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
Permafrost is a key cryospheric component and of global interest for better understanding climate change. This short film presents an overview of permafrost on Earth and focuses on the International Polar Year (IPY) activities of a research group from the University of Lisbon and its international partners. Video narration in Portuguese with English subtitles.
