California Current Ecosystem site, station Ohman Region: subset of CalCOFI stations inshore and nearshore in the Southern California Bight region; CalCOFI lines 80-93, stations from shore offshore to station 70, study of biomass of zooplankton in units of Log10(millilitersPerSquareMeter) on a yearl

The EcoTrends project was established in 2004 by Dr. Debra Peters
(Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and
Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest)
to support the collection and analysis of long-term ecological datasets.
The project is a large synthesis effort focused on improving the accessibility
and use of long-term data. At present, there are ~50 state and federally funded
research sites that are participating and contributing to the EcoTrends project,
including all 26 Long-Term Ecological Research (LTER) sites and sites funded by
the USDA Agriculture Research Service (ARS), USDA Forest Service,
US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal
(http://www.ecotrends.info). This web portal enables the continuation of data
compilation and accessibility by users through an interactive web application.
Ongoing data compilation is updated through both manual and automatic
processing as part of the LTER Provenance Aware Synthesis Tracking
Architecture (PASTA). The web portal is a collaboration between the Jornada LTER
and the LTER Network Office. The following dataset from California Current Ecosystem (CCE)
contains biomass of zooplankton measurements in Log10(millilitersPerSquareMeter) units
and were aggregated to a yearly timescale.

生态趋势项目（EcoTrends）由黛布拉·彼得斯博士（乔纳达盆地长期生态研究站，美国农业部农业研究服务局乔纳达实验牧场，Jornada Basin LTER, USDA-ARS Jornada Experimental Range）与阿里尔·卢戈博士（卢奎洛长期生态研究站，美国农业部林业局卢奎洛实验森林，Luquillo LTER, USDA-FS Luquillo Experimental Forest）于2004年创立，旨在支撑长期生态数据集的采集与分析工作。本项目为一项大型综合研究工作，核心目标是提升长期数据的可获取性与利用率。目前，共有约50个由州政府及联邦政府资助的研究站点参与并为生态趋势项目贡献数据，其中涵盖全部26个长期生态研究（Long-Term Ecological Research, LTER）站点，以及由美国农业部农业研究服务局（ARS）、美国农业部林业局、美国能源部、美国地质调查局（USGS）及众多高校资助的研究站点。生态趋势项目的数据集可通过探索式网络门户（http://www.ecotrends.info）获取。该门户依托交互式网络应用程序，支持用户持续开展数据汇编与数据获取操作。作为长期生态研究溯源感知综合跟踪架构（LTER Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，正在进行中的数据汇编工作通过人工与自动两种处理方式完成更新。该网络门户由乔纳达LTER与LTER网络办公室合作开发。本部分来自加州洋流生态系统（California Current Ecosystem, CCE）的数据集，包含以Log10(毫升每平方米)为单位记录的浮游动物生物量数据，且已按年时间尺度完成聚合。
