More Public Safety Dive Teams Employ Side Scan Sonar

More public safety dive teams are adding sonar to assist in their underwater search and recovery operations. Side scan is the ideal tool for these operations because it produces detailed images of the underwater environment regardless of water clarity. In addition, the sonar is able to search large areas quickly, scanning several hundred feet of ocean, lake, or river bottom with each pass of the boat. The sonar does this by transmitting an acoustic beam from a towfish which sweeps the bottom and reflects off any objects lying there.

Vessels: Year Two A Tale of Tugs of Two Cities

It's been a year since MarineNews linked the dual tugmeets of the first week of September, one in New York City, the other upstate, at Waterford. Coupled, they make an interesting study, for their differences as much as their similarities. The tugs of New York City come in all sizes, but are typically large. Just as New York is a city of (many) skyscrapers, so it's a city of (many) monster tugboats, as harbor craft go. Waterford, a few miles north of Albany, is the gateway to the Erie Canal - is actually on the canal. While New York State's canals have renewed potential for commercial service, they're known most widely as recreational attractions for people who drive (many) large and pricey boats.

Mobile ISDN Service Unveiled

Inmarsat presented its new Mobile ISDN service at IBC, the International Broadcasting Conference in Amsterdam from September 10-14. This new service, developed with valuable input from the New Media Committee of the World Broadcasting Union, will support a range of newsgathering tools at a communications rate of 64 Kpbs, while using portable satellite terminals the size of a notebook computer. Weighing 9 lbs, these terminals are a quarter of the size of the equipment that is used to relay video via Inmarsat's global satellite network.
