As far as the eye can(‘t) see: climate change may impact vision

Seawater is getting warmer, more acidic, and depleted of oxygen, and those shifts are causing animals serious problems: decreases in reproductive ability, increases in predators, and changes to habitats. A new review out of UC San Diego zooms in to investigate the effects of deoxygenation on a small organ with a big impact: the eye. […]

The answer to starvation? Diversity

Photosynthetic microorganisms can’t go it alone, so they succeed by playing host to a diverse array of microbial partners 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 are they doing there? […]

Sea snakes join the dark side to cope with pollution

Black sea snakes are more common in contaminated sites. Why? 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 metabolic responses of Fundulus killifish to intermittent (diurnal) patterns of hypoxia.

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 […]

Futurama: Building scenarios to sustain oceanic ecosystems and fisheries

Can we envision and safeguard the future of oceans and fisheries? Read on to learn about how experts are coming up with ways to think about the future, and our need to be prepared for all possibilities!

Wandering copepods can’t find their way home in acidic oceans

Journal source: Smith, J. N., C. Richter, K. Fabricius, and A. Cornils. 2017. Pontellid copepods affected by ocean acidification: A field study at natural CO2 seeps. PLoS ONE 12 doi: https://doi.org/10.1371/journal.pone.0175663. Introduction Ocean acidification (OA for short) is a topic that seems to be receiving increased attention, and if you’ve scrolled through some recent Oceanbites posts, […]

New insights into old events using marine sediment

We talk a lot about what the ocean is doing, but what can it tell us about land? Here, we discuss a study where scientists used modeling and marine sediments to determine how African climate changed in the Saharan! Laura ZinkeI am a PhD student studying sediment geomicrobiology at the University of Southern California. My […]

Deep Secrets of the Scalloped Hammerhead Shark

Sharkbites Saturday is thrilled to feature a guest post by Mark Royer, a Ph.D. Student from the Shark and Reef Fish Research Lab at Hawai’i Institute of Marine Biology, led by Carl Meyer and Kim Holland, two of the most distinguished shark scientists in the world. Mark shared his current PhD dissertation research with us, along with some of […]

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 […]

Carbon Dioxide In and Methane Out: the Surprising Chemistry of an Arctic Methane Seep Field

The bad news: coastal frozen sediments in the Arctic are melting and emitting methane, a potent greenhouse gas, into the atmosphere. But there is good news: this methane release is accompanied by significant carbon dioxide absorption by seawater, enough to result in a net cooling effect for the atmosphere. Find out how these methane seeps […]

A Day in the Life of a Shark Intern

Karla HaiatI’m an Undergraduate student at University of Rhode Island majoring in Ocean Engineering and Marine Biology. I’m interested in the intersection between technology, biology and […]

Connecting production to glacial meltwater

As sea-ice disappears, many scientists predict that primary production will increase in high latitude regions. A Danish group adds some nuance to this prediction based on a recent study off the coast of Greenland. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the Jaffe Laboratory for Underwater Imaging […]

Can you hear me now? Investigating sound across the Atlantic Ocean

The ocean is full of sounds, ranging from marine mammal conversations to man-made noises used to investigate the seafloor.  Ocean noise pollution makes it hard for marine mammals to communicate with each other. Read more to learn how scientists measure sound in the Atlantic Ocean. Victoria TreadawayI am a PhD candidate at the Graduate School […]

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 […]

The elephant in the oxygen minimum zone

When people think of the animals that inhabit the deep sea, they think of the fascinating, alien-like creatures like the anglerfish or the colossal squid. But, there are other animals that are able to inhabit parts of the deep ocean for a short amount of time, like the elephant seal. Why do they go down […]

Heat flux from active crust

Researchers generate a high resuliton 3-D model of the subseafloor to learn more about what controls heat flux from the Juan de Fuca Ridge! Their findings provide evidence that support hypotheses about the impact of magma replenishment and permeability on heat flux. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine […]

Builders or Opportunistic Squatters? Invasive Species Drives Ecosystem Change on Georges Bank

See article here: https://link.springer.com/article/10.1007/s10530-017-1517-y Tunicates are underappreciated seafloor animals. Living sedentary lives and resembling some kind of marine slime, they don’t usually make it into headlines or flashy ocean documentaries. They are, however, important components of marine ecosystems (super cute ones too, like these bright blue ones), building bottom habitats and providing food for a […]
