New Product Release: 4900 Series Side Scan / Sub bottom System

January 4, 2008 - Ross Laboratories, Inc. has introduced a new integrated Side Scan Sonar / Sub Bottom Profiler survey system. The portable modular design allows the user to configure a system that will best suit their requirements. Housed in two rugged Pelican™ cases, the system is ideal for surveyors traveling to remote areas using small local vessels.

Three versions are available. Each one can be configured for both Side Scan and Sub Bottom or one system only. The second system can easily be added at a later date.

Model 4901 - A complete system housed in two splash proof portable cases. The main display controller has a 12 inch 1000nit LCD display for use in open boats and bright sun light operations. The second case houses the transceiver assembly and is connected to the display unit via a 20 foot interconnect cable.

Model 4910 - An add on option for the popular 960 Surveyor. Now Side Scan / Sub Bottom capability can be added to the all in one concept developed by Ross Laboratories in the 1990s that puts a complete survey system in one portable case. The 960 features a DGPS, two frequency sounder, and data collection computer in a portable case. With the addition of the 4910 option and second transceiver case, Side Scan and Sub Bottom profiling can be added to this highly portable system.

Model 4920 - Analog sonar controller. Owners of earlier analog sonar systems such as the popular ISIS™ system can now replace their aging towfish and receiver systems with the 4920 analog controller. A small control box, transceiver unit, and towfish make up the system.

Ross Laboratories Receives Export Achievement Certificate

Ross Laboratories Inc. of Seattle Wa. has been awarded an “Export Achievement Certificate” by the U.S. Commercial Service a division of the Dept. of Commerce. Ross Laboratories, a long time supplier of precision hydrographic survey equipment to U.S. government agencies as well as many private survey firms, was recognized for their effort in developing new markets with sales that included Europe, The Middle East, and Asia. The award was given to six Seattle area companies in recognition of their efforts to promote their products internationally in a variety of markets. The presentation was at a legislative reception and dinner held at Salty’s Restaurant in Seattle the evening of May 30th 2006, to celebrate and recognize Washington State Manufacturers as part of "Manufacturers Appreciation Week". Representative Jim McDermott presented the award to Jim Ross, President of Ross Laboratories. During his brief acceptance remarks, Jim thanked the Seattle office of the U.S. Commercial Service, for their help over the last three years. “ Without their support and guidance it would be very difficult for a small company such as ours to understand and comply with the complex regulations and requirements involved with international marketing”.

St. Louis Surveyors Helping Out In New Orleans
By Joe Burnett, Geodesist St. Louis District, COE
The New Orleans District asked the St.Louis District to bring their SeaArk 2272 River Runner with its newly outfitted Ross 875-5, five-channel multi-transducer system, to perform hydrographic surveys of several of the outfall canals within New Orleans. The main reasons for requesting this vessel was due to its shallow drafting, shallow and high-resolution recording, and low clearance abilities. These outfall canals are being surveyed to determine their channel bottom configurations. Amultitude of analyses will be conducted with the data collected. Among these analyses, will be seepage and stability concerns.
Also, new volume capacities for each outfall canal will be calculated. The team members from the St. Louis
District performing these surveys are myself, (Joe Burnett) and Randy Trout. Assisting us from the New Orleans District is Shawn Kempshall.
The Ross 875-5 system consists of five transducers, placed in a line, on two collapsible booms. The Ross 875 system has been specifically calibrated and tuned to collect depths as shallow as 1.0 feet below the face of the transducer. The total swath width is 26 feet, with each transducer evenly spaced at 6.5 feet apart. However, the spacing is user-defined and can be placed at any distance apart. The GPS antenna
is placed directly over the middle transducer and offsets to the other four transducers are entered into HYPACK’s data collection software. A Honeywell HMR 3000 sensor is placed on the boom just below the GPS antenna and compensates for heading, pitch, and roll. The range of depths encountered during these surveys were from 18 inches to 18 feet, which made this system the ideal choice for this project. The St. Louis District’s main reason for acquiring this system was for use in shallow, back channel areas along the Mississippi River. Bathymetry collected with this system will aid fisheries biologists within the Corps of
Engineers, Departments of Conservation, and Fish and Wildlife Services. This shallow water data will be used to study existing and potential habitat areas that were previously unmap-able.
