构建了波罗的海普克湾高分辨率光学与声学遥感数据集，助力海洋生态与文化遗产研究。
High-resolution optical and acoustic remote sensing datasets of the Puck Lagoon, Southern Baltic
- 融合机载激光测深、多波束声呐等多源数据生成高精度数字高程模型
- 涵盖海底地貌、沉积物特性及未发现的水下遗迹，揭示关键生态与考古信息
- 为海洋可持续管理提供科学基础，适合生态、考古与地理研究者使用
波兰北部波罗的海普克湾是浅水海洋盆地，拥有重要的底栖生境和文化遗产，包括受保护的鳗草草甸、波罗的海主要中世纪港口、沉船墓地及其他未知水下遗迹。此前该区域缺乏综合的高分辨率遥感数据。本文首次基于机载海道激光雷达、多波束测深仪、航空摄影测量和卫星影像融合生成数字高程模型（DEMs）。数据集还包含多波束回波强度和激光雷达强度，可用于分析海底特征与属性。这些高分辨率数据对评估海底形态、底栖生境、文化遗产及水下景观具有重要价值。鉴于普克湾在水文、生态、地质与考古上的重要意义，本项目获取的高分辨率地形数据可为该区域的可持续管理与科学决策提供坚实基础。
原文摘要 · Abstract (English)
The very shallow marine basin of Puck Lagoon in the southern Baltic Sea, on the Northern coast of Poland, hosts valuable benthic habitats and cultural heritage sites. These include, among others, protected Zostera marina meadows, one of the Baltic's major medieval harbours, a ship graveyard, and likely other submerged features that are yet to be discovered. Prior to this project, no comprehensive high-resolution remote sensing data were available for this area. This article describes the first Digital Elevation Models (DEMs) derived from a combination of airborne bathymetric LiDAR, multibeam echosounder, airborne photogrammetry and satellite imagery. These datasets also include multibeam echosounder backscatter and LiDAR intensity, allowing determination of the character and properties of the seafloor. Combined, these datasets are a vital resource for assessing and understanding seafloor morphology, benthic habitats, cultural heritage, and submerged landscapes. Given the significance of Puck Lagoon's hydrographical, ecological, geological, and archaeological environs, the high-resolution bathymetry, acquired by our project, can provide the foundation for sustainable management and informed decision-making for this area of interest.
