Lights out: How the aquatic food web is responding to coastal darkening in the North Sea

Have you ever been on a plane, flying over the coast, and noticed a stream of brown-colored water draining from land into the blue-green coastal waters? Scientists have been studying this phenomenon for years and came up with the term coastal darkening, which may have serious implications for the aquatic food web. Cindy LebrasseBorn and […]

Blue is the New Green: How Melting Sea Ice Might Save Us Billions

As Arctic sea ice melts, the ocean absorbs more carbon. Could this actually be a good thing? Researchers in Norway answer just that, quantifying the economic value of this increased Arctic carbon storage and how long it will last. Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri […]

Fishing or Farming: Can Fisheries and Offshore Wind Farms Coexist?

Last month, President Biden announced that the US will be turning to offshore wind farms (OWFs) to meet the growing need for clean energy. While this is an exciting step forward for clean energy, some are concerned about how OWFs might affect and restrict fishing activities in certain areas. A new study carried out in […]

Bearing teeth: How polar bear dental health can illustrate climate change

It is no secret that climate change is damaging Arctic ecosystems. Because of melting sea ice, Arctic species have had to change their behaviors in order to survive. Polar bears in particular have been spotted eating new and strange diets. But what do these diets consist of, and are they causing harm to this species? […]

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?

A sediment record from a lake in northern Canada is being used to reconstruct Atlantic Ocean temperatures at a resolution never achieved before. 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 […]
