Why was the data set created?

To collect research-grade scientific data to provide baseline measurements and for nearshore circulation studies.

How was the data set created?

1. From what previous works were the data drawn?
2. How were the data generated, processed, and modified?

   Date: Unknown (process 1 of 1)

   Parameters: * DYD Decimal year day 2001; dates/times are local Hawaiian Standard Time (GMT-11:00). * h Water depth in meters, calculated as the mean water depth from each hourly 512 s time series record. * Hs - Significant wave height in meters; derived from the zeroth moment of the reported energy spectrum. Described as the "average height of the one third highest waves in the record". The US Army Corps of Engineers, Shore Protection Manual, 3-11, states that a useful estimate of significant wave height in deep water is defined as: Hs~4*sigma, where sigma is the standard deviation of the wave record. Statistically, the maximum wave height in the record is Hmax ~ 9*Hs/5. * Tp - Peak period, in seconds; inverse of the frequency with the highest energy in the reported spectrum.

   A NIWA Dobie-A non-directional wave gauge was used to acquire this dataset. The Dobie was used in Time Series mode and thus recorded a time series of pressure, which was converted to water depth assuming a water density and atmospheric pressure. Significant wave height (Hs) and dominant wave period (Td) were computed from these 512 s time series of water depth at 2 Hz using the US Army Corps of Engineers (1989) SUPERDUCK spectral method. The high-frequency and low-frequency cut-offs were 0.04 Hz / 25 s and 0.25 Hz / 4 s, respectively.
