News A huge amount of sub-bottom proÞ ler data has recently been collected by MMT. MMT (Sweden) have successfully completed a survey which includes collection of parametric sub-bottom proÞ le (SBP) data with a Kongsberg TOPAS PM 40 system. The system was hullmounted on MMT«s survey vessel Triad. The survey covered an area of 6000km2 in the Baltic Sea with an extensive amount of data. The SBP data was collected during a hydrographic survey for the Swedish Maritime Administration (SMA) where high resolution bathy- metric data will be used to update sea charts. Additionally will the SBP data from TOPAS PM 40 give the client a detailed picture of the sediment layers of the surveyed area. MMT«s Technical & Operation Director Mr. Martin Wikmar said, ÒThis particular project has given us extensive experience in high graded parametric sub-bottom proÞ ling. By provid- ing our client the best systems and methods on the market we continuously prove that we are a forefront survey company.Ó MMT Completes 6,000 sq. km Survey using Kongsberg TOPAS PM40 Kongsberg TOPAS 40 data example from the MMT survey, showing outcropping bedrock cov- ered in parts by layered clay.

Saab Seaeye Opens Largest Test Tank The largest indoor test facility ever before dedi- cated to the development of unmanned underwa- ter vehicles has been opened by Saab Seaeye, the company claims. Located in Link?ping, Sweden, the test tank will allow new underwater systems technology to be tested in a controlled environment rather than in a lake or at sea. The tank is 6m deep, 10m in diameter and holds approximately 470 cu. m. of water. ÒSaabÕs underwater operations are currently in a very expansive phase,Ó explains G?r- gen Johansson, Senior Vice President and Head of SaabÕs Business Area Dynamics, Òand by investing in ultra-modern facilities such as this, we increase our ability to offer underwater systems and solu- tions for both military and civil applications.Ó The company sees the new facility bringing signiÞ cant savings in time and costs, while offering a unique opportunty to develop and trial underwater systems that will future strenghen its product portfolio.May 201310 MTRMTR #4 (1-17).indd 10MTR #4 (1-17).indd 105/6/2013 9:54:21 AM5/6/2013 9:54:21 AM
