Biogeochemical and microbiological variables measured by CTD and Niskin bottles from the Hermano Gines in the Caribbean Sea for the CARIACO Ocean Time-Series Program from 1995-11-13 to 2015-11-14 (NCEI Accession 0164194)

The goal of this project was to examine the interrelationship between microbial activity and water column geochemistry in the world’s largest, truly marine anoxic system, the Cariaco Basin. This project focused on microbial cycling of carbon, sulfur, and nitrogen occurring at depths where waters transition from oxic to anoxic to sulfidic. Over the 21 year program, the Stony Brook team typically staged cruises semi-annually during upwelling (Mar-May) and non- upwelling (Oct-Nov) periods. These 24-hour cruises were usually within a week of the routine monthly cruises staged by the Fundacion La Salle and University of South Florida team. Most cruises occupied only the CARIACO Ocean Time-Series station. On cruises 108 to 132, additional stations in the western basin and on the sill to the north of the Cariaco station were also sampled. Locations are given in the database. Data provided in a single MS Excel spreadsheet.

本项目旨在探究全球规模最大的纯海洋缺氧系统——卡里亚科盆地（Cariaco Basin）中，微生物活动与水柱地球化学之间的相互关联。本项目聚焦于水体从有氧向缺氧、再向硫化转变的深度区间内发生的碳、硫、氮微生物循环过程。在为期21年的项目周期中，石溪大学（Stony Brook）团队通常在上升流期（3月至5月）与非上升流期（10月至11月）每半年组织一次科考航次。这类持续24小时的航次通常安排在拉萨尔基金会（Fundacion La Salle）与南佛罗里达大学（University of South Florida）团队开展的常规月度航次前后一周内。多数航次仅以卡里亚科海洋时间序列站（CARIACO Ocean Time-Series station）为采样位点。在第108至132号航次中，研究团队同时对盆地西部以及卡里亚科站北侧海槛处的额外采样位点开展了采样。采样位点的具体信息已收录至数据库中。数据集以单份微软Excel（MS Excel）表格形式提供。
