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
PolarTREC alumni Alex Eilers created this mini-exhibit about Antarctica for the Pink Palace Museum in Memphis, Tennessee. The exhibit highlights a variety of topics as well as Ms. Eilers personal experiences in Antarctica. Topics explored include: dressing for the cold Antarctic climate, research on the Weddell seal, the history of human exploration in Antarctica, and extreme facts about the coldest
In this lesson, students will play a fun board game that teaches about the sources and types of some air pollutants, and how they affect the health of both people and the environment. Students will learn that not all pollutants are greenhouse gases. This game can be a lead-in for a discussion about climate change and what people can
This presentation features pictures, stories, data, websites and background information that complement the 2013 Bowhead Whale Calendar. The calendar contains stunning photographs and information from both traditional knowledge and contemporary research about the natural history of the bowhead whale.
This presentation, given by Robert Suydam, at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska, is an overview of the resilience of the people of the North Slope with respect to their whaling history. The presentation showcases the history of both the science and traditional knowledge used in attempting to track whale population health and the ways in which
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.
