The INFOMAR Project in the Geological Survey of Ireland (GSI), a division of the Department of Communications, Energy and Natural Resources, seeks proposals for Hydrographic Mapping Services to carry out survey ship, marine deep water mapping on behalf of the INFOMAR Project. This is the national marine mapping programme, which is a continuation of the Irish National Seabed Survey (INSS) and is being undertaken as a joint venture between GSI and the Marine Institute (MI) (www.infomar.ie).
