Hurricane Frederic tidal floods of September 12-13, 1979, along the Gulf Coast, Orange Beach quadrangle, Alabama

Shown on the Orange Beach topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the shores of Wolf Bay, Perdido Bay, and Bayou St. John and adjacent areas in the vicinity of Orange Beach, Ala., and along the beaches exposed to the Gulf of Mexico, from Romar Beach, Ala., eastward to Perdido Key, in Florida. Damage from wind and tidal waves was widespread. The greatest damage occurred along Perdido Key in Alabama and Florida where many homes were destroyed and the highway was washed out in several places. Storm-tide frequency and records of annual maximum tides at Mobile, Ala., since 1772, are presented. Offshore winds reached about 160 miles per hour. A wind velocity of about 145 miles per hour was recorded near Dauphin Island, Ala.

Hurricane Frederic tidal floods of September 12-13, 1979, along the Gulf Coast, Lillian quadrangle, Alabama

Shown on a topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the Perdido River and Perdido Bay in the vicinity of the Alabama-Florida State line. Most of the damage in this area was due to minor flooding and high winds. Storm-tide frequency and records of annual maximum tides at Mobile, Alabama, since 1772, are presented. Offshore winds reached about 160 miles per hour. A wind-velocity of about 145 miles per hour was recorded near Dauphin Island, Alabama. (USGS)

Hurricane Frederic tidal floods of September 12-13, 1979, along the Gulf Coast, Perdido Bay quadrangle, Florida

Shown on a topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the southern shore of Perdido Bay, Ono Island in Old River, and Perdido Key exposed to the Gulf of Mexico. The most severe damage occurred along Perdido Key in Alabama and Florida where many homes were demolished and the highway was washed out in several places. Storm-tide frequency and records of annual maximum tides at Mobile, Alabama, since 1772, are presented. Offshore winds reached about 160 miles per hour. A wind-velocity of about 145 miles per hour was recorded near Dauphin Island, Alabama. (USGS)

Hurricane Frederic tidal floods of September 12-13, 1979, along the Gulf Coast, West Pensacola quadrangle, Florida

Shown on the West Pensacola topographic map are floodmarks elevations left by Hurricane Frederic tides of September 12-13, 1979, along the eastern shore of Perdido Bay in the vicinity of West Pensacola, Florida. Most of the damage in this area was due to minor flooding and high winds. Still water elevations ranged from about 5 feet above National Geodetic Vertical Datum in the sheltered areas to about 7.5 feet in areas subject to wind setup. Storm-tide frequency and records of annual maximum tides at Mobile, Alabama, since 1772, are presented. Offshore winds reached about 160 miles per hour. A wind-velocity of about 145 miles per hour was recorded near Dauphin Island, Alabama. (USGS)

Hurricane Frederic tidal floods of September 12-13, 1979, along the Gulf Coast, Oriole Beach, Garcon Point, Holley, South of Holley and Navarre quadrangles, Florida

Shown on the Oriole Beach-Garcon Point-Holley-South of Holley-Navarre, Fla., topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the shores of Santa Rosa Sound and the Gulf of Mexico from Pensacola Beach eastward to the Narrows near Fort Walton Beach, Fla. Storm-tide frequency and records of annual maximum tides at Mobile, Ala., since 1772, are presented. Offshore winds reached about 160 miles per hour. A wind-velocity of about 145 miles per hour was recorded near Dauphin Island, Ala.

