Coastal Archive - Tide/Wave/Current/Bathymetry

Foundation for Research Science and Technology (Hazards Programme) supported. Purpose: Various projects.

Tide/Wave/Current/Bathymetry plus other info as available e.g. sediment cores.

Whangapoua, Wilson, Tairua, Wharekawa, Mercury Bay, Cooks Beach see spreadsheet

Various projects spanning last 20 years to make up hindcast data. Includes university data.

side-scan sonar, current metres, wave buoys, tide guages, hindcast wave model (> 1 km offshore). Frequency of collection: Various

Some historic data measured with low-tech instruments therefore limited detail available. Gaps in collection: Various Data quality: none for field work, NIWA QC for archiving. Attribute accuracy: Field equipment various (see appropriate technical reports). Calibration details given in client reports – accuracy dependant on application. Completeness: no extra info deemed necessary.

electronic, reports, Digital Format: standard text files, GIS layer (to come)

Ship movement Port design Hazard identification Estuary impacts

Available in summarised form (GIS layer). Contact NIWA for full data. Sensitivity/Confidentiality: Contact NIWA

Continuously updated. GIS layer in prep.

Many theses have bathymetry as well. Additional comments: Being worked at present to pull together all the different datasets. John to email through spreadsheet on data info. Related to Terry Hume's Estuary Classification. Used in the Physical Hazards Programme. Related information: NIWA wave model
