The expedition took place in January and February 1954.[3][4][5] The vessel used to undertake this expedition was the MV Alert.[3] The Alert, which had been used for other scientific expeditions,[6] was specially fitted out for this expedition with dredging and trawling equipment, a winch and specially designed sorting benches.[7]
On its way to the Chathams the expedition did oceanographic work on the Mernoo Bank on the Chatham Rise, the area of sea bed between Banks Peninsula and the Chatham Islands.[2] They visited a number of locations on Rekohu (the main island) including Owenga, Kaingaroa, Waitangi, Petre Bay, Te Whanga Lagoon and Port Hutt.[3] Scientists also landed on the smaller islands of South East (Rangatira) Island, Pitt Island, The Sisters and the Forty-Fours.[1][3]
The expedition collected thousands of specimens of both land and marine fauna including over 150 new species.[1][3][6] Over 1200 specimens from the expedition are held by Te Papa.[5] Photographs taken by Dawson are held in the Alexander Turnbull Library.[8]
