How do greenhouse gases move?: An updated study on nitrous oxide exchange from the ocean to the atmosphere

Our atmosphere is composed of different gases like oxygen, nitrogen, and carbon dioxide. These gases can absorb energy, sent from the sun, reflecting off of the Earth’s surface. While scientists can measure and estimate their amounts in the air, gases have the ability to move between the ocean and the atmosphere. This behavior, while interesting, […]

Renewed hope for reef-building corals to combat climate change.

If you have ever had a chance to snorkel in a reef, you would agree that it is an unforgettable experience. Its special mainly because of the colorful corals and the diverse life forms they support. But corals around the world are being hit hard from effects of warming ocean temperatures and ocean acidification. Corals […]

Map with shipping corridors

How do we navigate a climate-changed sea? By getting Inuit perspectives on the map.

Climate change is impacting the waters of Arctic Canada. As ice cover declines, interest in using these routes for international trade and shipping is increasing. However, increasing ship traffic has real implications for the health of the people and wildlife of this area. Inuit communities took part in the Canadian government’s planning process to ensure […]

How much heat is stored in the oceans: Insights from ice cores

Reviewing: Shackleton, S., et al. “Global ocean heat content in the Last Interglacial.” Nature geoscience 13.1 (2020): 77-81. DOI: https://doi.org/10.1038/s41561-019-0498-0 Water is a super-sponge of heat On hot summer days, we often run to the beach or swimming pool to cool off and relax, but did you know that our planet also stays cool thanks to […]

Is our plastic dependence accelerating climate change?

  Reference: Royer, Sarah-Jeanne, Sara Ferrón, Samuel T. Wilson, David M. Karl. “Production of methane and ethylene from plastic in the environment.” PloS One 13, e0200574 (2018). Doi: https://doi.org/10.1371/journal.pone.0200574 Plastic? What’s the big deal? Since the 1950’s, over 6 billion tons of plastic have been produced globally. Less than 10% of plastic is recycled, and […]

Let Marine Microbes Be Thy Medicine

The deep sea is a treasure trove of disease-fighting compounds–and is even helping us in the fight against the novel coronavirus. 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), and […]

Size Matters in Kelp Forests – Big, Dense Populations Are Better Equipped to Recover from Disturbance

Kelp are habitat-forming species, the “ecosystem engineers” of our coasts. Standing metres tall and sheltering coastal habitats from the full force of the ocean’s waves, kelp provide a refuge for a variety of marine animals and create a forest ecosystem similar to what you might find in the temperate latitudes on land. They are nursery […]

Arctic Unicorns: Understanding the past, present, and future of narwhals and their mysterious tusks

Why do narwhals have tusks that make them look like unicorns? As climate change continues, what is the fate of narwhals and their enigmatic tusks? Two recent studies of these unicorns of the sea start to answer questions about their past, present, and future. Julia ZehI am a second-year PhD student at Syracuse University studying […]

Climate-driven events leave an imprint on corals in the Great Barrier Reef

In this re-post, we discuss the ecological memory of corals from bleaching events that occurred back-to-back in 2016 and 2017. With this pattern repeating itself in 2020, has mass bleaching become a near-annual event? Nyla HusainI’m a PhD student at the University of Rhode Island Graduate School of Oceanography. I use models to study how […]

Envisioning a better world with climate impact modeling

After October 2018, the global perspective on climate change started to shift. We dive into climate impact models, and how they could help us plan for a future in which climate change impacts every aspect of our lives. Nyla HusainI’m a PhD student at the University of Rhode Island Graduate School of Oceanography. I use […]

Catch prey while the sun shines – Herring grow bigger when they can see their food

It is a truth universally acknowledged, that a sea creature in possession of a home in higher latitudes (further from the equator), must (on average) possess more size than its mid latitude neighbors. But why should high latitude fish be in possession of such a good fortune? Kristin HuizengaI am a PhD student studying Biological […]

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 […]

One thousand ways to experience climate loss

What exactly are we at risk of losing as the planet warms? One recent study aims to track climate-driven loss that is hard to define. 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 […]

Ocean Acidification is no Small Matter to Two-Toned Pygmy Squid Reproduction

Nestled in seagrass and darting through Indo-Pacific, nearshore waters, two-toned pygmy squids are miniscule cephalopods that represent a much larger problem afflicting our ocean: ocean acidification’s impact on productivity. 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 […]

Of Wildfires and Oceans

Wildfires are all over the news, from California to Australia, but do these terrestrial events have any impact on ocean ecosystems? Is it possible that wildfires can cause massive coral die-off across reefs? A research paper from 2003 provides some insight into these questions, and points to a need for more studies on the links […]

Protecting marine ecosystems by tracking top predators

What do canaries have in common with polar bears, sea turtles, and sea birds? Read on to find out how these marine animals we love and want to protect are receiving attention for their potential to protect marine ecosystems. Katherine BarrettKate is a 4th year PhD candidate in the Biological Sciences Department at the University […]

Turning Knowledge into Action: How the Town of Truro Adapted to Increasing Flood Risk Under Climate Change

Global sea level is projected to rise at a rate of 3.7mm/year throughout the first half of the next century, according to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPPC). As coastal communities around the world brace to meet this worrying projection, it’s become clear that many simply have no options […]

Sea-sick – Examining ocean diseases through literature

From coral bleaching to sea star wasting disease, stories of an unhealthy ocean have been all over the news. But are the animals in the sea actually sicker than before? Without long-running data sets tracking disease over time, it can be hard to see if diseases are growing more prevalent. In spite of this, Dr. […]

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 […]

Sea-Level rise may be higher than previously estimated

Kulp, S.A., Strauss, B.H. New elevation data triple estimates of global vulnerability to sea-level rise and coastal flooding. Nat Commun 10, 4844 (2019) https://www.nature.com/articles/s41467-019-12808-z As a part of the natural cycle, sea-levels have increased or decreased throughout our planet’s history. Water frozen in ice caps would melt during the hotter periods, contributing to the sea level […]
