This mini exhibit explores the science behind climate change and introduces current climate change research to the public. Panels cover the topics of changing climate, ocean acidification and sea level rise, giving examples of how data is collected and current research in these fields. The exhibit also provides websites for further exploring climate change impacts.
In part two of this two-part lesson students work in pairs to explore the effects of temperature on ocean stratification using a simple plastic shoebox-sized container in which they create a mini-ocean environment. Students will apply what they learn in the lab setting along with information gained in several online articles to a basic understanding of the Global Conveyor

PolarTREC expedition: Oceanographic Conditions of the Bowhead Whale Habitat. Dr. Steve Okkonen and educator Lisa Seff arrive in Prudhoe Bay where they meet up with the crew of the R/V Ukpik. They head to Barrow Alaska, deploying a mooring with oceanographic instruments along the way.
This lesson investigates the impact of melting and freezing arctic sea ice on the properties of salinity, temperature and density that contribute to the stratification of ocean waters. This lesson combines several learning approaches including a hands-on lab, a web-quest and collaboration with other students.
Objectives
1. Students will be able to explain and demonstrate how Arctic
This article and associated video describe the findings of researchers who undertook core drilling at Lake El’gygytgyn, a lake that sits today inside a basin formed by a meteorite that struck the earth 3.6 million years ago. An associated video allows us to hear the enthusiasm and details as researcher Julie Brigham-Grette describes the findings of this remarkable discovery.
Up next, Dressing for Success in the Polar Regions. It’s February 5th, 2012 and this is Lisa Seff, PolarTREC educator, speaking with you from the Westmark Hotel in Fairbanks Alaska. If there is only one piece of advice for adventurers headed to the Arctic and Antarctic regions it would be: Layers, layers, layers.
Today PolarTREC teachers were very excited to
The sediment in Lake El'gygytgyn, (pronounced EL-ge-GIT-gin) located in NE Siberia, holds one of the longest records of climate change anywhere in the continental Arctic. How does sediment (clay and mud) tell us something about past climate? Proxy data! By studying the microfossils of diatoms and pollen in the sediment, we can re-construct the lake environment millions of
