The first 25 years of the hydrology of the Onyx River, Wright Valley, Dry Valleys, Antarctica

This paper summarises the first 25 years of data on hydrological work carried out each summer on the Onyx River, Wright Valley, by summer teams of field hydrologists of the New Zealand Antarctic Research Programme. The assignment expanded from the single water-level recording weir site near Lake Vanda to a second site near the Wright Lower Glacier together with a number of tributary stream measurements that were installed as the programme progressed. This work was carried out together with Dry Valleys lake level and glacial measurements and is as of much historical as of scientific interest as it contains much inaugural Antarctic hydrology work.
