This is the way!!! 🤜🤛

At some of my grocery stores, they are wrapping individual produce in plastic. Why!?!? So unnecessary.

[Correction: ROV *Little Hercules (with towsled Atalanta). ROV Hercules is rated to ~4,000m and ROV Little Hercules is rated to ~6,000m.]

Oh you know you’re in deep when the cabbage makes its first appearance! 😅 Cabbage and over-ripe apples… that’s an interesting timeframe.

Plastic is everywhere.

On today’s dive, the E/V Nautilus/ ROV Hercules encountered a crushed plastic bottle on the abyssal plain- in the remote Pacific (Cook Islands @ 5,198 meters).

♻️ I challenge everyone to swap at least one single-use plastic item. Small steps for more eco habits. 🌊🧪🌎

Hahaha ironically I always missed fresh salads on long expeditions! That wouldn’t make for good livestream banter… but I could tryyy 😆

Hahaha true!

Deep-sea diving pigs 🐷

Hahaha if a nodule exploration company doesn’t name their AUV/ ROV “the pig”, they’re missing a great opportunity.

Massive nodule fields!!! Crazy, huh? Not unexpected, of course, but the density is striking. Great dive selection by the NA176 Team(s).

Thanks @kbyip.bsky.social! @khagolnomy.space I often refer to polymetallic nodules as “forbidden truffles” 😉

Thank goodness! I’ve been in touch with some of the Percy ops folks- all survived. So thankful to hear you’re safe!

Definitely interested to hear your feedback. It’s mainly focused on MIS 2, 4, & 6. Our Fe-oxide grain provenance proxy yielded some interesting results. Looks like we may have even more questions about ice transport processes!

Bit of good news this morning.
Minor revision request for our new manuscript examining presence/ extent of the Barents Sea Ice Sheet during past glacial maxima 🧊🪨🌊 Unlocking Arctic paleoclimate!

Grateful for thoughtful Reviewer feedback.

Last time I was home, I grabbed some samples for my "garden collection" (because, why not!):

In conjunction with @moreorloess.bsky.social's comments, plenty of sub-rounded samples across my childhood home.

🗺️ Geologic Setting: Wisconsin- just north of the LGM/ MIS 2 terminal moraine and south of the widespread drumlin fields. I'm voting ice transport. Pics below.

The news is starting to roll-in from today’s NASA-JPL terminations. Sending the biggest virtual hugs to my extended JPL Family 🩵🥺

Same concerns.

Absolutely heartbroken for my NASA-JPL colleagues. Tomorrow is going to be a challenging day 💔

[JPL Peeps- y’all know how to directly reach me. PLEASE reach out if you need anything. Love you Guys!!!]

Space Deer. Doing their thang. Every has a job to do. 😆🦌

Nor’easter inbound. Obviously that meant recon time. Here’s a quick clip from Virginia today. #VAWx

I know we’ve had this discussion before- but this is a hill I will die on. ALWAYS WINDOW SEATS. And yep, that shade is staying open. 👀📸

I mean, that’s sound advice.

Heart rate data from recent workout shows distinct peaks (rounds of Oly lifting/ running/ ski). 📈 : Whoop

Trying my best to mimic Vostok δ¹⁸O data. If you squint hard enough, you can see that pesky MIS 4 rearing its face.

Tiny shoutout to my fellow grad student @ocnogrphr.bsky.social! He’s returning to our Alma mater as part of our dept’s lecture series- as a seasoned postdoc!

Hey Ryan- don’t forget to swing by Borjo ☕️ Enjoy your visit to ODU!

Happy to see you had a good race 💫

Hmm, squishy but pliable. I’d say around gypsum, so Mohs 2.
