The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).The file is georeferenced to earth's surface using the State Plane projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.

The Oregon Department of Geology and Mineral Industries (DOGAMI) contracted with Watershed Sciences, Inc. to collect high resolution topographic LiDAR data for multiple areas within the State of Oregon. The areas for LiDAR collection have been designed as part of a collaborative effort of state, federal, and local agencies in order to meet a wide range of project goals. This LiDAR data set was collected August 23, 24, 31, Sept 2 - 5, 2010 and falls mainly in Klamath County, and very small portions of Douglas and Jackson counties in Oregon. This data set consists of bare earth and unclassified points. The average pulse density is 8.39 pulses per square meter over terrestrial surfaces. The area of interest (AOI) totals 283 square miles (181,081 acres) and the total area flown (TAF) covers 308 square miles (197,011 acres). The TAF acreage is greater than the original AOI acreage due to buffering and flight planning optimization. In some areas of heavy vegetation or forest cover, there may be relatively few ground points in the LiDAR data. Elevation values for open water surfaces are not valid elevation values because few LiDAR points are returned from water surfaces. LiDAR intensity values were also collected.

There have been many earthquake occurrences in Southern California. This set of slides shows earthquake damage from the following events: Imperial Valley, 1979, Westmorland, 1981, Palm Springs, 1986; and Whittier, 1987. These events were all earthquakes with a magnitude of 5.9 or higher with damage estimates of one million dollars or more. Imperial Valley Earthquake of October 15, 1979. Epicenter 32.6 N, 115.3 W; depth: 7 km; magnitude 6.8; damage: $30 million; no deaths. The earthquake was felt over approx. 128,000 sq km. The worst damage occurred in southern Imperial County and northeastern Baja California where eleven businesses and two homes were destroyed. Four hundred forty businesses and 1565 homes were damaged. Although there were no deaths, ninety-one people were reported injured mainly by flying glass or by falling objects. The greatest single structural loss was to the Imperial County Services Building in El Centro. Non-structural damage included damage to bridge abutments that were cracked and roadbeds that shifted due to slumping or faulting. The agriculture industry incurred damage to canals and irrigation ditches, damage to subsurface drain tiles which were disturbed by the movement along the Imperial Fault. The worst damage incurred by the agriculture industry wasto the All-American Canal which brings Colorado River water into the Imperial Valley. Ground shaking caused the collapse of levees on both sides of the canal along a 13-km stretch of the canal east of Calexico. Extensive lateral slope failure occurred along this and other canals. In some places canal banks settled by more than 1 m. Westmorland Earthquake of April 26, 1981. Epicenter 33.1 N, 115.6 W; depth: 4 km; magnitude 6.3 ML(B); damage: $1-3 million; no deaths. Twelve buildings in Westmorland were severely damaged, ten beyond repair, and an additional 30 sustained minor damage. Seventy percent of the town's 900 homes (many of which were built of adobe and brick) were damaged, and five homes were condemned. Six mobile homes were knocked off their foundations and nine homes sustained minor damage to foundations, porches, and walls. Electrical service was interrupted for onehour and the water supply was interrupted for 10 hours. The sewage plant sustained an estimated $40,000 damage. Total damage was estimated at $1.5 million. Subsidence was reported on several rural roads in the area. Liquefaction caused scores of "mudpots," and oozing soil in nearby fields. One country road west of Westmorland collapsed, producing a 2-footdrop-off. In rural areas $100,000 in damages was incurred when unreinforced, concrete-lined irrigation canals were broken. Palm Springs Earthquake of July 8, 1986. Epicenter 34.0 N, 116.6 W; depth: 10 km; magitude 6.0; damage: $4.5 million; no deaths. At least 29 people were injured and some damage occurred in the Palm Springs-Morongo Valley area. Landslides ccurred in the area. The quake caused serious damage at the Devers substation of Southern California Edison Company. Some residences in the Whitewater Canyon area were badly damaged. Damage from this quake was approximately $4.5 million. Minor damage occurred at Angelus Oaks, Desert Hot Springs, North Palm Springs, Palm Desert, Palm Springs, and Yucca Valley. The quake was felt throughout much of southern California and in Las Vegas, Nevada, Lake Havasu City, Arizona and in the northern Baja California area of the United States and Mexico. Whittier Narrows Earthquake of October 1, 1987. Epicenter 34.0 N, 118.1 W; depth: 11 km; magnitude 5.9; damage: $358 million; 8 deaths. At 7:42 A. M (Pacific Daylight Time), on October 1, 1987, a fault located about 11 km below the surface and 20 km east of downtown Los Angeles, California, began to rupture. The fault was an extension of the previously identified Whittier fault. The resulting earthquake caused about $358 million in property damage and the loss of 8 lives. Severe damage was confined mainly to communities east of Los Angeles and near the epicenter. No severe structural damage to high-rise structures in downtown Los Angeles was reported. Non-structural damage did occur, however. In Whittier the most severe damage occurred in the "Uptown" business district. Similar damage was observed in the old downtown section of Alhambra and in the "Old Town" section of Pasadena. These areas had high concentrations of unreinforced masonry buildings. Residences which sustained damage usually were constructed of masonry, were not fully anchored to foundations, or were houses built over garages with large door openings. Many chimneys collapsed and in some cases, fell through roofs. Wood frame residences sustained relatively little damage. Damage often occurred around large windows. Light fixtures and suspended ceilings fell in many buildings within a 10-km radius of the epicenter. A student at California State University, Los Angeles was killed when the connectors for a precast concrete fascia panel failed and the panel fell two stories crushing her. Damage was incurred on a bridge at the interchange of I-605 and I-5, where the columns in the center were severely damaged.

