Afterirradiated fuel rods were taken from the nuclear reactors to the processing facilities at Hanford, they were exposed to a series of chemical processes designed to dissolve away the fuel rod itself, allowing workers to retrieve the plutonium. As you may imagine, the chemicals needed to dissolve away the metal of the fuel rod were powerful.At the same time, once those chemicals were exposed to the irradiated fuel rods, the chemicals needed to dissolve the metal became radioactive and extremely hot.They also couldn't be used over and over again whenever a new batch of irradiated fuel rods was delivered to the processing canyons. So, these chemicals became a waste by-product of producing plutonium and had to be disposed of. Additionally, following their use inside the processing facilities, the chemicals were caustic and extremely hazardous to humans and the environment.They couldn't be poured onto the ground or into the Columbia River. Early Hanford scientists understood that these chemical and radioactive wastes could be hazardous to people or the environment, and decided to build a series of massive underground storage tanks ranging in capacity from 55,000 gallons to more than 1,000,000 gallons to hold the wastes.Scientists believed that the tanks would only be used temporarily until a permanent place to dispose of the waste was identified.Still, they required that the early tanks be constructed with robust materials consisting of a carbon steel shell surrounded by reinforced concrete.This proved to be a fortunate decision since many of the tanks remain in use to this day.No new waste from plutonium production has been added to the tanks in many years, but some of the waste that was originally put in them is still there. After the chemicals needed for plutonium processing had been used, they were put into these storage tanks that were constructed throughout Hanford's 200 Area in a series of groups.Called " tank farms", eighteen groups of tanks, some numbering as few as two tanks and others up to sixteen, are located near the processing facilities where these kinds of liquid wastes were generated.As the irradiated fuel rods went through the processing canyons, the chemicals needed to dissolve away the fuel rods were routed from the processing facilities and into these storage tanks. 149 of these single shell tanks were built at Hanford between 1943 and 1964.83 single shell tanks are located in the 200 West Area, with another 66 single shell tanks found in the 200 East Area.However, even with 149 tanks available, thevolume of chemical wastes generated through the plutonium production mission far exceeded the capacity of the tanks.Some of the liquid waste did end up being put into holding facilities and some was poured into open trenches.Some of the wastes that were put into the tanks didn't stay there, as the heat generated by the waste and the composition of the waste caused an estimated 67 of these tanks to leak some of their contents into the ground.Some of this liquid waste migrated through the ground and has reached the groundwater. Between 1968 and 1986, Hanford engineers built another 28 tanks to be used on the Site.These tanks were sturdier, made with a second shell to surround the carbon steel and the reinforced concrete called "double shell tanks".Three double shell tanks are in the 200 West Area, with another 25 found in the 200 East Area. The materials inside waste tanks consist of liquids, gases, semi-solids, and solids.All of the liquid that can be safely pumped out of the single shell tanks and transferred into double shell tanks has taken place.Work now centers on transferring the solid and semi-solid wastes into the double shell models. Crews continue to search for new technologies which can facilitate the removal of the semi-solids and solids out of these storage tanks.This is required since the original pumps inside the tanks were designed to remove only liquid waste.What's left inside the tanks today are saltcakes, a material with the consistency of wet beach sand, and sludges.Also inside are wastes which resemble peanut butter, small broken icebergs, foam, or whitish crystals.None of these wastes are easily removed. Adding to the challenge is the fact that access to the materials inside the waste tanks is through long, typically skinny pipes extending out of the tanks.It is through these pipes that crews are forced to send machines and devices into the tanks which are designed to break up the waste or push the waste toward a pump where it can then be removed.Because the pipes weren't expected to be needed in this way, the diameter of many of the pipes is small; only about one foot wide.Scientists and engineers have had to develop and then build machines that are small enough to get through that narrow pipe, but also sturdy enough to withstand the high temperatures and caustic conditions inside the tank.It's also a requirement that the machines be powerful enough to break up the solid wastes that they encounter and strong enough to force the waste into parts of the tank where it can be pumped out.Currently, engineers are evaluating cutting a larger opening in the top of the tanks to install a more effective, robust retrieval system. As part of the agreement regulating Hanford cleanup (called the Tri-Party Agreement), crews must remove at least 99% of the material in every tank on the Site, or at least as much waste that can be removed based on available technology. The final process associated with the tank farm waste is at the Waste Treatment Plant, also known as the Vitrification Plant.Waste from tank farms throughout the site will be pumped into the mammoth Waste Treatment Plant complex where it will be treated and characterized as low activity waste or high level waste based on the waste's composition.The waste will then begin a process where glass forming materials bond with the waste in a high temperature environment.This procedure, called vitrification, locks the waste into a more stable glass form.Once the waste has been vitrified, it will be put into steel canisters and safely dispositioned.

