Mr. Ransome graduated from Southampton University in the UK in 1972 with a degree in Geology, and then from Durham University with a Masters degree in Geophysics in 1973 before joining the British Geological Survey. There he was the geologist in charge of producing the Solway Firth Quad Sheet which included reviewing and acquiring both sediment and core samples as well as bathymetry, sidescan sonar, and sub-bottom profiling data. Mr. Ransome then pursued a PhD in Crustal Seismology for two years at Birmingham University in the UK before joining D’Appolonia Consulting Engineers in Brussels, Belgium. Here he worked on nuclear power siting studies in Turkey, Italy, and Spain as well as seismic risk analysis on offshore oil production platforms in the Adriatic Sea. After a brief period with Gardline Surveys in the North Sea working on sales and marketing for engineering geophysical investigations, Mr. Ransome was recruited to join the initial management team from Wimpol (UK) to start a new division of that offshore survey company in Houston in late 1982. He became President of Wimpol Inc. in 1984 before leaving to start another offshore survey company, Aquanav, in 1985. Chris Ransome & Associates, Inc. was started in late 1986, to provide high tech hydrographic surveying services to the civil engineering industry.
Mike LahrV.P. Marine
Mr. Lahr graduated in 1976 with a degree in Forest Engineering from the State University of New York before starting work for a specialist survey company, Aero Services, in Houston in April of 1977. There he was a Party Chief working on establishing vertical and horizontal control both in the USA and overseas in Libya using both traditional land survey equipment as well as the new U.S. Navy “Transit” satellite receivers. In 1981, Mr. Lahr joined International Technology Inc. (ITECH) as a field supervisor involved with numerous types of onshore and offshore geodetic positioning projects through the U.S. and the world. He was responsible for the operation of various types of radio positioning systems, including Motorola "Miniranger", Del Norte “Trisponder”, Loran, and Sercel “Syledis”. He also set horizontal control with Magnavox Transit and Trimble GPS receivers. During this period, Mike became experienced with the Litton Dash II Inertial Survey System, with a wide range of conventional land survey equipment. In March of 1987, Mike became the first employee of CRA working as a Project Manager for survey services for the largest hopper dredger in the USA, the “Stuyvesant”. Since then, he has been in charge of a variety of surveys for the dredging and civil engineering industries, including offshore rig positioning, hydrographic and geophysical surveys for underwater pipelines, and transition zone seismic surveys, and A/E survey services in support of U.S. Army Corps of Engineers' indefinite delivery contracts for the New York and Detroit districts. Mr. Lahr is now in charge of all CRA’s marine field activities.
