CTD data collection simultaneously with MOCNESS plankton tows, Georges Bank/Gulf of Maine region, 1992-1999, GLOBEC

CTD observations were collected simultaneously with the towing of
the multi-net MOCNESS plankton sampler (net size units of 0.25, 1 and
10 square meters) during 46 cruises to the Georges Bank/Gulf of Maine
region. Observations cover the period 1992 thru 1999, however, the
in-depth coverage is for the years 1995 thru 1999. These data
represent the water column conditions at the time/depth each net was
open along the towed track. Parameters reported are: lat., long.,
depth, temperature, salinity, potential density, potential
temperature, and to a lesser degree fluorescence, light transmission,
and dissolved oxygen.

A number of high resolution net parameters (net angle, flow counts,
horizontal net velocity, and vertical net velocity) are reported along
with the CTD data stream. These parameters document the status the
net over the duration of the tow and should be taken into
consideration when interpreting the plankton catch data.
