Virginia Coast Reserve site, station Phillips Creek Mouth, study of secchi disk depth (vertical) in units of meter on a monthly timescale

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 Virginia Coast Reserve (VCR)
contains secchi disk depth (vertical) measurements in meter units
and were aggregated to a monthly timescale.

EcoTrends项目由黛布拉·彼得斯博士（Jornada盆地长期生态研究计划（Long-Term Ecological Research, LTER），美国农业部农业研究局（USDA-ARS）Jornada实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究计划（LTER），美国农业部森林服务局（USDA-FS）卢奎洛实验林）于2004年创立，旨在支撑长期生态数据集的收集与分析工作。该项目属于大型综合研究工作，核心目标是提升长期生态数据的可获取性与应用价值。目前已有约50个由州政府与联邦政府资助的研究站点参与并为EcoTrends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局（ARS）、美国农业部森林服务局、美国能源部、美国地质调查局（USGS）及众多高校资助的站点。EcoTrends项目的数据集可通过探索性网络门户（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工作。作为长期生态研究计划溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，持续推进的数据汇编工作通过手动与自动两种处理方式进行更新。该网络门户是Jornada LTER与LTER网络办公室的合作成果。以下来自弗吉尼亚海岸保护区（Virginia Coast Reserve, VCR）的数据集包含以米为单位的垂直方向塞氏盘深度测量数据，并已聚合至月度时间尺度。
