The map and narrative presented here explain how "low-tech" methods of scientific observation can be used to discern ocean current patterns. 60,000 Nike shoes lost overboard from a storm-tossed cargo ship in the northeastern Pacific in May 1990 began to wash ashore at times and places that coincided with the known surface current in the North Pacific Ocean, which moves in a large slow circle called ...

This site explains how core samples are taken from the ocean floor. Topics include how research cruises are planned, who makes up the crew of a research vessel, and what a cruise track is. Links to additional information are embedded in the text. Full description.

This site Presents a MODIS (Moderate-resolution Imaging Spectroradiometer) image of the Gulf Stream. The image is color-coded to show the variation in temperature of the ocean water. A brief description of the Gulf Stream, its direction and speed, and a link to other related imagery are included. Full description.

This resource offers access to a variety of materials, including general information about COOL, a photo gallery, press releases, talks and papers, and research projects. There are links to archived and real-time ocean data (sea surface temperature, surface currents and waves, autonomous glider data), and an "underwater weather forecast". Full description.

This is part of the National Oceanic and Atmospheric Administration's National Data Buoy Center website. It features text descriptions, graphs, and graphic illustrations to describe the development of land and sea breezes because of the unequal heating rates of land and water. Full description.

This site offers links to maps, posters, globes, and CD-ROMS showing seafloor topography, gravity anomalies, and bathymetry. The images were derived from GEOSAT and ERS satellite data and bathymetric surveys performed by the U.S. Navy. Full description.

This animation illustrates how tsunamis can be caused by underwater earthquakes, which are frequently located at subduction zones where oceanic plates are slipping under continental plates. Full description.

This resource uses text, images, maps and a laboratory exercise to explain how differences in the temperature and salinity of ocean water cause the formation of deep-ocean currents. It is part of the Jet Propulsion Laboratory's "Ocean Surface Topography from Space" website. This material is also available on the "Visit to An Ocean Planet" CD-ROM. Full description.

This kids page offers printable drawings to color, games, and puzzles. While performing these activities, students will learn about the TOPEX/Poseidon satellite and its mission to study the oceans. Full description.

Users can view imagery and read about tropical Pacific near-surface currents. The analysis is based on satellite altimeter- and scatterometer-derived sea level wind data. Materials presented here include monthly surface current maps, beginning with October 1992 and ending with the latest available satellite data (usually about one month delay). Links to related sites, a publications list, and a presentations ... Full description.
