Populations of a picky species of Antarctic penguin have plummeted as a less-fussy species has prospered, showing that even closely related species respond differently to the effects of climate change.
New research reveals how penguins have dealt with more than a century of human impacts in Antarctica and why some species are winners or losers in this rapidly changing ecosystem.
Paul Miller, assistant professor and coastal meteorologist in the Department of Oceanography & Coastal Sciences, is using popular culture as an entry point by which his students can understand complex environmental interactions in a fun and meaningful way. In this fall's "Modelling the Marine Atmosphere"course, he taught students how to run a meteorological modelling experiment based on the movie, "Frozen."
Most people love to drink beer while enjoying the beach or while relaxing on a boat. It is one of the pleasures of life that you can enjoy year-round. The downside of this is cracking open a cold one is that the plastic packaging rings that are used to hold your beers together can harm marine life and wildlife and it can choke seabirds.
As an atmospheric scientist, I find that the public is often confused about concepts that seem very natural to me. Let’s face it, most people are not atmospheric scientists. I certainly cannot recite the key elements of a nuclear reactor because it is not what I do. It is understandable that it may be counterintuitive to some people that
For years, LSU sororities and fraternities have teamed up to create boards of painted pictures made out of rolled tissue paper.
Summer has begun to set in the northern hemisphere and is just beginning to peek through to the southern one. As our population continues to boom and our summers get hotter, more people than ever before are heading to the ocean to cool down. And what lives in the ocean? Sharks.
DALLAS – (Sept. 26, 2019) Today, the U.S. Environmental Protection Agency’s (EPA) Gulf of Mexico Division announced the Louisiana State University (LSU) College of the Coast & Environment as a 2nd Place Gulf Guardian winner for its EnvironMentors program to encourage interest in environmental stewardship and science careers among high school participants.
PEOPLE WHO ARE fascinated by nature and passionate about conservation may want to consider studying environmental science.
In the past few weeks, many of the politic-savvy professors that we've interviewed have pointed out climate change and environmental regulation as being hot-button topics in today’s political climate.
Hurricanes have great impact on land but they can be equally as destructive to aquatic environments, according to the National Oceanic and Atmospheric Administration.
The federal government's effort to avoid a flood disaster in New Orleans had catastrophic consequences of its own, causing massive fish kills and habitat destruction along the Gulf Coast, according to the governors of Louisiana, Mississippi and Alabama.
A data-gathering sensor attached to the American Queen steamboat will give scientists and cities a better understanding of water quality along the entire length of the Mississippi River, officials said Monday.
The National Science Foundation announced last week that it would pay for a $106 million boat to help scientists explore some of the critical issues affecting the Gulf, including climate change, hurricanes, fisheries' health and oil pollution. At 199 feet long, it would be the largest vessel devoted to scientific research in the Gulf region.
For the Grand Isle Tarpon Club, reeling in that next big fish is about a lot more than simply baiting a line and casting it into the Gulf of Mexico. The group of about 75 hardcore local anglers are teaming up with LSU and Mississippi State to study the migratory patterns of their namesake fish through a tag-and-release program that uses satellite tracking to see where the tarpon are coming from and going. It’s a new merger with science and the traditional fishing tactics that the group hopes will keep the sport going through the next generation. “We want to keep the tradition going. This is great for Grand Isle,” said club member Jeff DeBlieux, of Houma. “But we also want to preserve the fishery for our kids and everyone else and learn as much as we can about the tarpon.”
24 finalists advance in National Geographic and Sky Ocean Ventures’ Ocean Plastic Innovation Challenge
National Geographic and Sky Ocean Ventures launched the challenge in February 2019, which focuses on three strategic ways to address the growing issue of plastic pollution: identifying opportunities for industries to address plastic waste throughout supply chains, communicating the breadth of the issue through data visualization, and designing alternatives to single-use plastics.
Record-breaking spring rains and historic flooding in the Midwest were poised to create one of the biggest dead zones on record in the Gulf of Mexico this summer, researchers had estimated. Instead, Hurricane Barry mixed up the waters, making the dead zone smaller than expected, scientists said during a National Oceanic and Atmospheric Administration press conference on Thursday.
Fresh water from the Midwest floods has poured through the Bonnet Carre Spillway, 30 miles west of New Orleans, into southeast Louisiana and Mississippi this year. The spillway is a relief valve used to prevent local flooding.
From a puddle in the parking lot to the water in the area’s main drinking-water source, Bayou Lafourche, local scientists say microplastics are everywhere -- and they’re not leaving any time soon.
Divers monitoring coral reefs off St. Thomas in the U.S. Virgin Islands in January noticed something alarming: Big white lesions were eating into the colorful tissues of hundreds of stony corals. Some corals were dead by the next day — only their stark white skeletons remained. Others languished for up to two weeks. Within four months, more than half of the reef suffered the same demise.
Pollutants from booming farms combined with record wet weather are contaminating the nation's mightiest waterway.
The Mississippi River is trying to change course into the its historic Atchafalaya Basin channel according to Dr. Jun Xu, a world-renowned hydrologist and Professor of Hydrology at Louisiana State University’s School of Renewable Natural Resource, in a recently released video on Bigger Pie Forum. A course correction Xu says is not a matter of “if” but “when”, placing Southern Louisiana on the verge of one of the worlds most detrimental natural disasters in history.

