Scuba News..because we can’t be underwater all the time
Archive for May, 2009Protecting the oceans makes economic senseFriday, May 29th, 2009
Protecting the oceans through marine protected areas can provide higher and more sustained income through tourism and controlled fisheries than continued exploitation. This is the result of IUCN's new compilation of case studies about the economic benefits of marine protected areas, launched on World Biodiversity Day at the 2nd International Marine Protected Area Congress.
Unmanned underwater vehicles to move like animalsThursday, May 28th, 2009
Unmanned underwater vehicles (UUVs) could eventually turn on their axis like a shark or crawl along the seabed like an octopus - that is, if a UK research programme is successful. An engineering team led by Gwyn Griffiths of the National Oceanography Centre in Southampton (NOCS) will spend the next three years researching ways of improving the agility and manoeuvrability of UUVs by taking inspiration from marine animals.
Basking shark mystery solvedMonday, May 25th, 2009
Once thought of as a strictly cool-water species, basking sharks migrate to deep tropical waters each winter, according to research published in the June 2009 issue of journal Current Biology.
Dolphins seen trying to kill calfSunday, May 24th, 2009
Adult tucuxi dolphins have been seen trying to kill a newborn calf of their own species. It is the first record of these dolphins attempting infanticide. Although common in many mammal species, infanticide is rarely recorded among cetaceans, the group of animals that includes whales and dolphins.
Endanged right whales found where they were thought extinctSaturday, May 23rd, 2009
Using a system of underwater hydrophones that can record sounds from hundreds of miles away, a team of scientists has documented the presence of endangered North Atlantic right whales in an area they were thought to be extinct. The discovery is particularly important, researchers say, because it is in an area that may be opened to shipping if the melting of polar ice continues, as expected.
Manage corals and minimise climate changeThursday, May 21st, 2009
A better assessment of the threats to coral reefs along with improved management will give corals a much higher chance of survival in the face of warming oceans, says IUCN's latest report.
"We already know that climate change is destroying coral reefs through warming waters that cause coral bleaching and through acidifying oceans that hinders coral skeleton growth. We also know that if we want to save these beautiful living entities we must do something about it immediately," says Gabriel Grimsditch, IUCN Corals Expert.
