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

Code and metrics for analyzing linear trends in marine cold spells and sea surface temperature from 1982 to 2016. The data, hosted by the Australian Ocean Data Network, can be used to plot global maps of trends in cold spell intensity, duration, and frequency. The record was last updated on 2026-07-13.

Use Cases

• Mapping global trends in marine cold spell intensity based on the provided metrics.
• Analyzing linear trends in sea surface temperature mean and variance over a 34-year period.
• Studying the relationship between changes in cold spell frequency, duration, and broader ocean temperature patterns.

Strengths

• Covers a 34-year time range from 1982 to 2016 for trend analysis.
• Provides multiple metrics for marine cold spells: mean intensity, duration, and frequency.

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.
