Noise Pollution Stresses Sea Urchins

You may have heard that marine mammals are affected by manmade ocean noise. But have you ever wondered whether smaller critters like sea urchins are impacted? A team led by Vazzana is the first to use coelomic fluid to assess urchin responses to noise. Constance SartorConstance is a graduate student at the University of Guam […]

If you can’t stand the heat, get out of the kitchen: An analysis of phytoplankton with changing ocean temperature

If you went to the beach and the water is cold, would you jump in? The same questions pertain to very small creatures called phytoplankton off the coast of Mexico. A group of scientists recently studied the behavior of phytoplankton as the ocean’s temperature due to large weather events like El Niño and found some […]

The Age-Old Question about Sea Turtles

There’s a lot that science has taught us about sea turtles – but we still don’t know how old these marvelous marine reptiles can get. A team of scientists turn to genetics to predict the answer.

Me, Myself, and I: The Solitude of Bacteria above the Southern Ocean

Picture this: shrink yourself down to the 1/1000th the size of the period at the end of this sentence. You are now the size of a bacteria. Due to your dimensions, you are so incredibly light (around 0.0000000000000000007 pounds) that the slightest wind could pick you up and move you around. Around most of the […]

Genetically Modified Yeast Can Clean Up Wastewater

Humans have been polluting the ocean with heavy metals by burning fossil fuels, mining metals and discharging wastewater. But we may be able to clean up metals from the ocean in the near future with yeast. Jiwoon ParkI am a PhD student in chemical oceanography at University of Washington. I am studying how different forms […]

East African Lake Fosters a Melting Pot for Cichlid Evolution

Darwin’s famed finches weave a tale of evolution in isolation. Joana Meier and her research team now find that evolution, specifically adaptive radiation, may not actually require such complete isolation to stimulate the creation of new species. Rishya NarayananRishya is a multimedia science communicator with an MS in Media Advocacy from Northeastern University, specializing in […]

Baby, you light up my world: Using genetics to understand how velvet belly lanternsharks produce light

Eat or be eaten is the way of the ocean, and many marine species have adapted ways to accomplish one while avoiding the other. The velvet belly lanternshark (Etmopterus spinax) is a small deep sea dogfish species found in the Northeast Atlantic Ocean. Lanternsharks get their name from their ability to light up like a […]

Are you feeding your pet endangered sharks?

Did you know there could be shark in your dog or cat’s food? Did you know they could also be in your beauty products? Now that you’re back from reading your product labels, I’ll tell you the bad news. They might be there even if it isn’t on the label. Keep reading to learn how […]

How the anglerfish gets its light

Deep-sea anglerfishes are known for their prominent glowing lure extending from their heads. Bacteria are behind the scenes, enabling anglerfish to create their bioluminescence. How and when do anglerfish form the bond with their bioluminescent bacterial partners? Scientists may now have an answer. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island […]

Skin that Sees: Evolution and Mechanism of Phototaxis in Sea Snake Tails

Researchers have discovered light sensing abilities in the tails of sea snakes. This unique adaptation in one genus of snakes may allow them to sense and respond to impending danger. Crowe-Riddell, J. M., Simões, B. F., Partridge, J. C., Hunt, D. M., Delean, S., Schwerdt, J. G., … Sanders, K. L. (2019). Phototactic tails: Evolution and […]

The Coral Dilemma: Is Hybridization the Key?

Coral: a mineral, plant, and animal all in one (oh my!) Unfortunately, coral is in danger- and the many reefs which support a wide variety of organisms (including humans) are rapidly dying. Does interspecific hybridization hold the key to our coral dilemma? Rishya NarayananRishya is a multimedia science communicator with an MS in Media Advocacy from […]

Microbe Mishap: Microplastic Pollution on the Coast of China

Marine plastic pollution has vast negative effects on the environment and human health. Microbes on the plastic may be transferring disease-causing microorganisms around the ocean or reducing the plastic’s toxicity. Researchers studied these plastic associated microbes on the coast of Shanghai, China. LeAundra JeffsI am a Master’s Candidate at University of Delaware where I study […]

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? […]

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 […]

Now we got bad blood: Oxygen binding is not affected by haemoglobin subtype in Atlantic cod

Why do northern and southern populations of Atlantic cod have different haemoglobin subtypes? A recent study upsets over 50 years of theory. 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 […]

Swashbuckling spiders sailed the high seas

Long before the Vikings reached North America, a group of coastal spiders was already sailing around the world using prevailing winds, currents, and rafts. 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 […]

Parenthood: The Most Rewarding Experience or The Ultimate Sacrifice?

Our human parents make a lot of sacrifices for us! They devote their time and energy, provide for us, invest in us (monetarily, sure, but also emotionally), nurture us, attempt to teach us, make career decisions with us in mind, and lose a lot of sleep worrying about us. However, in the marine world things […]

You look like your mom: parental effects in Atlantic salmon

In honour of our Mother’s Day theme week, we’ll look at how the environment experienced by parents during reproduction and their early life history influences their offspring. 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 […]

A cod by any other name would taste as sweet?

Seafood is a staple of the American diet, particularly on the coasts. Distributors frequently mislabel seafood, accidentally or fraudulently, because seafood species may be difficult to tell apart after chemical and physical processing. We need a fast, reliable, and cost-effective way to accurately identify seafood species in order to reduce fraud. This paper presents a […]
