Mekong Delta Mangrove Hydrodynamics from Mini Buoys, June-August 2022

Acceleration data from 19 low-cost, bottom-mounted 'Mini Buoy' floats deployed at three sites in the Mekong Delta, Vietnam. The data were collected between 25 June and 31 August 2022 to identify hydrological tipping points at eroding and expanding mangrove forest edges. The dataset is hosted by the Environmental Information Data Centre and includes gravity-compensated acceleration values in g-force at sub-minute intervals.

Use Cases

• Identifying hydrological tipping points between expanding and eroding mangrove edges based on acceleration data.
• Analyzing wave and current energy at the sediment-water interface using gravity-compensated g-force measurements.
• Comparing hydrodynamic conditions across three distinct mangrove sites (Ca Mau, Kien Giang, Soc Trang) in the Mekong Delta.
• Calibrating or validating coastal erosion models with in-situ, sub-minute interval sensor data.

Strengths

• Data spans a specific 68-day field campaign from 25-06-2022 to 31-08-2022.
• Includes measurements from 19 distinct sensor units (7 in Ca Mau, 5 in Kien Giang, 7 in Soc Trang).
• Provides high-temporal-resolution data recorded at sub-minute intervals.
• Data is gravity-compensated, which likely reduces noise for analysis of hydrodynamic forces.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale ML tasks.
• Data may reflect geographic and temporal bias inherent to the specific 2022 campaign in the Mekong Delta.
