Taxonomic composition of environmental DNA acquired by filtration from the St. Regis River, New York

Environmental DNA (eDNA) surveys have become important tools for monitoring aquatic biodiversity. Barcode sequencing of eDNA generates community profiles that, while potentially biased in both capture and amplification, can nonetheless yield high information content per unit cost. While factors affecting eDNA capture and amplification have been heavily studied, watershed-scale assessments of fish communities and our confidence in such have been less frequent. We performed an initial watershed-scale characterization of fish eDNA using rapid, low-volume filtering with replicate and control samples scaled for a single Illumina MiSeq flow cell, using the mitochondrial 12S ribosomal RNA locus for taxonomic profiling....

Child Item 4: Hydroacoustic Surveys, North Pacific and Bering Sea, 2012 and 2014

This is a child item of the USGS Data Release: https://doi.org/10.5066/F7TQ60GV These data comprise of hydroacoustic backscatter data along transects in the North Pacific and Bering Sea conducted in August 2012 and 2014. We echointegrated hydroactoustic backscatter and used that as a proxy for forage fish biomass. The dataset consists of comma delimited files for 120Hz frequency. Each file contains analysis exports from EchoView Software Pty Ltd. ver. 5.4.
