Time series composite CTD profiles from R/V Hermano Ginés cruises in the Cariaco Basin from 1995 through 2017 (CARIACO Ocean Time-Series Program)

<p>The CARIACO Ocean Time-Series Program (formerly known as CArbon Retention In A Colored Ocean) started on November 1995 (CAR-001) and ended on January 2017 (CAR-232). Monthly cruises were conducted to the CARIACO station (10.50° N, 64.67° W) onboard the R/V Hermano Ginés of the Fundación La Salle de Ciencias Naturales de Venezuela. During each cruise, a minimum of four hydrocasts were performed to collect a suite of core monthly observations. We conducted separate shallow and deep casts to obtain a better vertical resolution of in-situ Niskin-bottles samples for chemical observations, and for productivity, phytoplankton, and pigment observations. One CTD composite profile was created for each cruise by stitching together the sections of the different cruise's CTD profiles at the depth interval where water samples were obtained. CTD’s Salinity, Oxygen, and Fluorescence where calibrated with in-situ measurements. The composite CTD profiles dataset is a complement of the hydrographic time series data obtained with the Niskin Bottle Samples (https://www.bco-dmo.org/dataset/3093). The following sections describe the methods used in collecting the core observations at the CARIACO station.<br /> <br /> Methodology published at CARIACO site (http://imars.usf.edu/publications/methods-cariaco)</p> <p>CARIACO Field Program general description (http://www.imars.usf.edu/cariaco)</p> <p>Additional funding support provided by:<br /> Fondo Nacional de Ciencia, Tecnología e Investigación, FONACIT (2000001702 and 2011000353), Venezuela.<br /> Ley Orgánica de Ciencia, Tecnología e Innovación, LOCTI (Estación de Investigaciones Marinas, 23914), Venezuela.<br /> Inter-American Institute for Global Change Research, IAI (IAI-CRN3094).</p>CARIACO海洋时间序列计划（CARIACO Ocean Time-Series Program，前身为CArbon Retention In A Colored Ocean）于1995年11月启动（项目编号CAR-001），2017年1月正式收官（项目编号CAR-232）。科考团队搭乘委内瑞拉拉萨勒自然科学基金会（Fundación La Salle de Ciencias Naturales de Venezuela）所属的“赫尔莫诺·希内斯号”（R/V Hermano Ginés）研究船，每月前往CARIACO站（北纬10.50°，西经64.67°）开展巡航科考。每次巡航至少完成4次水文剖面测量作业，以采集成套核心月度观测数据。为获取更高垂向分辨率的原位尼斯金采水器（Niskin-bottles）样品，用于化学观测、生产力、浮游植物及色素类研究，科考团队分别开展浅层与深层水文剖面测量作业。本数据集通过将不同航次的温盐深剖面仪（Conductivity, Temperature, Depth, CTD）在取水样深度区间的剖面片段拼接整合，为每一次巡航生成一条综合CTD剖面。CTD测得的盐度、溶解氧及荧光数据均通过原位测量完成校准。本综合CTD剖面数据集是尼斯金采水器样品（https://www.bco-dmo.org/dataset/3093）所获水文时间序列资料的补充数据集。下文将详述在CARIACO站开展核心观测的采集方法。 相关采样方法已发表于CARIACO官方站点（http://imars.usf.edu/publications/methods-cariaco） CARIACO野外计划总体说明可访问以下链接获取：http://www.imars.usf.edu/cariaco 本项目获得以下机构的额外经费支持： 1. 委内瑞拉国家科学、技术与研究基金（Fondo Nacional de Ciencia, Tecnología e Investigación, FONACIT），项目编号：2000001702、2011000353； 2. 委内瑞拉《科学、技术与创新组织法》（Ley Orgánica de Ciencia, Tecnología e Innovación, LOCTI），项目依托海洋研究站（Estación de Investigaciones Marinas），项目编号23914； 3. 美洲全球变化研究研究所（Inter-American Institute for Global Change Research, IAI），项目编号：IAI-CRN3094。
