Gerard Costello has been a Hydrographic Surveyor with the Canadian Hydrographic Service since 1979. He graduated from the University of New Brunswick with a degree in Survey Engineering and has worked in both the Atlantic and Quebec Regions of CHS, where he developed his expertise in hydrographic surveying. During the past few years, Mr. Costello has been managing the CHS Coastal and Ocean Mapping Program, where he introduced such new technologies as the multi-beam survey systems and associated computer-aided data processing. He has recently been awarded the DFO Deputy Minister's Commendation Award, in recognition of his achievements with CHS.
