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

AM Quincy television interview with Quincy Access Television broadcast anchor Joe Catalano. This interview is a follow-up to the August 8th interview on the Currently in Quincy program. PolarTREC teacher Cara Pekarcik discusses her upcoming expedition and plans for community outreach.
At Summit Station, Greenland, science technicians measure the snow conditions of the runway to determine if the LC-130 aircraft which brings supplies and people in and out of Summit can land and takeoff safely.
Students can use data taken by technicians at Summit Station, Greenland and develop a model to determine if snowpack conditions on the runway are sufficient

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.
North Greenland Eemian Ice Drilling website. The North Greenland Eemian Ice Drilling - NEEM - is an international ice core research project aimed at retrieving an ice core from North-West Greenland (camp position 77.45°N 51.06°W) reaching back through the previous interglacial, the Eemian.
