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
The following presentation was given by Dr. Patricia Yager at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska. The presentation outlines Dr. Yager's work in biological and chemical oceanography, and focuses on the feedbacks between climate change and marine ecosystems at different locations around the world.
Arctic Research Mapping Application. ARMAP is a suite of online, interactive maps and services that support Arctic science. Learn more about research projects in your region of interest or scientific discipline. Explore available data or possible collaborations. Use the online mapping tools to meet your own project's specific goals.
Summit Station, Greenland Website. The station is located atop 3200 m of ice and is nearly 400 km from the nearest point of land. Summit supports a diversity of scientific research, including year-round measurements of air-snow interactions that provide crucial knowledge for interpreting data from deep ice cores drilled both at Summit and elsewhere.
