    AbstractThis survey was carried out by IMAR using the RV Conamara vessel in November 2007. The purpose of the work was to provide hydrographic data. The primary system for gathering the bathymetric data was the Kongsberg Simrad EM3002D multibeam echosounder, mounted on the bow underwater plate and operating at a frequency of 297khz (Sonar Head1) and 303 kHz (Sonar Head2). Primary positioning was the C-Nav DGPS system, using differential corrections (RTG-format), derived by C&C Technologies company. C-Nav provides a worldwide GcGPS (Globally corrected GPS) system with an accuracy of 0.18m (95% confidence) horizontally and 0.35m (95%) vertically. Data Accuracy of IHO Order 1. All of this data & reports ( IMAR_07_Galway_Bay_Leg_Report.pdf) can be downloaded free of charge in a variety of formats from https://jetstream.gsi.ie/iwdds/20071494)
