Fresh off the preprint server! @maratimes.bsky.social and I show how data from the overlapping SWOT and PACE satellite missions present a step forward in our ability to observe linked biogeochemical-physical processes in the ocean.

We look forward to chatting about this with folks at #OSM2026! 🌊

Physical controls on heterogeneous mesopelagic biogeochemistry Communications Earth & Environment - A patchy distribution of biogeochemical properties in the ocean interior arises from the combined influence of biological and physical processes.

Surface ocean processes impact structure deep into the ocean interior. In our perspective paper, @maratimes.bsky.social, grad student Katarina Merk, and I discuss using physical perspectives to interpret subsurface biogeochemical distributions and why we as a community should care! 🌊

How well can we quantify when 1.5 °C of global warming has been exceeded? Abstract. Parties to the 2015 Paris Agreement agreed to limit the long-term increase in global average temperature to well below 2 °C and pursue efforts to keep temperatures below 1.5 °C relative to p...

New discussion paper just dropped that’s taken shall we say a little work to get this far … essd.copernicus.org/preprints/es... please be kind. Not on an at all sensitive topic in the slightest.

On Thursday (17:28 - 17:38) PhD student Alejandra Lopez will present
"H44G-07: Forecasting Hydrogen Sulfide Emissions Using Satellite-Derived Water Quality Metrics and Machine Learning at the Salton Sea, California"

Everyone always asked why I moved to landlocked Colorado to do oceanography. Because it was the world's largest concentration of climate scientists. Because of NCAR and NOAA.

In Boulder, fewer are alarmists; they are overwhelmingly problem solvers.

NCAR's science is patriotic. Vought is not.

🌊

It's a been a tough week at Brown given the tragic events on campus but I know they are glad to be with friends and colleagues at AGU.

both Ashely and Alejandra are presenting community science work that started as part of a @thrivingearth.bsky.social project!

REU student Ashely Aguayo will present a poster on Thursday morning
"H41P-1392: From locals to labs: Community science reveals seasonal phytoplankton patterns in the Salton Sea"

On Thursday (17:28 - 17:38) PhD student Alejandra Lopez will present
"H44G-07: Forecasting Hydrogen Sulfide Emissions Using Satellite-Derived Water Quality Metrics and Machine Learning at the Salton Sea, California"

(Cassidy and Emily are both great scientists and applying to PhD programs!!!)

Undergraduate Cassidy Charles will be presenting a virtual poster on Wednesday
"OS33B-1124: Transient Overyielding in Ocean Microbial Communities"

If you're at #AGU25 stop by presentations from my lab! @microbialplanet.bsky.social bridge to PhD fellow @yunqianhu.bsky.social (also w/ @akrinos.bsky.social) will be presenting a poster Wednesday
"OS33B-1119: Microbial Assemblages in the Context of Basin-Scale Variability Across the North Atlantic"

The role of Lagrangian drift in the generation of surface waves by wind A nonlinear stability analysis entirely in the Lagrangian frame is conducted, revealing the fundamental role of the wave-induced mean flow in modifying further wave growth and providing new insight in...

this work is with @nickpizzooceans.bsky.social and we're excited to share a preprint: arxiv.org/abs/2508.02580

IBES Voss Fellows bring climate research to the community Members of the 2025-2026 Voss Undergraduate Fellowship cohort have shared their research with local audiences through the Conversations in Science series at Providence’s Hamilton House.

Undergraduate researcher Wyatt presenting his ocean modeling research!

Brown begins work on $7 million microplastics research initiative Brown’s team in the SIMCoast initiative will focus on modeling microplastics in the Narragansett Bay. 

Brown faculty, including IBES fellow @baylorfk.bsky.social & affiliate @maratimes.bsky.social, are part of the new SIMCoast initiative modeling microplastics in Narragansett Bay.

“It’s a fantastic way to do interdisciplinary work and learn from others,” Freilich told @browndailyherald.bsky.social.

IBES is hiring! The Student Transformative Engagement Pathways (STEP) Program Director will guide development and execution of expanded paid internships & research assistantships in climate, sustainability, and the environment for undergrads across Brown. brown.wd5.myworkdayjobs.com/en-US/staff-...

Woo, riding around the edge of an eddy and sampling for omics and sensors- new use case. I was recovered at the blue dot - started at a red dot to the right, drifter track in the center. Eddies can bring nutrients towards the surface and stimulate productivity. Also useful for robot joyrides.

Scientists tap 'secret' fresh water under the ocean, raising hopes for a thirsty world Scientists conducting a first-of-its-kind drilling operation have extracted samples of fresh water hiding in massive reservoirs deep under the ocean.

Our fieldwork doesn't only happen at sea!
C-CoMP researchers working with @maratimes.bsky.social collected Providence River water to test extraction methods for samples collected on C-CoMP cruises. In terms of filtering speed, 5 L of Sargasso sw = 50 mL of Providence River water!

🔬Emily Hu (@yunqianhu.bsky.social‬) is a C-CoMP B2P Fellow working with @maratimes.bsky.social & @akrinos.bsky.social at Brown. She uses microbial sequence data and computational tools to uncover how biotic🦠& abiotic drivers shape microbial community assembly in the North Atlantic Ocean 🌊.

IBES affiliate @maratimes.bsky.social, an assistant professor of Earth, Environmental, and Planetary Sciences, lost her first federally funded grant from NASA earlier this year.

“One of my big concerns is that the trust in science and in scientists is broken,” she told @virginiagewin.bsky.social.

How your research can survive a US federal grant termination Researchers in the United States are filing appeals, seeking court remedies, turning to philanthropy and starting GoFundMe campaigns.

@virginiagewin.bsky.social writes about terminated federal grants, including one on which I was PI

"The funding had been helping a multi-institutional team working with community advocates and citizen scientists to analyse air quality around the Salton Sea,

... “One of my big concerns is that the trust in science and in scientists is broken,” says Freilich. It weighs on her that scientists might not be able to follow through on the promises they made to community partners, such as sharing the air-quality findings in a timely manner."
