ETOPO2.jpgLooking Beneath the Sea - Land and Ocean Topography

ETOPO2 dataset, which was generated from digital data bases of seafloor and land elevations on a 2-minute latitude/longitude grid (1 minute of latitude = 1 nautical mile, or 1.15 statute mile).

(SOS90)

AgeOfSeaFloor.jpg Age of Sea Floor with Topography

This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries.

This shows the general picture, deep current s are cold, shallow ones are warmer. The circulation process takes a long time, over 1000 years.

A time-elapsed frame set of approximately 4000 high-resolution images with original artwork visualizing the evolution of the Earth's surface due to plate tectonics over the past 600 million years.

This visualization shows ocean surface currents around the world during the period from June 2005 through December 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience.

Thermohaline circulation begins in the Earth's polar regions. When ocean water in these areas gets very cold, sea ice forms. The surrounding seawater gets saltier, increases in density and sinks. Winds drive ocean currents in the upper 100 meters of the ocean's surface. However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline).
oa_saturation.pngOcean Acidification and PH

Ocean acidification is a consequence of humankind's release of carbon dioxide emissions to the atmosphere. Excess carbon dioxide enters the ocean, reacts with water, decreases ocean pH and lowers carbonate ion concentrations.
Ocean_Drain_Land_sm.jpg Ocean Draining

This dataset gradually reveals the sea floor as the ocean is "drained".

While the coldest areas remain at the poles and the warmest area remains at the Equator, many of the seasonal variations linked to the ocean are visible in this dataset generated by a NASA computer model.

In this visualization, a model created by NASA, the color variations denote speed. The lighter green areas are moving faster than the blue areas.
seawifs_new.jpg SeaWIFS

Subtle changes in ocean color signify various types and quantities of marine phytoplankton (microscopic marine plants). The oceans are shaded based on the chlorophyll (green pigment in plants) concentration as indicated on the color bar below. The lands are shaded to depict the vegetation. Green areas have abundant vegetation, yellow areas have little vegetation, and brown areas have no vegetation.
global_swf_mission.pngSeaWIFS

The image above shows SeaWiFS data as a global average over the entire 13-year record. For the oceans, the colors represent the concentration of chlorophyll and indicate where phytoplankton most often bloomed since 1998. On the land, data are depicted as a Normalized Difference Vegetation Index (NDVI), which shows the density of green vegetation. An NDVI of zero means no green plants and a high value (0.8 or 0.9) is a thick canopy of green leaves.
