ScienceDaily (July 11, 2011) Scientists from British Antarctic Survey (BAS) have discovered previously unknown volcanoes in the ocean waters around the remote South Sandwich Islands.

Using ship-borne sea-floor mapping technology during research cruises onboard the RRS James Clark Ross, the scientists found 12 volcanoes beneath the sea surface -- some up to 3km high. They found 5km diameter craters left by collapsing volcanoes and 7 active volcanoes visible above the sea as a chain of islands.

Fujifilm announced the new Remora Slave Flash Kit that is compatible with Fujifilms full range of digital compact cameras and underwater housings. The Remora Flash is not only suited to daytime diving, but its performance is also essential during night dives with a powerful guide number of 20. It also has an extra wide angle flash beam angle of 60 degrees so a bigger area can be illuminated underwater to meet the needs of both macro and wide-angle photography.
