This one hour webinar is conducted by PolarTREC alumni Missy Holzer. She highlighted her work with the High Arctic Change expedition 2008 and bringing inquiry-based science into her classroom. This webinar is part of the C-ISE online professional development course.
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
In this activity students learn about varves, annual sediment layers found in lakes. Students will analyze authentic varve data from New England in order to correlate data from three different geographic locations .
Objective
Students will analyze authentic varve sediment data and create a graph of varve thickness. Students will use their results to make inferences about
This lesson allows students to use online mapping tools to investigate global snow cover changes. Students develop a problem statement about global snow cover and then use mapping tools to investigate their problem or question.
Objective
Students will become familiar with the data and tools used to analyze snow cover changes in order to answer questions pertaining
This Live from IPY! event was held with Missy Holzer, REU Students, and researchers Mike Retelle and Al Werner from Svalbard, Norway. Missy and the team discussed the glacier-river-lake system in Svalbard and life in the field.
