ctd 93mar Temperature and salinity vertical profiles. The sampling at 5 km intervals might be in a box pattern between stations and also 5km on either side of the transect lines. Additional studies include profiles across the shelf breadth at 5 km intervals to depths at least of 2000m. depth (m) temperature (degC) salinity (ppt) potential temperature (degC) density (kg/m3) sigmat (kg/m3) dynamic heighta (dynamic_meters) buoyency frequency (rad2/sec2) The stations are separated by 5km and measurements are reduced to one observation per meter. The CTD system on the Polar Duke is a SesBird SBE9 with a pumped salinity sensor. SeaBird software is used to reduce the raw observations to useable units. The programs are used in the following order with the parameters as suggested in the software manual: DATCNV, SPLIT,WILDEDIT, FILTER, ALIGNCTD, CELLTM, LOOPEDIT,BINAVG, DERIVE. Calibration files (.con) are included. The complete binary and .cnv files are saved. Only the downcast is reduced to bin averaged values. The attempt is to put two meaurements within the dynamical radius of deformation, which in this area ranges from 10 to 15 km. This is an attempt to oversample in the horizontal and determine the correct sampling scale for the Bellingshausen Shelf environment. temperature, salinity, ctd, potential temperature Two types of files are submitted: data at one meter Two types of files are submitted: converted files (.cnv) which are produced by the seabird postprocesseing software and standard depth files (.std) which are created by spline interpolation of the temperature and salinity to standard depths. Each of these file types is submitted in the lter headered format, with descriptions of the variables that are included. The .cnv files have temperature, pressure, conductivity, salinity, potential temperature, depth along with scan numbers and numbers of scans per data item. The .std files have potential temperature,depth, salinity, potential density relative to the surface, specific volume anomaly, dynamic height anomaly and potential energy anomaly (Q). The transport between stations (in Sverdrup) can be obtained by dividing the difference of the Q values at the two stations by the coriolis parameter times 10000. This estimate is independent of the separation distance of the stations. Unix, ODU online LTER ~lter/lterdata/93mar/ctd Eileen E.

SeaBird Data Acquisition Software Version 4.015. Salinity samples are taken near the bottom in deep water to calibrate the salinity sensor. The ctd was calibrated in 1992. Bottle salinities are determined by the AutoSal at Palmer Station. Core measurments available after two years.
