High-frequency river thorium monitoring

Local Knowledge Graph (19 entities)

Knowledge graph centered on High-frequency river thorium monitoring with 19 nodes and 34 connections. Top connected: groundwater storage dynamics, spatiotemporal variability, concentration-discharge relationship, River thorium concentrations can record bedrock fr, critical zone.

Description

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.

Typical Equipment

• sample bottles
• 0.45 μm polyethersulfone syringe filters
• inductively coupled plasma mass spectrometer (ICP-MS)

Output Measurements

• thorium concentrations
• beryllium concentrations
• arsenic concentrations
• discharge measurements
