POD! Environmental Monitoring Program (IEP) benthic macroinvertebrate data

These files have count data for benthic macroinvertebrates collected in each sample for the three longest running stations of IEP's Ecological Monitoring Program. Convert to density (org/m2): multiply by 19 (size of ponar is .053m2 and mesh size is .595mm).本数据集涵盖IEP生态监测项目（IEP's Ecological Monitoring Program）三个长期运行监测站各采样批次中采集的底栖大型无脊椎动物（benthic macroinvertebrates）计数数据。若需将计数数据转换为密度单位（org/m²），需乘以系数19：该系数由采泥器（ponar）的采样面积0.053m²与网孔尺寸0.595mm计算得到。
