This lesson will provide students with an opportunity to design and carry out an experiment that mimics the conditions causing accelerated ice melt along the face of the Thwaites Glacier off the southwest coast of Antarctica. Created by Sarah Slack during her expedition to Thwaites aboard the icebreaker Nathaniel B. Palmer, this activity aligns with the Science and Engineering
This lesson about the factors affecting water density in the Amundsen Sea was developed by educator Sarah Slack during her PolarTREC expedition aboard the Nathaniel B. Palmer icebreaker. Part of the science mission was to create a detailed map of the seafloor at the face of the Thwaites Glacier, which revealed a series of channels that were conducting a
This lesson incorporates techniques and experimental designs used by researchers during the Southern Ocean Diatoms PolarTREC expedition and during post-expedition laboratory analysis. This guided inquiry lesson provides students the opportunity to explore photosynthesis and primary productivity using techniques to measure chlorophyll levels.
Objectives
SWBAT:
1. Use models to predict chlorophyll levels in the global oceans
2. Identify
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
This lesson was written for the 2012 Arctic Ocean Ecosystem Workshop and was inspired by the research work conducted off the coast of Barrow, Alaska by researchers Steve Okonnen and Patricia Yager with PolarTREC teachers Lollie Garay and Chantelle Rose. Students will engage in a series of exercises to investigate seasonal change in the Arctic ecosystem based on authentic
This versatile activity was inspired by my own Antarctic voyage (Lollie Garay, Oden Expedition 07) and The Amazing Race. As my students followed the journey through the Antarctic Seas on a USGS map, I realized what a great opportunity this was for them to "see" where I was in a part of the world so foreign to us
