Lithofacies distribution in the western Bay of Plenty, New Zealand@en

Sediment dynamics on a storm-dominated shelf (western Bay of Plenty, New Zealand) were mapped and analyzed using the newly developed multi-sensor benthic profiler MARUM NERIDIS III. An area of 60 km × 7 km between 2 and 35 m water depth was surveyed with this bottom-towed sled equipped with a high-resolution camera for continuous close-up seafloor photography and a CTD with connected turbidity sensor. Here we introduce our approach of using this multi-parameter dataset combined with sidescan sonography and sedimentological analyses to create detailed lithofacies and bedform distribution maps and to derive regional sediment transport patterns. […]本研究针对新西兰普伦蒂湾西部风暴主导陆架的沉积物动力学开展了填绘与分析工作，所用仪器为最新研发的多传感器海底剖面仪MARUM NERIDIS III。研究团队使用搭载有用于连续近距海底摄影的高分辨率相机，以及连接浊度传感器的温盐深仪（CTD）的底拖式滑橇，对水深2~35 m范围内的60 km×7 km海域实施了调查。本文介绍了本研究的分析方法：将该多参数数据集与侧扫声呐成像、沉积学分析相结合，以此生成高精度岩相及沉积底形分布填图，并推导得到区域沉积物输运格局。[…]
