Scallop Mortality and Seismic Survey Impact Data in Bass Strait, 2006-2016

Field-based data assesses the potential impacts of marine seismic surveys on scallops in the Bass Strait, Australia. The study includes dredging and Autonomous Underwater Vehicle surveys of two scallop species before and after a 2015 seismic event, alongside MODIS satellite-derived sea surface temperature data from 2006 to 2016. Results show no direct mortality from the 2015 survey but link a 2010 mortality event to a thermal spike coinciding with a seismic survey.

Use Cases

• Assessing sub-lethal effects of seismic surveys on scallops based on field-based dredging and AUV imagery.
• Correlating mass mortality events with environmental stressors using long-term MODIS sea surface temperature data.
• Informing regulatory assessments for marine seismic survey applications based on paired in-situ and remote sensing data.

Strengths

• Data integrates three distinct field-based methods: dredging, AUV deployment, and satellite remote sensing.
• The study provides ecologically realistic results by coupling in-situ data with commercial seismic array considerations.
• Temporal coverage includes observations before, two months after, and ten months after a 2015 seismic survey.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
