Cold Water Conundrum: How does unusually cold water affect fish growth?

With the threat of climate change ever present, many of us focus on the negative effects of unusually warm water on fish species. But, can abnormally cold water also hurt fishes, and can it hurt different fishes in different ways? Francesca GiammonaI am a PhD candidate at Wake Forest University, and I received a B.S. […]

Life in Plastic: 14 Million Tonnes of Microplastics Likely on Sea Floor

The deep-sea floor has always fascinated scientists and ocean lovers alike with its mystery and wonder. For the first time ever, scientists have estimated the amount of human-made plastics on the seafloor, and it will shock you. Elena GadoutsisI have always been happiest in nature – exploring forests, traveling to the ocean, or working with […]

Shark Smarts: Can associative learning change shark behavior?

We all know that sharks are excellent hunters, but can the instinctual predatory mind of one of the ocean’s apex predators be influenced by the fishing actions of humans? Can sharks learn to feed differently based on human presence? Francesca GiammonaI am a PhD candidate at Wake Forest University, and I received a B.S. in […]

Of Wildfires and Oceans

Wildfires are all over the news, from California to Australia, but do these terrestrial events have any impact on ocean ecosystems? Is it possible that wildfires can cause massive coral die-off across reefs? A research paper from 2003 provides some insight into these questions, and points to a need for more studies on the links […]

On the case: Scientists use many sources to find the culprit in kelp disappearance

The extensive decline of the Great Barrier Reef has received a lot of press attention in recent years, yet reefs aren’t the only down-under ecosystem struggling. In a recent paper in Estuaries and Coasts, researchers Carnell and Keough from the University of Melbourne and Deakin University have reported an equally alarming decline in kelp forests […]

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 received my B.S. Marine Biology with a minor in Acoustics at the University of Rhode Island. Currently, […]

A Whale Shaped Needle in a Ocean Sized Haystack

Sperm whales are very large, but they can still be tricky to find in the ocean! These researchers combined several data sets, from centuries old whaling records to modern automated location recording, to determine the locations off the southwest Australia most suitable for sperm whales, so policy makers can plan to protect these animals and […]

Seagrass Invasion! Tunicates colonizing seagrass beds impact plant and animal community

Seagrass habitats worldwide are in decline due to a number of factors. What happens when an invasive species comes on the scene to add to the stressors affecting seagrasses? Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work in southwest Florida, contributing […]

Growth of a deep-sea predatory fish is affected by surface current strength

A deep-water predatory fish is found to have faster growth rates when productivity is enhanced by the Leeuwin Current along the Southwestern coast of Australia. Lis HendersonI am studying for my doctoral degree at the Stony Brook University School of Marine and Atmospheric Sciences. My research addresses fisheries and climate change in the Northwest Atlantic. […]

How sea turtles with backpacks can help establish highways for ocean health

It is a big scary world out there if you are a migrating ocean animal. However, data-generating backpacks worn by sea turtles can help delineate corridors linking MPAs for added protection! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently working at the […]

We didn’t start the fire!… that changed the southeast Australian landscape 44 thousand years ago

A sediment core suggests that the large ecosystem changes that occurred in southeastern Australia were caused by the extinction of large grazers, not human-controlled fire use, which caused fire-prone forest vegetation to overtake the grassy landscape. Kari St.LaurentI received a Ph.D. in oceanography in 2014 from the Graduate School of Oceanography (URI) and am finishing […]
