A 2018 study by Geoscience Australia used three field-based methods to assess potential impacts of marine seismic surveys on scallops in the Bass Strait. Dredging and Autonomous Underwater Vehicle imagery for two scallop species were collected 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 coinciding with a 2010 mass mortality event.
Use Cases
- Modeling the relationship between seismic survey activity and scallop mortality based on paired field observations.
- Analyzing long-term sea surface temperature anomalies using MODIS satellite data from 2006–2016.
- Assessing sub-lethal effects on marine bivalves using Autonomous Underwater Vehicle imagery.
- Informing regulatory assessments for marine seismic survey applications based on ecologically realistic field data.
Strengths
- Study design includes temporal data points (before, 2 months after, 10 months after) for the 2015 seismic survey.
- Integrates multiple data sources: in-situ dredging, AUV imagery, and a decade of MODIS satellite remote sensing.
- Focuses on two specific scallop species (Pecten fumatus and Mimachlamys asperrima) in a defined geographic region.
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.
