EMPA 2021 Trap Data - Biomass and Length

The overall goal of the Estuary Marine Protected Area (EMPA) Monitoring Program is to establish a monitoring framework, including data collection, analysis, synthesis, and reporting to determine the health of estuaries in California and the efficacy of MPA designation in estuaries. As part of the initial phases of the program, we developed standard protocols to assess key estuarine features across different estuaries, coupled with standard data templates and guidance on analysis, synthesis, and reporting, focused on four guiding principles: flexibility, comparability, interpretability, and practicality. We developed 14 SOPs and piloted the framework at 15 estuaries in 2021. For more details on the EMPA program and framework, see https://empa.sccwrp.org. This dataset includes the crab biomass and fish length data from the crab traps in SOP 10. Minnow traps and shrimp pots were deployed at each sampling station within an estuary. Each fish or invertebrate was identified to species, and total abundance was reported by species. Crabs were weighed and fish standard length was measured. For more details, see SOP 10 on https://empa.sccwrp.org. To simplify data usability, fields from both data and metadata tables have been combined to provide the user with a merged dataset. The metadata table is also included in standalone format.

河口海洋保护区（Estuary Marine Protected Area, EMPA）监测计划的整体目标是构建一套涵盖数据采集、分析、整合与报告流程的监测框架，用以评估加利福尼亚州河口的健康状况，以及河口内海洋保护区（Marine Protected Area, MPA）划定的有效性。作为该计划初期阶段的工作内容，我们制定了用于评估不同河口关键河口特征的标准规程，并配套了标准数据模板以及分析、整合与报告指南，整套体系遵循四大核心原则：灵活性、可比性、可解释性与实用性。我们共制定了14项标准作业程序（Standard Operating Procedure, SOP），并于2021年在15个河口开展了该框架的试点工作。如需了解EMPA计划与监测框架的更多细节，请访问https://empa.sccwrp.org。本数据集包含SOP 10中蟹笼采集的蟹类生物量与鱼类体长数据。各河口的所有采样站点均布设了幼鱼诱捕笼与虾笼。所有采集到的鱼类与无脊椎动物均鉴定至物种水平，并按物种统计总个体丰度。对蟹类进行称重，并测量鱼类的标准体长。如需了解更多细节，请访问https://empa.sccwrp.org查阅SOP 10。为提升数据易用性，本数据集将数据表格与元数据表的字段进行了合并，以方便用户使用；同时还提供了独立格式的元数据表。
