Ross Ice Shelf Seismic Response to Ocean Wave Vibrations

Seismic data records vibrations induced by ocean waves on the Ross Ice Shelf. Observations were made continuously from November 2014 to November 2016 using a deployed seismometer array. The project was conducted by researchers affiliated with AMD_USAPDC.

Use Cases

• Analyze flexural gravity wave signals to model ice shelf flexure from long-period ocean waves.
• Detect and catalog icequake events to assess fracturing and calving triggers.
• Correlate seismic signal amplitude and frequency with ocean swell (10-30s period) impacts.
• Map the propagation of wave-induced vibrations over distances of hundreds of kilometers from the ice edge.

Strengths

• Continuous observations over a two-year period from Nov 2014 to Nov 2016.
• Unique seismometer array deployment specifically on an ice shelf.
• Data captures two prevalent signal types: flexural gravity waves and icequakes.

Limitations

• Specific row count, column details, and file formats are unknown.
• Data coverage is limited to the Ross Ice Shelf and a two-year window.
• The dataset description lacks sample data or explicit data structure.
