A previously unknown significant source of carbon just discovered in the Arctic has scientists marveling at a once overlooked contributor to local coastal ecosystems – and concerned about what it may mean in an era of climate change.

Plastic pollution has contaminated every continent on Earth. It kills wildlife from whales to sea turtles. Some of the smallest plastic particles, called nurdles, are among the most insidious. It's difficult to even catalog the scope of the problem. But one group of citizen scientists is going to try. And a recent lawsuit against a plastics manufacturer is about to give them a major boost.

PORT ARANSAS, Texas – After more than two years of roof repairs, window installations and building reinforcements, the scientists, staff members and students at the University of Texas Marine Science Institute (UTMSI) have an end in sight for their ongoing effort to rebuild after Hurricane Harvey, thanks to help from the U.S. Congress.

On a clear day on the beach in Port Aransas, Jace Tunnell noticed clear and multi-colored pellets collecting on the sand at the high tide line. On closer inspection, he discovered the pellets were tiny, round bits of plastic. And there looked to be millions of them.

The U.S. Department of Commerce's Economic Development Administration (EDA) has awarded a $5 million grant to The University of Texas at Austin to repair a large laboratory building on the UT Marine Science Institute campus in Port Aransas and help establish a new Center for Coastal Ocean Science.

You can swim, but you can't hide. Even hard to find living things in the bays and estuaries in the Coastal Bend are being identified as researchers from The University of Texas Marine Science Institute (UTMSI), Mission-Aransas Reserve, and Texas A&M University Corpus Christi (TAMUCC) team up with the Smithsonian Institution's Marine GEO (Global Earth Observatory) program for an ambitious project to identify precisely what lives in the near-shore waters.

On June 3, 1979, an oil rig called the Ixtoc I exploded off the coast of Campeche, Mexico, triggering what at the time was the worst oil spill in history. Even today, Ixtoc is eclipsed in the Gulf of Mexico only by the Deepwater Horizon disaster of 2010. Ixtoc's damage was observed for decades along the Texas coast, where experts at the University of Texas Marine Science Institute study the impact of the oil spill to this day and explore ways to contain the damage from future disasters.

The University of Texas at Austin Marine Science Institute can feel like the edge of the world. It stands on a corner of Mustang Island, surrounded by windswept grassy dunes and a seemingly endless expanse of Gulf water. But this unassuming campus is perfectly positioned to study our planet's largest resource. MSI isn't an edge; it's a forefront.

As Earth's climate warms, experts predict the rate of greenhouse gas emissions from thawing Arctic permafrost and peat will rise, which will further boost climate warming. Because the rate of permafrost thaw varies widely across the Arctic and data from remote areas is limited, it's been challenging for scientists to monitor actual changes on the ground.

A team of researchers from Uppsala University in Sweden, The University of Texas at Austin and elsewhere, have found new evidence that strengthens the hypothesis that the first complex life forms, called eukaryotes, arose from the merger of two simpler life forms. The same team previously identified living relatives of ancestors of eukaryotes, while this latest study shows how those ancestors might have shared the work of metabolism with bacteria they acted as hosts for.

Scientists at The University of Texas at Austin's Marine Science Institute have discovered nearly two dozen new types of microbes, many of which use hydrocarbons such as methane and butane as energy sources to survive and grow—meaning the newly identified bacteria might be helping to limit the concentrations of greenhouse gases in the atmosphere and might one day be useful for cleaning up oil spills.

Even a Category 4 hurricane doesn't kill the mood for coastal fish – and that's good news for all species, as well as for a multibillion-dollar recreational fishing industry. As extreme weather patterns threaten to bring more and larger storms to the Gulf Coast, new findings from the University of Texas at Austin's Marine Science Institute show some important fish species are able to continue spawning even in a severe storm.

Being a marine scientist entails coping with extremes, from scuba diving deep in the ocean to interacting with living organisms that are among the planet's most mysterious creatures. Nonetheless, Hurricane Harvey was a whole new extreme for The University of Texas's Marine Science Institute. 

When Texas' worst drought on record hit the state between 2011 and 2015, it did more than dry up rivers and lakes. It changed the chemical composition of fish eggs, which revealed bigger changes to the marine life in Aransas Bay.

For more than 20 years, conservationists have been working to protect one of the most recognizable reef fish in the Caribbean, the endangered and iconic Nassau grouper, and thanks to those efforts, populations of this critical reef fish have stabilized in some areas. But in a new paper, published in the journal Diversity and Distributions, marine scientists said climate change might severely hinder those efforts by the end of this century.
