Wesmar’s Sonar Series EV850

WESMAR is introducing the EV850 series, a new, all digital navigation and security sonar. This searchlight sonar provides detailed information about the waters around and beneath boats while at anchor or cruising. Thanks to active stabilization, the new sonar series provides target tracking even in rough water. Additionally, the sonar screen never leaves the monitor when making adjustments, essential to avoiding hazards or tracking divers. The sonar has the ability to detect and follow divers many hundreds of feet away, providing early warning and time for response.

The U.S. Coast Guard is planning to widely use sonar to support its maritime security and marine environmental protection missions. The agency currently has limited capability to detect objects below the water’s surface and relies on others (such as the U.S. Navy or the commercial sector) when such detection is needed. Sonar is an acronym for Sound Navigation and Ranging. The principle is similar to radar, used in the atmosphere. While radar uses radio waves, sonar relies on sound waves, which propagate much better than radio waves do in water.

Groups Sue to Stop Navy From Using Sonar

According to the Houston Chronicle, environmental groups sued the federal government to prevent the Navy from using active sonar during drills off Hawaii next month, saying the sound could harm whales and other marine mammals. The Natural Resources Defense Council asked a federal court in Los Angeles to issue a temporary restraining order unless the Navy takes "effective measures" to protect marine life when it uses high-intensity, mid-frequency active sonar to hunt submarines in the drills. Navy lawyers haven't seen the lawsuit and couldn't comment. The National Oceanic and Atmospheric Administration declined to comment, but said the agency was confident the Navy would protect dolphins and whales.

China Buys Side Scan Sonar

China’s state owned Guangdong Construction Engineering Group (GCEG) has purchased JW Fishers side scan sonar system. The sonar is being used to the map the bottom of various waterways before and after construction projects. It is providing engineers with information on the make up of the bottom (mud, sand, rock, etc.), as well as helping to locate and identify debris or any obstructions. Using Fishers side scan sonar and Sonar View software, GCEG engineers are able to produce detailed maps of the bottoms of rivers, lakes, and the ocean. The sonar images can be displayed on a standard laptop computer or Fishers Splashproof PC with ultrabright LCD display.

In November 2008 the Ministry of Defence (MoD) announced that HMS Sutherland had left Rosyth dockland for the trials after a multi-million pound refit that included major upgrades to its sonar…

Navy Encouraged by Appeals Court Ruling

Navy officials said they are optimistic that a three-judge panel of the U.S. 9th Circuit Court of Appeals Nov. 13 ordered a lower court to rewrite restrictions on the Navy's use of sonar in certain Southern California exercises. That ruling was part of a lawsuit challenging the Navy's ability to train Sailors before they deploy to potential hotspots. The Navy had asked the appeals court to overturn a preliminary injunction that was granted by a U.S. district judge on Aug. 6, 2007, that bars the Navy from using active sonar in certain multi-ship exercises off Southern California through January 2009. That injunction was granted in a lawsuit filed by the Natural Resources Defense Council and other environmental and animal protection groups.

Thales Secures Contract from UK Navy

Thales has signed a five-year contract with the U.K.’s Ministry of Defence to provide support for the Sonar 2050 antisubmarine sensor used on the Royal Navy’s Type 23 frigate fleet. Sonar 2050 is a medium-range bow sonar currently fitted to 13 Type 23 frigates and is the Royal Navy’s primary hull-mounted antisubmarine warfare sensor.

U.S. Navy Asserts State Secrets in Sonar Case

The U.S. Navy on Tuesday said it had asserted the "state secrets" privilege in a lawsuit by environmental groups, a move to keep the military from being forced to disclose classified information about the use of sonar believed to injure whales and other animals. The state secrets privilege, if upheld, renders information unavailable for litigation. It can be challenged, although the federal government often succeeds in asserting the protection. The Navy action is the latest in a string of Pentagon moves to derail the group's lawsuit. The Natural Resources Defense Council and other environmental groups say sonar used in routine training and testing violates environmental laws. They also argue the Navy's sonar injures and kills marine mammals, including whales and dolphins.

Coastal Commission Sues Navy Over Sonar Use

The state Coastal Commission and a national environmental group sued the Navy over its refusal to take certain precautions to protect marine mammals during military training exercises off the coast of San Diego, reported the Union Tribune. While the commission's legal action is a rarity, the Natural Resources Defense Council already had sued the Navy four times over its use of high-intensity sonar. In separate lawsuits filed Thursday, the commission and the council want the Navy to adopt more stringent safeguards for whales, dolphins and other marine mammals, which can be injured or killed by sonar. The sound waves, which travel hundreds of miles across water, are used to track submarines and surface ships. Navy officials could not be reached for comment on the lawsuits.
