Time-Series of Phytoplankton Taxonomy and Density collected by the CARIACO Ocean Time-Series Project from November 1995 to January 2017

<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. The program studied the relationship between surface primary production, physical forcing variables like the wind, and the settling flux of particulate carbon in the Cariaco Basin. This depression, located on the continental shelf of Venezuela, shows marked seasonal and interannual variation in hydrographic properties and primary production (carbon fixation rates by photosynthesis of planktonic algae).</p> <p>One of the monthly measurements taken by the program was water sampling at different depths for phytoplankton taxonomy (occurrence and density). Those water samples were collected with Niskin bottles during the first CTD Cast of the morning at 1, 7, 25, 35, 75, and 100 m depth. Phytoplankton taxonomy and density was determined at each depth at the level of species or genera. Values of zero are real and denote that a specific species was not found at that cruise/depth.&nbsp;</p> <p>Web page of the CARIACO Ocean Time-Series Program: http://imars.usf.edu/cariaco</p> <p>A complete list of publications from the CARIACO Ocean Time-Series project can be found at: http://imars.usf.edu/view/biblio/803738/year</p> <p>These data were also funded by the following awards:<br /> - 23914: Ley Orgánica de Ciencia, Tecnología e Innovación, LOCTI (Estación de Investigaciones Marinas), Venezuela.<br /> - 2011000353: 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“有色海洋中的碳固存”（CArbon Retention In A Colored Ocean））于1995年11月启动（项目编号CAR-001），并于2017年1月正式收官（项目编号CAR-232）。该计划依托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）科考调查船，每月前往CARIACO站位（10.50°N，64.67°W）执行科考航次。本计划核心研究内容为卡里亚科盆地内表层初级生产力、风力等物理强迫变量与颗粒碳沉降通量之间的关联机制。该盆地坐落于委内瑞拉大陆架之上，其水文特性与初级生产力（浮游藻类光合作用固碳速率）呈现显著的季节与年际变化特征。 该计划开展的常规月度观测项目之一，为在不同深度采集水样以开展浮游植物分类学研究（涵盖物种出现情况与种群密度）。水样采集于当日首次温盐深剖面测量（Conductivity, Temperature, Depth，简称CTD）测站期间，采用尼斯金采水器（Niskin bottles）在1、7、25、35、75及100米深度完成采集。研究人员在各深度层级以物种或属级分辨率开展浮游植物分类鉴定与密度统计，数值为0的记录均为真实有效，代表对应航次的该深度未检出特定物种。 CARIACO海洋时间序列计划官方网页：http://imars.usf.edu/cariaco 该项目的完整学术出版物列表可通过以下链接查阅：http://imars.usf.edu/view/biblio/803738/year 本数据集的资助来源如下： - 项目编号23914：委内瑞拉《科学、技术与创新组织法》（Ley Orgánica de Ciencia, Tecnología e Innovación, LOCTI）下属海洋研究站专项经费。 - 项目编号2011000353：美洲全球变化研究研究所（Inter-American Institute for Global Change Research, IAI）资助项目（IAI-CRN3094）。
