Tissue Concentrations and Congener Profiles of Harmful Algal Toxins in Seabirds, Forage Fish, and Other Organisms

These data are in four tables and contain results from screening tissues of marine organisms for the presence of harmful algal bloom (HAB) toxins: saxitoxin and its related congeners (STX) and domoic acid (DA). Samples collected by USGS or submitted to our laboratory by partners or other stakeholders are screened using commercially-available enzyme linked immunosorbent assays (ELISA). A subset of samples containing detectable levels of STX were subsequently analyzed using high-performance liquid chromatography (HPLC). The dataset herein consists of three tables the ELISA test results for STX and DA and HPLC summary results for STX for 1) birds, 2) fish, and 3) invertebrates. A subset of these data were previously published in the following data releases: https://www.doi.org/10.5066/P9UNY0FR and https://www.doi.org/10.5066/P9OK4I8M.
