Abstract High-resolution seismoacoustic and multibeam data revealed a large field of sediment waves covering the Santa Catarina Plateau on the Brazilian Southern Margin. Within the field several zones were determined: a zone of large sediment waves (up to 70 m in height), a zone of smaller sediment waves (15–30 m in height) and a zone of buried sediment waves. The correlation of the seismoacoustic and multibeam data with the results of numerical modeling of bottom current velocities showed a strong influence of bottom currents on the formation of sediment waves. The process of wave burial in the northern part of the field can be caused by the interplay between gravity flows from the continental slope and bottom currents.

圣卡塔琳娜高原（南大西洋西部）的沉积波

摘要 高分辨率地震声和多波束数据揭示了覆盖巴西南缘圣卡塔琳娜高原的大范围沉积波。在现场确定了几个区域：一个大沉积波区（高达 70 m 的高度），一个较小的沉积波区（15-30 m 高）和一个埋藏的沉积波区。地震声和多波束数据与底流速度数值模拟结果的相关性表明底流对沉积波的形成有很大的影响。油田北部的波浪埋藏过程可能是由大陆坡重力流与底流相互作用引起的。
