Noise Pollution Stresses Sea Urchins

You may have heard that marine mammals are affected by manmade ocean noise. But have you ever wondered whether smaller critters like sea urchins are impacted? A team led by Vazzana is the first to use coelomic fluid to assess urchin responses to noise.

Ocean Noise Pollution Changes How Fish Grow

The noise we make pollutes natural soundscapes and can impede how animals communicate, move, and behave. Researchers now have evidence that man-made noise impacts fish from the very beginning of their life, altering how they develop and grow. 

Lost in the sound: coral planulae habitat selection affected by boat noise

It can be hard to cut through the noises that surround us and focus on the task in front of us, right? This may not just be a human problem. Noise pollution may be another way human activity is negatively affecting corals.

One person’s noise, is another person’s data

Measuring the heat content of deep ocean waters is critical to understanding how our global climate system works. It is also very difficult to do on a large scale. A group at the University of Georgia recently proposed a new technique to take the temperature of the deep ocean using only ambient noise and passive […]

Rising above the noise

Oceanbites is still “ringing” in the New Year! Find out how in a sea full of noisy fish one can stand out from the crowd. And yes, fish can make noise!

Small boats drowning out natural reef noise?

Don’t you hate when noises interfere with your daily activities and conversations? We create lots of noise in the environment and need to know more about it. Today’s oceanbites focuses on a study of man-made noise on coral reefs. Check it out!

Baleen whales have a bone to pick with noise pollution

CT scans of the skull of a beached whale has helped a pair of researchers figure out how baleen whales hear. Through computer modeling, they found that baleen whales, in addition to using soft tissue in their head like antennas, also use the bones in their skull to pick up sounds from their environment.

Climate Change Is Causing A Stormy Future

A new study verifies a decades-old prediction that tropical cyclones are becoming more intense due to climate change, using a novel, satellite data-driven approach.

Underwater musicians: estimating health of an estuary using sound

Ever hear a snapping underwater? Wonder who is making the sound? Researchers can use sound to take the pulse of an estuary.

Where’s that accent from? Dolphins from different seas talk in different whistles

Dolphins talk to each other by whistling, but whistle sounds vary between seas. What causes those differences in dolphin accents?

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?

Life of the party: Dolphin personalities and social structures

Are you more of a life of the party type person or a wallflower reserved type? Did you ever think that non-human animals, like dolphins, might have similar personality differences? This scientist takes a look at wild bottlenose dolphin populations and why their personality characteristics are important.

Counterintuitive? Fish make more brain cells in water rich with carbon dioxide

Fish continuously make new neurons in their brain. Ocean acidification is harmful for marine life, but can it help fish grow even more brain cells? Scientists say – maybe.

Sounds, Stress, and Stingrays

Have you ever wondered if stingrays can hear noise? Sharks, skates, and rays have multiple sensory organs to help then navigate their environment and hunt for food; for example, jelly-filled pores on their body allow them to sense electric fields in the water. However, less is known about how well these animals can hear. The […]

How do we navigate a climate-changed sea? By getting Inuit perspectives on the map.

Climate change is impacting the waters of Arctic Canada. As ice cover declines, interest in using these routes for international trade and shipping is increasing. However, increasing ship traffic has real implications for the health of the people and wildlife of this area. Inuit communities took part in the Canadian government’s planning process to ensure […]

Protections with a bite: Are toothed whales sheltered by South African Marine Protected Areas?

Marine Protected Areas (MPAs) are often put into place to protect biodiversity and essential fish stocks, but toothed whales are rarely considered when deciding where to put an MPA. As South Africa looks to expand its protected areas, Jean Purdon and her colleagues set out to learn where the toothed whales are living off the […]

Ensuring that coral reefs sound like home

What does a coral reef sound like? The answer is more important than you might think. By playing the sounds of a healthy reef over a loudspeaker, scientists were able to attract a variety of baby fish to settle on a degraded reef, results which show how acoustic interventions are a tool that can be […]

The Sound of (Fish) Music

The ocean contains a symphony of sounds. A new study describes a novel method for capturing the chorus “sung” by fish.

Monitoring the benthos by listening to photosynthesis

Even though the benthos is a largely unseen energy base for marine food webs, scientists are listening to benthic habitats as a novel way to monitor ecosystem health. Read on to learn about how acoustics can capture sounds produced by benthic algae.

Growing a Scientist: Undergraduate Research 2018, part 1

Check out these posts by guest authors Ellie Tan, Samantha Vaverka, Joseph Barnes, and Gibson Levitt about building water quality monitoring systems, toxic algae, and robot kayaks–these students were part of the SURFO program at URI-GSO over Summer 2018, and have some really exciting research to share!