The eggs, larvae, and juveniles of horseshoe crabs L. polyphemus contribute significantly to the forage base of many species in Delaware Bay. The eggs also provide a crucial forage base for at least 11 species of shorebird. Birds foraging on L. polyphemus eggs significantly contribute to the wildlifewatching industry in Delaware and New Jersey. L. polyphemus also has significant economic importance to the bait fishery and the pharmaceutical industry. Estimates suggest the population of L. polyphemus in Delaware Bay have declined. Disease, harvest for bait, and habitat loss may contribute to the apparent population decline. However, environmental contamination also may play a role. This investigation looked at potential adverse effects to L. polyphemus by the endocrine disrupting pesticide methoprene. Methoprene is an insect growth regulator that acts as a juvenile hormone mimic. Land managers apply methoprene aerially to marshes of Delaware Bay to control mosquitoes. This investigation hypothesized that mosquitoes and L. polyphemus will experience similar adverse effects from a compound like methoprene. Two procedures were used to assess these effects. First, any macroscopic developmental abnormalities were recorded by observing egg and larval development in vitro. Second, a proteomics approach was used to address the multitude of potential pathways that may become altered as a result of methoprene exposure. The proteomics approach involved three phases: 1 separation and visualization of unknown proteins that are expressed differently in controls as compared to treated eggs, embryos, and potentially larvae; 2 visualization of those proteins that are consistently over or underexpressed in treated individuals compared to controls; and 3 identification of these proteins by de novo amino acid sequencing. A total of 55 female and 22 male adult crabs were collected from Kimbles Beach at Cape May National Wildlife Refuge for two separate spawns. Phase I of the investigation examined embryo, larval, and juvenile response to a series of exposures to methoprene solutions at 0 gl, 1 g, 10 gl, and 100 gl using pore water from Kimbles Beach and artificial sea water. Eggs, embryos, larvae, and juveniles were monitored for fertilization, hatching, and survival and for any macroscopic abnormities. Eggs and larvae all treatments were periodically removed and archived in liquid nitrogen for later proteomic analysis. Phase II of the investigation involved a proteomics approach to observing whether the methoprene may have caused more subtle effects to the embryos, larvae, and juveniles. The results provided no evidence that a treatment effect occurred. We observed no obvious acute effects of environmentally relevant concentrations of the mosquito larvicide methoprene on developing L. polyphemus embryos, larvae, or first molt post hatch juveniles. Through this investigation we found evidence for a No Observed Adverse Effects Level of 100 gl for methoprene exposure. Our findings provide evidence that chemical exposure to methoprene may not be a limiting factor to the population of L. polyphemus. This information will be useful to land managers, agencies involved in mosquito control, and the numerous groups interested in finding and examining the limiting factors on the L. polyphemus population.

