These data include WATER DEPTH, SPECIES IDENTIFICATION, SPECIES IDENTIFICATION - LIFE STAGE, TAXONOMIC CODE and species abundance. The instruments used to collect these data include net. These data were collected by William T. Peterson of Northwest Fisheries Science Center - Newport as part of NEP. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NODC on 2013-11-01.

The following is the text of the abstract provided by BCO-DMO:

This project was designed to make a comparison of the effects of coastal upwelling on the population dynamics and vital rates of the euphausiids Euphausia pacifica and Thysanoessa spinifera in the Northern California Current, north and south of Cape Blanco, Oregon.
These data are part of a project which describes the population dynamics of these two GLOBEC target organisms. The nets sampled along several transect lines off the central Oregon coast for the purpose of describing temporal variations in euphausiid abundance, recruitment, vital rates and production. A high-frequency sampling program will be supplemented with bimonthly cruises sampling along four transect lines: two off Oregon (Newport and Coos Bay) and two off northern California (Crescent City and Eureka) during GLOBEC Long-Term Observations Program (L-TOP) cruises. Data from these survey cruises will provide information on spatial variations in euphausiid biomass, numerical abundance, vital rates and production in the waters throughout the GLOBEC study region (Newport OR south to Eureka CA). The project proposed here has four objectives:

(1) determine the seasonal cycles of abundance of the two euphausiid species in relation to interannual variations in circulation, hydrography and upwelling;
(2) determine the seasonal, interannual and spatial variations in egg production rates, cohort development, and recruitment as a function of upwelling and phy toplankton blooms;
(3) examine the seasonal, interannual and spatial variations in mortality rates and production as a means to develop a better understanding of euphausiid population dynamics; and
(4) determine overwintering strategies and the role of seasonal reversals in circulation and the spring transition in redistributing euphausiids in shelf and slope waters.
All of the above data will be passed to one of the GLOBEC modelers (H. Batchelder, Univ. of California at Berkeley) who is developing an individual-based model for both euphausiid species; the proposed work is presented in the context of examining the relationship between the ecology of euphausiids and salmonid growth and survival.
The VPT data are organized on the GLOBEC server by cruise within year. The master page (Level 0) lists all of the cruises in chronological order. Clicking on a cruise will show all of the casts collected/processes from that cruise (Level 1). Clicking on a cast will bring up the Level 2 file that shows a single line with additional header information for a sample. Clicking on the sample_id (always "1" for this type of data) will display the Level 3 data, which are the actual taxonomic categories and abundances for that particular sample. Additional info about the variables are described below.

本次数据集涵盖水深、物种鉴定、物种鉴定-生活史阶段、分类学编码以及物种丰度等信息。采集该类数据所使用的仪器为网具。这些数据由美国西北渔业科学中心纽波特分部的William T. Peterson作为NEP项目的一部分采集完成。生物与化学海洋学数据管理办公室（Biological and Chemical Oceanography Data Management Office, BCO-DMO）于2013年11月1日将这些数据提交至国家海洋数据中心（National Oceanographic Data Center, NODC）。

以下为BCO-DMO提供的项目摘要文本：
本项目旨在对比海岸上升流对北加利福尼亚海流区域内，俄勒冈州布兰科角南北两侧的两种磷虾类物种——太平洋磷虾（Euphausia pacifica）和Thysanoessa spinifera的种群动态与生命速率的影响。
本数据集所属项目旨在描述这两种全球海洋生态系统动力学研究（Global Ocean Ecosystem Dynamics, GLOBEC）目标物种的种群动态。研究团队沿俄勒冈州中部海岸沿线的多条断面进行拖网采样，以阐明磷虾类丰度、补充量、生命速率与生产力的时间变化特征。在全球海洋生态系统动力学长期观测计划（Long-Term Observations Program, L-TOP）航次期间，高频采样计划将辅以双月航次采样，采样断面共4条：2条位于俄勒冈州沿岸（纽波特与库斯湾），2条位于北加利福尼亚沿岸（克雷森特城与尤里卡）。上述调查航次所获数据，将为GLOBEC研究区域（俄勒冈州纽波特向南至加利福尼亚州尤里卡）内的磷虾类生物量、数值丰度、生命速率与生产力的空间分布差异提供支撑。
本拟建项目共包含4项研究目标：
1. 明确两种磷虾物种丰度的季节周期，及其与环流、水文环境及上升流的年际变化之间的关联；
2. 阐明产卵速率、世代发育、补充量随上升流与浮游植物水华的季节、年际及空间变化规律；
3. 探究死亡率与生产力的季节、年际及空间变化特征，以深化对磷虾类种群动态的认知；
4. 确定磷虾类的越冬策略，以及环流季节逆转与春季跃变在磷虾类在陆架与斜坡水域重新分布过程中的作用。
上述所有数据将移交至GLOBEC模型开发者之一——加州大学伯克利分校的H. Batchelder，其正针对这两种磷虾物种开发基于个体的模型。本拟建研究将围绕磷虾类生态学与鲑科鱼类生长及存活之间的关联展开。
VPT数据按年度航次整理存储于GLOBEC服务器中。主页面（0级页面）按时间顺序列出所有航次。点击任一航次，将显示该航次采集/处理的所有测站（1级页面）。点击某一测站，将打开2级文件，该文件以单行形式展示样本的附加头文件信息。点击样本ID（此类数据的样本ID恒为"1"），将显示3级数据，即对应样本的实际分类学类别与丰度信息。关于变量的更多说明如下。
