INFOMAR (Seabed Survey) Gravity data around Ireland

Gravity is the measure of the force of attraction at any point on the Earths surface. This force will vary depending on the rock type present. Gravity data is used for interpreting sub-seabed geology often in the context of the hydrocarbon exploration and mining industry, as well as to define the boundaries of the sedimentary basins. Gravity data has been collected along survey lines. This dataset provides details of the gravity data mapped under both the Irish National Seabed Survey (INSS) and INtegrated Mapping FOr the Sustainable Development of Irelands MArine Resource (INFOMAR) programmes. Gravity data from INFOMAR surveys have been collected in foreshore and offshore waters around Ireland. Gravity data has been collected between 2000 and 2007. Gravity data has been collected using gravity corers. Gravity data supports enhanced knowledge and understanding of the geologic nature of the sub seafloor. The INtegrated Mapping FOr the Sustainable Development of Irelands MArine Resource (INFOMAR) programme is a joint venture between the Geological Survey of Ireland (GSI) and the Marine Institute (MI). The programme is the successor to the Irish National Seabed Survey (INSS) and concentrates on creating integrated mapping products related to the seabed.

重力为地球表面任意一点的吸引力度量。此力的大小取决于存在的岩石类型。重力数据在解释海底地质结构时得到广泛应用，尤其是在烃类勘探和采矿行业中，以及用于界定沉积盆地的边界。重力数据沿测线进行收集。本数据集提供了在爱尔兰国家海底调查（INSS）和爱尔兰海洋资源可持续发展综合制图计划（INFOMAR）两项计划下测绘的重力数据的详细信息。INFOMAR调查的重力数据在爱尔兰沿海及海上区域收集。重力数据的收集时间介于2000年至2007年之间。重力数据的收集采用重力岩芯法。重力数据有助于深化对海底地质特性的认知与理解。爱尔兰海洋资源可持续发展综合制图计划（INFOMAR）是爱尔兰地质调查局（GSI）和海洋研究所（MI）的联合项目，该计划是爱尔兰国家海底调查（INSS）的继承者，专注于制作与海底相关的综合制图产品。重力数据已覆盖了爱尔兰调查区域内感兴趣的地区的完整重力数据。
