Processed EM304 Acoustic Backscatter and Swath Bathymetry data from R/V Gaia Blu cruise Jamme Gaia22 (2022)

This data set was acquired with a Kongsberg Maritime EM304 multibeam sonar system during R/V Gaia Blu cruise Jamme Gaia22 conducted in 2022. In September-October, 2022, the new CNR Research Vessel Gaia Blu explored the seafloor of the Naples and Pozzuoli Gulfs, and the Amalfi coastal area (Tyrrhenian Sea, Italy) from 50m to more than 1300m water depth, acquiring about 5000 km2 of multibeam echo-sounder data. The purpose of the cruise was to test the new multibeam systems installed on R/V Gaia Blu and to use the high-resolution digital bathymetric models generated from the acquired data to improve knowledge of the seascape and seabed morphology of the Gulf of Naples. These data files are in MB-System-compatible format and include Acoustic Backscatter and Swath Bathymetry data that was processed after acquisition. This data was processed by Istituto di Scienze Marine and was included in the Global Multi-Resolution Topography (GMRT) Synthesis (version 4.2.1).

本数据集由康士伯海事（Kongsberg Maritime）EM304多波束声呐系统采集，数据源自2022年执行的“盖亚蓝号”（R/V Gaia Blu）科考航次Jamme Gaia22。2022年9至10月，全新的CNR“盖亚蓝号”科考船对意大利第勒尼安海的那不勒斯湾、波佐利湾及阿玛菲海岸区域开展海底探测作业，作业水深覆盖50米至1300米以上，累计采集约5000平方千米的多波束测深数据。本次航次的核心目标为验证安装于“盖亚蓝号”科考船上的新型多波束系统，并利用采集数据生成的高分辨率数字水深模型，深化对那不勒斯湾海域景观与海底地貌的认知。本数据集文件采用MB-System兼容格式，包含采集后经过处理的声学背散射（Acoustic Backscatter）数据与条带测深（Swath Bathymetry）数据。本数据集由意大利海洋科学研究所（Istituto di Scienze Marine）完成处理，并已纳入全球多分辨率地形合成（Global Multi-Resolution Topography，GMRT）合成库（版本4.2.1）。
