Deep Blue Analysis

The accuracy of a wave model forecast can be critical when it is used to make operational decisions. If the forecast five days out shows acceptable conditions – workable wave heights and wind speeds – and a decision is made to stay in the field, then it is inconvenient, costly, and potentially dangerous when the actual wave heights and wind speeds are much higher. More importantly it biases the opinions of your offshore managers in using a forecast they do not view as reliable. So, what is a quantifiable measure of how accurate a wave model is? We use the real-time data from NDBC wave buoys – wave heights, wave periods, wave directions, wind speed and wind direction – to validate the accuracy of a wave model’s ability to forecast the sea state.

Learn about an improved method of measuring a current profile that eliminates the unknown of knowing where the ADCP package is in the ocean while it is lowered and recovered. I have used this improved technique on eleven campaigns that took 44 profiles.
