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
Abstract
Science, Technology, Engineering, and Math (STEM) disciplines have become key focus areas in the education community of the United States. Newly adopted across the nation, Next Generation Science Standards require that educators embrace innovative approaches to teaching. Transforming classrooms to actively engage students through a combination of knowledge and practice develops conceptual understanding and application skills. The partnerships between
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
Have you ever wondered how polar scientists do it? How do they really know if the planet is losing vast quantities of ice anyway? You can use pictures from satellites to monitor the surface from year to year, but the vast majority of ice is hidden from view, buried beneath the surface in some of the most inhospitable and
In this one hour webinar PolarTREC teacher Tim Spuck explains his work with the NASA IceBridge Project, the largest airborne survey of Earth's polar ice ever conducted.
