@NWSBayArea Does that suggest more of the smoke from the Moss Landing lithium fire could shift toward Santa Cruz county?

Check out this eddy off the coast of Davenport, which is expected to shift winds in Monterey Bay to a northwesterly flow. #CAwx

@NWSBayArea Looks like a tornado touched down in on the main road Scotts Valley. I just saw the aftermath with multiple flipped vehicles and power lines down, but there’s multiple videos and photos on social media with a clear funnel cloud.

@alaskapublic I’m really missing the Iditapod this year! I fell in love with it last year and have been looking forward to it all year. I hope you can bring it back. #iditarod2024

Ever wonder what happens to all those sediment cores we’ve been collecting offshore and in lakes? Here’s a great overview of our USGS PCMSC core lab in Santa Cruz. Full video in the link shows some of our amazing imaging capabilities. #mud #science
USGS Coastal Change@USGSCoastChange
By collecting information about the past found within core samples, #geologists contribute towards a better understanding of how conditions may change in the future. Ready for a virtual tour of the @USGS Sediment Core Lab? We thought you'd never ask! ow.ly/bja250QCQM1

A nice piece about some of the behind the scenes work our group does - data access for all!
USGS Coastal Change@USGSCoastChange
To foster scientific exploration and understanding of the seafloor and offshore geohazards, the @USGS and @BOEM have collaborated to expand data access on the National Archive of Marine Seismic Surveys (NAMSS) portal: ow.ly/iS3450QuP2i

@Harold_Tobin Whoa. So interesting. I am in the middle of reading The Deepest Map by Laura Trethewey, which profiles the vessel/sub used here - another recommended read.
English
The sub is the DSV Limiting Factor, supported by the vessel DSSV Pressure Drop - aka, billionaire Victor Vescovo's passion project being used for science. Curious about it? I can recommend a great read on deep submergence science and adventure: Susan Casey's "The Underworld."

Amazing new paper on the 2011 Tohoku M9 quake/tsunami source. They used the deepest-diving submersible in the world to visit the trench and found a 50+ m scarp in the high-slip zone, which directly implies 80-120 m of coseismic shallow fault slip. nature.com/articles/s4324…

@waterbarnes @SFBART Hopefully I’ll see you there this week sometime!

This is a super cool new paper that highlights innovative, interdisciplinary methods for addressing earthquake hazards. Nice job @swampmonstah and team!

Alright, anyone have an invite code to share? I’ve missed the #science convos that used to happen here and we’ve got a lot going on with Cascadia and Alaska to share (mostly #earthquakes, #landslides, #tsunamis, + #paleoclimate) #Bluesky

@joshritter Several of the rocks around the center one look metamorphic (gneiss, schist), so if it’s from the same place, alas probably not a fossil. Any other other Geo Obies want to weigh in? @MelissaBerke @paulharnik @OberlinGeology

Any of my geologist friends know what kind of rock this might be? Found in a boulder field in a Brooklyn playground.

Happy #FieldworkFriday!

#Fieldwork: @USGS & @uafairbanks researchers are collecting sediment cores from shallow parts of the Bering Sea to reconstruct past #BeringLandBridge vegetation & sea ice and primary productivity as the ice age receded ~8,000-13,000 years ago. #ClimateR_D @NSF

Lots of new seafloor mapping happening along the #Alaska #Aleutian margin this summer! Our USGS Marine Geohazards project is supporting the mapping offshore Kodiak for #earthquake, #landslide and #tsunami #hazards. @JTWcoastal @DBrothersSC @MarineGeohazard
USGS Coastal Change@USGSCoastChange
Starting in May 2023 in the Gulf of Alaska, @USGS, @NOAAcharts, and partners are conducting a regional seafloor mapping campaign called Seascape Alaska: ow.ly/ZjQj50Os7Uf 📷: NOAA

I’m giving a talk @theNASEM today highlighting our work on submarine #landslides & #earthquakes in Cascadia —

@patton_cascadia @UW It’s going to be mid canyon (1500m) b/c of instrument depth limitations, but we should get a better handle on bottom boundary layer conditions there, so we can model any flows that run out farther. Although I’m guessing oceanographic triggered flows might not get that far.
English
Check out our exciting new tool for deep water oceanographic instrumentation. It will be deployed in Astoria Canyon, offshore Washington next month as per our joint project with @UW to investigate #oceanographic vs #earthquake triggered turbidity currents.

The Free Ascent Tripod tested here will be deployed in deep-sea environments along the Cascadia Subduction Zone. It will provide @USGS an up-close look at the seabed, measuring processes such as sediment transport thousands of feet beneath the surface: ow.ly/IWOM50N2uHE

I’m a little late for #TurbiditeTuesday, but isn’t this lovely? A new #albumcover for @MarineGeohazard!
