Biological oceanography
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 4th year PhD student at the University of […]

Not So Organic Marine Snow
What happens when plastic pollution mixes into the ocean carbon cycle? Read to find out more about how plastic from the surface ocean might reach mussels living at the bottom of the sea! Melanie FeenI am a first year graduate student at the Graduate School of Oceanography at University of Rhode Island. I use robots […]
Octopus Mama Drama: Research Expedition Bonus Science
Dorado Outcrop is a small underwater mountain that first received attention from a few scientists because the seafloor that it sits upon is colder than what is expected. It ended up in the media spot-light because of the hundreds of octopuses that call it home. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, […]
Fixin’ to lose: Trichodesmium reacts to climate change
Nitrogen is vital for all life on the planet. One of the main global sources for nitrogen, the bacteria Trichodesmium, may stop providing nitrogen to the global cycle in an ocean affected by climate change. LeAundra JeffsI am a Master’s Candidate at University of Delaware where I study the evolution of microbes in the sediments […]
Turn Up The Heat, Turn Down the Productivity
What happens if we do not curb carbon emissions? In a recent study, Moore and co-authors (2018) predict the implications of sustained carbon emissions. Ocean nutrients may be redistributed leaving much of the global ocean in a state of declining biological production! Check out this article to learn more! Melanie FeenI am a first year graduate […]
Cyanobacteria invasions… from space?
They may not come from space, but they can be seen from up there! Learn how microscopic plants called cyanobacteria accumulate in the Baltic Sea, how they’re measured with satellites, and what it all means. Nyla HusainI’m a 4th year PhD student at the University of Rhode Island Graduate School of Oceanography. I use models to […]
Arctic Lights
We often think of the Arctic as a cold, dark place. But as sea ice continues to recede in the far north, the Arctic ocean might get quite a bit lighter. A new study out of Norway suggests these changes could alter the behavior of a particularly important type of plankton. Eric OrensteinEric is a […]
Biofilms are a prominent first step in the colonization of wood-falls
A profound yet never-before-appreciated first step in the colonization of sulfur oxidizing bacteria on the surface of wood-debris in the deep-sea is attributed to sugars and other labile components of wood. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who has been lucky to have had many roles […]
The Declining Japanese Eel Population: Is Ocean Circulation to Blame?
Recent declines in Japanese eel populations have been attributed to overfishing, but that may not be the only factor at play. Chang et al. investigate whether recent changes in ocean circulation might help explain this alarming trend. Julia DohnerJulia is a PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus is […]
Pteropods are Ptough: How one of the ocean’s most fragile creatures may cope with climate change
Climate change, due to the increase in atmospheric carbon dioxide from fossil fuel burning, is arguably the most important issue facing our planet. One of the most detrimental changes already in progress is the shifting pH of the world’s oceans, known as ocean acidification. Although the speed with which the planet is changing does not […]
Snowmageddon: A lighthearted start to Marine Snow theme week
While the term “marine snow” may conjure images of an aquatic winter wonderland, some aspects of this phenomenon may not inspire a Bing Crosby song. Marine snow is responsible for transporting many of the nutrients found in the surface, sunlit waters of the ocean to depths where it becomes a significant food and nutrient source […]
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 […]
Growing a Scientist: Undergraduate Research 2017
Each summer, the University of Rhode Island Graduate School of Oceanography (GSO) hosts undergraduate students from all over the country to participate in oceanographic research. These Summer Undergraduate Research Fellows (SURFOs) have not only been working with GSO scientists, but they have spent part of their time learning how to communicate this science to the […]
2+ Ocean Exploration Expeditions to Join This Year
Ninety-five percent of the ocean is unexplored, but there a few ocean expeditions happening this year that you can join! How? You can explore alongside scientists in real time. Read more to find out! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently […]
Harmful Algal Blooms Find Homes Further North as Waters Warm
Before the late 20th century, reports of illness from toxin-producing algae had been absent from most northern coastlines. But in the past 30 years, the incidence of algae-related poisonings in humans have been increasing in areas such as the U.S. Pacific Northwest and the United Kingdom. By modeling harmful algae growth in the North Atlantic […]
The Missing Mechanism: How Ocean Fronts Impact Sinking Organic Matter
Phytoplankton are central to the ocean’s carbon cycle, converting carbon dioxide into organic molecules that sink into the sea’s interior. But the ocean is moving and variable. As a result, we don’t have good estimates of how many of these phytoplankton-made molecules exit the upper ocean where phytoplankton reside. Find out how Stukel et al. […]
The Entire Ocean in a Drop
Article: Stoeckle MY, Soboleva L, Charlop- Powers Z (2017) Aquatic environmental DNA detects seasonal fish abundance and habitat preference in an urban estuary. PLoS ONE 12(4): e0175186 Effectively managing fish populations requires accurate and timely monitoring data. Scientists and environmental managers need to know when (presence/absence data), where (location data), and how many fish (abundance […]
The Molecular Industrial Complex: What shrimp exoskeleton formation can tell us about life’s building strategy
Have you ever wondered just how our bodies know to repair damaged skin or build muscle after an intense workout? Without even thinking about it, these processes are carried out behind the scenes while we go about our lives. Read further to see how a team of scientists have used the lifecycle of the mighty […]
Put your cilia in the air and wave ‘em like you just don’t care
A new study out of Woods Hole sheds some light on how marine phytoplankton enhance their ability to take up nutrients. Using fancy cameras and powerful models, the researchers suggest that short, rapid swimming bursts allow organisms to escape to greener pastures. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His […]
