A new underwater photography community – Waterpixels!

Many Undercurrent readers will be familiar with the issues surrounding Wetpixel, its travel programme and its owner, Adam Hanlon. 

Concerns about the knock-on impact of its popular community forum were never addressed. New members were not being approved, guest access was closed off and its front page was not updated for some months.

The legendary wreck was discovered off the coast of Cartagena, Colombia, on 27 November 2015, by a team of international scientists and engineers during an expedition aboard the Colombian Navy research ship ARC Malpelo.

The San José, a three-decked galleon approximately 150ft long and armed with 64 guns, sank during a battle with British ships in 1708. It is believed to contain 11 million gold and silver coins, emeralds and other precious cargo from Spanish colonies. Researchers have identified bronze cannons, ceramic and porcelain vases, and personal weapons among the artefacts, confirming the wreck’s identity.

“It’s not often you see snow on the Vesuvius volcano here in the Gulf of Naples, where I live in Sorrento. It soon vanishes due to the mild temperatures. I’ve always wanted to take a photo, and I finally managed to get into the water to do it. During my walk along the Marina Grande in Sorrento, my usual place for winter night diving, the wind pushed a large quantity of jellyfish along the coast. I was lucky to find one that had a small passenger on board, a juvenile imperial blackfish (Schedophilus ovalis).”
