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
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.
In this activity, students diagram the hydrologic cycle. Most of the concepts will already be familiar to middle and high school students, but this activity is a good way to prepare for making the far more challenging carbon cycle and energy NON-cycle diagrams.
Objective
* Students understand that the total amount of water on Earth is constant
In this activity, students diagram the flow of energy through the Earth's ecosystems. A lot of the concepts presented here are necessary in order to fully understand the greenhouse effect and global warming. This lesson is presented as an activity to do before embarking on a study of the greenhouse effect and global warming. Unlike water or carbon
