Put your cilia in the air and wave ‘em like you just don’t care

A new study out of Woods Hole sheds some light on how marine phytoplankton enhance their ability to take up nutrients. Using fancy cameras and powerful models, the researchers suggest that short, rapid swimming bursts allow organisms to escape to greener pastures. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His […]

Benthic biology on a thermally boring deep-sea ridge

The deep ocean is vast and full of neat ocean dwellers, many of which scientists know little about. One way to investigate them is from images and videos captured during deep-sea exploration efforts using submersibles. A group of scientists did just that to quantify the benthic assemblages at different depths and a variety of substate […]

Best of both worlds: stromatolites of the intertidal zone

Did you know that the earliest form of life on Earth can still be found today? Read more to find out how researchers studied ancient formations called stromatolites growing within the intertidal zone of Cape Elizabeth, South Africa, and how salinity and nutrients influence these rare structures. Katherine BarrettKate is a 4th year PhD candidate […]

Suffocating crabs and a one-way street for carbon

Seafloor life is in danger of running out of oxygen as the ocean warms, but this may actually help to mitigate climate change. 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 […]

What lies beneath: A Gargantuan Volcanic Crater in the Arctic Ocean

Deep underneath the Arctic Ocean, researchers are studying properties of its sea floor, and colossal sized terrain features are slowly coming to the fore. Learn about one such discovery, the Gakkel caldera! Prabarna GangulyI’m a fourth year PhD candidate in the Department of Psychology at Northeastern University. My research focuses on the impact of early […]

Sharks and other ocean top predators: unlikely allies in combatting climate change?

Sharks offer more to humans than just pretty toothy grins…check out this article to learn how sharks and other top predators may act to regulate carbon production in marine food webs, which may have implications for climate change dynamics. Anna RobuckI am a third year PhD student at the University of Rhode Island Graduate School […]

A New Tool for Understanding Where Carbon Dioxide Goes

We know that CO2 is being absorbed from the air by the ocean, but how can we measure how much of the carbon in the ocean comes from human activity? By examining carbon data in the Pacific Ocean, scientists show that the ratio of heavy to light carbon atoms in the water can help answer […]

Sea lampreys: grow faster = grow male

A new study suggests that growth rate may determine if lampreys, an invasive fish in the Great Lakes becomes male or female. Read to find out more! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently working at the Smithsonian Institution’s National Museum […]

A long history of tool use in marine mammals? You otter believe it!

The use of tools by animals has been documented in a wide range of species, from birds to invertebrates, encompassing land animals and marine animals. Animals use tools to help shelter themselves as well as find their next meal. By investigating animals on a genetic level it’s possible to determine whether tool use is specific […]

Brains only for you

Brain size might dictate the laws of attraction in guppies. Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.

La Prevención de Tiburones: ¿Qué funciona y qué no?

Translated by Sandra Schleier, Original Post by Karla Haiat La percepción estereotípica pública de los ataques de tiburón puede ser resumida con una película, Jaws y sus innumerables secuelas. Películas de esta índole demuestran a los tiburones como criaturas peligrosas y malignas sin ninguna motivación que solo comerse todo lo que ven. Los medios de comunicación […]

How just 3% saves 50%: Small expansions of protected areas in “shark hot spots” could save HALF of currently endangered Sharks, Skates, and Rays

The old adage of, “work smarter, not harder” even applies to shark conservation…read on to learn how targeted expansion of marine protected areas could better protect more than 50% of imperiled shark species around the globe. Amanda IngramAmanda Ingram is a Masters of Marine Affairs Graduate Student at the University of Rhode Island. She earned […]

Pollutants produced by poriferans: using genetics to fill in blanks about sponge chemical production

Although its easy to mistake a sponge for a furry looking rock, these invertebrates and the microbes that inhabit them have some surprising chemical abilities. Anna RobuckI am a third year PhD student at the University of Rhode Island Graduate School of Oceanography in the Lohmann Lab. My current research interests include environmental chemistry, water […]

Time to update the history books: the future of radionuclides in the ocean

Scientists measured three radionuclides (137-cesium, tritium, and radiocarbon) to understand how Fukushima derived radionuclides are distributed in the North Pacific Ocean. Victoria TreadawayI am a PhD candidate at the Graduate School of Oceanography at the University of Rhode Island. I am an atmospheric chemist studying organic acids in the troposphere to better understand their role […]

Public Perceptions of Aquaculture Show Lack of Ocean Literacy

Article: Froehlich HE, Gentry RR, Rust MB, Grimm D, Halpern BS (2017) Public Perceptions of Aquaculture: Evaluating Spatiotemporal Patterns of Sentiment around the World. PLoS ONE 12(1): e0169281. doi:10.1371/journal.pone.0169281 Aquaculture is one of the fastest growing industries in the world. A 2014 report by the UN-FAO estimated global freshwater and marine farming to constitute 44% of all […]

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 […]

Marine Protected Areas need more than just a name

It is no secret that the Earth’s oceans are in trouble. Every day there is a new article on rising temperatures, ocean acidification, coral bleaching, and species extinction, to name just a few. Luckily, governments are taking notice and policies are being enacted to curb the loss of this delicate, and essential ecosystem. However, deciding […]

Atlantic confirmed as accomplice in Arctic sea ice loss

A team of scientist gathered new evidence from the Arctic Ocean, revealing a new suspect responsible for rapidly melting Arctic sea ice. 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 role in climate. For my research I sometimes […]

Shark attack prevention: what works, what doesn’t?

We aren’t going to need a bigger boat to prevent shark attacks…read this review article to get an idea what shark attack prevention strategies are best for both humans and sharks! Karla HaiatI’m an Undergraduate student at University of Rhode Island majoring in Ocean Engineering and Marine Biology. I’m interested in the intersection between technology, […]
