Knowledge graph centered on High-frequency river thorium monitoring with 20 nodes and 41 connections. Top connected: groundwater storage dynamics, spatiotemporal variability, concentration-discharge relationship, River thorium concentrations can record bedrock fr, critical zone.
Frequent collection and ICP-MS analysis of river water samples to detect thorium concentration excursions as indicators of bedrock fracture processes. Samples collected up to daily frequency and analyzed for ultra-trace thorium concentrations.
Synthesized from method descriptions across 1 paper using this protocol.
Steps below were extracted from the paper that introduces this protocol — River thorium concentrations can record bedrock fracture processes including some triggered by distant seismic events (2023), Nature Communications. Implementations in other papers (listed below) may differ.
