Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
Overview
A focus of the PolarTREC Southern Ocean Diatoms expedition was to collect water samples and physical profile data using oceanographic technology. Oceanographers rely on the real-time data transferred from the water column to the ship-based computers using a CTD sensor. The CTD measures conductivity (salinity), temperature and depth
This one hour live event is hosted by PolarTREC teacher Mike LeBaron and his team studying sub-glacial lakes and streams. The team is at McMurdo Station, Antarctica. This event was part of the December 2012 Antarctica Day celebration. The team also speaks about the importance of the Antarctic Treaty and scientific investigations.
