How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by

This is a one hour webinar specifically for the participants of the Polaris Project 2012, conducted by Max Holmes and John Schade. This is the introductory session.
Using photos from a variety of websites, including the PolarTREC and SCINI websites, students will identify organisms to phylum and/or class level (e.g. polychaetes, starfish, brittle stars, sponges) and then research the primary foods that these organisms eat. They will then develop a simple food web for these organisms.
This Live from IPY! Event was held with PolarTREC Teacher Cameo Slaybaugh and her project PI, Stacy Kim who are members of the Antarctic Undersea ROV '08 PolarTREC expedition. The team talked about the underwater ROV, SCINI, and the research they are conducting in the waters surrounding Ross Island, Antarctica.
