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!

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.

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.

‘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?

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?

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 quantify just how much of an impact seawall and groin development had on a section of coast in southeast India.

Hard Coral or Macroalgae? Coral Reefs May Have Another Option

Most of the time coral reef communities are discussed, it seems the focus is whether they’re dominated by hard coral or algae. It turns out there may be other possible outcomes for reefs in the future. Find out more in today’s oceanbites!

Paradise Loss: How humans are impacting coastal reef communities

Humans are drawn to beautiful beaches and warm water, and with us come the conveniences of modern day civilization. While life may be flourishing in the shops, restaurants and luxury hotels, this development is taking its toll on the fragile reef community just off shore. Although reefs may appear healthy to the naked eye, researchers have discovered coastal development impacts their biological diversity, and this may be an indication of more serious, long-term damage.

Mangrove Takeover Impacting Salt Marshes

Mangroves are encroaching on salt marsh habitats worldwide, but what does this change in plant community mean for the plants, ecosystem processes, and other inhabitants of these areas? Find out a bit of the answer to that question in today’s oceanbites!

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 other scientists can save time searching for them.

The long and winding Eel migration

A glimpse of the thousands’ mile migration of the European eel shows it’s anything but straightforward.

From Wastewater to Seahorses to the Medicine Cabinet

Pollution of metals could be getting into the tissue of seahorses–the very tissues that are used to make a special Chinese medicine. Now scientists fear that the metal pollutants could harm the patients who take the medicine. Read more to find out what they learned about the accumulation of metals in seahorse tissues.

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?

New Model Evaluates How Coastlines in the Northeast United States Respond to Sea Level Rise

Some coastlines are more resilient to sea level rise, whereas others just plain drown. A new study by geologists at the United States Geological Survey evaluate how coastlines along the northeast United States will respond to sea level rise.

Rip Rap Sill: The Best of Both Worlds

The hybrid shoreline stabilization method called rip rap sill combines rock structures with native vegetation. This study found that fish biodiversity and abundance in rip rap sills was more similar to a native marsh than a built rip rap.

Sea Lions and goose chases – a day at the Marine Mammal Center

I spent a morning learning about the Marine Mammal Center at Moss Landing in California, helped with the intake of a sea lion, and went out on a call with the team.

To I.D. Debris: LIDAR as a tool to identify trash on the beach

Scientists may have a new option for figuring out how much debris litters our beaches and what it all is! Find out more in today’s World Oceans Day post on marine debris!

Room to Grow

When natural ecosystems are destroyed from anthropogenic development there exists a common notion that a replacement can be replanted somewhere else. One has to wonder though; what if the ecosystem destroyed cannot be replaced into the same role it once had. Scientists investigate if planted mangroves in the Philippines change the natural mangrove areas surrounding the restoration area, and to determine if there are differences in species diversity between planted and natural systems.
