qPCR data for assessing the effects of seasonality, density, and tide phase on detection of invasive European green crab eDNA in Washington state, 2022-2023

The dataset supports studies performed in Washington state in 2022 and 2023 that investigated how detection of European green crab eDNA is affected by sampling season, green crab density, and the time at which samples are collected across a tide cycle. The data include sample site locations and descriptive categories, volume of water (L) filtered for eDNA analysis for each sampling event, qPCR quantification cycle (Cq) values, and the Y-intercept, slope, and R-squared value for each qPCR assay run.
