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 group of manmade molecules, the organophosphate esters, in snow, seawater, and air from the remote North Atlantic and Arctic Ocean.

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!

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?
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!
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 of change as a result?
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.

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.
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.
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.
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!
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 squid prey. Find out more in today’s oceanbites.
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.
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.
Welcome to oceanbites!
The goal of oceanbites is to make cutting edge research in the ocean sciences accessible to all. oceanbites will also highlight classic, seminal research papers, and feature op eds about current issues in research.
