An oceanography concept defining physical and chemical processes that control ocean structure and coastal dynamics. It governs circulation, stratification, sea level behavior, and exchanges of heat, salt, and dissolved species. It does not ensure local coastal outcomes without accounting for bathymetry, shoreline geometry, and forcing variability. It supports marine monitoring and coastal planning by linking ocean state to hazards and ecosystem conditions. The concept is generally stable, though observing systems and model resolution improve over time.

Principle

Datasets must be georeferenced, time‑stamped, quality controlled, accompanied by provenance and datum information, and structured so users can reproduce analyses, convert units, and propagate uncertainty appropriately.

Demonstration

A publicly archived dataset bundles hourly tide‑gauge records from a coastal network, collocated anemometer and barometer series, high‑resolution bathymetry, modeled hindcasts for several past storms, shapefiles of observed inundation extents, and README metadata describing QA/QC and datum conversions.

Misapplication

Merging records with inconsistent datums or time zones without correction, removing or failing to record provenance and QA/QC flags, or selectively publishing only favorable model runs creates biases and undermines reproducibility.

Consequence

A well‑constructed dataset enables model validation, reproducible research, operational forecast ingestion, comparative studies across events, and evidence‑based decision making by providing trustworthy inputs and clear uncertainty characterization.

Reversal

Raw sensor dumps lacking metadata, undocumented preprocessing, or proprietary black‑box model outputs without provenance limit reuse and may produce misleading conclusions if used without caution.

Boundary

Refers specifically to data products assembled for storm surge purposes; excludes unrelated environmental datasets unless explicitly integrated and documented, and does not by itself guarantee data quality beyond documented QA/QC procedures.

Semantic Tension

Tension between raw observational archives (complete but noisy) and curated standardized datasets (cleaner but filtered); between open, fully documented datasets and proprietary operational products with restricted metadata.

Synthesis

A Storm Surge Dataset is a documented, quality‑controlled collection of observations, model outputs, and geospatial layers assembled with provenance and datum information to support analysis, model validation, operational use, and reproducibility in surge science.
