Harmful Algal Bloom (HAB) data collected by the Scripps Institution of Oceanography and made available by the Southern California Coastal Observing System (SCCOOS)

CalHABMAP provides updates on current algal blooms and facilitates information exchange among HAB researchers, managers and the general public in California. A major component of this program is regional HAB monitoring. Water samples and net tows are collected once per week to monitor for HAB species and naturally occurring algal toxins. Water quality data including temperature, salinity, and nutrients are also collected.

Domoic acid and saxitoxin in seabirds from California and Rhode Island 2015-2017

As harmful algal blooms (HABs) increase in magnitude and duration worldwide, they are becoming an expanding threat to marine wildlife. Over the past decade, domoic acid (DA) and saxitoxin (STX) have been increasingly problematic bicoastally in the United States. We investigated pooled seabird mortality data from opportunistic sampling events between 2007-2018, across three states, to examine the patterns and role of DA and STX in seabird mortality events from the continental United States. Patterns in DA and STX levels and affected tissue type were reviewed, and two specific accounts of localized and pervasive event types were examined. There has been increased toxin detection with expanded tissue testing during...

Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC/MS/MS) analysis of cyanotoxins and algal toxins in estuary samples collected from California, USA, in 2016-17

Cyanobacteria known to produce cyanotoxins have been reported worldwide. As monitoring efforts have improved, they have been detected in not only freshwater, but also in estuary and marine waters. To assess the occurrence of cyanotoxins and algal toxins in California estuaries, the NOAA MERHAB funded project collected samples monthly from 11 Californian estuary locations, with 5 locations sampled in 2016 as event response. This data release includes liquid chromatography triple quadrupole mass spectrometry (LC/MS/MS) results for 21 cyanotoxins and algal toxins in estuary samples collected from California in 2016-2017.

Results of algal toxin testing from wildlife mortality submissions to the National Wildlife Health Center

This data set is composed of all animals received as a diagnostic submission to the USGS National Wildlife Health Center for which algal toxin testing was performed from November 1998 to January 2018. Birds with a histologic diagnosis of avian vacuolar myelinopathy, a disease caused by the algal toxin aetokthonotoxin, are also included. Algal toxins tested for include brevetoxin, cylindrospermopsin, domoic acid, microcystin, and saxitoxin. Case-accession number, species, state collected, month and year collected, and detection or non-detection of the algal toxin is reported.

Cyanotoxin, chlorophyll-a, and cyanobacterial toxin genetic data for samples collected at eleven large river sites throughout the United States, June through September 2017

This U.S. Geological Survey (USGS) data release provides discretely measured cyanotoxin, chlorophyll-a, and cyanobacterial toxin genetic data for samples collected from eleven large river sites throughout the United States, from June through September 2017. Discrete water-quality samples were analyzed for cyanotoxins (anatoxin, cylindrospermopsin, microcystin, and saxitoxin), chlorophyll-a, and cyanobacterial toxin genetics as part of a National Water-Quality Assessment Project pilot study to describe potential cyanotoxin occurrence in the Nation's large rivers.

Data release for Investigation of a largescale common murre (Uria aalge) mortality event in California in 2015

During 2015, beachcast bird survey programs (Beach Watch and BeachCOMBERS) reported higher than average deposition of common murres (Uria aalge) on central and northern California beaches from August through December. Increased common murre mortality was not reported for southern California beaches. International Bird Rescue (IBR) located in Fairfield, CA and other coastal wildlife rehabilitation centers received more than 1,000 live, stranded and debilitated murres from Sonoma County to San Luis Obispo County during August – October. Approximately 2/3 of birds admitted to IBR were after-hatch-year birds in emaciated body condition and in various stages of molt, with extremely worn plumage. To determine the probable...
