16 stations in 2011 and 20 stations in 2013 were sampled for Limacina helicina pteropods to measure shell dissolution. The data show the percentage of individuals with severe dissolution types (Type II and Type III) in relation to integrated aragonite saturation state in the upper 100 meters. The dataset was collected by NOAA and processed using scanning electron microscopy following established methods.
Use Cases
- Modeling the relationship between ocean acidification and shell dissolution based on aragonite saturation state
- Analyzing spatial patterns of pteropod shell damage across the California Current Ecosystem
- Comparing the severity of dissolution (Type II vs. Type III) between sampling years (2011 and 2013)
- Investigating correlations between pteropod abundance and carbonate chemistry conditions for the 2011 data
Strengths
- Data from two distinct sampling years (2011 and 2013) allowing for temporal comparison
- Analysis follows a standardized categorization scheme for dissolution types (Type II and Type III)
- Includes both dissolution percentages and, for 2011, abundance data (ind m-2)
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
