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

AM Quincy television interview with Quincy Access Television broadcast anchor Joe Catalano. This interview is a follow-up to the August 8th interview on the Currently in Quincy program. PolarTREC teacher Cara Pekarcik discusses her upcoming expedition and plans for community outreach.
There is so much media hype and public misunderstanding regarding the issue of climate change that advanced students need to be equipped to sort through the information available, find data from appropriately moderated scientific data bases, and learn to support their views with good scientific evidence rather than emotion. This lesson provides the outline for giving students some preliminary
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
Dayton's News Program, Fox 45 in the Morning, talks with teacher Chantelle Rose directly from the Arctic about her oceanographic PolarTREC expedition and follow-up involvement with the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska.
Students decorate polysterene cups later to be submerged in the ocean. Subsequent activities have students consider the effects of water pressure and depth with respect to their cups.
Objective
Students will determine mass and volume of a styrofoam cup. They will calculate the density and research the depth of the Bering, Beaufort and Chukchi Seas. They will
Students chose a research project, from one of seven suggested projects, to complete in class with a partner. Upon completion they will present their information to the class.
Objectives
Students will present a scientifically accurate project on a topic related to the PolarTREC Winter Sampling expedition.
Lesson Preparation
Introduce students to the PolarTREC website. Any expedition could be selected
