Methods being studied are as follows: the thermodynamic method based on water potential and thermocouple psychrometers; the tracer method using atmospheric tritium; the annual water balance based on the annual heat balance; the field lysimeter using thermocouple psychrometers; the influence of soil breathing as a result of changes in barometric pressure; and the influence of soil stratification. Progress to date has involved the installation of thermocouple psychrometers from the surface to the water table 310 feet below. These instruments are in the process of equilibration. Isothermal methods of analyzing water potential must be extended to include nonisothermal conditions which are dominant at the Hanford Reservation. Tracer techniques using tritium analyses of soil samples have successfully demonstrated that archaic water exists in virgin soil at the Hanford Reservation from a depth of approximately 7 meters to the water table, indicating that percolation has been limited to lesser depths. The annual heat balance indicates that quantities of water many times greater than the annual average precipitation of 16 centimeters can be evaporated from the soils at the Hanford Reservation during a normal summer. This indicates that the critical precipitation (P/sub c/) value may be greater than 30 to 50 centimeters of water. …

This report discusses the controversy over fishing rights between the United States and three South American nations (Chile, Peru, and Ecuador) which culminated in the seizure of U.S. tuna fishing vessels by Peru and Ecuador in waters the U.S. considered outside their territorial jurisdiction. The main events of the controversy, diplomatic actions taken by the nations involved, and policy options are discussed.

We propose an investigation of neutrino interactions in the deuterium filled 15-foot bubble chamber at NAL. A 250,000 picture run with 200 GeV protons should yield very interesting physics even with a 'bare' deuterium chamber. This addendum extends the physics discussion in the original proposal to the search for charm particles, and the study of neutral currents. A ({nu}{sub {mu}},d) bubble chamber exposure with E{sub P} = 200-300 GeV is the most promising experiment that can be done to search for the type of charm particles that are essential to Gauge theories of weak and electromagnetic interactions. This addendum updates and summarizes Proposal 151. We propose a 300,000 picture run of the 15-foot bubble chamber filled with deuterium exposed to a wide band, 2 horn, neutrino beam from protons of energy E{sub p} {ge} 300 GeV. The analysis will be based primarily on the bare bubble chamber data but will also use the EMI wherever useful. The physics purposes of the experiment include: (1) Extensive search for charmed baryons and mesons; Determination of the ratio of the total charged current cross sections {sigma}({nu},n)/{sigma}({nu},0); (3) Determination of d{sup 2}{sigma}{sup C.C.}/dxdy for ({nu},n) and ({nu},p) interactions separately; (4) Study of ({nu},n) and …
