Abstract : Three weeks after the detonation of the Operation Wigwam weapon, a ship manned with personnel of the Scripps Institution embarked on a search for the patch of oceanic water contaminated by the weapon. After some adventure the water mass was found and surveye; it was larger and less active and was located differently than was anticipated. It was not economical to carry out the radiological survey of Operation Wigwam entirely on one cruise because (1) the range of activity to be measured was extreme, requiring a change of technique as the intensity decreased, and (2) personnel requirements changed after the first few days. The M/V BAIRD had been kept out of the hottest water so that it would be suitable for measuring low levels of contamination weeks after the detonation. This second cruise of the M/V BAIRD had such a different objective than had the first cruise of the group of Scripps Institution ships that it is being reported here with some completeness and with little reference to the findings of the first cruise. The latter data was delayed until long after the second cruise was completed in order that navigational records of the first cruise could be properly evaluated. (Author)