Restore the Mississippi River Delta, a coalition of groups looking to slow that trend, recently took First Alert Storm Team’s Dr. Steve Caparotta up for a bird’s eye view of the fight to save our coast. Flying over the Mississippi River Delta, it can be tough to distinguish where the coast ends and the Gulf of Mexico begins. Our coast was built and shaped over the course of thousands of years, largely by natural meanders in the Mississippi River and its periodic floods that would deposit land-building sediment, but man changed that in the 20th century.

“I'm an ecologist and that basically means I'm someone who studies the interactions that organisms have with each other and with their environment. And the interaction I focus on the most is diets—who eats who. That's everything from understanding a species—how they find their food and what types of food they eat—but also looking across multiple species to understand how energy gets from the bottom of a food web all the way to the top.
Shark attacks have increased around the globe over the past 55 years, but that doesn't mean you need to cancel your beach vacation, according to a new study. The actual attack rate is low, and the risk varies, depending on your location. Researchers used data gathered from 1960 to 2015 from the Florida Museum of Natural History's International Shark Attack File for a worldwide statistical analysis of shark attacks.
Researchers at Louisiana State University have conducted the first statistical analysis of shark attacks worldwide using data collected over a 55-year period from 1960 to 2015. The experts found that even though the number of shark attacks has increased over time, the risk of shark attacks remains low.

Louisiana State University wetlands scientist Eugene Turner believes he has a simple solution for a key cause of coastal wetland loss in Louisiana: rake the dirt piled on the banks of canals leading to plugged and abandoned oil and gas wells back into the canals and allow nature to restore their wetlands.
SATELLITES WATCH MANY things as they orbit the Earth: hurricanes brewing in the Caribbean, tropical forests burning in the Amazon, even North Korean soldiers building missile launchers. But some researchers have found a new way to use satellites to figure out what penguins eat by capturing images of the animal’s poop deposits across Antarctica.
LSU Boyd Professor of Oceanography and Coastal Sciences R. Eugene Turner has determined a cost-effective way to prevent coastal erosion and protect Louisiana's wetlands. Along with LSU alumna and now University of Central Florida Postdoctoral Fellow Giovanna McClenachan, Turner proposes a simple and inexpensive way to fill in canals that were once used for oil and gas mining. Their research was published recently in the journal PLOS ONE.
State officials have embarked on a coast-wide effort to partner with the commercial and recreational fishing industry to find ways to make fishing more sustainable in the future, even as some state projects aimed at restoring coastal wetlands and land threaten fisheries and fishers.

Outdoor air pollution is a major environmental hazard affecting human health across the globe. The link between inhalation of ambient particulate matter (PM) and various adverse health effects is documented extensively by epidemiological and toxicological studies. Large fractions of ambient air PM originate from combustion and thermal sources, where at low temperatures at the end of the process, interaction of products of incomplete combustion with transition metals form environmentally persistent free radicals (EPFRs). These are identified as crucial PM components triggering hydroxyl radical (•OH) generation via EPFR redox cycle