Coastal-change and glaciological map of the Eights Coast area, Antarctica, 1972-2001

Changes in the area and volume of polar ice sheets are intricately linked to changes in global climate, and the resulting changes in sea level may severely impact the densely populated coastal regions on Earth. Melting of the West Antarctic part alone of the Antarctic ice sheet could cause a sea-level rise of approximately 6 meters (m). The potential sea-level rise after melting of the entire Antarctic ice sheet is estimated to be 65 m (Lythe and others, 2001) to 73 m (Williams and Hall, 1993). In spite of its importance, the mass balance (the net volumetric gain or loss) of the Antarctic ice sheet is poorly known; it is not known for certain whether the ice sheet is growing or shrinking. In a review paper, Rignot and Thomas (2002) concluded that the West Antarctic part of the Antarctic ice sheet is probably becoming thinner overall; although the western part is thickening, the northern part is thinning. Joughin and Tulaczyk (2002), based on analysis of ice-flow velocities derived from synthetic aperture radar, concluded that most of the Ross ice streams (ice streams on the east side of the Ross Ice Shelf) have a positive mass balance. The mass balance of the East Antarctic is unknown, but thought to be in near equilibrium. Measurement of changes in area and mass balance of the Antarctic ice sheet was given a very high priority in recommendations by the Polar Research Board of the National Research Council (1986), in subsequent recommendations by the Scientific Committee on Antarctic Research (SCAR) (1989, 1993), and by the National Science Foundation's (1990) Division of Polar Programs. On the basis of these recommendations, the U.S. Geological Survey (USGS) decided that the archive of early 1970s Landsat 1, 2, and 3 Multispectral Scanner (MSS) images of Antarctica and the subsequent repeat coverage made possible with Landsat and other satellite images provided an excellent means of documenting changes in the coastline of Antarctica (Ferrigno and Gould, 1987). The availability of this information provided the impetus for carrying out a comprehensive analysis of the glaciological features of the coastal regions and changes in ice fronts of Antarctica (Swithinbank, 1988; Williams and Ferrigno, 1988). The project was later modified to include Landsat 4 and 5 MSS and Thematic Mapper (TM) (and in some areas Landsat 7 Enhanced Thematic Mapper Plus (ETM+)), RADARSAT images, and other data where available, to compare changes over a 20- to 25- or 30-year time interval (or longer where data were available, as in the Antarctic Peninsula). The results of the analysis are being used to produce a digital database and a series of USGS Geologic Investigations Series Maps consisting of 24 maps at 1:1,000,000 scale and 1 map at 1:5,000,000 scale, in both paper and digital format (Williams and others, 1995; Williams and Ferrigno, 1998; and Ferrigno and others, 2002).

Coastal-change and glaciological map of the Bakutis Coast, Antarctica: 1972-2002

Changes in the area and volume of the polar ice sheets are intricately linked to changes in global climate, and the resulting changes in sea level may severely impact the densely populated coastal regions on Earth. Loss of the West Antarctic part of the Antarctic ice sheet alone could cause a sea-level rise of approximately 6 m. The potential sea-level rise after melting of the entire Antarctic ice sheet is estimated to be 65 m to 73 m. In spite of its importance, the mass balance (the net volumetric gain or loss) of the Antarctic ice sheet is poorly known; it is not known whether the ice sheet is growing or shrinking. As a result, measurement of changes in the Antarctic ice sheet was given a very high priority in recommendations by the Polar Research Board of the National Research Council (1986), by the Scientific Committee on Antarctic Research (SCAR) (1989), and by the National Science Foundation's (1990) Division of Polar Programs. An archive of early 1970's Landsat 1, 2, and 3 Multispectral Scanner (MSS) images of Antarctica and the fact that the repeat coverage with satellite images provided an excellent means of documenting changes in the coastline of Antarctica provided the impetus for carrying out a comprehensive analysis of the glaciological features of the coastal regions and changes in ice fronts of Antarctica. The project was later modified to include Landsat 4 and 5 MSS and Thematic Mapper (TM) and RADARSAT images to compare changes over a 20- to 25- year time interval and to prepare a series of 24 1:1,000,000-scale and 1 1:5,000,000-scale U.S. Geological Survey Geologic Investigations Series Maps ('I-Maps') (Williams and others, 1995; Williams and Ferrigno, 1998; and Ferrigno and others, 2002) in both paper and digital format.
