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 4th year PhD student at the University of Rhode Island Graduate School of Oceanography. I use models to study small-scale turbulence […]
Seaweed may be a winner in a warming world
Have you ever thought about ocean critters that might benefit from climate change? Hernández et al. collected six species of seaweed to investigate who might thrive in the warmer, more acidic waters of the future. Read more to see if any seaweed species were winners! Victoria TreadawayI am a PhD candidate at the Graduate School […]
Warmer Waters Will Trap Nutrients Down Deep
Climate change is warming the ocean and altering how deep water is transported. Researchers in this study estimate that by the year 2300 these changes will have drastically altered where nutrients are available in the ocean causing up to a 15% decline in net primary production globally! Read more to see how this will happen […]
Marine diatoms eat climate change’s dust
Multiple, interacting factors from climate change make it difficult for scientists to predict how marine life will respond to climate change. Read on to find out how researchers studied the effects of dust deposition, ocean warming, and increased carbon dioxide concentrations on a common marine diatom. Katherine BarrettKate is a 3rd year PhD candidate in […]
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 PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus is on biogeochemistry, which, as the name […]
Changing winds drive more ocean heat capture
A team of scientists look to the Southern Ocean to show where and why the ocean has been storing extra heat. 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 it’s role in climate. For my research I sometimes spend […]
Coastal waves link far-off winds to melting Antarctic ice
The ocean surrounding Antarctica is warming, rapidly melting ice shelves from below. Scientists have now discovered that strong winds thousands of miles away can cause this warming with the help of large, very fast waves that propagate around Antarctica’s coast. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My […]
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 […]
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 with a minor in Acoustics at the University of […]
Suffocating crabs and a one-way street for carbon
Seafloor life is in danger of running out of oxygen as the ocean warms, but this may actually help to mitigate climate change. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, and what […]
Take my breath away: Decline in oceanic oxygen levels fifty years in the making
Most marine organisms require dissolved oxygen to sustain their survival. So what is the current status of oceanic oxygen levels? Read on to learn about the oft under appreciated resource of our planet! Prabarna GangulyI’m a fourth year PhD candidate in the Department of Psychology at Northeastern University. My research focuses on the impact of […]
Throwing Babies out with the Sea Ice: Ringed Seals Response to Ice Decline
As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I […]
Now we got bad blood: Oxygen binding is not affected by haemoglobin subtype in Atlantic cod
Why do northern and southern populations of Atlantic cod have different haemoglobin subtypes? A recent study upsets over 50 years of theory. Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and […]
Antarctica’s bottom waters freshen up
A team of researchers went back to the same part of Antarctic after a decade to see how the deep ocean had changed, and were surprised to find the deep ocean was fresher than they expected. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on […]
Hard Coral or Macroalgae? Coral Reefs May Have Another Option
Most of the time coral reef communities are discussed, it seems the focus is whether they’re dominated by hard coral or algae. It turns out there may be other possible outcomes for reefs in the future. Find out more in today’s oceanbites! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and […]
The Pacific Pacemaker: Using Models to Explain Warming Hiatus
While the Earth’s mean surface temperature is slowly increasing, there are occasional, temporary slowdowns in the overall trend. The Interdecadal Pacific Oscillation, a strong, varying climate pattern, may be held accountable for the phenomenon. Zoe GentesZoe has an M.S. in Oceanography and a B.S. in Geologic Oceanography from URI, with a minor in Writing and […]
If You Must, Adjust? Polar Bears Leaving Sea Ice in the Arctic
Everyone knows that polar bears have become the poster children for species threatened by climate change. And it’s for good reason that they are. Polar bears rely on sea ice for access to prey, finding mates, and creating dens. The persistence of the species depends on the state of sea-ice and more generally a healthy […]
Ocean circulation keeping it cool in Antarctica
A group of scientists have delved deeper to solve the puzzle of why the ocean around Antarctica has been cooling, while the rest of the ocean is rapidly warming. 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 it’s role […]
Ocean robots record California’s latest hot year
Using underwater gliders, researchers explain what caused the extremely warm ocean along the coast of California in 2014-2015 and what this might mean for local ecosystems. 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 it’s role in climate. For […]
Can the ocean take the heat?
Things heat up as scientists investigate deeper to find out how much heat the ocean can take. 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 it’s role in climate. For my research I sometimes spend months at sea on […]
