WHOI: New Discovery Reveals Sharks May Detect and Produce Sound
of the genus produce similar sounds. If these sounds come from jaw snapping, other sharks with strong crushing jaws may be able to do the same. While Nieder’s work has shifted to using acoustic techniques to enhance coral larval settlement in reef restoration efforts, she hopes to return to New Zealand to unravel exactly how these sharks make their sounds—and whether other local shark species might also have voices waiting to be heard.
Sewage Contaminates British Waters
warmer water, the right sea depth and abundance of nutrients they believed would help mussels grow faster. It had to be far enough offshore to avoid runoff, but with some protection to limit the swell of the sea.They settled on Lyme Bay after visiting similar sites around Britain, Europe, China and New Zealand and spent seven years securing planning and regulatory approval - without knowing whether their hunch would pay off.Eleven years on, the farm produces about 3,000 tonnes of mussels a year and the Holmyards hope to hit 10,000 to 12,000 tonnes once it is completed.John Holmyard, who runs the business

Ice Navigation: Every Voyage is Different
It’s late in the season so Captain Duke Snider, sailing on a resupply voyage from New Zealand to Antarctica, is expecting virtually no sea, just glacial ice.Snider has been an ice navigator for decades, and he has seen the ocean change, not just here in the polar south, but in Arctic waters as well.“Variability is much greater than in the past when we could expect an ice breakup to occur within a calendar week, year after year, whether it was the Arctic or the Antarctic,” he says. “Now, you have to look at each year individually and be more alert than ever before, particularly

Canadian Shipwreck Hunters Unleash New Tech
. However, precision in locating and identifying these submerged targets is a persistent challenge, especially due to the unique conditions the pair face on their regular expeditions.Despite equipping ‘Best Kind’, Sid’s Farmont 70 expedition yacht with a multibeam made by Aukland, New Zealand-based manufacturer WASSP, he found room for improvement when in order to reach the level of detail required for distinguishing remnants of wooden shipwrecks, many of which had deteriorated after decades under the sea. The unpredictable three-directional swells and constant movement of his boat

Scientists Reconstruct Impact of Seafloor Volcanic Eruption
activity and its footprint on the offshore ecosystem provides data to more readily predict the frequency and severity of events, which is essential to saving lives and cultures.”The international team included scientists from the United Kingdom, Chile, the United States, Italy, Malta, and New Zealand and was co-led by Dr. Rodrigo Fernandez of the Universidad de Chile, Dr. Rebecca Totten of the University of Alabama (United States), and Dr. Giulia Matilde Ferrante of the National Institute of Oceanography and Applied Geophysics (Italy).

Divers Recover Video Equipment from Mike Lynch’s Sunken Yacht
, a coast guard official in Palermo, said the divers were using a hyperbaric chamber that allowed them to make repeated dives of up to 40 minutes.The coast guard took underwater images with a remotely operated vehicle that will help draw up a plan to salvage the yacht.Three crew members, including New Zealand captain James Cutfield, are under investigation for manslaughter and shipwreck.
