It's #FieldworkFriday and the U.S. Geological Survey (USGS) is back on the beaches of southern #California, where we use jet skis and ATVs equipped with GPS to monitor coastal change. These vehicles allow scientists to gather elevation data along ever-changing coastlines: https://ow.ly/i88i50U3jX4
What better way to celebrate #spookyseason than by revisiting some of the strangest, least-studied ecosystems on earth: deep-sea chemosynthetic communities found at seafloor spreading centers such as Escanaba Trough: https://ow.ly/bUQF50TXvTR
If your seismic data is haunted by "ghost reflections" that obscure details in the imagery, who you gonna call? The U.S. Geological Survey (USGS), of course: https://ow.ly/a6Ib50TVKa4
This #FieldworkFriday takes us to northwest #Alaska, where the U.S. Geological Survey (USGS) uses camera installations to monitor long-term coastal processes such as bluff erosion, movement of sandbars and ice floes, and sediment entrainment and transport by ice: https://ow.ly/WG5S50TxjyP #coastcam
New USGS-led research finds that subtle shifts in wave direction, driven by multi-annual climate variability, are causing significant patterns in coastal erosion and sediment deposition along the Pacific Northwest coastline. The findings demonstrate how engineered coastal structures like jetties can intensify these natural processes, with potentially far-reaching implications for coastal management: https://ow.ly/jfnz50TrayL
Gouge coring: Not as violent as it sounds! Scientists use gouge cores to investigate sediment stratigraphy in marshes and other terrestrial areas.
The Eel River in Northern California is located near the Mendocino triple junction, where three seismic faults meet: the Cascadia Subduction Zone, the Mendocino Fracture Zone, and the San Andreas Fault.
Sediments preserved in coastal settings such as the lower Eel River valley may preserve evidence of past seismic activity like subsidence or tsunamis. Understanding how these faults behaved in the past is key to determining how they might behave in the future. #FieldworkFriday
Like a natural #seismograph, sediments in lakes and marine settings can record past #earthquake activity, helping U.S. Geological Survey (USGS) scientists better understand the frequency and intensity of movement along a fault.

Have you ever thought about viewing Mercury from SPACE? No not the planet, the element, Hg. USGS scientists are creating a method to track mercury pollution in South San Francisco Bay using satellite imagery. These researchers from the Western Geographic Science Center and California Water Science Center are linking water color to water quality.
Mapping mercury pollution around the South Bay could help inform bay management, restoration activities, and inform climate change adaptation.
Join #geologist and #surfer Jon Warrick to learn how U.S. Geological Survey (USGS) #coastal and #ocean #geoscience contributes to a better understanding of wave formation and behavior—critical information with a broad range of applications, not least of which is surfing! https://ow.ly/c7ab50PjJYR #OceanMonth
The 1957 magnitude 8.6 Aleutian Islands earthquake was one of the largest earthquakes of the last century, unleashing a destructive tsunami that brought waves between 6 to 12 meters high (20-40 feet) to the #AleutianIslands and #Hawaiʻi. Research from U.S. Geological Survey (USGS) and partners sheds new light on the 1957 earthquake, revealing critical details that enhance our understanding of tsunami threats to the #HawaiianIslands: https://ow.ly/8Abn50SliE3
The U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center's Marine Facility in #SantaCruz is the operational arm of PCMSC, providing #engineering, #mechanical, and #electronics expertise for field operations along the coast, in the nearshore environment, and in the deeper waters of the #ocean: https://ow.ly/8L0o50SirSR #FieldworkFriday #OceanMonth
What’s going on in submarine canyons—the most mysterious of canyons?
USGS and partners are on the case! Their research is giving unprecedented insights into complex, seemingly otherworldly deep-sea ecosystems.
