The Hawaii Ocean Time-series project involves cruises to Station ALOHA nearly every month, starting in October 1988. Most of these cruises have been on ships equipped with acoustic Doppler current profilers, the observations from which are presented here. Continuous time series of currents at ALOHA are available elsewhere from the WHOTS mooring.
Funding from the National Science Foundation via grants OCE-0752606, OCE-0926766, OCE-1260164, and OCE-1756517, is gratefully acknowledged.
For each cruise, the processed shipboard ADCP data and a corresponding estimate of the barotropic tide are provided as netcdf files, individually and aggregated by cruise and by year. For more information, follow this link.
