摘要

本文讨论了保加利亚黑海南部海岸——从Emine角到Maslen角的广阔布尔加斯湾的复合海底数字地形模型的创建,该模型是对来自bas海洋研究所的单波束回声测深仪和多波束声纳系统的数据、测深激光雷达数据和来自海洋航海图的数字化水线数据进行处理和组装的结果。单波束测深和多波束声纳系统的数据是在多个国际和国家项目的实施过程中获得的。没有数据的区域,通过在周围地形的基础上人工绘制等深线,并以55米的步长圆插值完成。通过综合所有数据,创建了一个分辨率为1/128弧分或单元尺寸为14米的海底地形综合三维数字地形模型。数字地形模型可以详细了解海底形态,并成功地用于编制高精度的航海图。这项工作是在支持保加利亚科学院青年科学家和博士生方案下实施一个项目的结果。

Digital terrain model of the seafloor of south bulgarian black sea coast
Summary The paper discuss the creation of a composite seafloor digital terrain model of the south Bulgarian Black Sea coast - broad Burgas Bay from Cape Emine to Cape Maslen nos. It is a result of processing and assembling data from single beam echosounder and multibeam sonar systems derived from the Institute of Oceanology-BAS, bathymetric LiDAR data and data from digitizing water lines from marine navigational charts. Data from single beam echosounder and multibeam sonar systems were acquired during the implementation of various national and international projects of IO-BAS. Areas where no data are available were completed by manually drown isobaths built on the grounds of the surrounding terrain and circular interpolation with step of 55 meters. By combining all the data a comprehensive 3D digital terrain model of the topography of the seafloor with resolution of 1/128 arc minute or cell size of 14 meters was created. The digital terrain model allows detailed understanding of the seafloor morphology and successfully can be used in the compilation of highly accurate, navigational charts. The work is a result of the implementation of a project under the Program for supporting young scientists and PhD students at the Bulgarian Academy of Sciences.
