Textures of the soils and rocks at Gusev Crater from Spirit’s Microscopic Imager
The Microscopic Imager on the Spirit rover analyzed the textures of the soil and rocks at Gusev crater on Mars at a resolution of 100 micrometers. Weakly bound agglomerates of dust are present in the soil near the Columbia Memorial Station. Some of the brushed or abraded rock surfaces show igneous textures and evidence for alteration rinds,...Herkenhoff, Kenneth E.; Squyres, S. W.; Arvidson, R.; Bass, D.S.; Bell, J. F.

Magnetic properties experiments on the Mars Exploration Rover Spirit at Gusev Crater
The magnetic properties experiments are designed to help identify the magnetic minerals in the dust and rocks on Mars—and to determine whether liquid water was involved in the formation and alteration of these magnetic minerals. Almost all of the dust particles suspended in the martian atmosphere must contain ferrimagnetic minerals (such as...Bertelsen, P.; Goetz, W.; Madsen, M.B.; Kinch, K.M.; Hviid, S.F.; Knudsen, J.M.; Gunnlaugsson, H.P.; Merrison, J.; Nørnberg, P.; Squyres, S.

Geologic and bayhymetric reconnaissance overview of the San Pedro Shelf Region, southern California
This report presents a series of maps that describe the bathymetry and late Quaternary geology of the San Pedro shelf area as interpreted from seismic-reflection profiles and 3.5-kHz and multibeam bathymetric data. Some of the seismic-reflection profiles were collected with Uniboom and 120-kJ sparker during surveys conducted by the U.S....Wolf, Stephen C.; Gutmacher, Christina E.

Sidescan sonar imagery and surficial geologic interpretation of the sea floor off Branford, Conneticut
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Connecticut Department of Environmental Protection (CT DEP), Figure 1 - Map of Study Areahas produced detailed geologic maps of the sea floor in Long Island Sound, a major East Coast estuary surrounded by the most densely...Poppe, L.J.; Paskevich, V.F.; Moser, M.S.; DiGiacomo-Cohen, M.

Assessment of Hazards Associated with the Bluegill Landslide, South-Central Idaho
The Bluegill landslide, located in south-central Idaho, is part of a larger landslide complex that forms an area the Salmon Falls Creek drainage named Sinking Canyon Recent movement of the Bluegill landslide, apparently beginning sometime in late 1998 or early 1999, has caused a 4.5 ha area of the canyon rim to drop as much as 8 m and move...Ellis, William L.; Schuster, Robert L.; Schulz, William H.
Coastal vulnerability assessment of Fire Island National Seashore to sea-level rise
A coastal vulnerability index (CVI) was used to map the relative vulnerability of the coast to future sea-level rise within Fire Island National Seashore (FIIS), New York. The CVI ranks the following in terms of their physical contribution to sea-level rise-related coastal change: geomorphology, regional coastal slope, rate of relative sea-level...Pendleton, Elizabeth A.; Williams, S. Jeffress; Thieler, E. Robert
Coastal vulnerability assessment of Gulf Islands National Seashore (GUIS) to sea-level rise
A coastal vulnerability index (CVI) was used to map the relative vulnerability of the coast to future sea-level rise within Gulf Islands National Seashore (GUIS) in Mississippi and Florida. The CVI ranks the following in terms of their physical contribution to sea-level rise-related coastal change: geomorphology, regional coastal slope, rate of...Pendleton, Elizabeth A.; Hammar-Klose, Erika S.; Thieler, E.

Content Metadata Standards for Marine Science: A Case Study
The U.S. Geological Survey developed a content metadata standard to meet the demands of organizing electronic resources in the marine sciences for a broad, heterogeneous audience. These metadata standards are used by the Marine Realms Information Bank project, a Web-based public distributed library of marine science from academic institutions and...Riall, Rebecca L.; Marincioni, Fausto; Lightsom, Frances L.
Heavy rains from a tropical cyclone struck the islands of the Comoros in March, 2014. On the island of Anjouan in the Union of Comoros, these rains triggered landslides that displaced over 3000 people to refugee camps. The USGS and the OFDA with USAID are providing support and research assistance on these events. This photo is of Grand Comoros island, taken during a trip...
