Wave Data from CSIRO Waverider Buoys deployed in Tasmanian waters 1985-1993

In July 1985 the Division of Oceanography embarked on a wave observation program with the deployment of two "Waverider" buoys in the Southern Ocean near Cape Sorell on the west coast of Tasmania. Data were collected from moored Waverider Buoys deployed for various periods in Tasmanian coastal waters off Cape Grim, Cape Sorell (100m), Cape Sorell (50m) and Storm Bay. These observations are used to assess both typical and extreme sea states at these sites and for estimating spatial, seasonal and interannual variations in wave conditions in the Tasmanian region. The program concluded in December 1993 when the Storm Bay buoy ceased operation. There are two distinct datasets: a) Derived statistical data is available on-line for the seven locations mentioned in "Wave Climate Measurements in the Southern Ocean." b) Sample burst data for each of (possibly) nine locations. NOTES: All instruments used, and a copy of the data obtained during this program were sent to the Bureau of Meteorology. The Marine Observation Unit at the Bureau (marine_obs@bom.gov.au) may be able to provide additional information. The data files in this collection are not in a Datacente supported format and no assurances are given as to the accuracy of data, or of the locations implied by the data file names. The CSIRO Waverider program has not been continued.

Coastal marshes are highly dynamic and ecologically important ecosystems that are subject to pervasive and often harmful disturbances, including shoreline erosion. Shoreline erosion can result in an overall loss of coastal marsh, particularly in estuaries with moderate- or high-wave energy. Not only can waves be important physical drivers of shoreline change, they can also influence shore-proximal vertical accretion through sediment delivery. For these reason, estimates of wave energy can provide a quantitative measure of wave effects on marsh shorelines. Since wave energy is difficult to measure at all locations, scientists and managers often rely on hydrodynamic models to estimate wave properties at different locations. The Wave Exposure Model (WEMo) is a simple tool that uses linear wave theory to estimate wave energy characteristics for enclosed and semi-enclosed estuaries(Malhotra and Fonseca, 2007). The interpretation of hydrodynamic models is improved if model results can be validated against measured data. The data presented in this publication are input and validation data for modeled and observed mean wave height for two temporary oceanographic stations established by the U.S. Geological Survey (USGS) in the Grand Bay National Estuarine Research Reserve, Mississippi.
