Data are reported from regular, twice or three times weekly, sampling of atmospheric HTO and HT at stations in Miami, FL; Mauna Loa, HI; Fairbanks, AK; and Baring Head, N.Z. In addition, sampling has begun in Miami also for tritium bound in lower hydrocarbons, here called CH/sub 3/T. In December 1974--January 1975, and again in January--February 1976, sampling was performed on board a ship en route from California to McMurdo (Antarctic). The data show a gentle, slight dilution of HT southwards from about 52 at/mg at 36/sup 0/N to about 40 at/mg in New Zealand and south. During the period of this Data Report, the laboratory also participated in Project Airstream. Five series of stratospheric sampling flights were made, the programmed area of coverage of each was from 10/sup 0/S latitude to 75/sup 0/N latitude, and altitudes between 12 km and 19 km. The data are not included in this report, but will be published at an early date. In cooperation with the International Atomic Energy Agency (IAEA)/World Meteorological Organization Isotopes-in-Precipitation Network, monthly composite rain samples were measured for Miami, Barbados, and Western Samoa.
