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.
Article from the Patriot Ledger (Quincy, MA) introducing the Southern Ocean Diatoms PolarTREC expedition. The article focuses on a presentation for North Quincy High School students by Dr. Bethany Jenkins. Jenkins, as well as graduates students from the University of Rhode Island spoke to students about diatoms, life on the R/V Nathaniel B. Palmer and specific tools and techniques related
This one hour webinar is hosted by Dominique Richardson and the team studying the Antarctic Ice Stream Dynamics was a special event to celebrate Earth Day 2015.
This article describes the work of a team of scientists using the latest in satellite tag technology to track the movements of the Weddell seal over the Antarctic winter. The project hopes to learn more about the animals as well as the ocean environment in which they swim.
Excellent interview and accompanying video about studies of Weddell seals in Antarctic. UC Santa Cruz marine biologist Dan Costa travels to Antarctica to study the winter foraging ecology of Weddell seals through the use of sophisticated satellite tags and physical examinations. Video footage and an interview with participants has been included here.
The Memphis Flyer features Alex Eilers, manager of education for the Pink Palace Museum, who traveled more than 8,000 miles away from home to take part in a PolarTREC expedition studying Weddell Seals in the Ross Sea. While on her expedition, Ms. Eilers retrieved data from the seals and relayed the information back to students and others via her online
"The seal will capture all sorts of data: the temperature, the salinity of the water, how deep the seals dive and the pressure of the water and return that information via satellite and through this tag."
Read about Alex Eilers expedition to Antarctica to tag Weddell seals. It's hoped that information collected through tagging of seals will lead to a
