Hourly Soil Moisture Data from Deception Island Permafrost Network

Deception Island in Antarctica provides raw hourly soil moisture measurements at different depths, collected since 2023. The data is acquired from Crater Lake PT stations within the PERMATHERMAL monitoring network. The network is led by Dr. Miguel Ángel de Pablo of Universidad de Alcalá and began operations in 2000.

Use Cases

• Modeling soil moisture dynamics at different depths using hourly time-series data from PT stations.
• Analyzing seasonal thaw patterns by correlating soil moisture with temperature and snow depth sensor data.
• Studying permafrost stability in volcanic Antarctic environments using long-term monitoring network records.

Strengths

• Hourly temporal resolution provides detailed diurnal and seasonal cycles.
• Data collection spans multiple stations within a focused Antarctic volcanic island environment.
• Network has operated since 2000, supporting long-term trend analysis.

Limitations

• Data is described as raw and unprocessed, requiring significant quality control.
• Specific row counts, column details, and sensor depth specifications are unknown.
• Geographic scope is limited to two Antarctic islands, reducing generalizability.
