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 FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). […]
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 FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work in […]
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 […]
Go Green for Earth Day!
Do Mother Nature a solid with these helpful tips & tricks to go green today! Brittney G. BorowiecBrittney 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 […]
A Million Little Pieces….of plastic
Trillions of tiny plastic fragments are floating in the Earth’s ocean. These microplastics can attract organic pollutants, be ingested by marine organisms, and even end up in table salt. This Earth Week post gives a broad introduction to microplastics and examples of how we can all help to reduce this problem! Kari St.LaurentI received a […]
Blue New Year’s Resolutions
New Year’s resolutions are a great way to work towards being the person you want to be. This year, why not be a little bluer? Along with the rest of the Oceanbites writing crew, I’ve put together a list of suggested New Year’s resolutions that positively impact our troubled oceans, along with links to posts […]
Please Pass the Plastic
Tiny shards and fibers of plastic termed “microplastics” accumulate in seafood with unknown consequences for human health. Now, they’re turning up in a product even more difficult to avoid: Researchers in Shanghai recently found microplastics in table salts bought from supermarkets across China. Carrie McDonoughI am the founder of oceanbites, and a postdoctoral fellow in […]
Plankton are eating plastic!
Zooplankton, the tiny animals that make up the base of marine food webs, are ingesting microplastics. Given the widespread abundance of microplastics in the ocean, this finding could have serious ramifications for zooplankton and their predators. Sean AndersonI am a first year MS candidate at the University of Rhode Island, Graduate School of Oceanography. I […]
Wake-up Call: Global Oceans in Big Trouble!
Our global oceans are in a state of crisis. A new report from the WWF paints a bleak picture: human interference has pushed the oceans to the brink of collapse. The health of marine organisms and the habitats they live in have become severely threatened by compounding factors such as pollution, overfishing and increased CO2 […]
Tiny ocean creatures play a big role in the global fate of toxic pollutants
Scientists on the “biggest ever expedition on global change” studied the tiniest creatures in the ocean to learn about their role in accumulating and distributing toxic pollutants in the world’s oceans. Carrie McDonoughI am the founder of oceanbites, and a postdoctoral fellow in the Higgins Lab at Colorado School of Mines, where I study poly- […]
The Secret’s in the Slime
Scientists have recently discovered that the hagfish’s notorious slime has uses beyond defense: it also mediates uptake of toxins through the hagfish’s skin. Carrie McDonoughI am the founder of oceanbites, and a postdoctoral fellow in the Higgins Lab at Colorado School of Mines, where I study poly- and perfluorinated chemicals. I got my Ph.D. in […]
Out of sight, out of mind: The effect of gas & oil spills on deep-sea communities
When undersea wells blowout, toxic concentrations of hydrocarbons can be rapidly released into the environment. The media presents these blowouts with dramatic images of flora and fauna covered in black tar along coastlines and on the sea surface. What are rarely shown in glossy photographs, however, are the consequences to the unseen deep-sea. Sarah FullerWith […]
Corals consume microplastics! Talk about an unhealthy diet!
The dangerous diet fad among marine organisms is spreading! New study shows corals consume microplastics. Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work in southwest Florida, contributing to the management of an estuary. I am fascinated by the wonders of nature, […]
We Don’t Know the Half of It: Hundreds of Contaminants in Dolphin Blubber from Southern California
Dolphins and humans are continuously exposed to low levels of various halogenated, persistent manmade pollutants through their diets. In this study, blubber samples from 8 dolphins were analyzed by cutting-edge techniques to find out what’s accumulating in these marine predators. Findings suggest many routine monitoring programs underestimate the exposure of marine mammals to toxins. Carrie […]
Measuring “Roundup” in the Great Barrier Reef
Scientists estimated the degradation time for glyphosate, an herbicide in “Roundup”, in the Great Barrrier Reef. This is the first study of the persistence of glyphosate in seawater. Lis HendersonI am studying for my doctoral degree at the Stony Brook University School of Marine and Atmospheric Sciences. My research addresses fisheries and climate change in […]
Cartilaginous Conundrum: Are Sharks and Skates Safe to Eat?
While smooth dogfish may not be on your list of favorite seafood, cartilaginous fish (mainly sharks and skates) may increasingly find their way onto your dinner plate due to the decline of more traditional fisheries. While increased demand for these species as a food item could help struggling seafood industries, recent proposals to use dogfish […]
Why Do Sea Turtles Get Tumors?
Large numbers of green sea turtles are growing tumors that impede their swimming, block their sight, and prevent them from feeding. Researchers know that the tumor-causing disease, fibropapillomatosis, is more prevalent in some areas than others, but no one knows why. In this study, scientists set out to determine whether exposure to chemical pollutants may […]
