Surficial Geology Map of Nantucket and Marthas Vineyard, MA
Map showing the surficial geology from this study and Baldwin and others (2016) with equivalent onshore geology (adapted from Stone and DiGiacomo-Cohen, 2009). The areal extents over which offshore subsurface geologic units crop out at the sea floor were interpreted from seismic-reflection data.
Map of volcano threat category designated by color
Map showing the locations of all U.S. volcanoes with their threat category designated by color. Very high threat is red, high is orange, moderate is yellow, low is green, and very low is blue.

Piping Plover Habitat, Cedar Island
The beach-dependent shorebirds project at the Woods Hole Coastal and Marine Science Center models current and future habitat availability for nesting shorebirds in an effort to map current and likely future habitat availability on a range of sites along the U.S. Atlantic coast. Sites include beaches with minimal human-presence, such Cedar Island shown here off of the

Data visualization with scaled options applied
Data visualization with (A) fixed and (B) scaled options applied. Examples of NSM and SCE are also displayed (C and D respectively). The data itself has not changed – only the scaling and statistic selected through the DSAS Data Visualization tool.
Mount Shasta, a steep-sided Cascade Range stratovolcano in Northern Ca
Mount Shasta, a steep-sided Cascade Range stratovolcano in Northern California, looms above Little Glass Mountain, a thick obsidian flow erupted from the Medicine Lake shield volcano about 1,000 years ago. These are just two of the young volcanic areas monitored by the USGS California Volcano Observatory. USGS photo.
Seismic Collage
Image showing a collage of examples of multi-channel and single-channel seismic data collected by the USGS, seismic equipment deployed from a research vessel, and seismic equipment on a research vessel. These data are critical to the CMG Program as they define the geology in marine and coastal environments.
DSAS Summary Report
Example of a section of DSAS summary report highlighting the use of DSAS_group to organize output statistics.
ShakeAlert sensor station being serviced by USGS personnel
A USGS electronics technician performs maintenance on a ShakeAlert Earthquake Early Warning (EEW) sensor station, located in the San Francisco Bay Area. ShakeAlert station components include strong-motion accelerometers, solar panel and battery power systems, and communications & telemetry equipment for communication with the wider ShakeAlert network.

SEABOSS Collage
SEABed Observation and Sampling System (SEABOSS) (center image) and the MiniSEABOSS (right) designed for rapid, inexpensive, and effective collection of seabed imagery (photographs and video) as well sediment samples from the coastal/inner-continental shelf regions. Images from coastal Massachusetts show purple algae-encrusted cobbles and boulders covered with sea-stars (
