Abstract

Geological, hydrological, hydrochemical, and biological research has been carried out in the eastern tropical Atlantic. Based on the multibeam echo-sounding and seismic profiling north of the Kane Gap (Sierra Leone Rise), an extensive sedimentary body (contourite fan) has been identified. Data of hydrophysical sounding allows assuming the existence of an overflow of the Antarctic Bottom Water (AABW) through the Kane Gap and its northward penetration. In the sediment cores (Middle Pleistocene to Holocene age), an influence of the AABW is reflected in the alternation of the high and medium carbonate dissolution rates.

热带大西洋东部研究船Akademik Nikolaj Strakhov第44次航行期间的复杂海洋学研究

摘要

在东部热带大西洋已经进行了地质，水文，水化学和生物研究。根据凯恩峡（塞拉利昂崛起）以北的多波束回波测深和地震剖面，已经确定了一个广泛的沉积体（轮廓扇）。水物理测深数据允许假设存在通过凯恩峡及其向北渗透的南极底水（AABW）溢流。在沉积物岩心（中更新世至全新世年龄）中，AABW的影响反映在高碳酸盐溶解速率和中碳酸盐溶解速率的变化上。
