TEK TALKS is a series of webinars that was developed to foster understanding among scientists in regard to working with Indigenous People. View archived lectures and/or sign up for future lectures through the website.
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
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 scientific article, focuses on one of the largest pools of global carbon that is, the organic C stored in permafrost (perennially frozen) ground, and on the vulnerability to change under an increasingly warmer climate.
A scientific report describing the results of the CiPEHR Experiment as of 2011. This report attempts to answer these questions:
(1) Does ecosystem warming cause a net release of C from the ecosystem to the atmosphere?,
(2) Does the decomposition of old C that comprises the bulk of the soil C pool influence ecosystem C loss?, and
(3) How do
The Geophysical Institute Permafrost Laboratory (GIPL)
The Permafrost Laboratory deals with scientific questions related to the circumpolar permafrost dynamics and feedbacks between permafrost and global change. At the Permafrost Laboratory, data related to the thermal and structural state of circumpolar permafrost is collected and analyzed. The focus of our research is the development of methods to physically and mathematically model
Dr. Jacqueline Grebmeier presents her research on recent changes in the biology of the Pacific arctic ecosystem at the 2012 Arctic Ocean Ecosystem Workshop.
