Bass Strait, Australia, is the geographic focus of this dataset investigating the potential impacts of marine seismic surveys on scallops. The data includes results from three field-based methods: dredging and Autonomous Underwater Vehicle (AUV) deployments for two scallop species (Pecten fumatus, Mimachlamys asperrima) before and after a 2015 survey, and MODIS satellite-derived sea surface temperature patterns from 2006 to 2016. The study, published in Marine Pollution Bulletin in 2018, found no evidence of scallop mortality from the 2015 survey but identified a thermal spike coinciding with a 2010 mortality event.
Use Cases
- Assessing sub-lethal effects of seismic surveys on scallop populations based on field-based dredging and AUV imagery.
- Correlating marine mortality events with environmental stressors using MODIS satellite-derived sea surface temperature time series.
- Evaluating the ecological realism of seismic survey impact studies based on the use of in situ data and commercial seismic arrays.
- Comparing the response of different scallop species (Pecten fumatus, Mimachlamys asperrima) to underwater noise pollution.
Strengths
- Employs three complementary field-based methods (dredging, AUV imagery, satellite remote sensing) for a multi-faceted assessment.
- Includes temporal data spanning a decade (2006-2016) for sea surface temperatures.
- Provides ecologically realistic results by coupling in situ data with consideration of commercial seismic arrays.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific study region in Bass Strait.
