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
Newspaper article related to outreach at the Mystic Aquarium Women in Science Day. URI researchers and PolarTREC teacher Cara Pekarcik were interviewed about their upcoming research trip to Antarctica.
Quincy Access Television interview: PolarTREC teacher Cara Pekarcik talks with Joe Catalano on the Currently in Quincy Program. The conversation includes descriptions of the PolarTREC program, a description of the research project and day-to-day activities as well as a discussion about student and community outreach.
Article from the Patriot Ledger (Quincy, MA) introducing the Southern Ocean Diatoms PolarTREC expedition. The article focuses on a presentation for North Quincy High School students by Dr. Bethany Jenkins. Jenkins, as well as graduates students from the University of Rhode Island spoke to students about diatoms, life on the R/V Nathaniel B. Palmer and specific tools and techniques related
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 is part of the Polaris Project 2012, conducted by Max Holmes and John Schade. In this session Andy Bunn, professor at Western Washington University, presents a lecture on the history and science of climate change.
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.
In this activity, students diagram the hydrologic cycle. Most of the concepts will already be familiar to middle and high school students, but this activity is a good way to prepare for making the far more challenging carbon cycle and energy NON-cycle diagrams.
Objective
* Students understand that the total amount of water on Earth is constant
In this activity, students diagram the flow of energy through the Earth's ecosystems. A lot of the concepts presented here are necessary in order to fully understand the greenhouse effect and global warming. This lesson is presented as an activity to do before embarking on a study of the greenhouse effect and global warming. Unlike water or carbon
