Averaged bottom temperature and dissolved oxygen in and around the Cape Canyon

Submarine canyons are internationally reported to enhance upwelling and heterogeneity. However, in South Africa such studies remain limited and thus a knowledge gap in regional submarine canyon dynamics still exists. To address this gap, the Department of Forestry, Fisheries and the Environment: Oceans and Coasts initiated a multi-disciplinary expedition onboard the RV Algoa (March 2016-2018) where oceanographic data, amongst other datasets, was collected within a 5x5 nautical mile distance. The benthic stations were linked to the associated mean bottom temperature and dissolved oxygen profiles.

国际间报道称，海底峡谷可增强上升流和异质性。然而，在南非洲，此类研究仍较为有限，因此在该地区海底峡谷动力学方面仍存在知识空白。为填补这一空白，南非林业、渔业与环境保护部（Oceans and Coasts）发起了多学科探险活动，于2016年至2018年期间乘坐RV Algoa号进行考察，在此期间收集了包括海洋学数据在内的多个数据集，采集范围在5x5海里之内。海底测站与相应的平均底部温度及溶解氧剖面数据相联系。
