Recovered our sediment traps yesterday and redeployed them this morning. Re-recovering them tomorrow before we head back to port to *hopefully* meet our container to really spin up operations 🌊

Enter creative sampling for some trace metal clean surface water in absence of our rosette. Feat: crane+ carboy and small boat + carboy (following a glider deployment). 🌊

First sediment trap cross deployed! Making due with 12 of the planned 60 PITs we happened to carry on the flight here while we wait for our container 🌊

And we're off on part 1 of our SUBSEA cruise in the South Atlantic aboard the Falkor, Too. One of our shipping containers is delayed so we're improvising (see the air conditioning size HEPAs and making some new sediment trap brine) for a shake down station before the container arrives 🌊

Science friends! We recently started using an inherited dynamax rp-1 peri pump (with a single spare peri pump tubing) to help circumvent clogging with our mass spec.... But I'm in tubing misery and can't seem to find the right bridge length (seems to be 180mm??). Anyone have a tubing part no.?

Happy international day of women and girls in science! Grateful for this powerhouse of a postdoc group that I work with 💗🥳

Silly side observations of my cats help lighten life sometimes. Here, I present, the growth of my cat olive's fur from 7 days before she got shaved against my wishes (miscommunication), day 0, and day 365! We made it

Phew, have spent the last few months grinding away at cruise prep and am officially packed in containers and done for the year! Some acid washing stats: ~800 L of bottles / carboys ~7 m² of filters

180 L of trace metal clean sediment trap brine packed away today! 🤞🏻 For a safe shipment

Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

Spent the last two weeks in a workshop on ocean primary production funded by the @schmidtsciences.bsky.social as part of the Ocean Biogeochemistry Virtual Institute. Now time to finish cruise prep!

Localized nutrient colimitation of phytoplankton growth rates across the subtropical South Pacific Ocean www.pnas.org/doi/abs/10.1... #jcampubs 🌊

Iron release into the Southern Ocean from thinning Antarctic glaciers could boost carbon absorption. Iron leached into seawater from exposed mountain tops boosts phytoplankton which take up CO2 through photosynthesis. The question is how much and over what timescales. #climate 🧪

Last HOT cruise of the year (for me) ✅

Underway for HOT361!

The amount of ice flowing from Thwaites Glacier in West Antarctica has doubled in the span of three decades. These satellite images from 2001 and 2019 show the fracture and retreat of the glacier ice tongue floating on the Amundsen Sea, as it's melted from below. 🛰️ NASA

It's been a whirlwind of the last few months simultaneously sailing on HOT cruises and preparing to ship things for a S. Atl cruise. Honestly.... I'd rather rewrite my thesis than wash another bottle right now 🤣🙃. But today, I loaded for another HOT cruise AND moved my last items into acid. 💃🏻🥳

A Sharon Begley byline, almost 5 years after her death. Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written." Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating. 🧪🧬🧫

This week, I cleaned 100L of carboys, 36 L of bottles, and 360 McLane pump filters 🙀. Trying to catch up on desk work today, and... #CatsOfScience

💥California marine biogeochemists! So Cal BOOM* is at UCLA on November 22, 2025 (*Biogeochemical Ocean Obs & Models). This is an event for grad student and post-doc marine biogeochemists of all kinds. More senior peeps (like me) are also welcome! 💥 Register here: socalboom.wordpress.com

Check out this write up describing what we're working on to understand biogeochemical cycling across different layers of the euphotic zone. The SUBSEA team is currently out on HOT-360 deploying SIX sediment trap crosses and McLane pumps this time 🎉 nautil.us/modeling-the...

11 days into a government shutdown. This is where we are:

Some views from HOT-359! 🌊

Getting ready for HOT-359, featuring double the niskins! Working on testing a new rosette before shipping it off 🎉

Well that's a new one for me... 🤣 (No Niskins were irreparably harmed)

California! Set a reminder in your phone to call the gov’s office to tell Newsom to sign these five bills. The guy’s mercenary as hell so if he thinks the wind is shifting in favor of trans rights (it never shifted! Trans rights are human rights!) we could flip him. Info below. Call: 916.445.2841

If you are American faculty and aren't loudly speaking out against what's happening at @tamu.bsky.social right now, I suggest you read the news. Absolutely despicable actions by their admin and true loss for reliable, unbiased higher education. Acknowledging trans people exist is not "ideology".

Breaking News: The EPA moved to stop requiring polluters to report their emissions of greenhouse gases. The proposal would end a key tool the government uses to track carbon dioxide, methane and other gases that are driving climate change.

That's a wrap on HOT358! Featuring the... fun... wire angle on my last trace metal cast post hurricane Kiko passing through

Successfully recovered our 5 sediment trap crosses (60 PITs!) and spent the rest of the day homogenizing, subsampling, and filtering for macronutrients, trace metals, organics, DNA, et al. 🌊

Another day at ALOHA, feat. a glider search party and recovery 🌊

Lots of tricho out here at station ALOHA 🦠🌊

Busy day of deployments on the R/V Kilo Moana at station ALOHA. Seaglider, wire walker, and 5 sediment trap crosses spanning 75-300 m (including two optical sed traps ‼️). We're working to understand export and recycling across the euphotic zone 🌊🧪

After much delay, HOT358 is officially underway 🌊👩🏻‍🔬

Finally loading for HOT358 tomorrow (after it's been continuously delayed since April), and I'm beginning to think this cruise is cursed 🤣🤷🏻‍♀️

🌊With the Fall semester upon us, it's time to start thinking about recruiting/applying to grad school for 2026. If you are a marine scientist looking for a graduate student, I've created a form where you can add your name and other info: docs.google.com/forms/d/e/1F... Please share widely! (1/2)

📢 New paper in @nature.com Microbes rock 🎸🤘 with sulfide and iron minerals I am very excited to share our recent study, which describes a previously unknown microbial energy metabolism ⚡⚡⚡🦠🧫⚡⚡⚡ 🆕 Microbial iron oxide respiration coupled to sulfide oxidation - MISO www.nature.com/articles/s41...

As the school year begins again, I was reminded how utterly stressed I was one year ago because I had no clue what my next step was. Crazy to think how much changes in a year!

🌊 ❄️ A running thread on press coverage of the decommissioning of the Research Vessel/Ice Breaker N.B. Palmer (in rough chronological order): 1.- NSF plans abrupt end to lone U.S. Antarctic research icebreaker (Science, July 28th, 2025):

The National Science Foundation will stop operating the Nathaniel B. Palmer icebreaker and slash polar science funding by 70 percent, devastating Antarctic research

New: NSF has reinstated the suspended UCLA grants, following yesterday's court order. Here's the email to Chancellor Frenk. (The ~490 NIH & 2 DOE grants remain suspended)

There are a lot of details in yesterday's sweeping executive order, but the bottom line is that it gives political appointees immense power over scientific grants, which have until now been stewarded by career civil servants and experts. My reporting: www.nature.com/articles/d41...

Great feature on influence of Asian dust deposition on phytoplankton in the North Pacific Gyre 🌊

California’s wildfire seasons are starting earlier and earlier, thanks to climate change.
