Facing the music: calls from one of the worlds most endangered dolphins

The Study: Melo-Santos, G., Figueiredo Rodrigues, A.L., Tardin, R.H., de Sá Maciel, I., Marmontel, M., Da Silva, M.L., May-Collado, L.J. 2019. The newly described Araguaian river dolphins, Inia araguaiaensis (Cetartiodactyla, Iniidae), produce a diverse repertoire of acoustic signals. PeerJ: e6670. https://doi.org/10.7717/peerj.6670   River Dolphins Inia araguaiaensis was first discovered in 2014 and is one of […]

Increasing resilience, one cannibal at a time

When a species invades a new habitat they must learn to cope with previously unknown environmental stressors. Read on for this species strange adaptation to survive the winter. Brandy BiggarI am a 2nd year Master’s student at the Memorial University of Newfoundland. I am researching the highly invasive species the European green crab, and the […]

How scientists use our nuclear past to understand whale shark life history

To properly conserve and manage species, scientists need to understand how they live, grow, and age. But even figuring that out can be difficult when they are large and elusive, like the whale shark. See how scientists can benefit from more tragic moments in our past and use the legacy of nuclear bomb trials to […]

Tough bugs below the waves?

Just as humans can build up tolerances to things we’re exposed to, so can bacteria. Introduce antibiotics to an ecosystem and it’s a fair bet local germs will take note. Tag along and learn what a group of scientists in Florida found after sampling the water we’ve flushed down the drains! Andrea SchlunkI am a […]

Sargassum: An Overlooked Solution

Sargassum, a type of brown seaweed, provides important ecosystem services in the Atlantic. However, this new study explores how sargassum may provide one solution to marine pollution. Ashley MickensI am a senior Environmental Earth Science and Sustainability major at Miami University of Ohio. While my undergraduate research focused on biogeochemical cycles in lakes and streams, […]

The HyperDiver: A New (Hyper-) Intelligent Way to Map the Ocean

German researchers have developed a new system–based on sophisticated imaging technology and artificial intelligence–which promises to revolutionize how we map coral reefs. Emily ChuaI am a Ph.D. candidate at Boston University where I am developing an underwater instrument to study the coastal ocean.  I have a multi-disciplinary background in physics and oceanography (and some engineering), […]

Changing Oceans May Confuse Critically Endangered European Eels

As humanity’s carbon emissions continue to heat and acidify the world’s oceans, many marine species and ecosystems face daunting new challenges for survival. Sierra GarciaSierra is a master’s student in Stanford University’s Earth Systems department studying science and environmental communication. Her bachelors degree was also in Earth Systems, with an emphasis on oceans and climate, […]

Follow the breadcrumbs: Sponges show how some animals clean up viruses

These days, hunkered down in our homes (if we are lucky) and washing our hands till they’re raw, it can feel like the outside world is a virus soup. However animals in the ocean go swimming through viruses on a daily basis. A new study from the Netherlands shows us that in fact many animals […]

Deep Breathing Underwater

The Labrador Sea is one of the lungs of the ocean. A new study finds that it is taking an even deeper breath than expected—making it more vulnerable to climate change than thought. Emily ChuaI am a Ph.D. candidate at Boston University where I am developing an underwater instrument to study the coastal ocean.  I […]

Blue Coral with a Not-So-Blue Future

Before this genetics study, we only knew of one extant octocoral species producing a massive skeleton. Not only does Iguchi’s study reveal speciation in blue coral, but it also suggests potential thermal resilience. Constance SartorConstance is a graduate student at the University of Guam studying coral genetics. She also paints murals integrating art and science […]

An Ocean on Fire

Heatwaves in Australia are stoking the flames of the wildfires currently ravaging the country.  While the effects are not as visible, the ocean, too, is suffering from extreme temperatures.  Recent research reveals that underwater heatwaves are escalating, with devastating impacts. Emily ChuaI am a Ph.D. candidate at Boston University where I am developing an underwater […]

Tagging the deepest diving mammal: the Cuvier’s beaked whale

A few years ago, the Cuvier’s beaked whale set the record as the deepest diving mammal. At the time, not much else was known about their diving abilities. Check out what Shearer’s team has done to study these elusive divers off the coast of North Carolina. Constance SartorConstance is a graduate student at the University […]

The secret life of cheese: how dairy can support biofuel production

Did you know that phytoplankton can be used for biofuels? They provide a good alternative to fossil fuels because they can grow very quickly and are rich in lipids and carbohydrates. Lipids are extremely rich in energy and carbohydrates can be converted to sugar which is then fermented to make fuel. In fact, a recent […]

Think global, act local: how lake microbes respond to their environments

How do microbes in lake sediments respond to small and large scale influences, and what does it have to do with climate change? Nyla HusainI’m a PhD student at the University of Rhode Island Graduate School of Oceanography. I use models to study how small-scale physical processes at the air-sea interface – like waves – […]

Farmed Kelp to the Rescue? Not So Fast, Say Researchers

Kelp farming is on the rise across Europe and North America, and all the headlines say that’s a good thing for fighting climate change. But scientists say we need to make sure kelp farms don’t spawn even more environmental problems.    Grebe, Gretchen S., Carrie J. Byron, Adam St. Gelais, Dawn M. Kotowicz, and Tollef […]

Jellyfish Blooms Could Increase the Risk of Bacteria-Spread Illnesses in Humans and Marine Animals

Happy Thanksgiving! With Black Friday right around the corner, it might be surprising to hear that humans aren’t the only species that swarm to certain areas. Ashley MickensI am a senior Environmental Earth Science and Sustainability major at Miami University of Ohio. While my undergraduate research focused on biogeochemical cycles in lakes and streams, I […]

Hidden diversity in ships’ ballast tanks

Did you know that organisms can live in the ballast tanks of cargo ships? Ballast tanks are used by ships to maintain stability as they transverse across ocean basins. Unfortunately, ballast water is a major culprit of the introduction of invasive species worldwide. Read on to learn more about a recent study that uses genetic […]

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 […]

Clinging, cloning jellyfish: How an old species is coming back with new force

On the fourth of July, 2019, happy beach-goers in Rhode Island escaped the directness of the sun by wading into Point Judith Pond. For an unlucky few, this small pleasure turned out to be immensely painful. By July 5, people were being warned about clinging jellyfish. What was this new threat to unsuspecting swimmers? Turns […]
