Marine Cold Spell Metrics and Surface Temperature Trends, 1982-2016

Australian Ocean Data Network provides code and metrics for analyzing marine cold spells. The data includes linear trends for surface temperature mean and variance, as well as mean intensity, duration, and frequency of marine cold spells from 1982 to 2016. This data can be used to plot global maps of these trend metrics.

Use Cases

• Mapping global trends in marine cold spell intensity based on the provided linear trend metrics.
• Analyzing changes in ocean surface temperature variability based on the variance trend data from 1982-2016.
• Studying the relationship between the frequency and duration of marine cold spells over a 34-year period.
• Visualizing spatial patterns of climate trends in ocean temperature extremes for regional impact assessments.

Strengths

• Covers a 34-year time period from 1982 to 2016 for trend analysis.
• Includes multiple metrics for marine cold spells: mean intensity, duration, and frequency.
• Data is structured for generating global geospatial maps of the calculated trends.

Limitations

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