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.
1. Use models to predict chlorophyll levels in the global oceans
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
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
The inspiration for this lesson was to encourage students to experience and appreciate nature with their senses while addressing a Common Core State Standard. This activity allows students to infer what an object is by using all senses but sight. Phonemic awareness is a skill difficult to isolate outside of the context of reading; the audio portion of
This PowerPoint presentation, "When environmental conditions promote evolution: An introduction to morpho-physiological and behavioral differences between two phocids", was submitted as a capstone project
as part of the PolarTREC Online Course Series by participant Patricia Azinhaga. This stand-alone presentation can be used to complement a Life Science lesson.
Coring trees is a way of learning about trees without cutting them down. When a tree is cored, the rings are examined to learn about the history and growth of a tree. In this lesson students will participate in a hands-on activity to help them investigate what information can be gained by studying and comparing tree core samples collected
This video shows divers investigating microscopic life forms living under the arctic sea ice. The video accompanies a presentation given by researcher Rolf Gradinger at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska.
This presentation, given by researcher Rolf Gradinger at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska, showcases the history and exploration of the unique and hidden microscopic life found under the Arctic Seas.
This presentation, given by Matt Druckenmiller at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska presents information on both the science and local knowledge of ice conditions off the coast of Alaska. His research considers whether a reduction or change in the variability of sea ice has an effect on the feeding patterns and thus body size of the
