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.
