Open ocean polynyas: How these holes in the ice mysteriously appear

For decades now scientists have been fascinated by polynyas, holes that appear in the polar sea ice whose causes are still unclear. Recent data from robots that recorded two of these cavities opening sheds light into how they are formed. Shawn WangI am a PhD student studying climate physics and marine geology at MIT and […]

It’s a cold, cold winter for Arctic phytoplankton

Ever wonder what winter is like for marine organisms? What about those that rely on light for growth? In a recent study of microscopic photosynthesizers in some of the most extreme winter conditions in the Arctic, a group of scientists set out to investigate. Samantha SettaI’m a PhD student in the Rynearson Lab at the […]

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 have always been happiest in nature – exploring forests, traveling to the ocean, or working with […]

Skating on Thin Ice

Newly developed global climate models show us that Arctic Sea ice may be more unstable than we previously thought. The first ice-free summer in the Arctic may be just around the corner. Shawn WangI am a PhD student studying climate physics and marine geology at MIT and Woods Hole Oceanographic Institution. I am interested in […]

Antarctic Sea Ice – What do Adélie Penguins have to do with it?

In light of global climate change and warming ocean waters, is there any good news? Turns out some Antarctic penguins will benefit in the short term with less sea-ice cover. 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 […]

Arctic Viruses Infecting sub-Arctic Seals: How Climate Change is Creating Marine Epidemics

With all the preparations being made to help human populations get through Covid-19, many are wondering about the effect the coronavirus or similar viruses may have on our animal counterparts. Some panicky pet owners are even rushing to get their dogs special Covid masks. While it’s highly unlikely your dog will catch Covid-19, SARS-type viruses […]

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 PhD candidate at Syracuse University studying marine […]

Key Role of Sea Ice in Glacial Cycles

A recent study using an idealized model finds that changes in Antarctic sea ice and circulation, triggered by atmospheric cooling, stimulate carbon drawdown and thus play a large role in glacial-interglacial transitions. Channing PrendI’m a physical oceanography PhD student at Scripps Institution of Oceanography in La Jolla, California. I use a combination of numerical models, […]

What caused a massive hole in Antarctic sea ice?

In 2016 and 2017, a massive hole developed in the Antarctic sea ice. Scientists investigated the processes that led to this formation and found that it was related to anomalous saltiness and storm activity in the region. Channing PrendI’m a physical oceanography PhD student at Scripps Institution of Oceanography in La Jolla, California. I use […]

Phytoplankton Expanding Northward as Arctic Sea Ice Retreats

A recent study uses satellite data to show that Arctic sea ice retreat is causing changes in the timing and location of spring phytoplankton blooms, which play a large role in the regional ecosystem and carbon cycle. Channing PrendI’m a physical oceanography PhD student at Scripps Institution of Oceanography in La Jolla, California. I use […]

Millennial algae are not as productive: lazy, or less sea ice opportunities?

Why aren’t Arctic phytoplankton as productive as they used to be? Is it a lazy millennial thing, or something more complex and systematic? Researchers use observations to learn more about this generation of phytoplankton, and what it could mean for Gen Z and beyond… Nyla HusainI’m a PhD student at the University of Rhode Island’s […]

Sea Ice Modifies Biological Processes

A recent study investigates the relationship between sea ice variability and phytoplankton growth in climate models. Phytoplankton are responsible for most of the transfer of carbon dioxide from the atmosphere to the ocean, therefore this work can help us understand and predict how the ocean’s ability to regulate climate might change in the future.     Channing […]

When life gives you global warming, make pancake ice in ocean wave models

Sea ice is retreating, the Arctic is opening up, and wave activity is increasing. What does this mean for the ocean and atmosphere? The refreezing season of autumn may have some answers. Nyla HusainI’m a PhD student at the University of Rhode Island’s Graduate School of Oceanography. I use a small-scale computer model to study […]

Sea Ice Drives Global Circulation

A recent study uses observational data from the Antarctic to show that sea ice processes help drive the global current system called the overturning circulation. This result suggests that changes to sea ice extent in the Antarctic could impact large-scale circulation as well as the ocean’s uptake of heat and carbon dioxide. Channing PrendI’m a […]

The Polar Vortex, Bomb Cyclones, and Climate

Bomb cyclones, the polar vortex, and climate – they’ve all been in the news in recent years, but how do they intersect? A new study finds a link between mid-latitude cyclones and enhanced sea ice melt in the Arctic. Nyla HusainI’m a PhD student at the University of Rhode Island’s Graduate School of Oceanography. I […]

Why is Antarctic Sea Ice Growing?

Despite increases in global ocean temperatures, long-term trends actually show an increase in Antarctic sea ice extent. There are a number of reasons for this apparent paradox: geography, ocean properties, and atmospheric circulation to name a few. This paper examines the role of atmospheric variability in driving Southern Hemisphere sea ice trends. Channing PrendI’m a […]

Sea Ice Mixes it Up

Sea ice extent and concentration is driven by a complex combination of circulation and mixing, as well as interaction with the atmosphere. Understanding these processes is critical to improving climate models. This study uses models to examine the dynamics in marginal ice zones, which is becoming increasingly important for future climate predictions. Channing PrendI’m a […]

It’s getting cold in here!

As we here into winter, we notice changes taking place in nature all around us. But what do microbes in the ocean do when it gets cold??? Laura ZinkeI am a PhD student studying sediment geomicrobiology at the University of Southern California. My primary research interests lie deep under the sea studying how microorganisms survive […]

Melting ice, shifting microbes

Polar bears have been the poster child for sea ice melting in the Arctic. But what does sea ice loss melt mean for the Arctic’s most numerous members – its microbes? Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes […]

Antarctic krill retreat to icy terrace homes for the winter

An international research time dives beneath the ice in Antarctica’s remote oceans to understand how krill larvae make use of sea ice to survive the winter and make it to adulthood. 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 […]
