The most important result of the 2019 season was confirmation that the eastern concentration of largely homogenous ceramics located on an elevated, rocky outcrop to the east of the breakwater and the sheltered channel, was indeed a shipwreck

The survey was carried out by staff from the University of Southampton, Centre for Maritime Archaeology, as part of the Ancient Akrotiri Project, an ongoing collaborative research project on the peninsula conducted since 2015 and led by the University of Leicester.

Survey conducted by divers using underwater scooters, enabled wider coverage of the offshore approaches, identified new finds including numerous stone anchors and what appears to be the remains of a wreck carrying roof tiles, still of uncertain date.

Using sounds of healthy reefs to attract young fish

4 years ago By Sum Won

Healthy coral reefs are full of sounds of life—with the whistles, pops and grunts of fish, the crackle of snapping shrimp, etc. These sounds travel out through the ocean currents, and “advertise” to young fish to come and settle down at this particular reef ecosystem.

However, when reefs are degraded or dying, the environment falls silent. Literally.

As a result, young fish do not find their way to such reefs, and this exasperates the reef's dire situation.

It was a beautiful day in Indonesia’s Banda Sea. Richard rolled back into the warm waters and swam over to join his wife, Florence. After exchanging signals, they descended together, heading for a patch of bright yellow sea fans on the reef wall at 30m, where their guide had promised to show them pygmy seahorses. The guide was already there below, searching for the elusive little creatures.

It appears that the presence of boats has an impact on the social behaviour of humpback whales.

Humpback whales less sociable in presence of boats

4 years ago By Sum Won

After studying humpback whales off Queensland's Peregian Beach, researchers discovered that the whales’ ability to communicate and socialise is adversely affected by the noise and presence of boats.

In some cases, the mammals’ communication range is reduced by a factor of four.

"It appears that groups of humpback whales tend to socialise much less in the presence of vessels—in this study, mostly small fishing boats—compared to when there aren't any present," said Rebecca Dunlop from The University of Queensland's Cetacean Ecology and Acoustics Laboratory.
