Harmful algal blooms are common events that occur in coastal waters. In Florida’s Indian River Lagoon, nutrient groundwater runoff initiates massive and highly toxic bloom events. Harmful blooms spell trouble for the environmental health and economic value of the lagoon. How bad has this issue become and what can be done to minimize the severity of future blooms?
Coral reefs populations are declining. Is it possible that we could help restore coral reefs by speeding up their evolutionary processes? Researchers propose new management strategies for aiding reef restoration by accelerating the natural processes of evolution.
The dangerous diet fad among marine organisms is spreading! New study shows corals consume microplastics.
Knowing that a species has low survival rates after encountering a fishing vessel is useful. But knowing exactly what about the fishing process kills that species can result in more effective conservation efforts.
Like the West Antarctica Ice Sheet, East Antarctica is home to glaciers thinning at an alarming rate. The east’s Totten Glacier stores enough water to raise global sea level by 11 feet, similar to projected amounts in West Antarctica. Researchers conducted a study to find out what is causing Totten to melt so quickly. The answer lies beneath the ice.
We owe our hard heads to our invertebrate ancestors.
Geothermal heat harvesting could power the future, so why are we still burning fossil fuels? Maybe because no one has ever laid out a plan like this.
Fisheries managers have begun a shift from attempting to protect individual fish species to protecting entire ecosystems. Marine Protected Areas (MPAs) have been highly successful at conserving important species and habitats like coral reefs. Is it possible to utilize relatively small MPAs to protect the 200-300 fish species that regularly travel long distances? New research suggests this approach may be more promising than we once thought.
Deep-diving ocean drones confirm continued warming of the ocean’s abyss due to Earth’s energy imbalance.
Dolphins and humans are continuously exposed to low levels of various halogenated, persistent manmade pollutants through their diets. In this study, blubber samples from 8 dolphins were analyzed by cutting-edge techniques to find out what’s accumulating in these marine predators. Findings suggest many routine monitoring programs underestimate the exposure of marine mammals to toxins.
Rising ocean temperatures threaten coral reefs, but a new thermal tolerant algae could help.
Jellyfish are commonly thought of as passive drifters in the ocean, but a team of researchers are working to change that. By strapping accelerometers to jellyfish in the field, they have found evidence to show that jellyfish can orient themselves relative to the current around them to help keep their position in the ocean.
Through biogeochemical analysis, researchers found that mercury levels in ancient Pacific Cod bones peaked at a time of deglaciation and sea level rise. Read more about the study, and what it may tell us about future climate change.
Stream water temperatures have increased over the last 51 years in the Chesapeake Bay watershed and are connected to increases in air temperature, latitude, and changes in land-use, causing potential shifts in ecosystem dynamics and stratification.
The Top 5: Highlights and notes from an eventful Benthic Ecology Meeting!
Penguins find a way to balance the extra work of the breeding season while still finding time to go diving to find food.
Currently, spreading dispersants is the most common way to stabilize surface oil after oil spill. These dispersants divide oil into small droplets which are more available to bacteria. However, this application of dispersants is not applicable near the coast and the toxicity of dispersants remains to be studied. Natural granular material could be a more eco-friendly tool in fixing coastal floating oil.
Everyone usually agrees that establishing more protected areas in our oceans will help overfished populations recover. But what if that’s not the whole story? Read on to find out how an increase of lobsters in a British marine protected area has resulted in a higher prevalence of shell disease.
From 2009-2010, the Northeast coast of North America experienced approximately four inches of sea-level rise, quite the departure from the 2.5 mm per year annual average rate of rise. Researchers link this leap in sea-level to changes in Atlantic Ocean circulation and atmospheric pressure gradients. Will extreme sea-level rise events continue to be the exception, rather than the rule?
Can marine life adapt to ocean acidification? Well, first we need to understand if these favourable characteristics (survival under elevated CO2 conditions) are genetically determined and can be passed on to the offspring!
