A blanket of oil: the role of bacteria in cleaning up after Deepwater Horizon
Nearly one million barrels of oil landed on the seafloor after the Deepwater Horizon spill – a feast if bacteria are able to consume it. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, […]
Sea snakes join the dark side to cope with pollution
Black sea snakes are more common in contaminated sites. Why? 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 (diurnal) patterns of hypoxia.

Small MPAs: the new all-you-can-eat buffets?
Marine Protected Areas (MPAs) are a popular conservation tool and are in many situations very effective. Unfortunately, as with many plans, there may be some unintended consequences, as seen in the case of small MPAs in Fiji, where they appear to have attracted corallivorous crown-of-thorns sea stars (Acanthaster spp.). Find out more in today’s oceanbites! […]
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.). […]
If You Must, Adjust? Polar Bears Leaving Sea Ice in the Arctic
Everyone knows that polar bears have become the poster children for species threatened by climate change. And it’s for good reason that they are. Polar bears rely on sea ice for access to prey, finding mates, and creating dens. The persistence of the species depends on the state of sea-ice and more generally a healthy […]
Changing with the environment: how resilient are coral reef fish?
Coral reef fish are some of the most sensitive animals to climate change. How will coral reef fish respond to predicted increases in temperature and carbon dioxide? Do they have the ability to adapt to future conditions or is it already too late? Sean AndersonI am a first year MS candidate at the University of […]
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 […]
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 […]
Oceanbites at the Society for Integrative and Comparative Biology: Part II
This year’s annual meeting for the Society of Integrative and Comparative Biology brought together over 2000 scientists to share their research. With a slew of exciting topics ranging everywhere from ecology to biomechanics, there were plenty of talks worth reporting. But, for the second post on SICB, I will share my most memorable marine talks. […]
Trawling selects for faster fish
A new study suggests that differences in exercise performance make some individuals more vulnerable to capture by trawling than others, and that this may drive the evolution of commercially-important fishes (Photo: Wikimedia). Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses […]
Small boats drowning out natural reef noise?
Don’t you hate when noises interfere with your daily activities and conversations? We create lots of noise in the environment and need to know more about it. Today’s oceanbites focuses on a study of man-made noise on coral reefs. Check it out! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and […]
Making potable water safe for the seafloor
SWRO desalinization is a great way to get potable water. Unfortunately its production results in a high salinity low nutrient discharge that impacts the benthic communities. This study shows how a simple mitigation effort can reverse damage from discharge in just months! Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m an earth […]
Sound waves: dolphins in a noisy ocean
As human influence in Earth’s oceans increases, so does the background noise. How might dolphins cope with changes in environmental noise levels, particularly in areas where it has seen a substantial, recent increase? Do chattier dolphins have to invest more energy into their aural physiological systems? Brittney G. BorowiecBrittney is a PhD candidate at McMaster […]
Carbon sinks: Diatoms in the deep sea
Fast-sinking phytoplankton particles deliver carbon from the surface to the deep ocean. Are plankton cells still able to survive when they sink to the deep ocean? If so, how long may they survive without any sunlight? Sean AndersonI am a first year MS candidate at the University of Rhode Island, Graduate School of Oceanography. I […]
Tiny plastic pieces accumulate in a huge marine filter-feeder
Scientists find microplastic pieces in the intestines of a baleen whale for the first time. 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 the Northwest Atlantic. In my free time, I like to cook and spend […]
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 […]
Are Fisheries Scientists Ringing the Dinner Bell for Marine Mammals?
Acoustic telemetry is a valuable technique used by fisheries scientists to track fish movements. However, a new study suggests that these anthropogenic signals may make tagged fish an easy target for marine mammal predators like dolphins and seals. Derrick AlcottDerrick is pursuing a Ph.D. in the Organismic and Evolutionary Biology Program at the University of […]
The Great Barrier Reef is worth $15 billion – $20 billion AUS a year: A quick lesson in ecosystem economics
When discussing the value of an ecosystem, tensions run high. Some people evaluate ecosystems with heavy emphasis on non-use values, like aesthetics and spiritual appreciation. Other people value ecosystems based on things like natural resource availability and the potential for direct monetary revenue. It is difficult to assess the relative importance (or value) of these […]
