Description
Monitoring before, during, and after Tropical Cyclone Dominic captured sediment and water flux at Boulder Reef in the Northern Great Barrier Reef. The dataset, provided by the Australian Ocean Data Network, records water velocities up to 60 cm/s and sediment loads with particulate organic material up to ten times greater than particulate inorganic carbon. It also quantifies a terrestrial clay influx of 135-228 tonnes every five years, a pattern confirmed in Holocene core samples.
Use Cases
Modeling sediment transport dynamics based on recorded water velocities up to 60 cm/s
Analyzing the impact of tropical cyclones on reef carbonate budgets based on pre- and post-event sediment load comparisons
Studying terrestrial sediment influx to marine environments based on the detection of illite and kaolinite clays
Reconstructing long-term sedimentation patterns based on the reported 5000-year periodicity of clay deposition
Strengths
Captures a high-energy event with specific measurements: 430 mm of rainfall in 3 days and a river discharge of nearly 50,000 megalitres/day
Provides quantified sediment loads: reef-derived particulate organic material was up to ten times greater than particulate inorganic carbon by weight
Documents a multi-phase sediment pulse with specific timelines: a second terrigenous pulse arrived four days after the cyclone
Limitations
Column-level documentation is absent; field semantics must be inferred after download
Row count is unknown, which may limit suitability assessment
Data is provided in PDF and HTML formats, which may require extraction to be usable for analysis
