Oil rigs, the food trucks of the sea?

We humans don’t always take time to assess how we impact other environments; more often we survey before we enter the ecosystem, but what happens when we leave? Oil rigs in the North Sea have provided a great opportunity for scientists to start investigating. Click here to find out more!

Listening for Symptoms: A new use for hydrophones in the face of harmful algal blooms

Whales aren’t the only animals hydrophones can detect out in the ocean. In fact, in the near future it might be possible to listen in on animals like scallops and determine if they’re healthy or not. Intrigued? Click here for more!

Loud and Order: How reef fish vocalize to keep schools cohesive

Many animals use vocalizations to send signals to their group, but never before has this been documented in fish, until now. Researchers have found a reef fish that uses vocalizations in order to keep their schools together. Read on to find out how.

Eavesdropping prawns get more than they bargained for

Marine animals living below the surface have to put up with noise generated by human activity. Heavy shipping traffic can bring a lot of noise. How does the common prawn respond?

In the Heart of the Sea: Following the Song of Humpback Whales to Study Migration

Every year, humpback whales journey across the ocean. Using passive acoustics to study whale song, scientists are able to follow the path of humpback whales and learn about their migratory patterns. Read (and listen) to find out more!

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!

Let me cover your ears! We’re going to make some 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!
