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 […]
Stuck in the middle with you: The trophic ecology of Caribbean reef sharks and large teleost coral reef predators
We often think of sharks as the top of the ocean food web, chowing down on seals and big fish to their heart’s content. That is often not the case! Where does the Caribbean reef shark fall in this hierarchy? Let’s find out. Grace CasselberryI am currently a Marine Science and Technology Doctoral student at […]
Citizen Science and Undersea Stars: The Value of Photographs to Global Megafauna Biology
Check out this article about how tourist pictures of whale sharks are helping scientists learn about whale shark populations around the globe! 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 […]
Danger in the deep: uncovering the vertical movement patterns of vulnerable deep-sea sharks
Deep-sea sharks are one of the most poorly studied groups of animals on the planet, yet, their populations are highly threatened by fisheries bycatch. Scientists in The Bahamas develop new field approaches to begin unearthing the vertical movements of a vulnerable deep-sea shark, the Cuban dogfish, and their findings from could help significantly reduce fisheries […]
Coming Home to Roost: A case of parasites relying on ancestral DNA to take advantage of a new penguin host species?
Parasites are nasty and resilient organisms, often highly specialized to fit their hosts. But sometimes, nature allows a bit of wiggle room, opportunity strikes, and new species find themselves vulnerable to these unwelcome houseguests. This could be what has happened to Magellanic penguins. Curious to learn more? Click here! Andrea SchlunkI am a former PhD […]
Melting ice, shifting microbes
Polar bears have been the poster child for sea ice melting in the Arctic. But what does sea ice loss melt mean for the Arctic’s most numerous members – its microbes? Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes […]
Invasive seagrass changes fish community in the US Virgin Islands
Seagrass meadows provide food and habitat for a variety of fish species. Juvenile fish are particularly dependent on the meadows, for the shelter they provide from predators. In the Caribbean, several native seagrasses might be found in the same shallow estuary or coastline, forming a patchwork of meadows that support a variety of different fish […]
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, […]
Riding the phage wave: Emerging role of viruses in the ocean
Viruses live in the ocean, where they infect bacteria who also live in the ocean. Ocean viruses are crucial to the ecosystem, but we don’t know very much about how they ‘survive’ in the ocean. Scientists used data from samples collected all over the world, and explored what types of viruses were in these samples. […]
The answer to starvation? Diversity
Photosynthetic microorganisms can’t go it alone, so they succeed by playing host to a diverse array of microbial partners 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, and what are they doing there?

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.
The elephant in the oxygen minimum zone
When people think of the animals that inhabit the deep sea, they think of the fascinating, alien-like creatures like the anglerfish or the colossal squid. But, there are other animals that are able to inhabit parts of the deep ocean for a short amount of time, like the elephant seal. Why do they go down […]
The ocean’s tiny, mysterious majority
The earth has more viruses than the universe has stars – but we know far less about our tiny majority at home than we do about the glowing balls of gas in our night sky. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why […]
Toxic living: finding the right home for sulfur-oxidizing bacteria
Hydrothermal vents are hot, dark, and toxic environments. But to sulfur oxidizing bacteria, they’re home. 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, and what are they doing there?

Stressed-out microbes in an acidifying ocean
The ocean is acidifying in response to carbon dioxide emissions, but we are just beginning to learn how this effects the ocean’s most abundant lifeforms – microbes.

TBT Old School Ocean Tech: Simple Sampling Gear
Sometimes it’s the simple things in life that make it all worth it! Well, it may just be me, but I love using the tried and true old school sampling gear, despite all the complex gadgets and gizmos that seem to be developed faster than I can learn about them. In today’s ocean tech post, […]
Red dead algae
Life on earth has been evolving for a long time – billions of years! The timing of when different kinds of life developed is controversial, but can tell us about the conditions of earth in the past. A group of scientists in Sweden looked at ancient fossils from India, and found what they describe as […]
Seagrasses reduce the risk of disease outbreaks
Seagrasses are one of humans’ greatest sidekicks. They are nursery areas for many species including commercially important ones, they protect coastal communities from extreme weather, they absorb carbon dioxide and release oxygen via photosynthesis and much more. Now, research shows that seagrasses can also reduce rates of disease in humans, fishes and invertebrates such as […]
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 […]
Ocean acidification makes predators dumb
Chemistry is important for a lot of things, but can it change the behavior of animals? Read on to find out how changes in water chemistry alter the behavior of a venomous cone snail!
