Fish are rebelling. What’s the cause?
Derelict fishing traps, or DFTs, are abandoned traps that may still be actively capturing marine organisms, in a phenomenon known as “ghost fishing.” In this study, a group of scientists put together a qualitative assessment on the ecological and economic impacts these traps may be having on coastal ecosystems throughout the United States.
Tropical cyclones are escaping the hot tropics and intensifying closer towards the poles. The apparent expansion of the tropics helps us to understand why.
While Marine Protected Areas do a great job of preserving essential marine habitats, and decreasing fishing pressure, they may not be the best solution for the seahorse population.
We don’t traditionally think of our ships making noise that will disrupt animal behavior, but this study, looking at eels antipredation behavior under noisy and quiet conditions – shows that animals can be negatively affected by noise pollution.
Multiyear sea ice formation in the Arctic Sea uptakes microplastics from seawater, effectively acting as a sink for these man-made particles. Melting sea ice, as a result of climate change, threatens to release these microplastics back into the ocean with unknown implications for the environment.
Recent findings from the north east Pacific may have solved a major controversy in scientists’ understanding of nitrogen loss from the ocean. Researchers developed a model to predict the contributions of denitrification and anammox to total nitrogen loss and confirmed the model predictions using laboratory studies.
If you are a fish like the California grunion, environmental cues are going to play a role in determining whether you are a male or female fish. If the environment is colder, you are more likely to be female; if the environment is warmer, odds are you’ll be male. But it seems that temperature isn’t the only environmental cue influencing sex. Researchers have found that photoperiod, or the duration of sunlight during the day, influences sex ratios in some fish.
Injured squid are more vulnerable to attack from predators but stepping up their defensive behaviors gives them a fighting chance. Long term pain sensitivity makes this possible.
Pharmaceuticals, corrosion inhibitors, biocides and stimulants are some of the most frequently detected micropollutants in the aquatic environment. They are toxic, bioaccumulative and hard to degrade. They can pose risks to the local ecosystem or even human 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!
From the early 1990s on, the Earth has been experiencing a global warming hiatus, where the post-industrial warming trend has effectively come to a stop. Recent research has implicated strengthening Pacific trade winds as the cause of the warming hiatus. New evidence suggests the mechanism triggering the unprecedented acceleration of Pacific trade winds has its origins in the Atlantic Ocean.
Seafood mislabeling is a big problem for both consumers and fisheries management. Using genetic data and mercury concentrations, scientists figured out how frequently store-bought Chilean sea bass was swapped. Results indicate seafood substitutions can mean very different concentrations of mercury in your meal.
A large portion of the North American Grizzly Bear population call Western Canada home. The diet of these bears ranges from berries to mammals, and every year in the fall, coastal bears consume copious amount of Pacific salmon. This study investigates hair samples from Grizzly Bears and how they can be used to reflect dietary changes in mercury consumption.
As a novelist writing about oceanography, I spend a decent amount of time parsing scientific studies. Over the past several years my vocabulary has expanded to include terms like band saturation, turbidity currents, and foraminifera—phrases and words that had not existed in my wildest dreams when I first started writing. I’ve relied on studies and […]
Scientists found an octopus that guards its eggs for the longest period ever recorded. The super mother was filmed for 53 months and has produced the largest and most developed hatchlings known to date.
