AKA: CZU wildfire geochemistry
Other ID: CZU wildfire geochemistry
Status: Completed
Organization(s): USGS, Pacific Coastal and Marine Science Center
Funding Program(s): Other (Other), Wildfire geochemistry: signatures and effects (GX24ZP00JTV0600)
Contact(s): Renee Takesue
Information Specialist(s): Renee Takesue
Data Type(s): Environmental Data: Meteorology, Location-Elevation: Navigation, Sampling: Chemistry
Scientific Purpose/Goals: Characterize sediment geochemical, carbon, and contaminant changes associated with wildfire and potential loading to coastal systems.
Vehicle(s): Mitsubishi Outlander G61-0912R
Start Port/Location: Santa Cruz, California
End Port/Location: Santa Cruz, California
Start Date: 2020-09-09
End Date: 2026-09-30
Equipment Used: Onset HOBO RG3-M Rain Gauge, Handheld GPS, Hand-grab sample
Information to be Derived: Grain size, carbon, charcoal, detrital zircon, carbon isotopes, radiocarbon, rare earth elements, metals, PAHs
Summary of Activity and Data Gathered: Stream nutrient samples were collected approximately monthly. Stream sediment was collected two or three times a year around the first flush, winter high flow, and low flow conditions. In situ ash was collected every six months.
Notes: End date was changed from original 3/31/21 to a 5-year period ending 9/30/26 to allow for sample collection for a weathering study post-fire.
