New research from MBARI, Geological Survey/Commission géologique Canada, Fisheries and Oceans documents how the thawing of permafrost is affecting the Arctic seafloor. Deep sinkholes and ice-filled hills have formed "extraordinarily" rapidly on a remote part of the Arctic seafloor.: ow.ly/BwB550Ik435 CNN

QCL collaborating w/ USGS colleagues Gomberg, Dr. Nora Nieminski et al. to revisit Cascadia turbidite correlations for earthquake recurrence. @zzsylvester using dynamic time warping to correlate & developed new approach to evaluate correlation uncertainty! DM for details.

Enjoyed presenting and participating at the Pacific Cell 2022 Friends of the Pleistocene (#FOP) “Triangle of Doom v.2” field trip around the #MendocinoTripleJunction last week. Big thanks to the organizers and other participants!

And we’re off! Headed out to #sea for a coring & chirp #researchcruise in northern #Cascadia on the #BoldHorizon MarineGeohazards

Pause the #science (and the chirp survey) for some #whales passing by! #Cascadia #researchcruise

To better understand the geophysical characteristics and seismic history of the Cascadia Subduction Zone, USGS researchers conduct fieldwork at sea to collect evidence of turbidity currents from underwater landslides likely caused by earthquake shaking: usgs.gov/centers/pcmsc/…

Check out this short video that highlights our recent #usgs #researchcruise during which we collected sediment cores and geophysical surveys along the #cascadia #subductionzone usgs.gov/media/videos/c… #ScienceforaChangingWorld MarineGeohazards Dr. Jenna Hill Janet Watt Danny Brothers

Sure was a fantastic couple of days at Point Loma & Torrey Pines, sharing current research & catching up with fellow alums, friends, mentors, & students at the 30th anniversary SPODDS meeting. off the shelf edge Steve Hubbard @clasticdetritus Matt Malkowski Glenn Sharman Clastics Lab

It’s been a whirlwind of a change! CA ➡️ AK, USGS ➡️ DGGS.

Wrapped up #fieldwork in Kongiganak & Tuntutuliak, ALASKA, where we are doing risk assessments of #flooding & #erosion & #tundra loss. These communities need help. #CoastalHazards

Please apply to our collaborative USGS Mendenhall postdoc opportunity w/ J Gomberg, Dr. Lydia Staisch, J Covault, @zzsylvester & Dr. Nora Nieminski to study turbidite deposition & great earthquakes: usgs.gov/centers/menden…

Very proud to announce our publication in #Sedimentology that presents a magnitude of work on arguably the most extensive ancient submarine fan deposits in the world: #Neoproterozoic Zerrissene Group, Namibia. #stratigraphy #deepwater #lobes #facies onlinelibrary.wiley.com/doi/10.1111/se…

Check out our #StoryMap that documents significant #erosion caused by a single storm in #Arctic #Alaska. #coastalchange #coastalhazards #coastalresilience storymaps.arcgis.com/stories/f79f67…

Former DGGSer Rich Buzard (now at USGS) recently published a study about potential flooding in Alaska's coastal communities. Nora Nieminski, our Coastal Hazards Manager, contributed to this article about the study and flooding in the state. eos.org/articles/more-…
