Hydro International – 

StarFish Seabed Imaging Systems, the shallow water, side scan sonar system from Tritech (UK), has been successful in a SAR operation for body recovery.

Where other sonar failed to locate the missing person, StarFish 990F’s high resolution imagery was able to lead the rescuers to recover the body of a sailor who had drowned and had been missing for over 10 years.

Derek Flanagan, Divisional Controller, Irish Coast Guard comments that searching for a submerged victim can be long, frustrating and dangerous for their boat teams, Police and Navy divers.

Using the StarFish side scan sonar will enable the Irish Coast Guard to search large areas relatively quickly and safely, adding an extra dimension to our search team’s capability.

StarFish demonstrations at the Dublin Water Rescue Conference in October 2011 generated strong interest from the SAR community.

The meeting brought together key SAR professionals as well as underwater technology companies and included Tritech, SeaBotix and the Irish Coast Guard.

Cebu Daily News – 

This was suggested by Gary Cases, an official of the Philippine Commission on Sports Scuba Diving (PCSSD), during Friday’s public hearing on a proposed Provincial Ordinance regulating scuba diving in Cebu.

Cases said mishandled diving gear would pose more danger to the person using it.

Cases, who is also a dive shop operator in Malapascua Island, cited an incident in Bohol where a dive shop worker lost his hand when an oxygen tank exploded.

“Tanks are like bombs. Mishandling them could endanger the lives of people,” he told the Provincial Board (PB).

Also present in the public hearing was PB member Sun Shimura, Cordova Mayor Adelino Sitoy, , dive shop operators and tourism students of the University of San Carlos (USC).

Cases also suggested that foreigners should be covered in the regulation of individuals under the proposed ordinance.

He said an ordinance would be a big help to to his organization since the PCSSD has no police powers over individual divers.

PBS Newshour – 

Will your city or county be flooded by 2020? By 2050? Now there’s a map for that.

As many as 3.7 million U.S. residents in 2,150 coastal areas could be battered by damaging floods caused by global warming-induced storm surges, according to a new report published Wednesday in the journal Environment Research Letters.

Sea levels could rise as much as 19 inches by 2050, according to what the report calls “mid-range projections.”

The team used data from the U.S. Geological Survey to map all areas along the continental U.S. coastline containing homes that lie within one to 10 feet from the water level at high tide.

Previous estimates only looked at an area’s elevation above sea level, not at the area’s elevation relative to high tide, which underestimated the impact, said Benjamin Strauss, lead author and director of Climate Central’s Program on Sea Level Rise.

Climate Central is the nonprofit organization behind the report.

The map shows the areas at risk of flooding with every foot of sea level rise. Move the slider bar at the left to increase the sea level rise, and the areas on the map that are subject to being flooded or entirely underwater grow.

As the bar moves, you can watch the population, number of homes and acres of land in danger swell in size.

The map also shows the likelihood for each decade that sea level rise plus storm surge plus tide will reach a certain threshold.
