‘Out of Sight’ Can’t Mean ‘Out of Mind’

Surface marine debris and microplastic pollution has gotten more attention recently—which is great—but there’s another garbage problem we are only starting to get a handle on. Deep in the dark, discarded items litter the sea floor, like dust-bunnies swept along by currents and collecting at rates previously underestimated. Andrea SchlunkI am a former PhD student […]

Rainwater floods an ecosystem of productivity

Phytoplankton fuel the productivity of the marine ecosystem. They need nutrients to carry out their cellular functions and, in most estuaries, nutrients can come from riverine outflow. However, how do phytoplankton receive nutrients in regions where freshwater river inflow does not exist? Scientists observed the influence of rainfall on phytoplankton community composition in Sydney Harbor, […]

Far-Flung Relatives: A seabird’s story of population fragmentation

The Peruvian diving petrel was once abundant along the Pacific coast of South America. These days, though, only seven breeding colonies dot the coastline, separated by dozens of miles. Conservation efforts were initially aimed at the species as a whole, but a recent study has uncovered evidence that calls into question how effective those efforts […]

The Gulf of Mexico Triangle: Assessing Movements of Large Pelagic Fish Across Multiple National Boundaries

Pelagic predators or difficult to manage due to their vast migrations through through multiple countries jurisdictions and international waters. In order to effectively manage these species multinational agreeements are required. However, collecting movement data for species that travel long distances is difficult to collect. Here, researchers look at the movements between countries of 8 species […]

Tigers, Bears, and Sharks, Oh My! Who’s the deadliest?

Bornatowski, H. et al. Geographic bias in the media reporting of aquatic versus terrestrial human predator conflicts and its conservation implications. Perspect Ecol Conserv. (2018). https://doi.org/10.1016/j.pecon.2018.12.004   Depends on where you live. Where humans and large animals meet, the results can be disastrous. While few conflicts with wild animals result in death, they can have […]

Citizen Science, Oh My!

To understand ecosystem level changes, it is important to monitor an ecosystem over a long period of time. However, long-term funding can be limited, especially during times of economic hardships. How do researchers carry out long-term ecological studies in place where sustained funding is unavailable? Read this article to get a glimpse into citizen science, […]

Hawksbills in hot water? Temperature and Precipitation Impacts on Hawksbill Sea Turtle Nests

Climate change is already having effects on sea turtles. All seven species of sea turtle are dependent on temperature for habitat selection and physiology. The impacts of temperature and moisture on hatchling development have real long-term impacts on marine turtle populations. Matthew LarsenI am a second year master’s student at Coastal Carolina University in the […]

Economically vital Blue Crabs having a hard time dealing with marine hypoxia and acidification

Tomasetti SJ, Morrell BK, Merlo LR, Gobler CJ (2018) Individual and combined effects of low dissolved oxygen and low pH on survival of early stage larval blue crabs, Callinectes sapidus. PLoS ONE 13(12): e0208629.    Blue Crab is the 5th most valuable fishery in the US. Known as Callinectes sapidus throughout its range, the Blue Crab […]

Baby come back: capture-induced premature birthing in elasmobranchs

Capturing pregnant elasmobranchs can induce stress-related abortions. Read more to understand why and what can be done to prevent this! Aditi TripathyHello! I am an undergraduate student majoring in Marine Biology with a minor in Acoustics at the University of Rhode Island. I am a science geek to the core, and my research interests lie […]

Can we build a multisensory shark repellant?

Human-shark interactions don’t always end well on both sides. Is it possible to build a shark repellant that can keep both humans and sharks safe by using information about sharks’ sense of sight and hearing? Read more to find out! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of […]

Beyond word of mouth: How local knowledge can fill fisheries data gaps

How can we accurately assess the extent of population declines in marine organisms? Read on to find out how local and traditional knowledge can inform future fisheries management by recounting past experiences. Katherine BarrettKate is a 3rd year PhD candidate in the Biological Sciences Department at the University of Notre Dame, and holds a Masters […]

Wake up and smell the marine awareness…on social media?!

Close your eyes and imagine your favorite beach, or a memorable coast you have visited, completely free of litter-that’s right, no plastic bottles, no garbage, no microplastics, no wandering potato chip bags. Is this vision possible? Take a moment, or 3, and see what you can do to reduce marine pollution! Katherine BarrettKate is a […]

Does long term SCUBA diving affect shark behaviour?

What happens when SCUBA divers and sharks mix? Do divers scare off sharks or attract them? 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 working at the Smithsonian Institution’s National Museum of Natural History in Ocean Education.

Tarballs invading our coastlines: Ghosts of oil spills past

We live in a world that is torn between reliance on fossil fuels and renewable energy. Although we have made great strides towards increasing wind and solar energy, the ghosts of oil spills past are washing up on our shorelines. Katherine BarrettKate is a 3rd year PhD candidate in the Biological Sciences Department at the […]

Public Perceptions of Aquaculture Show Lack of Ocean Literacy

Article: Froehlich HE, Gentry RR, Rust MB, Grimm D, Halpern BS (2017) Public Perceptions of Aquaculture: Evaluating Spatiotemporal Patterns of Sentiment around the World. PLoS ONE 12(1): e0169281. doi:10.1371/journal.pone.0169281 Aquaculture is one of the fastest growing industries in the world. A 2014 report by the UN-FAO estimated global freshwater and marine farming to constitute 44% of all […]

Protecting Our Fish and Birds by Protecting Their Wetland Homes

Wetlands are the link between land and water, and are some of the most productive ecosystems on Earth. They need our protection, for the commercial fisheries we depend upon, for the recreational opportunities they provide us, and for the benefit of the species that use them. Zoe GentesZoe has an M.S. in Oceanography and a […]

‘The conservationist is ready to see you’: triaging marine ecosystems in times of climate change

Climate change affects ecosystems worldwide, but how do conservationists decide which of planet earth’s ecosystems are most in need? Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.

Small MPAs: the new all-you-can-eat buffets?

Marine Protected Areas (MPAs) are a popular conservation tool and are in many situations very effective. Unfortunately, as with many plans, there may be some unintended consequences, as seen in the case of small MPAs in Fiji, where they appear to have attracted corallivorous crown-of-thorns sea stars (Acanthaster spp.).

Fisheries and Food Security

Fish have provided sustenance for millions of people, but in a world where stocks are rapidly depleting, what are the consequences of trying to save and rehabilitate their populations? Andrea SchlunkI am a former PhD student from the University of Rhode Island, having discovered my love of teaching and informal science education in part through […]

Working with the coast

The coast is very dynamic and at the constant mercy of wind and water energy. Often times, humans will try to control the coast by constructing seawalls and groins. Such projects have major impacts on sediment transport that can affect natural ecosystems and recreational beaches. Read here about a group of scientists who sought to […]