Summary

Description

The MOPITT (Measurements Of Pollution In The Troposphere) instrument on the NASA Terra Satellite makes measurements of infrared radiation originating from the surface of the planet and isolates the energy being radiated from carbon monoxide (CO). By using appropriate data analysis techniques, concentration profiles of CO (Level-2 (L2) data) can be obtained on a global basis at a reasonably high horizontal (~22km) and vertical resolution (~3km).The MOPITT Level-3 (L3) data products provided in this data set are a subset of the daily averages from the L2 data. This subset was produced by overlaying a global 1x1-degree grid onto the L2 data, and then clipping the data to this southern Africa subset which originates at 5 degrees longitude and -35 degrees latitude and extends to 60 degrees longitude and 35 degrees latitude. Data are reported for 2 heights, 700 and 350 hPa, from daytime swaths for the period August 1-September 30, 2000, the SAFARI 2000 Dry Season Campaign.

During February 1982 and again from August 7 to October 22, 1985 the U.S. Geological Survey (USGS) conducted four cruises to cover the U.S. Gulf of Mexico Continental Margin Exclusive Economic Zone (EEZ) seaward of the continental shelf edge. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. A total of 16 digital mosaics of a 2 degree by 2 degree (or smaller) area with a 50-meter pixel resolution were completed for the Gulf of Mexico region.

Summary

Description

Habitat maps of Puerto Rico and the U.S. Virgin Islands were created by visual interpretation of aerial photographs using the Habitat Digitizer Extension. Aerial photographs are valuable tools for natural resource managers and researchers since they provide an excellent record of the location and extent of habitats. However,spatial distortions in aerial photographs due to such factors as camera angle, lens characteristics, and relief displacement must be accounted for during analysis to prevent incorrect measurements of area, distance, and other spatial parameters. These distortions of scale within an image can be removed through orthorectification. During orthorectification, digital scans of aerial photos are subjected to algorithms that eliminate each source of spatial distortion. The result is a georeferenced digital mosaic of several photographs with uniform scale throughout the mosaic. Features near land are generally georeferenced with greater accuracy while the accuracy of features away from land is generally not as good. Where no land is in the original photographic frame only kinematic GPS locations and image tie points were used to georeference the images. After the orthorectified mosaics were created, photointerpreters were able to accurately and reliably delineate boundaries of features in the imagery as they appear on the computer monitor.

Benthic habitats of the moderate-depth marine environment in and around the Virgin Islands Coral Reef National Monument were mapped using a combination of semi-automated classification and visual interpretation of acoustic imagery. The objective of this effort, conducted by NOAA's Center for Coastal Monitoring and Assessment - Biogeography Branch in partnership with the U.S. National Park Service (NPS), was to provide spatially-explicit information on the moderate-depth habitat types, biological cover and live coral cover south of St. John. The data contained in this shapefile denote the position of the drop camera as it drifted over 117 ground validation (GV) sites explored by NOAA field scientists to further refine habitat map classification. Considering vessel drift during habitat characterization, the entire evaluation period was most accurately represented by a series of GPS points logged at five-second intervals.

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

Description

The NOAA WAVEWATCH III® hindcast dataset comprises output fields from the monthly WAVEWATCH III® hindcast model runs conducted at the National Centers for Environmental Prediction. Each model run produces a collection of files containing gridded fields comprised of input and mean wave parameters such as the significant wave height, directions, frequencies etc. Once per month, a wave simulation is carried out using restart files from the previous month and forced by hindcast wind products for the entire month. The resulting output data are transferred to NODC on a monthly basis. NODC assembles the series of files into monthly accessions to facilitate archival retention and public access. The fields are encoded in the standard GRIdded Binary version 2 (GRIB2) file format. Wave spectral data summaries are included, as well as detailed spectra at selected locations, in tabular text format. Nine different sets of output fields, corresponding to nine different grids used in the numerical simulations, are included. These include a global grid, as well as regional and coastal grids covering much of the North Atlantic and North Pacific oceans.
