Contact(s): Amy East Information Specialist(s): Andrew Ritchie Data Type(s): Location-Elevation: Navigation, Sampling: Geology Scientific Purpose/Goals: Collect suspended-sediment samples from a bridge-mounted sampling station on the San Lorenzo River (pedestrian bridge between Water St and Soquel Ave), opposite the downtown Trader Joe's. We intend to sample every hour or two (more often on the highest flows) throughout rainfall events as part of a multi year study of how antecedent conditions affect coastal watershed sediment yield in this area. Vehicle(s): None Start Port/Location: none End Port/Location: none Start Date: 2008-11-02 End Date: 2024-09-30 Equipment Used: GPS, samples Information to be Derived: suspended sediment/sediment transport in river Summary of Activity and Data Gathered: Collected 384 water samples between water-years 2009 and 2024 that were processed at CA Water Science Center field station in Santa Cruz for suspended-sediment concentration and sand break. Notes: Data spanned the wettest water-year on record for the San Lorenzo watershed.

Samples were collected during 2-, 5- and 10-year flood events.) Polycyclic aromatic hydrocarbons (PAHs) in the San Lorenzo River, Santa Cruz, California, USA, from 2015 to 2016 (Polycyclic aromatic hydrocarbons (PAHs) are reported for water samples collected from the San Lorenzo River water during the rainy seasons from 2015 to 2016. Samples were collected during 2-, 5- and close to 10 year flood events.) |
