Occurrence and distribution of contaminants in bottom sediment and water of the Barron River Canal, Big Cypress National Preserve, Florida
Ronald L. Miller, Benjamin F. McPherson
2001, Florida Scientist (64) 1-19
Trace elements and organic contaminants in bottom-sediment samples collected from 10 sites on the Barron River Canal and from one site on the Turner River in October 1998 had patterns of distribution that indicated different sources. At some sites on the Barron River Canal, lead, copper, and zinc, normalized to...

Digitization and cartographic processing of 5 Lunar Orbiter (LO) IV frames (109H, 110H, 114H, 115H, and 114M) are now complete, and these data are available online at http://wwwflag.wr.usgs.gov/USGSFlag/Space/LunarOrbiter/lunorbWebtop.html. Coverage ofthese data extends from Eratosthenes crater on the west to Mare Serenitatis in the east, and from Aristoteles crater in the...
Validation of the USGS sensor model for topographic mapping of Venus using Magellan radar stereoimagery
Elpitha Howington-Kraus, Randolph L. Kirk, Donna M. Galuszka, Trent M. Hare, Bonnie L. Redding
2001, Conference Paper, Planetary Mapping: ISPRS Working Group IV/9 Workshop Proceedings
The Magellan spacecraft went into Venus orbit in 1990 and by 1992 had made three complete cycles of polar orbits, each cycle covering the full range of longitudes. During this time the spacecraft obtained synthetic aperture radar (SAR) images of >96% of the planet at a resolution of 75 m/pixel....
High resolution digital elevation models of Mars from MOC Narrow Angle stereoimages
Randolph L. Kirk, Elpitha Howington-Kraus, Brent A. Archinal
2001, Conference Paper, Planetary Mapping: ISPRS Working Group IV/9 Workshop Proceedings
In this abstract we report on our initial experiences performing stereotopographic mapping of Mars with high-resolution images from the Mars Global Surveyor Mars Orbiter Camera Narrow-Angle subsystem (MGS MOC-NA; [1]). Accurate topographic information, and, in particular, high-resolution digital elevation models (DEMs) are of intense interest at all phases of Mars...
Combining lunar photogrammetric topographic data with Clementine LIDAR data
Mark R. Rosiek, Randolph L. Kirk, Elpitha Howington-Kraus
2001, Conference Paper, Planetary Mapping: ISPRS Working Group IV/9 Workshop Proceedings
During the Clementine Mission both oblique and vertical multispectral images were collected. The oblique and vertical images from a single spectral band collected during the same orbit form a stereo pair that can be used to derive the topography. These stereo pairs were used to derive the topography of an...
Landsat 7 on-orbit modulation transfer function estimation
James C. Storey
2001, Conference Paper, Proc. SPIE 4540, sensors, systems, and next-generation satellites V
The Landsat 7 spacecraft and its Enhanced Thematic Mapper Plus (ETM+) were launched on April 15, 1999. Pre-launch modeling of the ETM+ optical system predicted that modulation transfer function (MTF) performance would change on-orbit. A method was developed to monitor the along-scan MTF performance of the ETM+ sensor system using...
Optical designs for the Mars '03 rover cameras

2001, Conference Paper, Proceedings of SPIE 4441: Current Developments in Lens Design and Optical Engineering II
In 2003, NASA is planning to send two robotic rover vehicles to explore the surface of Mars. The spacecraft will land on airbags in different, carefully chosen locations. The search for evidence indicating conditions favorable for past or present life will be a high priority. Each rover will carry...

Interglacial theme and variations: 500 k.y. of orbital forcing and associated responses from the terrestrial and marine biosphere, U.S. Pacific Northwest
Mitchell Lyle, Linda Heusser, Timothy Herbert, Alan Mix, John A. Barron
2001, Geology (29) 1115-1118
Sediments collected off northern California by Ocean Drilling Program Leg 167 contain time series that show strong, orbitally driven insolation forcing of surface oceanographic conditions. Orbital forcing caused a strong response in the distribution of major terrestrial vegetation but a less predictable response for primary productivity offshore. Terrestrial vegetation responded...
Watershed delineation using the National Elevation Dataset and semiautomated techniques
Jay R. Kost, Glenn G. Kelly
2001, Conference Paper
Federal, State, and local agencies have realized that currently available hydrologic units are not of sufficient scale for many applications. An interagency effort is under way to subdivide hydrologic units into smaller units called watersheds and subwatersheds. The National Elevation Dataset contains the best available elevation data merged into a...
Hydrogeology of the Tully Lakes area in southern Onondaga and northern Cortland Counties, New York
William M. Kappel, Todd S. Miller, Kari K. Hetcher
2001, Water-Resources Investigations Report 2001-4166
Water levels in a series of kettlehole lakes and ponds known as the Tully Lakes respond to seasonal water-level changes in the surrounding aquifer but often differ from ground-water levels in the aquifer because the lakebed sediments are poorly permeable and inhibit the exchange of water. Three sets of ground-water-level...

Development of a national seamless database of topography and hydrologic derivatives
Sandra K. Franken, Dean J. Tyler, Kristine L. Verdin
2001, Conference Paper
The recent completion of the National Elevation Dataset (NED) and the National Hydrography Dataset (NHD) has provided an avenue for nationwide development of topographically derived hydrologic data layers at a scale of 1:24,000. This multilayer dataset of hydrologic derivatives, entitled the Elevation Derivatives for National Applications (EDNA), is being developed...

Role of environmental variability in evaluating stressor effects
Samuel N. Luoma
2001, Book chapter, Ecological variability: Separating natural from anthropogenic causes of ecosystem impairment
In this chapter, we discuss how environmental variability affects the exposure of organisms and ecological systems to stressors, and give guidance on how to understand influences of stressors. We consider the characteristics of environmental variability and issues relating to the measurement of environmental variation. We discuss how to select the...
Sedimentology of the Pennsylvanian and Permian Strathearn Formation, Northern Carlin Trend, Nevada; with a section on microfossil controls on age of the Strathearn Formation
Vladimir I. Berger, Donald A. Singer, Ted G. Theodore, Anita G. Harris, Calvin H. Stevens
2001, Open-File Report 2001-402
Two framework-supported, poorly bedded conglomerate units of the middle Upper Pennsylvanian and middle Lower Permian Strathearn Formation belonging to the overlap assemblage of the Antler orogen are prominent in the northern Carlin trend. These horizons stratigraphically and temporally bracket thrust emplacement of a major allochthonous thrust plate of mainly quartzarenite...

The Cretaceous-Tertiary boundary interval in Badlands National Park, South Dakota
Philip W. Stoffer, Paula Messina, John A. Chamberlain Jr., Dennis O. Terry Jr.
2001, Open-File Report 2001-56
A marine K-T boundary interval has been identified throughout the Badlands National Park region of South Dakota. Data from marine sediments suggest that deposits from two asteroid impacts (one close, one far away) may be preserved in the Badlands. These impact-generated deposits may represent late Maestrichtian events or possibly the...
