POS336 raw data of SB1050 multibeam echosounder (bathymetry & beam time series)@en

Between 28.04.2006 and 17.05.2006, bathymetric data was acquired in the Eastern Mediterranean Sea during the R/V POSEIDON cruise P336. The expedition was dedicated to studying slope instability and related geohazardous processes at the northern Cretan Margin and the slopes of the Aegean volcanic islands. The cruise aimed at an understanding of parameters controlling sediment physics, and ultimately geohazards such as landslides and other mass wasting events. Bathymetric mapping with the multibeam echosounder (MBES) ELAC SEABEAM 1050 was used to survey approximately 2450 km² of the study area and identify landslide and mass wasting deposits. Based on hydroacoustic and seismic data, these deposits were characterised by in-situ measurements, such as Cone Penetrating Testing and sub-surface heat flow measurements, and sampling, such as gravity coring and laboratory studies on board. […]2006年4月28日至2006年5月17日，科研团队在东地中海执行"海神号"（R/V POSEIDON）科考航次P336，期间采集了水深测量数据。本航次旨在研究克里特北部陆缘与爱琴海火山岛斜坡的斜坡失稳及相关地质灾害过程，核心目标为厘清控制沉积物物理特性的参数，最终揭示滑坡及其他块体搬运（mass wasting）事件等地质灾害的形成机制。研究团队使用多波束测深声呐（multibeam echosounder, MBES）ELAC SEABEAM 1050开展水深测绘作业，覆盖研究区约2450平方千米，以此识别滑坡与块体搬运沉积体。基于水声与地震数据，研究团队通过原位测试（如静力触探试验（Cone Penetrating Testing）与地下热流测量）以及采样工作（如重力取芯与船载实验室分析）对上述沉积体进行了特征表征。[…]
