This video documents the process of piston coring in deep water (~3000m) over the so-called '09 Seamount, Canada Basin (N. Arctic Ocean). Filmed on the 2010 International Extended Continental Shelf Survey by PolarTREC teacher Bill Schmoker.
Piston Coring in the Eastern Canada Basin on USCGC Healy. Filmed by PolarTREC teacher Bill Schmoker on the 2010 International Extended Continental Shelf Survey.
Polar Bear on Beaufort Sea ice, seen from USCGC Healy on 2010 International Extended Continental Shelf Survey. Filmed by PolarTREC teacher Bill Schmoker.
RHI (Rigid Hull Inflatable boat) recovery on the USCGC Healy near Barrow, AK in the Beaufort Sea. Filmed on the 2010 International Extended Continental Shelf Survey by PolarTREC teacher Bill Schmoker

Humans are creative. They try to solve problems in original ways. For example, some scientists are thinking of ways to decrease the amount of greenhouse gases in the air. Other scientists are thinking of ways to limit the amount of sun that reaches Earth so that the Earth won’t get so warm. Like most ideas, there are pros (good
Textbooks say that carbon dioxide is a greenhouse gas and can make earth's climate hotter. Try this lab to see if carbon dioxide gas can really act like a greenhouse.
Objectives
Students should be able to make a hypothesis, perform an experiment, analyze data and write a conclusion based on the evidence from their experiment.
Density currents drive 3D movements within the world’s oceans that dwarf surface currents by volume. Density-driven movements due to temperature/salinity differences keep the world’s oceans well mixed & help to re-distribute heat from tropical areas towards polar areas. Resultant upwelling creates some of the world’s richest ocean ecosystems. Density movements known as turbidity currents are the world’s largest
Many students are familiar with topographic maps showing relief of land surfaces. In this lab they will produce their own bathymetric maps, the underwater equivalent. A bathymetric map shows sea floor features by contouring depths below sea level (instead of elevation above sea level as in topographic maps). Students will first probe depths in “Mystery Bay”, a box
As part of a migratory bird study conducted with my bilingual second graders in Washington, DC, the students in my elementary science class spent four weeks getting to know all about birds! We initially focused on birds that migrate from our Mid-Atlantic forests to the tropical forests of Central America (an area where many of them are from)
