Mysis diluviana data for CSMI 2013 from Lake Ontario

This database includes data from all large-mesh whole-water-column vertical net tows used to collect M. diluviana as part of the 2013 CSMI effort in Lake Ontario. These data were collected to allow the first estimation of lake-wide annual population dynamics of M. diluviana in Lake Ontario since 1995. The information necessary for these estimates is provided in this database. Three tables are included: SurveyData, VisitData, and MaturesData. These data were also collected for use in conjunction with results of several simultaneous efforts primarily focused on understanding spatial and food-web ecology of lower trophic levels (including M. diluviana) and prey fish. Several other relevant datasets exist. For instance, two M. diluviana datasets collected from Lake Ontario in 2013 were excluded from this dataset: 1) several large-mesh vertical net tows for M. diluviana which were sampled only a portion of the water column, and 2) a substantial volume of hydroacoustic data containing information on M. diluviana abundance, biomass, and fine-scale distribution patterns in the water column. Several other datasets exist, including (but not limited to) information regarding concentrations, densities, and distributions of: physical properties, chlorophyll, and algal, zooplankton, and prey fish communities.本数据库收录了2013年安大略湖CSMI项目中为采集M. diluviana所开展的全部大网目全水柱垂直拖网采样数据。本次采样旨在实现1995年以来首次对安大略湖全域M. diluviana年度种群动态的估算，本数据库提供了该估算所需的全部信息，共包含三张数据表：SurveyData、VisitData及MaturesData。 本数据集的采集同时服务于多项同期研究工作，这些研究主要聚焦于探究低营养级类群（含M. diluviana）与饵料鱼类的空间分布及食物网生态特征。此外尚有多项相关数据集存在。例如，有两份2013年从安大略湖采集的M. diluviana数据集未被纳入本数据集：其一为仅采集部分水柱的M. diluviana大网目垂直拖网采样数据；其二为包含M. diluviana丰度、生物量及水体中精细尺度分布模式信息的大量水声探测数据。另有其他多类数据集，涵盖（但不限于）物理参数、叶绿素浓度、藻类、浮游动物及饵料鱼类群落的浓度、密度与分布信息。
