The Gulf of Mexico Triangle: Assessing Movements of Large Pelagic Fish Across Multiple National Boundaries
Pelagic predators or difficult to manage due to their vast migrations through through multiple countries jurisdictions and international waters. In order to effectively manage these species multinational agreeements are required. However, collecting movement data for species that travel long distances is difficult to collect. Here, researchers look at the movements between countries of 8 species […]
In the hot seat: Hot spots for pelagic shark movement reflect hot spots for commercial longline fisheries in the North Atlantic.
Check out the latest from Matt Larsen about shark habitat around the globe, and how these areas overlap with fishing hotspots! Matthew LarsenI am a second year master’s student at Coastal Carolina University in the Abel Lab. My interests focus on the ecology and life history of large marine megafauna with a central focus on […]
Lost in the sound: coral planulae habitat selection affected by boat noise
It can be hard to cut through the noises that surround us and focus on the task in front of us, right? This may not just be a human problem. Noise pollution may be another way human activity is negatively affecting corals. Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and […]
Oceanic Outlook in the New Government Climate Report
Ocean warming, acidification, sea-level-rise, and increased coastal storm intensities are just some of the stark projections highlighted in a recently-released U.S. Government climate report. Zoe GentesZoe has an M.S. in Oceanography and a B.S. in Geologic Oceanography from URI, with a minor in Writing and Rhetoric. She was recently a Knauss Marine Policy Fellow in […]
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.
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 ZinkeI am a PhD student […]
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 GangulyI’m a fourth year PhD candidate in the Department of Psychology at Northeastern University. My […]
New Nitrogen in Town: Nitrogen Deposition on the Open Ocean
Life in the ocean depends on a variety of nutrients, an important one being nitrogen. Phytoplankton, at the bottom of the oceanic food chain, require it to photosynthesize. Burning fossil fuels releases nitrogen into the atmosphere, and a portion of it is known to settle into the ocean. Has the ocean started to show signs […]
Current connections: how far away coastlines influence marine reserves
A research team used a state-of-the-art model to map how four remote Marine Protected Areas are connected to the surrounding oceans, and how human activities are impacting them from afar. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s […]
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 TamsittI’m a PhD student at […]
Throwing Babies out with the Sea Ice: Ringed Seals Response to Ice Decline
As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I […]
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.). […]
Big animals face big trouble in our oceans
Many believe we are in the midst of another mass extinction both on land and in the ocean. What marine animals are most at risk of extinction? Using current and past extinction data, researchers were able to pinpoint the most vulnerable types of marine animals. Sean AndersonI am a first year MS candidate at the […]
Pet trout: domestication rapidly alters gene expression
The impact of domestication can be detected within one generation in steelhead trout, and may involve adaptation to highly crowded conditions. 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 […]
Ancient swimmers: Greenland sharks live for centuries
Using radiocarbon dating, scientists have discovered that the Greenland shark can live longer than any other known vertebrate. How long have some of these individuals been alive? Sean AndersonI am a first year MS candidate at the University of Rhode Island, Graduate School of Oceanography. I am interested in plankton ecology and the dynamics within […]
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 […]
Why don’t sharks go deep?
Happy Shark Week! Today we examine a persistent and interesting biogeographical puzzle: why are there so few deep sea sharks? 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 […]
Eavesdropping prawns get more than they bargained for
Marine animals living below the surface have to put up with noise generated by human activity. Heavy shipping traffic can bring a lot of noise. How does the common prawn respond? Sarah GiltzI am a doctoral candidate in Ecology and Evolutionary Biology at Tulane University. My research focuses on the larval dispersal and development of […]
