This activity requires construction of a simple salinity tester. Students will create their own calibration scale during this experiment, and look at the change in salinity that would arise if freshwater was suddenly dumped into the ocean. Materials needed for this investigation include a DC mill ampere meter, 2 D-cell batteries and holder, bronze sheeting, #18 solid wire, salt, deionized water, and ... Full description.

This self-paced, interactive tutorial enables learners to identify and measure iceberg size from remotely-sensed satellite images. Two techniques are explored: the geometric shape method, which provides a rapid rough estimate of area; and the pixel count method, which employs special software to measure the size more accurately. This resource is part of the tutorial series, Satellite Observations ... Full description.

In this learning activity, students compare polar data from the Arctic and Antarctic, explore Earth?s albedo and its effect on arctic sea ice, and examine graphed data and scientific visualizations of remotely-sensed satellite data. Readings related to the shrinking ice cap and albedo are linked to this lesson. This is part two of a four-part activity on polar science. Extension activities examining ... Full description.

In this self-paced tutorial, learners trace the feedbacks in the Earth system that are responsible for the Arctic's sensitivity to global climate change impacts. Both graphical data sets and scientific visualizations are evaluated for evidence for decreasing sea ice cover and land ice in the Arctic. Multimedia educational resources including video clips, data portals, and vocabulary terms linked to ... Full description.

This brochure describes the Moderate Resolution Imaging Spectrometer (MODIS) instrument on NASA's Terra satellite. The first NASA Earth Observing System (EOS) satellite, Terra, was launched on December 18, 1999, carrying five remote sensors. The most comprehensive EOS sensor is MODIS which offers a unique combination of features: it detects a wide spectral range of electromagnetic energy; it takes ... Full description.
