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 […]

Predicting the future of coral reefs is complicated by human impacts

Coral reefs are often referred to as the “rainforests of the sea” for hosting a great diversity of life, but this incredibly productive ecosystem is seriously threatened by human activities. To better evaluate changes happening in the reef communities and develop strategies to mitigate damages done to coral reefs, understanding how human activities affect our […]

Two by two includes corals too? Researchers call for a coral “Noah’s Ark”

In the Bible, the story of Noah’s Ark describes a storm so intense and so long that the earth is covered in water, killing all except those protected in a massive boat. Today, coral scientists are proposing their own “Noah’s Ark,” but this time the relentless storm is climate change. Kristin HuizengaI am a PhD […]

The Bellagio of the natural world: glacial fountains

Glaciers are sentinels of global change, yet there is still much to be learned about how glaciers melt, and in turn, how melting glaciers interact with the surrounding water. Read on to find out how scientists are working to understand how glacial meltwater forms fountains that change the surrounding water. Katherine BarrettKate is a 4th […]

A shell of a ride: Pteropod survival through past mass extinction events and insights into present climate change

By looking at DNA and fossils of pelagic sea snails, Dr. Peijnenburg and colleagues are beginning to understand how this group has withstood past climate change, and how they may survive current ocean acidification. Gabrielle StedmanI am currently a 3rd year PhD student in Biological Oceanography at the University of Hawai‘i at Manoa. I use […]

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 […]

Artificial Upwelling Saves Corals from Bleaching

Coral reefs are under threat due to a warming climate. Learn about a technologically-savvy new way to counteract the effects of these warmer temperatures: Artificial Upwelling systems. Amanda SemlerI’m a PhD candidate in Earth System Science at Stanford University, and I study how microbes in deep ocean sediments produce and consume greenhouse gases. I’m a […]

SURFO Special: Summer Research or Summer DIY Project

Andria Miller is a rising senior at Jackson State University, majoring in Biology and minoring in Chemistry. This summer she worked remotely with Susanne Menden-Due and Pierre Marrec through the URI GSO Summer Undergraduate Research program. Plankton are a community of organisms that provide basic fuel for marine and freshwater ecosystems. Freshwater ecosystems, such as […]

Bowhead Whales Threatened by a ‘Killer’

The Arctic is experiencing dramatic changes in sea ice. How will this warming affect the marine life? Scientists find there may be an increasing threat to the already endangered bowhead whale. What it is may surprise you. Elena GadoutsisI’m not the typical marine biologist – I started my career as a nurse working in intensive […]

How cold did the ice age really get?

Scientists revisit the question of global temperatures during the last ice age. They tackle this with state of the art climate models and geochemistry to give a picture that’s more accurate than ever before. Shawn WangI am a PhD student studying climate physics and marine geology at MIT and Woods Hole Oceanographic Institution. I am […]

If you can’t stand the heat, get out of the kitchen: An analysis of phytoplankton with changing ocean temperature

If you went to the beach and the water is cold, would you jump in? The same questions pertain to very small creatures called phytoplankton off the coast of Mexico. A group of scientists recently studied the behavior of phytoplankton as the ocean’s temperature due to large weather events like El Niño and found some […]

How will climate change affect the Southern Ocean ecosystems?

Changes in the Southern Ocean can affect global climate, and understanding the Southern Ocean’s response to climate change helps us better predict future climate. A team of researchers have looked into this question to predict how human impact on Earth’s climate will affect the Southern Ocean and its ecosystem in the near future. Jiwoon ParkI […]

How corals thrive in deep ocean waters

Ever wonder how corals live in the cold, dark depths of the ocean? How could climate change impact these organisms? Read on to find out more. Samantha SettaI’m a PhD student in the Rynearson Lab at the University of Rhode Island (URI) Graduate School of Oceanography (GSO). My research interests are focused on human impacts […]

Consider the marsh crab: Climate change shifts which species are key

Munching, nibbling and burrowing their way through life, the humble marsh crab can now add “keystone species” to its ecological resume. As sea level rise has inundated shorelines on the East Coast of the United States, marsh crabs have emerged as important players in shaping how marshes respond to climate change. Kristin HuizengaI am a […]

A Fishy Ally to Help Coral Reefs

What if we had something on the inside to help us fight climate change’s impacts on coral reefs? A helpful ally which could increase coral bleaching tolerance and boost post-bleaching recovery in the field and in real time? As it turns out, we do: damselfish. Rishya NarayananRishya is a multimedia science communicator with an MS […]

Stop Clowning Around: Cyanide Fishing in the Indo-Pacific

What does cyanide have to do with the tropical reef fish sold as pets and showcased in aquariums? A recent paper by Madeira et al. explore how illegal cyanide fishing is devastating Indo-Pacific reef ecosystems. Ashley MickensI recently graduated with a degree in Environmental Earth Science and Sustainability from Miami University of Ohio, and I’m […]

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 […]
