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 second-year PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus […]
The Many Modes of Antarctic Ice Loss
The Western Antarctic Ice Shelf has been melting rapidly in recent decades, largely due to upwelling of deep ocean water that has been gradually warming. Atmospheric systems can influence the ice-sheet height anomalies on interannual time scales. Paolo and other researchers used satellite altimetry to study which processes have the greatest effect in one region […]
More Intense Summer to Winter Swings in Oceanic Dissolved CO2
Ocean CO2 levels vary depending on the time of year. Landschützer and his colleagues are the first to show that human-emitted CO2 is making these seasonal swings more severe, potentially to the detriment of many marine organisms. Julia DohnerJulia is a second-year PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus […]
Agricultural Stewardship Could Prevent Invasive Species Takeover Downstream
Phragmites australis, or Common Reed, is a marine grass likely introduced to North America from Eurasia in the late 1800s through the garden trade. It has since become one of the most aggressive invaders in history, replacing native grasses in wetlands and disrupting native ecosystem function. Wetlands are interesting study systems for invasive plants. […]
Marine Snow & Muddy Megacoring on the Southern Ocean
Check out this guest post by Marlo Garnsworthy to read about an exciting voyage to the Southern Ocean…Marlo took part in a several week research cruise to learn about climate change using sediment samples from the region…read on to learn about the experience and see Marlo’s great pictures! Anna RobuckI am a third year PhD […]
Going viral: relationships between coral reef health and viruses
What organisms live in coral reefs? Corals (obviously), fish, snorkeling tourists…but some of the most important members we can’t even see with the naked eye, and some argue aren’t even alive! In this post we explore the role of viruses in coral reefs, and what we do – and don’t – know about coral-virus interactions. […]
Appreciate seafood? Climate change isn’t your friend.
Seafood depends on healthy food webs that support fish populations…but food webs depend on environmental conditions! Read on to learn how changing environmental conditions due to climate change stand to change the base of the food web, with far-reaching consequences. Anna RobuckI am a third year PhD student at the University of Rhode Island Graduate […]
Which Paris Agreement Countries Mention the Ocean, and Why?
Do nations mention the impact of climate change on the ocean in their Paris Agreement pledges? And why do some countries include more about the ocean than others? To find out, Gallo et. al pick apart each country’s National Determined Contribution plan. The results are not quite what you’d expect. Julia DohnerJulia is a second-year […]
Ocean Acidification: No Longer Confined to the Sea Surface
Acidification, one of the highest-visibility impacts of human activity on the ocean, was thought to be confined to its upper layers. Chen and his colleagues show that’s no longer the case. Julia DohnerJulia is a second-year PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus is on chemical oceanography, which often […]
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 […]
Oceanic Outlook in the New Government Climate Report
Ocean warming, acidification, sea-level-rise, and increased coastal storm intensities are just some of the stark projections highlighted in a recently-released U.S. Government climate report. Zoe GentesZoe has an M.S. in Oceanography and a B.S. in Geologic Oceanography from URI, with a minor in Writing and Rhetoric. She was recently a Knauss Marine Policy Fellow in […]
How to model climate change in an Arctic food web
The climate is changing, and so are Arctic food webs. But our knowledge of how food webs respond to warmer Arctic water temperatures is incomplete, so scientists use models to help further understanding of future food web scenarios. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at the University of […]
The Subtle Response of Plants to Rising CO2 Levels
Plants need carbon dioxide. What do they do when there’s more and more of it in the atmosphere? Julia DohnerJulia is a second-year PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus is on chemical oceanography, which often manifests as the intersection of the biology, chemistry, and physics of the ocean. […]
Local disturbance and global warming unite to make seagrasses taste better to predators
Seagrasses form some of the most important habitats in the marine world. Under threat from global climate change as well as local disturbances, they’re also the subject of wide-spread investigation. Field and laboratory studies have shown that nutrient pollution, temperature changes, acidification, and other disturbances will negatively affect seagrass health, at the individual and community […]
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 […]
Fireproofing the Arctic
Chemicals that are stable enough for our everyday use are often remarkably stable in the natural environment as well. This poses a problem because these chemicals can travel far from sources and end up in pristine environments like the Arctic. In the study described here, researchers from Germany and China joined forces to measure one […]
Small but perhaps not so mighty: The second edition of the epaulette shark saga
A sneak peak of more awesome epaulette shark research currently being conducted at the New England Aquarium. We know how these sharks fair with ocean acidification, but what about ocean warming? Carolyn WheelerI am currently a PhD student studying marine science at the University of Massachusetts Boston, with my research based at the New England […]
Orca vs Narwhal
Orcas are natural predators of narwhals, but they are seasonally kept at bay by Arctic sea ice. As the Arctic becomes increasingly ice-free, killer whales are arriving earlier and hanging out longer in narwhal habitat. How do narwhals fare? Read more to find out! Megan ChenI graduated with a Masters of Coastal & Marine Management […]
Spotlight on Constructed Wetlands
Wetlands are one of the world’s powerhouses for ecosystem services, filtering our water, controlling coastal erosion, and providing feeding and nursery habitat for a huge variety of wildlife. They are super productive, containing plant species that grow fast and therefore contribute a huge influx of organic material to the system when they die and start […]
It’s Getting Hot In Here: How Ocean Acidification and Warming Affect Shark Hunting and Behavior
Elasmobranchs such as sharks and rays face physiological and behavioral changes due to ocean acidification and rising ocean temperatures. Read about how these changes influence how sharks hunt and their role in the marine ecosystem. Aditi TripathyHello! I am an undergraduate student majoring in Marine Biology and with a minor in Acoustics at the University […]