NOAA's National Geophysical Data Center (NGDC) is building high-resolution digital elevation models (DEMs) for select U.S. coastal regions. These integrated bathymetric-topographic DEMs are used to support tsunami forecasting and modeling efforts at the NOAA Center for Tsunami Research, Pacific Marine Environmental Laboratory (PMEL). The DEMs are part of the tsunami forecast system SIFT (Short-term Inundation Forecasting for Tsunamis) currently being developed by PMEL for the NOAA Tsunami Warning Centers, and are used in the MOST (Method of Splitting Tsunami) model developed by PMEL to simulate tsunami generation, propagation, and inundation. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources, including NGDC, the U.S. National Ocean Service (NOS), the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to the vertical tidal datum of Mean High Water (MHW) and horizontal datum of World Geodetic System 1984 (WGS84). Grid spacings for the DEMs range from 1/3 arc-second (~10 meters) to 3 arc-seconds (~90 meters).

MODIS Thermal Anomalies/Fire products are primarily derived from MODIS 4- and 11-micrometer radiances. The fire detection strategy is based on absolute detection of a fire (when the fire strength is sufficient to detect), and on detection relative to its background (to account for variability of the surface temperature and reflection by sunlight). Numerous tests are employed to reject typical false alarm sources like sun glint or an unmasked coastline. Information on each individual MODIS Platform/Product are available at: https://lpdaac.usgs.gov/lpdaac/products/modis_products_table

This project is a cooperative effort between the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment, the University of Hawaii, BAE Systems Spectral Solutions and Analytical Laboratories of Hawaii, LLC. The goal of the work was to map the coral reef habitats of American Samoa, Guam and the Common Wealth of the Northern Mariana Islands by visual interpretation and manual delineation of IKONOS satellite imagery. A two tiered habitat classification system was tested and implemented in this work. It integrates geomorphologic reef structure and biological cover into a single scheme and subsets each into detail. It also includes thirteen zones. Benthic features were mapped that covered an area of 45.2 square kilometers of which 4.4 were unconsolidated sediment and 40.9 were coral reef and hard bottom. Of the coral reef and hard bottom class, 59.9% is colonized by greater than 10% coral cover.

The 2014 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. States and equivalent entities are the primary governmental divisions of the United States. In addition to the fifty States, the Census Bureau treats the District of Columbia, Puerto Rico, and each of the Island Areas (American Samoa, the Commonwealth of the Northern Mariana Islands, Guam, and the U.S. Virgin Islands) as the statistical equivalents of States for the purpose of data presentation.

The rainfall-runoff erosivity factor (R-Factor) quantifies the effects of raindrop impacts and reflects the amount and rate of runoff associated with the rain. The R-factor is one of the parameters used by the Revised Unified Soil Loss Equation (RUSLE) to estimate annual rates of erosion. This product is a raster representation of R-Factor derived from isoerodent maps published in the Runoff Estimates for Small Rural Watersheds and Development of a Sound Design method. Volume II. (Fletcher et al., 1977). Lines connecting points of equal rainfall erosivity are called isoerodents. The isoerodents plotted on a map of Alaska were digitized, then values between these lines were obtained by linear interpolation. The final R-Factor data are in raster GeoTiff format at 800 meter resolution in Albers Conic Equal Area,WGS84, WGS84.
