Institute Insights: Following black carbon into the Gulf

Black carbon from fires, fossil fuel combustion and other sources can travel far beyond where it is produced. UTMSI postdoctoral fellow Siddartha Sarkar and collaborators are studying where this carbon goes once it reaches the Gulf.

Through research cruises near Port Aransas and across the Mississippi River plume, researchers are tracing black carbon through seawater, particles and seafloor sediments to better understand its journey and where it ultimately ends up.

Learn more about this research in the latest story from the Port Aransas South Jetty.

Sunjida Alam

Sunjida is studying infaunal organisms, tiny animals that live beneath the sediment in tidal mudflats, to better understand how they shape and stabilize coastal ecosystems.

These small but powerful "ecosystem engineers" mix sediments, transport oxygen and nutrients, and influence sediment strength as they burrow. By collecting sediment cores and measuring sediment properties with specialized tools, Sunjida's research reveals how these organisms help maintain healthy tidal flats and resilient coastlines.

Her work improves our understanding of coastal stability, erosion, and the processes that support productive coastal ecosystems.

RECEPTION & ISLAND SCIENCE DAY IS ON RAIN OR SHINE! ☀️☔

There’s a lot happening at UTMSI this weekend! Join us Friday for the Island Science Day Reception and Saturday for Island Science Day.

Friday, October 2 | 5:30–7 PM
Kick off the weekend at the Island Science Day Reception at the Patton Center. This public reception will feature coastal science, conversation, and refreshments.

Saturday, October 3 | 10 AM–2 PM
Join us for Island Science Day, featuring interactive demonstrations, research labs, boat excursions, hands-on activities, live music, outreach booths, and more. The event is free and open to all ages.

Both events will take place rain or shine. The only activities that have been canceled due to weather are the boat excursions on Saturday.

Come celebrate 85 years of marine science at UTMSI and 20 years of the Mission-Aransas National Estuarine Research Reserve with us!

Island Science Day Weekend is almost here! 🌊

Join us Friday, October 2, at 5:30 p.m. for the Island Science Day Reception at the Patton Center. This adult-focused evening will celebrate 85 years of discovery at UTMSI and 20 years of coastal stewardship, research and community engagement through the Mission-Aransas National Estuarine Research Reserve.

Enjoy w**e and cheese while hearing about the discoveries that have shaped UTMSI and the Reserve, and get a look at what’s ahead for the future.

Then, come back Saturday, October 3, from 10 a.m.–2 p.m. for Island Science Day, our open house featuring hands-on activities, marine science demonstrations, tours, vendors, live music and more.

Come celebrate our past, explore our present and discover what’s next. Friday’s reception and Saturday’s Island Science Day event will take place rain or shine!

Institute Insights: Nesting season ends; protection continues

Kemp’s ridley sea turtles return to Texas beaches each spring to nest, including along Mustang Island. In 2026, nearly 700 Kemp’s ridley nests have been documented across Texas, with 40 on Mustang Island, breaking the state and island nesting records for the second consecutive year.

ARK staff supervisor, Andrew Orgill, shares how beach patrols, monitoring and nest protection are helping support the recovery of this critically endangered species, and why every nest and hatchling matters.

Learn more about Kemp’s ridleys, this year’s record nesting season and the continued work to protect sea turtles in this story from the Port Aransas South Jetty.

Researchers from UTMSI, UTIG, and the Jackson School of Geosciences recently gathered in Port Aransas to generate innovative research ideas and future partnerships at the intersection of marine science and geoscience. We were especially pleased to welcome Gregg Robertson, whose support through the Marsha and Gregg Robertson Research Endowment helped make the workshop possible. 🌊🔬🤘

Izzy Nelson

Izzy studies how melting glaciers influence mercury levels in marine food webs in the Gulf of Alaska. As glaciers melt more rapidly due to climate change, they can transport mercury, a neurotoxic metal, into coastal waters, where it may accumulate in fish and other marine life.

By measuring mercury in water, sediments, invertebrates, fish, and even fish eye lenses, Izzy's research reconstructs how mercury exposure changes over a fish's lifetime. Her work helps scientists better understand how climate-driven environmental changes affect marine ecosystems, fisheries, and the coastal communities that depend on them.
