Instead of wearing earplugs at a rock concert, imagine you could simply tune a dial inside your ears to lower the volume and protect your hearing. In a new report published in Integrative Zoology, researchers have discovered four whale species and dolphins can do just that. This could potentially shield the animals from navy sonar and oil drilling, linked to at least 500 marine mammal deaths since 1963.
“Experience is what you get when you don't get what you want.” It is an old and well-worn phrase, but is it true?
Aqua Lung launched their first modular buoyancy control device - the minimalistic 'Outlaw' - at DEMA.2016.
Most years, Southern California on the US west coast is the site of a special marine life aggregation, treating locals to one of the most unique dives in the world. Hundreds of thousands of market squid (Doryteuthis opalescens) swim into recreational dive depths to mate and lay an expansive canvas of egg baskets (collections of eggs) across the sandy substrate.
The lead researcher, Kye Adams, a PhD student at the University of Wollongong, said that shark fishermen should be made aware of the danger of inducing abortions in pregnant sharks, rays, or skates. So far, the loss of the young aborted by fished sharks has been ignored by both science and fishermen.
Adams said, "It's quite prevalent across a lot of species and also seems to be not well known by both researchers and recreational fishers. "They don't realise these events are abortions, they think they are witnessing a natural birth."
The (34,000 Swedish Krona) package consists of a SE7EN E-module, two HP-sensors and a HUD.
The deadline for this upgrade is 24th December 2017 and it cannot be combined with any other offers. The old MKVI e-module must be returned to Poseidon and the owner will also need to either buy a M28 or a Paddle with a can connector.
Poseidon has also confirmed that there will be a minor upgrade for current SE7EN owners so that their rebreathers are solid state sensor ready.
The Leadership Rescue Workshops are open to any certified dive leader, including divemasters, assistant instructors and instructors from other agencies.
The workshop is designed to teach the most effective, state-of-the-art diving rescue techniques in a rigorous three-day program conducted by Course Directors Walt “Butch” Hendrick (NAUI 1724) and Andrea Zafares (NAUI 10533) of Team LGS, the most globally recognized authority in diving rescue and public safety diver training and education.
Admittedly, the idea of protecting seagrass is not as “glamorous” as protecting the rainforest, but this marine vegetation is essential to both marine life and humans. A new study by scientists from Cardiff University, Swansea University and Stockholm University, and published in the Fish and Fisheries journal, highlights the global importance of seagrass to fisheries.
“Wherever you find seagrass and people, there is most certainly fishing,” said Dr Leanne Cullen-Unsworth, from Cardiff University’s Sustainable Places Research Institute.
We’ve all seen those huge schools of fish that move as one and coordinate their movements so perfectly. New research has come up with a way to map the chain of direct interaction in such schools of fish, discovering that the fish pay attention to one or two of their neighbours at a time when the school moves as a group.
The initial purpose of the bill, called The Access for Sportfishing Act of 2016, was to prevent national parks from trying to protect fish in waters within state jurisdiction, and in June, Senator Bill Nelson, from Florida, added the ban on shark feeding diving in federal waters. The bill specifies that it is all right to feed sharks for the purpose of killing them, but not if you want to watch the shark. Thus it is the motive for the act of shark feeding, rather than the act itself, that is at issue.
The Twelfth Session of the Conference of the Parties to the Convention of the Conservation of Migratory Species of Wild Animals (CMS CoP12) was held in Manila, Philippines, between October 23 and 28. It resulted in added international protection for sharks and rays and several other migratory species, and the decisions were endorsed by the 90 governments attending.
Project Baseline’s team conducted over 100 video transects of coral reef and benthic habitats of the Great Astrolabe Reef in Fiji, one of the largest barrier reefs in the world, to compile baseline reports in order to effectively monitor the health of the reef.
