Seismic Water Bottom Anomalies - Gulf of Mexico

Seismic Water Bottom Anomalies - Gulf of Mexico This National Geospatial Data Asset (NGDA) dataset, shared as a Bureau of Ocean Energy Management (BOEM) feature layer, depicts seafloor seismic features related to the geological framework of the northern Gulf of Mexico (GOM). Per BOEM, “The purpose of this mapping program is to understand the distribution of natural hydrocarbon seeps and related benthic fauna (chemosynthetic and coral communities) in the GOM, and to characterize other seafloor features related to the geological framework of the seafloor. These areas show anomalously high or low acoustic amplitude response relative to typical background, with most areas having overlapping seismic coverage by two or more surveys. These results cover over 230,000 square kilometers of seismic data interpretation.” Seep Anomaly Positives & Plumes EK60 Point features Data currency: Current Federal Service (BOEM Seismic Water Bottom Anomalies) NGDAID: 56 (BOEM Seismic Water Bottom Anomalies - Gulf of Mexico - Gulf of Mexico NAD27) For more information: Seismic Water Bottom Anomalies Map Gallery For feedback please contact: [e-mail] NGDA Theme Community This data set is part of the NGDA Geology Theme Community. Per the Federal Geospatial Data Committee (FGDC), Geology is defined as “Geographically-referenced data pertaining to the origin, history, composition, structure, features, and processes of the solid Earth, both onshore and offshore. Includes geologic, geophysical, and geochemical maps, stratigraphy, paleontology, geochronology, mineral and energy resources, and natural hazards such as earthquakes, volcanic eruptions, coastal erosion, and landslides. Does not include soils.” For other NGDA Content: Esri Federal Datasets墨西哥湾海底地震异常（Seismic Water Bottom Anomalies - Gulf of Mexico） 本数据集属于国家地理空间数据资产（National Geospatial Data Asset，NGDA），以美国海洋能源管理局（Bureau of Ocean Energy Management，BOEM）要素图层形式共享，描绘了墨西哥湾北部地质框架相关的海底地震特征。 据BOEM官方说明：“本制图项目旨在探明墨西哥湾天然烃类渗漏及相关底栖生物群落（化能合成生物与珊瑚群落）的分布，并表征与海底地质框架相关的其他海底特征。此类区域的声学振幅响应相较于典型背景值存在异常偏高或偏低的情况，多数区域已获得两次及以上勘测的重叠地震覆盖。本次研究成果覆盖了超过23万平方千米的地震解译范围。” 渗漏异常阳性点与羽流EK60点要素 数据时效性：当前联邦服务数据集（BOEM海底地震异常） NGDA编号：56（墨西哥湾海底地震异常——墨西哥湾NAD27坐标系） 更多信息请参阅：海底地震异常地图图库 反馈联系方式：[e-mail] NGDA地质主题社区 本数据集隶属于NGDA地质主题社区。根据美国联邦地理数据委员会（Federal Geospatial Data Committee，FGDC）的官方定义，地质学是“涉及固态地球（包括陆上与近海区域）的起源、演化历史、组成、结构、特征与过程的地理参考数据，涵盖地质、地球物理、地球化学图件、地层学、古生物学、地质年代学、矿产与能源资源，以及地震、火山喷发、海岸侵蚀与滑坡等自然灾害相关数据，不包含土壤类数据”。 其他NGDA相关内容请参阅：Esri联邦数据集
