CV16015 INFOMAR (Seabed Mapping) Celtic Sea Survey

The INtegrated Mapping FOr the Sustainable Development of Ireland’s MArine Resource (INFOMAR) programme is a joint venture between the Geological Survey of Ireland (GSI) and the Marine Institute (MI). The programme is a successor to the Irish National Seabed Survey (INSS) and concentrates on creating a range of integrated mapping products of the physical, chemical and biological features of the seabed in the near-shore area. This 21 day survey took place on board the RV Celtic Voyager in 2016 from 21st March to 04th April in the Celtic Sea, off the Co. Cork Coast. Surveys undertaken include: Multibeam Echo Sounder (MBES) hydrographic survey to International Hydrographic Organisation (IHO) Order 1a standard. Bathymetry survey: to produce bathymetry shaded relief and backscatter mosaic products which provide depth, seabed features and seabed hardness information. Sub Bottom Profiler (SBP) survey: to acquire data of the shallow (up to 30 metres) sub seabed to determine the existence of buried objects and ascertain the sub-seabed character. A magnetometer was used to acquire data on sub seabed geology to provide information on manmade seafloor debris. Shipwrecks were also surveyed. An area of 515km2 was covered during this survey. Mapping Ireland's seabed resource programme.爱尔兰海洋资源可持续发展综合制图计划（Integrated Mapping For the Sustainable Development of Ireland’s Marine Resource，缩写INFOMAR）是爱尔兰地质调查局（Geological Survey of Ireland，缩写GSI）与爱尔兰海洋研究所（Marine Institute，缩写MI）联合实施的项目。该项目作为爱尔兰国家海底调查（Irish National Seabed Survey，缩写INSS）的后续计划，专注于近岸海域海底物理、化学及生物特征的系列综合制图产品研发。本次为期21天的科考作业于2016年3月21日至4月4日在科克郡沿岸的凯尔特海海域开展，搭载平台为“凯尔特航海者号”（RV Celtic Voyager）科考船。本次作业实施的勘测项目包括：多波束回声测深仪（Multibeam Echo Sounder，缩写MBES）水文勘测，符合国际海道测量组织（International Hydrographic Organisation，缩写IHO）1a级标准；水深测量作业：生成水深晕渲图与反向散射镶嵌产品，以提供水深、海底地形特征及海底硬度相关信息；浅地层剖面仪（Sub Bottom Profiler，缩写SBP）勘测：采集浅部（最大深度30米）海底地层数据，用于判定埋藏物的存在情况并明确海底浅层地层特征；采用磁力仪采集海底地层地质数据，以获取人工海底残骸相关信息；同时对沉船遗址开展了勘测。本次勘测覆盖海域面积达515平方千米，本项目即爱尔兰海底资源制图计划。
