冲绳海槽中部热液区地形复杂度研究
Seabed terrain complexity study of the hydrothermal fields in the mid-Okinawa trough
摘要
Abstract
The study of terrain complexity is of great significance to systematically study the distribution characteristics of global submarine hydrothermal zones.In this paper,a comprehensive analysis model of terrain complexity is established based on the high-resolution seabed topographic data collected by the research ship"Science"of the Institute of Oceanology,Chinese Academy of Sciences in the hydrothermal zone of the central Okinawa Trough.Moreover,the topographic complexity of hydrothermal area in the middle Okinawa trough was analyzed by means of window sequence analysis and mean change point analysis.The results showed that the average topographic complexity index in the study area was 1.74,and the topographic complexity index in the hydrothermal active area was between 1.4 and 3.2,indicating that the terrain in the hydrothermal active area was relatively complex.We provide a new idea to calculate the topographic complexity of global submarine hydrothermal zone and find the location of hydrothermal active zone.关键词
