Sources of Microbial Contamination at Public Beaches, Santa Barbara

The focus of this study is on analysis of existing hydrologic, chemical, and microbiological data; collection of surface-water and shallow ground-water hydrologic, chemical, and microbiological data; and characterization of dissolved organic carbon composition.

Alaska North Slope LiDAR

High-resolution light detection and ranging (lidar) elevation data were acquired along the north coast of Alaska between 2009 and 2012. The lidar acquisition, from Icy Cape, Alaska to the United States/Canadian border, comprised approximately 11,000 km2. The airborne lidar data were acquired in support of the U.S. Geological Survey...

Saltwater Intrusion

Saltwater intrusion has occurred to some degree in many of the coastal aquifers of the United States. Since saltwater cannot be used to irrigate crops or be consumed by people, saltwater intrusion can be very problematic to coastal communities that rely on fresh groundwater supplies for the livelihood. The USGS studies how excessive groundwater pumping, sea level rise, and other factors...

Erosion of a Sea Stack Over 100 Years

The following photographs show the demise of Jump-Off Joe, a one-hundred-foot-high sandstone formation known as a “sea stack”. In 1890, the sea stack was composed of middle Miocene concretionary sandstone of the Astoria Formation. Yaquina Head on the Horizon is composed of middle Miocene basalt flows and breccia. Note remnant of Pleistocene terrace deposit along the wave cut bench on the stack...

Estuarine Processes, Hazards, and Ecosystems-Study Sites

Estuaries are dynamic environments where complex interactions between the atmosphere, ocean, watershed, ecosystems, and human infrastructure take place. They serve as valuable ecological habitat and provide numerous ecosystem services and recreational opportunities. However, they are modified by physical processes such as storms and sea-level rise, while anthropogenic impacts such as nutrient...

Estuarine Processes, Hazards, and Ecosystems

Estuarine processes, hazards, and ecosystems describes several interdisciplinary projects that aim to quantify and understand estuarine processes through observations and numerical modeling. Both the spatial and temporal scales of these mechanisms are important, and therefore require modern instrumentation and state-of-the-art hydrodynamic models. These projects are led from the U.S....
