine Zooplankton cruises RHB0603 (4/10/2006 to 4/30/2006) in the Sargasso Sea and cruise PS24_1 (11/5/2007 to 11/21/2007) off the Atlantic coast of Africa

The ctd MOCNESS-1 data were collected during the RHB0603 cruise in the Sargasso Sea from April 10 to April 30, 2006 and during the PS24_1 off the Atlantic coast of Africa from November 5 to November 21, 2007. The MOCNESS-1 has nine rectangular nets (1m x 1.4 m) which are opened and closed sequentially by commands through conducting cable from the surface (Wiebe et al., 1976). The underwater unit sends a data frame, comprised of temperature, depth, conductivity, net-frame angle, flow count, time, number of open net, and net opening/closing, to the deck unit in a compressed hexadecimal format every 2 seconds and from the deck unit to a microcomputer every 4 seconds. Temperature (to approximately 0.01 deg C) and conductivity are measured with SEABIRD sensors. In addition, data were collected from three other sensors attached to the frame: the Transmissometer, the Fluorometer, and the Downwelling light sensor. A SeaBird underwater pump was also included in the sensor suite.
