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
Teacher Cara Pekarcik and researcher Dr. Bethany Jenkins discuss the science behind the expedition "Southern Ocean Diatoms" while aboard the Nathaniel B. Palmer in the Southern Ocean near Antarctica.
The long-term objective of PolarTREC teacher Lesley Urasky's expedition research in Antarctica (Glacial History in Antarctica) is to determine the rate at which glaciers have receded since the Last Glacial Maximum. This lesson is designed to give students an understanding of the Last Glacial Maximum, the climatic conditions that lead to glacial periods, and how the rate of glacial
PolarConnect event with Heidi Roop who is working with an Ice Core Drilling team on the West Antarctic Ice Sheet in Antarctica. A PDF of the slides is not available for this event.
This PolarConnect event was held on 16 December 2010 with Heidi Roop who is working with an ice core drilling team on the West Antarctic Ice Sheet. This live event was broadcast and had a live component at the AGU 2010 Fall Meeting.
This PolarConnect event was held on 14 December 2010 with Lesley Urasky, John Stone, and the rest of the research team working on the Glacial History in Antarctica expedition. The event was conducted from McMurdo Station, Antarctica.
Live from IPY! event with researcher Heidi Roop and other members of the ice coring team at WAIS Divide Camp, Antarctica. The presentation focused on project and the mechanics and science of ice coring.
