Wake up and smell the marine awareness…on social media?!
Close your eyes and imagine your favorite beach, or a memorable coast you have visited, completely free of litter-that’s right, no plastic bottles, no garbage, no microplastics, no wandering potato chip bags. Is this vision possible? Take a moment, or 3, and see what you can do to reduce marine pollution!

Close your eyes and imagine your favorite beach, or a memorable coast you have visited, completely free of litter-that’s right, no plastic bottles, no garbage, no microplastics, no wandering potato chip bags. Is this vision possible? Take a moment, or 3, and see what you can do to reduce marine 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!
Social science has shown that too much doom and gloom about the ocean and other environmental issues is depressing. So how do we empower more people to take action? An appropriate dose of optimism!
Seabirds and invasive species have been a poor mix for centuries, yet new research suggests seabird populations are bouncing back from invasive species damage. Read on to hear about seabird success following invasive predator removal on islands across the globe!
: Iron isn’t just good for your body – it’s good for the ocean, too. While many studies focus on external sources of iron to the global ocean, Fitzsimmons et al. investigated iron sources coming from deep hydrothermal vents along midocean ridges, and how they might disperse iron and other metals vast distances through the ocean.
Save the whales… save the ocean… but save the sharks? This is a mission that is still new, and often surprising, to many. The Atlantic White Shark Conservancy is working hard to conserve white sharks specifically, and in doing so has learned that they have to work to change public perception of this critically important apex predator.
Before the late 20th century, reports of illness from toxin-producing algae had been absent from most northern coastlines. But in the past 30 years, the incidence of algae-related poisonings in humans have been increasing in areas such as the U.S. Pacific Northwest and the United Kingdom. By modeling harmful algae growth in the North Atlantic and Pacific, Gobler et al. show which change in ocean conditions is responsible for these new harmful algae outbreaks.
The regional impacts of ocean acidification are unclear. Researchers measured pH in the intertidal waters off the western coast of the United States. Read more to find out if the water pH was consistent along the coast and whether it is higher or lower than the global average pH of 8.1.
As the planet warms, Antarctic land ice is retreating rapidly in some regions, and along with this, small pockets of ice-free habitat are growing and connecting. A team of scientists predicted how much these ice-free regions will expand by the end of the century and what this means for Antarctica’s unique ecosystems.
Human created chemicals can be “too good” at their job, remaining persistent and/or toxic in the environment, well beyond the life span of their commercial use. Read on to explore how DDT was found at depths up to 2500 m in the Arctic Ocean by a team from Stockholm University.
Oreska MPJ, McGlathery KJ, Porter JH (2017) Seagrass blue carbon spatial patterns at the meadow-scale. PLoS ONE 12(4): e0176630. https://doi.org/10.1371/journal.pone.0176630 Plants take in carbon dioxide as part of their normal functioning, to create carbon-based sugars for food. When they die, that carbon is decomposed in the soils or sediment and, eventually, released back to the […]

A new study suggests that feeding fish small amounts of antioxidant-rich seaweed can protected them from environmental challenges.
Hydrothermal vents are hot, dark, and toxic environments. But to sulfur oxidizing bacteria, they’re home.
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 group of manmade molecules, the organophosphate esters, in snow, seawater, and air from the remote North Atlantic and Arctic Ocean.
Welcome to oceanbites!
The goal of oceanbites is to make cutting edge research in the ocean sciences accessible to all. oceanbites will also highlight classic, seminal research papers, and feature op eds about current issues in research.
