Three field-based methods were used to investigate the potential impact of marine seismic surveys on scallops in the Bass Strait, Australia. Dredging and Autonomous Underwater Vehicle imagery assessed two scallop species before, two months after, and ten months after a 2015 survey. MODIS satellite data provided sea surface temperature patterns from 2006 to 2016, revealing a thermal spike in 2010 coinciding with a scallop mortality event.
Use Cases
- Assessing scallop mortality and sub-lethal effects based on dredging and AUV survey data before and after seismic events.
- Correlating environmental stressors with biological impacts based on MODIS-derived sea surface temperature time series from 2006-2016.
- Informing regulatory assessments for marine seismic survey applications based on paired field-based monitoring methods.
Strengths
- Data collection employed three complementary field-based methods: dredging, AUV deployment, and MODIS satellite remote sensing.
- Temporal coverage includes specific surveys in 2010 and 2015, with MODIS data spanning a decade from 2006 to 2016.
- Study design provided ecological realism by using commercial seismic arrays and paired field components as a failsafe.
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.
