El Nino, a periodic warming of the Eastern Pacific Ocean, is among Earths most powerful phenomena. Satellite, ship, and buoy observations show the 1997-98 event as the strongest on record. Visualizing how sea-surface height, sea-surface temperature, and sea-surface winds differ from normal conditions reveals the events magnitude.

Researchers and forecasters often study sea surface temperatures for an indication of hurricane potential. Scientists say above normal Atlantic Ocean temperatures is one reason for the "above normal" hurricane forecast. Hurricanes convert heat from the tropical atmosphere and oceans to wind and waves, just as a car engine converts gasoline into motion. These animations show a year in the life of global ocean temperatures, June 2, 2002 to May 11, 2003. Green indicates the coolest water, yellow the warmest. The Advanced Microwave Scanning Radiometer (AMSR-E) on the Aqua satellite saw through the clouds to provide sea surface temperatures.

Researchers and forecasters often study sea surface temperatures for an activity predictions for 2003 in part to changing conditions in the Pacific Ocean, such as the demise of El Nino. This sequence tracks warmer-than-normal waters. By January, the warm conditions began to dissipate. Fewer than normal hurricanes generally form when El Nino is present. Researchers say the Pacific may transition to the colder-than-normal La Nina phase. Areas in red represent warmer than normal and areas in blue represent cooler than normal.

Researchers and forecasters often study sea surface temperatures for an activity predictions for 2003 in part to changing conditions in the Pacific Ocean, such as the demise of El Nino. This sequence traces the evolution of the warmer-than-normal waters associated with the weak El Nino that developed in the late fall of 2002. By January, the warm conditions began to dissipate. Fewer than normal hurricanes generally form when El Nino is present. Researchers say the Pacific may transition to the colder-than-normal La Nina phase. Areas in red represent warmer than normal and areas in blue represent cooler than normal.

The course treats the following topics: - Relevant physical oceanography - Elements of marine geology (seafloor topography, acoustical properties of sediments and rocks) - Underwater sound propagation (ray acoustics, ocean noise) - Interaction of sound with the seafloor (reflection, scattering) - Principles of sonar (beamforming) - Underwater acoustic mapping systems (single beam echo sounding, multi-beam echo sounding, sidescan sonar) - Data analysis (refraction corrections, digital terrain modelling) - Applications (hydrographic survey planning and navigation, coastal engineering) - Current and future developments.

Zooming into the east coast of the United States using a SeaWiFS image taken September 16, 1999

In this web-based, interactive story, Tutangiaq (Too-tang-geye-ack - nicknamed 2T), a Canada Goose, flies across Alaska looking for his family. As he flies, he tells children about the fascinating 49th state. Children learn how Alaska was purchased from the Russians, and other facts about the state. They can also compare the size of Alaska to other states. 2T takes a flight across the volcanic chain in Alaska and helps the students to interactively explore how scientists monitor volcanoes from satellite images in near-real time. At the coast, the bird also meets his Walrus friend who shows him how the sea ice edge has receded and gives an example of an adverse effect on marine life. Finally, 2T arrives in Fairbanks where children use satellite imagery to help 2T find and unite with his family.

This lesson is designed to help students gain knowledge in accessing current weather data and in using the MY NASA DATA Live Access Server (LAS) to specify and download historical satellite data.

This Flash animation illustrates wave motion, or the movement of energy through water. Users can stop, play, fast forward and rewind the animation at any time. This visualization is one of several animations in a series developed as a component of Exploring Earth, a website that supports the textbook Earth Science.

The motion of water vapor in the Earths atmosphere collected from the GOES series of Earth-observing satellites.

Aqua, Latin for water, is a NASA Earth Science satellite mission named for the large amount of information that the mission is collecting about the Earth's water cycle, including evaporation from the oceans, water vapor in the atmosphere, clouds, precipitation, soil moisture, sea ice, land ice, and snow cover on the land and ice. Additional variables also measured by Aqua include radiative energy fluxes, aerosols, vegetation cover on the land, phytoplankton and dissolved organic matter in the oceans, and air, land, and water temperatures. This brochure provides a comprehensive overview of the Aqua spacecraft, instruments, science, and data products.

AMSR-E is a passive microwave radiometer, all the channels are in microwave spectrum, not in visible spectrum. The image is to express the water planet by simple color composite. Three day average data. Using only the descending paths, nightside orbits.
