I'm excited to share our recently published paper in Marine Chemistry which uses amino acid enantiomers to evaluate the bacterial contribution to dissolved organic matter. Check it out here! sciencedirect.com/science/articl…

My group Western Geographic Science Center is looking to hire a student contractor! Current or recent students with remote sensing, spatial analysis, programming background 🧵

Very excited to head to the Escanaba Trough next week with a great group of researchers from the USGS PCMSC! We'll be cruising for three weeks collecting sediments, rocks, pore waters, and more. Can't wait to see #ROVJason in action!

And they're off! A multidisciplinary team from USGS, NOAA and BOEM are embarking on a three-week research expedition to Escanaba Trough, a seafloor spreading center 200 miles off the Northern CA coast. Learn about the expedition here: ow.ly/Mf1i50Jj9a1

My first in person view of the sea floor was an awe inspiring experience. We got amazing views of a chimney field at Escanaba Trough thanks to #ROVJason. Can't wait to see more!

Embarking on a three-week deep-sea research expedition to Escanaba Trough requires a lot of preparation. Almost everything the scientists need to conduct their research must be transported onto the ship with them. Learn more here: ow.ly/v9gg50JllzU #Escanaba2022

It's been awesome to work with both ROV Jason and SUV Sentry! Together they've helped us study this otherwise hard to reach hydrothermal environment. #Escanaba2022

How's that saying go about "red sky at morning"? 🤢 Check out this update from the ongoing Escanaba Trough expedition with NOAA Ocean Exploration Woods Hole Oceanographic Institution (WHOI) Bureau of Ocean Energy Management : ow.ly/Wgk650Jrt75

Feeling very fortunate to spend #WorldOceansDay out on the ocean sampling the Escanaba Trough! #Escanaba2022

As a chemist, I never got quite as excited about rocks as some of my geologist colleagues. But the rocks we've been finding at Escanaba Trough have definitely changed my mind! #Escanaba2022

We got to see lots of sea pigs from the cameras on Jason while it was at the bottom of the ocean. Love this video of some of the sea pig highlights 😂

On the boat for over three weeks there weren't any obvious markers of time passing, so coming back to SC in many ways feels like a jump into the future. Specifically, suddenly: 1) summer temperatures are here 2) summer produce is here 3) everything is way more expensive

Excited to be making my first measurements on sediment samples the Escanaba Trough. These samples represent multiple sediment cores spanning active and inactive hydrothermal as well as pelagic deep sea environments. Check out all those different colors!

Check out this summary of our cruise to the Escanaba Trough in June!

Today is my first official day as a Mendenhall Postdoctoral Fellow with the USGS! My research will investigate the organic geochemistry of marine mineral host sediments and how carbon storage may be impacted by hypothetical deep sea mining.

Just out!✨Elephant seals collecting high-res temp data showed us that eddies in the northeast Pacific can benefit these deep-water predators & that physical aggregation may play a larger role than nutrient enhancement Elliott Hazen Rachel Holser Daniel P Costa doi.org/10.1016/j.dsr.…

During #MappingGalapagosVents, the research team is testing a new #SeaFloorMapping system. Interferometric Synthetic Aperture Sonar #InSAS combines bathymetric data w/ acoustic imagery. Simply put, they're mapping using sound rather than light to reveal more about our Ocean. 1/2

Just got back from an incredible expedition studying hydrothermal vents along the Eastern Galapágos Spreading Center. Check out this post to learn more!

New publication! Check out our recent work using solid-state NMR and nitrogen isotopes to suggest a new paradigm for marine DON persistence pnas.org/doi/10.1073/pn…
