Some aesthetics from the past couple of days being out on the R/V Roger Revelle! “Cool” opportunity to be part of the PALMER LTER down in Antarctica 🇦🇶

Day-tripped to Grand Canyon NPS and hiked down to the Colorado River via Hermit’s Rest Trail. So much to take in along the way. Last photo is a fossilized tetrapod track from the Permian era. 🏜️

Myself at the #ASLO25: co-chair the zooplankton ecology session chaired by @yniimi808.bsky.social! Great talks, including the one by Yuuki himself. And, what can I do? I selfie - bombed Yuuki during his talk

Yesterday we had a very active day at #ASLO25 with five #NSFfunded presentations (sorry Sem I did not get you on picture!), including our ASLOMP scholar Serena, @yniimi808.bsky.social, Rocío and Amy! Lots of interesting chats with colleagues, and new collaborations on the horizon. Good job team!

I'm giving a talk on marine CO₂ removal (mCDR) while all my colleagues who work on mCDR are away at the Ocean Visions Summit in Vancouver. 🥲
Seminar poster for an Oceanography talk by Prof. David Ho from the University of Hawai'i at Mānoa. The poster features a headshot of a professor wearing glasses and a beige jacket, with a title reading "Marine carbon dioxide removal may be a future climate solution". The poster includes the university logo, contact information, and the seminar date of Thursday, March 27, 2025.

Spent the day at White Pocket, an area in northern Arizona with some of the most spectacular examples (1) of soft-sediment deformation in the Navajo Sandstone and (2) of the polygonal weathering that affects the resulting homogenous rock. These photos were taken with a drone (which is OK to use)
A view of the southern side of White Pocket. Polygonal weathering of the homogeneous sandstone layer at the top. In situ aeolian cross bedding is visible at the bottom.Polygonal weathering from the top.

One of the people fired from NOAA today is the director of the Ocean Acidification Program. That program also leads the U.S. government's effort on marine carbon dioxide removal (mCDR). The destruction of American science is incomprehensible.

One of my favorite rocks is limestone, primarily composed of calcium carbonate (CaCO3). This chunk I found near Payson, AZ, is from a shallow tropical sea 350-million-year-old. It’s called the Redwall Limestone and rich in fossils formed from reefs and marine life 🌊🪸🪨 #Geology #Ocean #Fossil

K is for Kiwa. In hydrothermal vents and methane seeps >1000m, exotic locales like Antarctica and the Galapagos, yeti crabs (of octonauts fame) thrive. Divorced from sunlight, they farm chemosynthetic bacteria on their own claws, waving them around! Art @thefuzzyslug.bsky.social #CrabAZ 🦀🧪🦑
Kiwa hirsuta, photo Alexis Fifis.

Elongated white squat lobster, seen dorsally. Most notable feature is hairy legs (hirsuta = hairy) and exceptionally hairy claws. The proximal parts of the claws are more than 2x the length of the carapace @thefuzzyslug artwork of a group of 15+ white Kiwa tyleri, all overlapping each other and taking up nearly the entire frame. This is true to their real life behavior. Some colored anemones are in the corners.
