NASA's Operation IceBridge images Earth's polar ice in unprecedented detail to better understand processes that connect the Polar Regions with the global climate system. IceBridge uses a specialized fleet of aircraft and the most sophisticated suite of science instruments ever assembled to gather data on sea ice, glaciers, and ice sheets. The data gathered today will allow future scientists

It's All About Repetition!
In this lesson, we will learn what repeat photography is, and discuss how it can be used in scientific analysis.
Introduction
What is repeat photography? It is the taking of photographs from the same location, over time, to document changes. This tool has become extremely useful in science, as a qualitative way to
This lesson was written for the 2012 Arctic Ocean Ecosystem Workshop and was inspired by the research work conducted off the coast of Barrow, Alaska by researchers Steve Okonnen and Patricia Yager with PolarTREC teachers Lollie Garay and Chantelle Rose. Students will engage in a series of exercises to investigate seasonal change in the Arctic ecosystem based on authentic
This lesson gives students of a variety of ages a cross-curricular look at the scientific wonders of Antarctica with a specific focus on Weddell Seals.
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
The long-term objective of PolarTREC teacher Lesley Urasky's expedition research in Antarctica (Glacial History in Antarctica) is to determine the rate at which glaciers have receded since the Last Glacial Maximum. This lesson is designed to give students an understanding of the Last Glacial Maximum, the climatic conditions that lead to glacial periods, and how the rate of glacial
There is so much media hype and public misunderstanding regarding the issue of climate change that advanced students need to be equipped to sort through the information available, find data from appropriately moderated scientific data bases, and learn to support their views with good scientific evidence rather than emotion. This lesson provides the outline for giving students some preliminary
How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by
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
