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
In this lesson students will learn how to use photography to support scientific research by documenting collected measurement information through observational photography. This lesson was written for a Photography course, to be taught in a lab with access to either a darkroom or computers/printers. Alternatively this lesson could be modified to work in a non-photography class, by removing the photography
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
The seismic equipment that is being used for TAMNNET (studying the Transantarctic Mountains) was specially engineered for use in polar climates. Polar projects commonly require a level of support that is several times that of seismic experiments in less demanding environments inclusive of very remote deployments. This site offers great engineering insights, design drawings, and additional related links.
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
Rachel Potter presents her research on the use of radar to measure surface currents in the top 2 m of the water column in the Chukchi Sea. The information gained from her research allows her to determine where water is going and how fast it is flowing, which can aid in issues of search and rescue, contaminant spills, marine navigation
The attached PowerPoint is an introduction to thermal stratification and turnover in lakes, and interpretation of temperature profile data. The stand-alone presentation can be used to complement a lesson in Earth Science.
