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

[Dr. Jenna Hill @cairya]

@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! https://t.co/OmazN76fWS

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: https://t.co/xTrdSzBU82

Happy 2024! Let’s chat science - https://t.co/zM2XfoaVzW ⚒️

[Dr. Jenna Hill @cairya]

@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.

[Dr. Jenna Hill @cairya]

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

[Dr. Jenna Hill @cairya]

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

@AsivileZee Yes, that was fast! Im all set thanks.

[Dr. Jenna Hill @cairya]

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

[Dr. Jenna Hill @cairya]

@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

Happy #FieldworkFriday!

[USGS Climate @usgs_climate]

#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

[Dr. Jenna Hill @cairya]

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: https://t.co/Q9wL5rJ0Wf

I’m giving a talk @theNASEM today highlighting our work on submarine #landslides & #earthquakes in Cascadia —
Bathymetry and Topography at the Land-Ocean Interface: Committee on Solid Earth Geophysics Spring 2023 Meeting https://t.co/4hvDMFds2S

[Dr. Jenna Hill @cairya]

@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.

[Dr. Jenna Hill @cairya]

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.

[USGS Coastal Change @USGSCoastChange]

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: https://t.co/9sALrimSNk

Road impacts from this storm could last for a bit in some areas. Check local road conditions at https://t.co/NX0Ez7ZHhx.

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