Fires in British Columbia
| Title |
Fires in British Columbia |
| Description |
A large fire in western British Columbia was spilling smoke down over the glacier-covered slopes of the Coast Range Mountains on July 28, 2004. In the deeply carved valleys between the white-capped peaks, turquoise rivers thick with finely ground glacial sediment flow out to the Pacific Ocean through the narrow gap between Vancouver Island (bottom left) and mainland Canada. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this image, and the places where the sensor detected actively burning fires are outlined in red. The high-resolution image provided above is 250 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

Phytoplankton off Vancouver

| Title |
Phytoplankton off Vancouver Island |
| Description |
The bright blue and green swirls that the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) detected off the coast of Vancouver Island, Canada, were made by millions of tiny ocean plants called phytoplankton. The coastal waters of the Eastern Pacific are productive because wind and ocean currents allow nutrient-rich water from deep in the ocean to rise to the surface. The cold, rising water carries phosphates and nitrates, which act as fertilizer to the phytoplankton that grow in the sunlit waters at the ocean's surface. Since phytoplankton are the base of the food chain, areas that support large phytoplankton blooms tend to have large fish populations. Off the coast of Vancouver Island and Washington State, phytoplankton blooms tend to happen when winds blow down the coast from the north. The winds push the ocean's surface water west, out to sea. Deep water rises up to replace the wind-blown surface water, and it carries the nutrients needed to support phytoplankton blooms. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this photo-like image on June 25, 2006. The large image provided above has a spatial resolution of 250 meters per pixel. The image is available in additional resolutions from the MODIS Rapid Response Team.

Toxic Algal Bloom off Washin
…
| Title |
Toxic Algal Bloom off Washington |
| Description |
A multi-institutional, international team of researchers report that a toxic bloom of algae has appeared in the eastern Pacific, located about 24 km (15 miles) off the northwest coast of Washington. Situated in the region known as the Juan de Fuca eddy, the bloom spans a large area roughly 48 km (30 miles) across. Scientists from the National Oceanic and Atmospheric Administration (NOAA), the University of Washington, San Francisco State University, the University of Maine, the University of Western Ontario and the Institute of Ocean Sciences in Canada, and the National Marine Fisheries Science Center report finding concentrations of "pseudo-nitzschia" as high as 11 million cells per liter of sea water. Such a bloom is considered unusually intense and potentially lethal for humans. Even 200 cells per liter is considered dangerous."Pseudo-nitzschia" can release domoic acid, which has been found to accumulate in the tissue of shellfish. If ingested by humans, domoic acid will attack tissue in the brain that humans use for memory and learning. Officials in Washington are closely monitoring the situation. There is some concern that if a major storm passes through it could push the bloom eastward into near-shore waters. Harmful algal blooms have been reported with increasing numbers and intensity in recent years, typically forming just outside the Strait of Juan de Fuca. This strait links Puget Sound to the Pacific Ocean. Scientists believe this year?s bloom is being fed by nutrients upwelled from near the ocean bottom as well as nutrients swept off the land into the sea from Vancouver and Washington. The true-color images above show the region affected on September 24 and 26, 2004. The scenes were acquired by the Sea-viewing Wide Field-of-view Sensor aboard the OrbView-2 satellite. Note the greenish swirls in the water, in contrast to its usual dark blue color. It is impossible to say, using satellite imagery alone, which of the bloom shown in these images is "pseudo-nitzschia" and which is harmless phytoplankton, but such imagery can help scientists monitor current patterns and see which way the bloom may spread over time.

…
| Description |
The Zero Emissions (ZE) transit bus passes a mock-up orbiter named Explorer on a trek through the KSC Visitor Complex. Provided by dbb fuel cell engines inc. of Vancouver, Canada, the ZE bus was brought to KSC as part of the Center's Alternative Fuel Initiatives Program. The bus uses a Proton Exchange Membrane fuel cell in which hydrogen and oxygen, from atmospheric air, react to produce electricity that powers an electric motor drive system. The by-product "exhaust" from the fuel cell is water vapor, thus zero harmful emissions. A typical diesel-powered bus emits more than a ton of harmful pollutants from its exhaust every year. The ZE bus is being used on tour routes at the KSC Visitor Complex for two days to introduce the public to the concept |
