Conductivity-Temperature-Depth (CTD) data collected on board icebreaker Oden during the Oden Southern Ocean 2008/2009 expedition
--------------------------------------------------------------------------------------------------------------------------------

These data were collected onboard the icebreaker Oden during the Oden Southern Ocean 2008/2009 (OSO0809) expedition and are published by the Swedish Polar Research Secretariat. Accompanying meteorological and location data are published at ECDS (https://ecds.se/dataset/meteorological-oceanographic-and-ship-data-from-antarctic-expedition-oso0809-nov-2008-jan-2009)

Notes
-------------------------------------------------------------------------

This directory contains all processed oso08_09 CTD data. Temperature and salinity are calibrated using both pre and post cruise calibration sheets and SeaBird calibration software. Oxygen data are processed for sensor drift and adjustments to bottle data. The later is much large than the earlier. The down trace data of each cast from the best sensors (T1, S1, and O2_1) are reported here. All recognizable spikes have been removed.
