The 1974 film “Jaws” immortalized the Great White but also did more damage to the image of the Great White Shark than they could ever do themselves. Despite all the fear and celebrity, very little is known about these aquatic behemoths. Scientists who have studied Carcharodon carcharias (jagged tooth) aren’t even sure how they reproduce. […]
The British Sub-Aqua Club (BSAC) has published its Annual Diving Incident Report for 2014. The 2014 report records a total of 216 incidents. BSAC have monitored and reported on diving incidents since 1964. Their report contains both details of UK diving incidents occurring to divers of all affiliations, and incidents occurring world-wide involving BSAC members. […]
An underwater robot has enabled researchers to produce the first detailed, high-resolution 3-D maps of Antarctic sea ice. Scientists from the UK, USA and Australia say the new technology provides accurate ice thickness measurements from areas that were previously too difficult to access. Scientists use a range of technologies and techniques to measure sea ice […]
In the last 60 years the fishing industry have caught nine out of every ten large fish. That’s only 10% of large fish like tuna, cod, swordfish and halibut remaining on the planet. International fleets still pursue what is remaining. According a 2014 report by the United Nations Food and Agriculture Organization, over 90% of […]
Australia has declared that it will ban dumping of sediment in the marine park area of the Great Barrier Reef, but not in the entire World Heritage Site. This matters because, according to environmental pressure group Fight for the Reef, in recent years 80% of dumping has been in World Heritage waters just outside the […]
Along with her husband Shaun, Beth Tierney is co-author of the popular Diving the World. Jill Studholme interviewed her for SCUBA News. What makes your book different from other books about diving around the world? There are two principals we have stuck to ever since the first edition. Right from the start, we asked other […]
Male crustaceans avoid being completely feminised by pollutant-contaminated seawater as they “lock down” their maleness. New research by scientists at the University of Portsmouth has shown that crustaceans turned partially into females but retained a core of masculinity, and they may have learned how to do it after evolutionary battles with parasites. The research is […]
Survey of 9000 people finds that people around the world want to eat sustainably fished seafood.
Marine conservation group Oceana finds amazing array of marine life in Canary Islands expedition, from shallows to down to 1000m. Using ROVs (remotely operated underwater vehicles) as well as scuba divers to shallow depths, they documented large colonies of deep-sea white coral, crystal aggregations of sponges, dense forests of black corals, oceanic puffers, giant foraminifera, carnivorous sponges and sharks, as well as many other biological communities and species in the south of the El Hierro Island.
SCUBA divers underestimate the amount of life in heavily-fished areas, a study suggests. Scientists from Australia compared fish counts by SCUBA divers—who produce noisy bubbles—and divers using silent rebreathers. They found little difference in counts between the two in Marine Protected Areas (MPAs), where the fish weren’t frightened of the divers. In more heavily fished […]
