Plastics increase disease risks for corals

You have probably heard about the troubles coral reefs are facing and about the detrimental effects of plastic pollution in our oceans. Now these two issues appear to be linked: corals are getting sick when they come in contact with plastic. Find out more here. Ashley Marranzino I received my Master’s degree from the University […]

Sea snakes join the dark side to cope with pollution

Black sea snakes are more common in contaminated sites. Why? Brittney G. Borowiec Brittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and metabolic responses of Fundulus killifish to intermittent (diurnal) patterns of hypoxia.

Crude oil cripples sandpiper flights

Maggini, I., L.V. Kennedy, A. Macmillan, K.H. Elliott, K. Dean, and C.G. Guglielmo. 2017. Light oiling of feathers increases flight energy expenditure in a migratory shorebird. J. Exp. Biol. 202:  2372-2379; doi: 10.1242/jeb.158220. The Deepwater Horizon oil spill On the evening of April 20th 2012, an explosion on the Deepwater Horizon oil drilling rig rocked the Gulf […]

Paper or plastic? Policies inspired by research to find a solution to plastic pollution

Paper or plastic? In a lot of grocery stores, this is an innocent question, but recently it’s become a controversial issue. We talk about how plastic pollution research has inspired a barrel of policies, and some of the creative new ways people are trying to clean up the earth! Laura Zinke I am a PhD […]

Seaweed antioxidants protect fish too

A new study suggests that feeding fish small amounts of antioxidant-rich seaweed can protected them from environmental challenges. Brittney G. Borowiec Brittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and metabolic responses of […]

Fireproofing the Arctic

Chemicals that are stable enough for our everyday use are often remarkably stable in the natural environment as well. This poses a problem because these chemicals can travel far from sources and end up in pristine environments like the Arctic. In the study described here, researchers from Germany and China joined forces to measure one […]

BAD BOYZ 2.0. Emerging environmental contaminants

Our generation is facing environmental challenges not only from commonly-known contaminants, but also emerging ones, which have been lurking in the shadows until recently. Check this week’s post to know more about these (sometimes surprising) pollutants, and their effects! Prabarna Ganguly I’m a fourth year PhD candidate in the Department of Psychology at Northeastern University. […]

The oil droplet is quite terrified

Oil Spill Snorkels: Eating oil, breathing electrons, saving the world?

Oil spills are not great for the environment, but some bacteria thrive on eating oil. Scientists have been researching ways to use these natural oil degrading bacteria to clean up oil contaminated areas. A group in Italy adapted graphite rods to encourage marine mud bacteria to degrade oil more quickly. They call this the “Oil […]

After the Phase Out: Can Banning Toxic Chemicals Rescue Pilot Whales?

When it comes to persistent pollutants, all roads lead to the ocean. Perfluorooctanesulfonic acid (PFOS) is a chemical that has recently gained attention due to its toxic effects and widespread presence in drinking water. PFOS from human products has also become widespread in ocean waters and the creatures who live in them. PFOS was banned […]

I’m Gonna Soak Up the Sun: Sunscreen’s Impact on Coral Communities

Sunscreen prevents skin cancer but may also be linked to coral bleaching and harm to coral larvae. Read more to find out what scientists found in corals off the coast of Hong Kong when they sampled for common sunscreen UV protection chemicals. Victoria Treadaway I am a PhD candidate at the Graduate School of Oceanography […]

The end of the line for ocean plastics

A team of researchers set out on an Expedition around the Arctic Ocean to prove what scientists have long suspected: plastic debris is carried by ocean currents to a far corner of the Arctic Ocean where it reaches a dead end and is causing a massive plastic pile up. Veronica Tamsitt I’m a PhD student […]

MARPOL-ling in the Right Direction

What Does the US Election Mean for Our Oceans?

The oceans are subject to the whims of national policy, and yet they know no borders. Being poor ocean stewards here in the US could cause serious problems all over the world, as well as affecting the smidgeon of blue we can see from our shores. In this post, I outline a few ideas about […]

Microbes: The original organic cleaning agents

Natural and human caused leakage of oil into the environment is commonplace throughout the world. Scientists are learning how microbes (microscopic organisms) can break down this oil and use it for energy. By understanding these processes, we will be able to determine the short and long-term environmental impacts, as well as use these organisms to […]

Let’s Ghost Fishing for Halloween!

Ghost fishing is ghastly because it creates underwater graveyards for wildlife. The authors covered here wrote a new review of gear entanglement among mammals, reptiles, and sharks. Find out what they discovered by reading today’s post! Rebecca Flynn I am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island […]

Beyond CO2: Chemical Consequences of Our Love Affair with Fossil Fuels

Our world relies heavily on the burning of biological materials such as wood or fossil fuels to harness energy. While we all know that carbon dioxide (CO2) is a harmful byproduct of burning fuel, it’s not the only chemical formed during this process. These chemical byproducts may play a bigger and more complex role in […]

Coral Microbiome Health: There’s no probiotic yogurt for that

Coral reefs are essential to the overall health of the planet. Comprised of tiny, individual animals, these massive ecosystems contain as much biological activity as that of human crop production. By studying the microscopic organisms living within these corals, scientists can predict when a reef may be under threat from serious diseases before it is […]

To I.D. Debris: LIDAR as a tool to identify trash on the beach

Scientists may have a new option for figuring out how much debris litters our beaches and what it all is! Find out more in today’s World Oceans Day post on marine debris! Rebecca Flynn I am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work […]

What’s in the Hair of a Polar Bear?

The accumulation of toxic methylmercury is a serious threat to wildlife all over the world – especially top predators in polar regions, like polar bears. Young polar bears are often the most vulnerable to detrimental effects of pollutants. To learn more about levels of mercury in polar bear cubs and their mothers, scientists measured total […]
