Time to rethink the role of ocean’s microbes?

Have you ever wondered what may live inside the tiniest drops of seawater? Global oceans are dominated by organisms we cannot even see. Marine microbes are resilient, incredibly diverse, and ecologically important. These microbes deserve a closer look. Sean AndersonI am a first year MS candidate at the University of Rhode Island, Graduate School of […]

Clams Catch Contagious Cancer

Clams along the northeastern coast of North America are suffering from a form of cancer that researchers have recently discovered is a new type of contagious cancer. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology of deep-sea fishes. I am now working with the South […]

Leaving the nursery: fish migration between juvenile and adult habitats

Many fish utilize different habitats as adults than they do as juveniles, but little research has shown how they make the shift between the two habitats. This recent study did just that using acoustic tags! Read to learn more! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of […]

Epic: sperm whales hunt squid

Bad environmental news can seem overwhelming at times. No matter how environmentally aware you are, you will still need to eat something and you will take up space that probably used to belong more to nature than it does now. So let’s take a moment to appreciate why it’s worth trying to conserve nature. Let’s […]

The Advantages of Being a Deceptive Fish: Tales of a Predatory Mimic

Dusky dottybacks are small (8cm/3in) fish found on the Great Barrier reef, but despite their small size, they are fish eating predators feasting on up to 30 juvenile damselfish per day. Dottybacks are able to be so successful at capturing their prey by being masters of deception thanks to their “phenotypic plasticity.” Derrick AlcottDerrick is […]

Hail and Tornadoes? Blame ENSO

El Niño/Southern Oscillation (ENSO) can change winter weather on the western coasts of South and North America. Its arm of influence extends to the interior of the US as well, and can affect the frequency of severe weather events such as hailstorms and tornadoes throughout winter and spring. Zoe GentesZoe has an M.S. in Oceanography […]

Sea urchins work harder, faster to cope with ocean acidification

The ability of sea urchins to withstand ocean acidification comes at a hidden cost. Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.

Cooling in North Atlantic Defies Global Warming

Sluggish ocean circulation can’t keep up with global climate change and this has caused the North Atlantic to cool. Hillary ScannellHillary received her MS in oceanography from the University of Maine in 2014 and works in the Ecosystem Modeling Lab at the Gulf of Maine Research Institute in Portland, ME.

The Secret’s in the Slime

Scientists have recently discovered that the hagfish’s notorious slime has uses beyond defense: it also mediates uptake of toxins through the hagfish’s skin. Carrie McDonoughI am the founder of oceanbites, and a postdoctoral fellow in the Higgins Lab at Colorado School of Mines, where I study poly- and perfluorinated chemicals. I got my Ph.D. in […]

Just sealing around; Ice seal misidentification in aerial surveys

Aerial photographs are a great way to collect images of marine species in order to analyze their distribution patterns. Distinguishing different species is difficult, and unfortunately this leads to the misidentifictation of several species. This is the case for ice-associated seals, species for which global climate change has motivated intensive monitoring efforts in recent years. […]

Fizzing glaciers are louder than you’d expect

While anthropogenic noise pollution has been gaining a lot of attention, there is still much to be learned about ambient ocean noise. A team of researchers found that glaciers create some of the loudest noises in the ocean, with evolutionary implications for marine organisms living near glaciers. These findings elucidate the nature of ambient, natural […]

Lethal Injection: Crown of Thorns Edition

Predation by crown of thorns sea stars (COTS) is one of the main causes of coral reef decline in Australia’s Great Barrier Reef. Death by injection of sodium bisulfate is the most commonly used method, but this requires COTS to be removed from the reef and injected many times. Is there a better way? Read […]

Blooming around the world: A story of coccolithophore co-existence

Satellite remote sensing suggests that different phytoplankton species can live in harmony during phytoplankton blooms in the open ocean. Kari St.LaurentI received a Ph.D. in oceanography in 2014 from the Graduate School of Oceanography (URI) and am finishing up a post-doc at the University of Maryland Center for Environmental Science (Horn Point Laboratory). I am […]

Cetacean avoidance? They’re doing it on porpoise

Dolphins aren’t always fun loving and gregarious like Flipper. In fact, they often act like bullies. Dolphins show aggression towards other marine species, even their close relatives, porpoises. Off the coast of California, harbor porpoises have had enough, and have started actively avoiding dolphins. Read on to find out more! Gordon OberPostdoctoral Researcher, Claremont McKenna […]

One fish, two fish, small fish- don’t fish!

Fishery management is complicated, but important. Read more about one way to protect young fish from the Icelandic longline fishery. Sarah GiltzI am a doctoral candidate in Ecology and Evolutionary Biology at Tulane University. My research focuses on the larval dispersal and development of the blue crab in the Gulf of Mexico. When not concerning […]

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 […]

These Volatile Pollutants Can’t Fly, but Can They Hop?

Volatile methyl siloxanes can be easily found in personal care products (e.g. shampoo, lotion and cream) . Recently, scientists detected these compounds in soils, vegetation, phytoplankton, and krill samples from the Antarctic Peninsula region. This finding brings into question the belief that these compounds are not able to reach remote terrestrial and marine surfaces. Caoxin […]

Rise Up! Overestimated sea-level rise during the 20th century.

Calculating a global average change in sea-level over the twentieth-century is no walk in the park. This study uses a new technique to critically look at previous estimates of sea-level rise. The findings suggest that previous estimates may have been too high, but what does this mean for future sea-level rise projections? Brian CaccioppoliI am […]

Highlights from the National Shellfisheries Meeting

Ever wanted to know what it’s like to go to a scientific conference? Here’s a summary of what conferences are all about, plus the four most interesting talks I saw at this year’s National Shellfisheries Association meeting. Erin McLeanHi and welcome to oceanbites! I recently finished my master’s degree at URI, focusing on lobsters and […]
