| Summary: | On 15 February 1976 the USSR Research Ship PROFESSOR VIESE and the US R/V T.G. THOMPSON rendezvoused in the southern Drake Passage. The ships simultaneously occupied hydrographic stations as close together as feasible. Calibration standards for salinity, dissolved oxygen, and dissolved reactive phosphate and silicate were then exchanged by the two scientific parties. The calibration standards were found to be in very good agreement, the differences being insignificant with respect to measurement precision. The results of the hydrographic station intercomparison showed average differences with regard to sign between the two ships' results for temperature, salinity, dissolved oxygen, reactive phosphate, and reactive silicate to be realtively small but the root-mean-square differences to be quite large. This indicates that general comparisons of the two data sets are possible, whereas detailed considerations are not reasonable because of serious measurement errors aboard VIESE. |
