Description:

Abstract:

Time series data of wave height and water surface elevation were acquired for 100 days at three locations off of the island of Nanumanga, three locations off of the island of Nanumea, three locations off of the island of Nui, two locations off of the island of Nikulaelae, and two locations off of the island of Niulakita, in the island nation of Tuvalu, in support of a study on the coastal circulation patterns and the transformation of surface waves over the coral reefs. The relative placement of sensors on the reefs were as follows: TVL19NG3, TVL19NM1, TVL19NU1, TVL19NK1 and TVL19NL1 – offshore TVL19NG1, TVL19NM2 and TVL19NU2 – reef crest TVL19NG3, TVL19NM3, TVL19NU3, TVL19NK2 and TVL19NL2 – reef flat

Purpose:

The continuous measurements of waves and water levels from these instrument deployments provide information on the variability of waves on the coral reefs of Tuvalu. These data will be used to study the transformation of waves over the reef and how this process contributes to water levels, runup and the potential for flooding of the coast.

No formal assessment of vertical accuracy was performed. The stated accuracy of the pressure sensor on the wave gauge is +/- 0.01 decibars, which is approximately equivalent to 0.01 meters.

Lineage:

Process_Step:

Process_Description:

Wave gauges owned by the U.S. Geological Survey (Richard Branker Research Model Solo D.Wave) were shipped to colleagues at the Secretariat for the Pacific Community (SPC) in Fiji, to be deployed on reefs through the Tuvalu Island Chain by SPC personnel. Over the course of several weeks the instruments were placed in transects on the fore-reef and reef-flat of 6 island atolls in Tuvalu, and left to record data on waves and water levels for a period of 87 days.

Process_Date: 20191008

Process_Step:

Process_Description:

Raw data from each instrument were exported to ASCII text files using the manufacturers software, RBR Ruskin v2.8.0, on an Apple Macintosh Personal Computer running OS10.11.6. Exported data were QA/QC’d and exported to netCDF in Matlab R2017a. During post-processing, data collected when instruments were out of the water, and data degraded by biological fouling, were removed from the time series. Bad data points were identified by 1) the deployment and recovery times, and 2) pressure readings equal to or less than 3 cm of water. The raw pressure readings include the pressure from both the overlying water and the atmosphere, and therefore have to be corrected to remove the atmospheric pressure. Data on atmospheric pressure were downloaded from a local weather station at the Funafuti Airport on the island of Tuvalu. The data on barometric pressure were interpolated to the burst interval of the pressure measurements, and a single value was removed from each burst.

Process_Description:

Files are named with a convention that uses a 13-digit alpha-numeric code. The first three characters for this dataset are all 'TVL' for the experiment name; the fourth and fifth positions represent the calendar year in which the first data point in the file was taken (19, 2019); the sixth, seventh and eighth characters are an alphanumeric code for the site name (NL1, NG1 etc.); the ninth and tenth characters represent the instrument position on the platform, where 01 is the top-most. Next is a two or three-character code for data type (rbr, RBR Wave). The suffix of ‘-b’ indicates that these are the raw burst data.
