Climatological Statistics

These charts show some of the voyage climatological statistics from the time we spent in Antarctica, which have been calculated from 1-minute samples from the RV Tangaroa automatic weather station. They show wind speed, air temperature, sea surface temperature and atmospheric pressure histograms, the median, minimum and maximum values, and 2.5-th and 97.5-th percentiles.
