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
Antarctic educator, Mark Walsh, created this video for the PolarTREC 2013 spring online professional development course. This video uses the concept of Density to explore how mountains are built as well as how to throw a good Cinco de Mayo party at McMurdo Station Antarctica. He uses the Dr. Samantha Hansen's Transantarctic Mountains work as an example of mountain building.
Ice Stories is a project from the San Francisco Exploratorium as 'Dispatches from Polar Scientists' as an outreach effort from the 2007-08 International Polar Year. The Antarctic Geology focuses on mountains in East and West Antarctica. Be sure to check out the videos associated on the website "Secrets of Bedrock" and "Mystery Mountains".
