Seaweed antioxidants protect fish too

A new study suggests that feeding fish small amounts of antioxidant-rich seaweed can protected them from environmental challenges. 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 […]

Toxic living: finding the right home for sulfur-oxidizing bacteria

Hydrothermal vents are hot, dark, and toxic environments. But to sulfur oxidizing bacteria, they’re home. 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? I spend my non-science […]

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 […]

Minimizing bycatch by maximizing incentives

What’s the best way for fishermen to avoid catching the wrong type of animal in their nets? According to this paper, there’s the way we’re doing it now, and there’s a way that allows for more flexibility and more compliance. Read on to find out more about preventing bycatch through incentives! Erin McLeanHi and welcome […]

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 […]

BAD BOYZ 2.0. Emerging environmental contaminants

Our generation is facing environmental challenges not only from commonly-known contaminants, but also emerging ones, which have been lurking in the shadows until recently. Check this week’s post to know more about these (sometimes surprising) pollutants, and their effects! Prabarna GangulyI’m a fourth year PhD candidate in the Department of Psychology at Northeastern University. My […]

New Nitrogen in Town: Nitrogen Deposition on the Open Ocean

Life in the ocean depends on a variety of nutrients, an important one being nitrogen. Phytoplankton, at the bottom of the oceanic food chain, require it to photosynthesize. Burning fossil fuels releases nitrogen into the atmosphere, and a portion of it is known to settle into the ocean. Has the ocean started to show signs […]

The Once and Future Ocean

A newly collected sediment core from the Labrador Current gave Dr. Harunur Rashid a glimpse of the ancient ocean. What he saw might help inform our predictions of the future climate. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the Jaffe Laboratory for Underwater Imaging focuses on developing […]

Can you keep me safe? What can MPAs do for Sharks

Article: White, T. D., Carlisle, A. B., Kroodsma, D. A., Block, B. A., Casagrandi, R., De Leo, G. A., … & McCauley, D. J. (2017). Assessing the effectiveness of a large marine protected area for reef shark conservation. Biological Conservation, 207, 64-71. What is an MPA? What do you think about when you hear the word MPA? […]

An arsenic surprise: How our buried past will catch up with us

Global sea level is expected to rise 0.8 to 1 meter by 2100 and may release arsenic trapped in soil. Researchers investigated how this arsenic release would impact the biogeochemical cycling of coastal water systems as they are inundated with water due to sea level rise. Victoria TreadawayI am a PhD candidate at the Graduate […]

Metal fingerprints enhance recycling

The bioaccumulation of bioactive metals in top predators plays a key role in the recycling of nutrients in HNLC zones of the Southern Ocean. Furthermore, the concentration of bioactive metals can be used as a ‘fingerprint’ to identify the appropriate trophic level of a species. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, […]

Current connections: how far away coastlines influence marine reserves

A research team used a state-of-the-art model to map how four remote Marine Protected Areas are connected to the surrounding oceans, and how human activities are impacting them from afar. 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 […]

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 […]

Using seabirds to study squid

How do scientists track fast swimming squid in the remote and vast open waters of the Southern Ocean? Probably not in any way you’d expect. They use squid predators, specifically a seabird—the wandering albatross—to find the squid for them. These albatrosses are outfitted with some very cool technology to bring the researchers information on their […]

Happy World Oceans Day!

Happy World Oceans Day! A day to celebrate and appreciate the fantastic oceans, while also raising awareness of the importance of minding and minimizing our impacts. 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 in my neophyte career, including […]

Paleoshorelines: Time capsules of the ocean’s ancient shorelines

In celebration of World Ocean’s Week, let’s take a moment to think about how far we have come in discovering the history of the oceans. Katherine BarrettKate is a 4th year PhD candidate in the Biological Sciences Department at the University of Notre Dame, and holds a Masters in Environmental Science & Biology from SUNY […]

The oil droplet is quite terrified

Oil Spill Snorkels: Eating oil, breathing electrons, saving the world?

Oil spills are not great for the environment, but some bacteria thrive on eating oil. Scientists have been researching ways to use these natural oil degrading bacteria to clean up oil contaminated areas. A group in Italy adapted graphite rods to encourage marine mud bacteria to degrade oil more quickly. They call this the “Oil […]

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 […]
