Seismometer to Investigate Ice and Ocean Structure (SIIOS) Field Experiment: Greenland
To investigate the viability of a seismic experiment on an Ocean Worlds lander mission, we are undertaking a series of analog field studies to develop operational techniques and quantify the science return of a Seismometer to Investigate Ice and Ocean Structure (SIIOS).

To investigate the viability of a seismic experiment on an Ocean Worlds lander mission, we are undertaking a series of analog field studies to develop operational techniques and quantify the science return of a Seismometer to Investigate Ice and Ocean Structure (SIIOS). Specifically, we aim to achieve the following objectives: 1) Demonstrate the ability of a small aperture seismic arrays in a “lander-like” configuration to discriminate between ice/ocean/bedrock layers in Earth's cryosphere, and record the influence of diurnal motion, as an analog to Ocean Worlds. 2) Demonstrate the improved resolution of a small aperture array over a single instrument for the detection and location of passive seismicity and noise sources in an Ocean Worlds analog environment. 3) Develop protocols and requirements for spacecraft onboard generation of data products that preserve science results while also being compatible with data downlink limitations typical for missions deployed in the outer solar system. 4) Determine the most effective types of passive seismic sources (e.g., ice cracking) for measuring ice and liquid water structure.
