The Circle of Life: Understanding Lionfish Life Cycles

We know who’s the king of the jungle, but who’s the king of the reef? Lionfish may look cool, but they are actually invasive in the Atlantic and the adults have no natural predators. This new paper explains how understanding the early life stages of lionfish may help control their population in the Western Atlantic […]

Microbes pull nitrogen out of air to feed the warming oceans

Some ocean microbes can take nitrogen gas from the air and convert it to different forms that can be used by other organisms. Read on to learn about how this important process is going to be affected by ocean warming in the future. Jiwoon ParkI am a PhD student in chemical oceanography at University of […]

Does coral size matter?

Nina Bean is a 2nd year master’s student at the California State University, Northridge in Dr. Peter Edmunds’ Polyp Lab. She is studying how coral traits and competitive outcomes scale with coral size at various life stages. When she is not doing research, she enjoys rock climbing, running, and underwater photography. Read her guest post […]

The New Mollusk on the Block

Have you ever wondered about how marine animals travel to a new place, you know, when they can’t swim there? Phorcus sauciatus, a marine top snail, doesn’t swim around like a fish. As an adult, this snail’s only method of movement is by crawling around on a surface with its foot. So how does this […]

Warming up to the neighborhood: a gentoo penguin’s new digs

With warming temperatures, scientists expect to see species popping up in environments where they’ve previously been absent. Climate change virtually guarantees animals will move into new regions, either following prey or searching for more familiar temperatures. In the case of the gentoo penguin, it means a new frontier as colonies push to the edges of […]

The Ocean Robot Revolution

This year marks the start of the United Nations Decade of Ocean Science. To reach its ambitious targets, we require new platforms to observe the ocean—such as armies of ocean robots. 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 […]

Oxygen Minimum Zones: Should we be worried?

Reviews and syntheses: Present, past, and future of the oxygen minimum zone in the northern Indian Ocean It is no secret that oxygen is essential for most life forms, but there are certain areas in the oceans where there is little oxygen. In their recent research, Dr. Rixen from the Leibniz Centre for Tropical Marine […]

Understanding the Demise and Recovery of Coral Reefs

In the last couple of decades we’ve learned a lot about the decline of coral reefs around the world. But there are still many unknowns. Scientists just discovered one of the constraints that prevent coral recovery after a bleaching event. Pablo Brenes CotoHello! I am a science communicator who loves sharing stories about the ocean. […]

Missing the (Kelp) Forest for the Trees: An Overlooked Factor in Blue Carbon Storage

A recent study exposes an overlooked carbon sink in the form of kelp forests. According to scientists’ estimates, a kelp forest in Australia sequesters 3% of global carbon per year, and this has important implications for the rest of the global carbon budget. Ashley MickensI recently graduated with a degree in Environmental Earth Science and […]

Catching a ride on plastic: how dangerous bacteria might travel across oceans

Plastic is abundant in the ocean ecosystem. Not only is it harmful to marine animals, but as scientists discovered, it also transports disease-causing bacteria around the ocean. How can the plastic debris in the ocean spread sickness? Diana FontaineI am a PhD student in the Rynearson Lab studying Biological Oceanography at the Graduate School of […]

Marine heat waves leave seabeds ice cold

Marine heat waves are becoming more frequent and intense due to climate change, and can have negative effects on invertebrate spawning success. Hannah CollinsI’m a second year Masters student in Oceanography at the University of Connecticut, Avery Point. My current research interests involve microplastics and their effects on marine suspension feeding bivalves, and biological solutions […]

One Fish, Two Fish, Climate Change, Who Lives?

There is variation within species, and this variation can lead to some individuals surviving better in the face of environmental change. But it is difficult to predict how animals will respond to an environment that is changing faster than they can evolve. Luckily, some scientists found a clever way to study how individuals might respond […]

A Small Pool Makes a Big Splash

Researchers find evidence that a small region in warm waters in the western Pacific could have played a big role in the global warming trend we have been observing. Shawn WangI am a PhD student studying climate physics and marine geology at MIT and Woods Hole Oceanographic Institution. I am interested in using geochemical methods […]

Can clays from northern Canada provide a 3,000-year temperature record of the Atlantic Ocean?

Shawn WangI am a PhD student studying climate physics and marine geology at MIT and Woods Hole Oceanographic Institution. I am interested in using geochemical methods and climate models to study periods […]

Fossilized Deep-Sea Corals Reveal Ancient Ocean Circulation Patterns

An increase in atmospheric carbon dioxide concentrations helped end the last ice age. But what caused the carbon dioxide increase in the first place? A team of scientists used the fossilized skeletons of deep-sea corals to find out. Amanda SemlerI’m a PhD candidate in Earth System Science at Stanford University, and I study how microbes […]

Does history repeat itself?: Investigating the Paleocene-Eocene Thermal Maximum

Everyone knows that Earth’s climate changes. With the rapid increases in human-influenced global warming and ocean acidification, we need to be able to model and predict the future. What if we could use the past? A similar time period called the Paleocene-Eocene Thermal Maximum (PETM) exhibited similar climate changes. Scientists have investigated the PETM and […]

The Indian Ocean Dipole: How Climate Change affects South East Asia and Beyond

Extreme weather patterns in South East Asia and West Africa devastate local communities. Scientists study historical climate of the region to investigate if modern climate change is intensifying these disasters. Shawn WangI am a PhD student studying climate physics and marine geology at MIT and Woods Hole Oceanographic Institution. I am interested in using geochemical […]

Blue Mussels Face a Dual Dilemma When their Microscopic Gill Hairs Slow Down

The frequency at which tiny, hair-like structures on gills called cilia beat back and forth reveals how blue mussels respond to environmental pressures caused by climate change. Rishya NarayananRishya is a multimedia science communicator with an MS in Media Advocacy from Northeastern University, specializing in Environmental Science Communications and Policy. She spent a year in […]

Climate Change Is Causing A Stormy Future

A new study verifies a decades-old prediction that tropical cyclones are becoming more intense due to climate change, using a novel, satellite data-driven approach. 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 […]

SURFO Special: Has COVID-19 Affected Plane Emissions?

Since March, COVID-19 has had a huge impact on how we live our day-to-day lives. But how has it changed our carbon emissions? SURFO student Bella Luikart spent this summer with the Palter Lab at GSO to find out. Nyla HusainI’m a PhD student at the University of Rhode Island’s Graduate School of Oceanography. I […]
