SEABed Observation and Sampling System (SeaBOSS) operations were conducted north of Nantucket, MA as part of an agreement with Massachusetts Coastal Zone Management to map the geology of Massachusetts waters . The overall goal of the USGS–CZM mapping cooperative is to characterize the sea floor and shallow substrate inside the 3-mile limit of State waters, using high-resolution geophysical...

SeaBOSS operations were conducted north of Nantucket, MA as part of an agreement with the Massachusetts Office of Coastal Zone Management to map the geology of MA waters. The geologic and bathymetric maps help us understand the processes that have shaped the coast and how it has evolved over time, and thereby help evaluate the vulnerability of coastal environments to storms, sea-level rise, and...
Big Sur Landslide fly around animation
May 27, 2017
Big Sur Landslide fly around from May 27, 2017, a preliminary computer animation. The slide created roughly 13 acres of new California land.

Title: Underwater Secrets of the Hayward Fault Zone: Integrated 3D imaging to understand earthquake hazards Underwater imaging provides a unique opportunity to study urban fault hazards. How do we link surface structures to depths where earthquakes occur? How does "acoustic trenching" help us understand earthquake history?

Image of the Week: Okefenokee National Wildlife Refuge Fire Landsat 8's Operational Land Imager captures the scene as many acres burn in the Okefenokee National Wildlife Refuge. Series Description: "Image of the Week" is a series of videos produced by the USGS Earth Resources Observation and Science (EROS) Center featuring remotely sensed imagery of the Earth's landscapes. Each week a new...
Superimposed on beach photo: dense grid of blue dots across sandy beach and over ocean. Ditto 3 lines that cross the shore.

Frame from video of Cowells Beach in Santa Cruz, California, showing “pixel instruments” measured continuously during the video and used to estimate different coastal processes. The blue dots represent an array of pixels used by a computer program called cBathy to estimate seafloor depths (bathymetry). The red, orange, and yellow lines are cross-shore arrays of pixels used for measuring wave...

USGS ocean engineer Gerry Hatcher (left) and USGS postdoctoral oceanographer Shawn Harrison make adjustments to a computer controlling two video cameras on the roof of the Dream Inn, a 10-story hotel overlooking Monterey Bay in Santa Cruz, California. One camera looks eastward over Santa Cruz Main Beach and boardwalk, and the other southward over Cowells Beach. Since May 2017, the cameras have...
Distant view of the shore from a flat rooftop that is visible at bottom of image.

Snapshot, or first frame of from a 10-minute video shot on May 6, 2017, in Santa Cruz, California. Researchers at the USGS are using these and other video images to improve understanding and computer modeling of beach processes, especially those that change the coast. Half-hourly images are posted online during daylight hours. See also, the time-averaged image from this beach video .
Image in mostly black and white tones, showing distant view of beach stretching from bottom left to upper right.

“Variance” image produced from video shot at Cowells Beach in Santa Cruz, California, on May 6, 2017. The more the light intensity changes at a given spot, or “pixel,” during the video, the brighter the value assigned to that pixel. Motion tends to produce changes in light intensity. Note bright areas along and beyond the shore where waves were breaking. Researchers are using these and other...

Time-averaged image, or “timex,” created by averaging the intensity of light recorded at each spot, or “pixel,” during a 10-minute video taken at Santa Cruz, California, on May 6, 2017. Blurred white zones show where waves are breaking. Line between wet and dry sand shows the maximum height on the beach reached by the waves (“runup”). Researchers at the USGS are using these and other video images...
A cabin along Alaska's Arctic coast was recently washed into the ocean because the bluff it was sitting on eroded away.

Full-Circle Vista from Naukluft Plateau on Mars
July 3, 2017

Billions of dollars and a decade worth of research are on the line in the instant that a spacecraft touches down on Mars. When deciding where to land on the planet’s rocky surface, it is essential to analyze potential landing sites and their surface characteristics.

Subduction zone events pose significant threats to lives, property, economic vitality, cultural and natural resources and quality of life. The tremendous magnitudes of these events are unique to subduction zones, and they can have cascading consequences that reverberate around the globe.

Nor'easter
June 19, 2017

Living in the Outer Banks means living with the power of the sea. Jutting out from North Carolina’s coast into the Atlantic Ocean, this series of sandy barrier islands is particularly vulnerable to damage from major storms. In April 2016, another nor’easter was set to strike, but this time, Dare County officials were approached by their local weather forecaster with a new kind of prediction.

4D Photogrammetry of Mud Creek Landslide
June 15, 2017

USGS analysis of air photos collected June 13 shows that new land created by a May 20 landslide on California’s Big Sur coast is eroding. 

Satellite View of the Wilderness Breach
June 9, 2017

When Hurricane Sandy struck the south shore of Long Island, New York, on October 29, 2012, it caused substantial erosion of the beach and dunes. Storm waves cut through Fire Island National Seashore’s wilderness area, forming a breach. The resulting channel allowed water to flow between the Atlantic Ocean and Great South Bay.
