A series of intercalibration exercises were conducted to improve the ability to compare the results from different cruises. The first intercalibrations, on nutrient chemistry and primary production, were held in Hawaii starting on 3 September 1961. Dr. B.H. Ketchum (Woods Hole) led the nutrient intercalibration exercise and Prof. M.S. Doty (Univ. of Hawaii) led the primary production intercalibration. Other participants are shown on this circular.
