This report presents data collected on six cruises made during the months May-October 1972 along the Oregon coast. Both complete data listings and sequential surface data contour charts are presented. The latter graphically display rapid changes in surface water characteristics on time scales as short as a few hours.

During the summer of 1971, diurnal patterns of water status were monitored in Acer circinatum. Measurements of transpiration rate, internal moisture stress, and relative leaf resistance were used to characterize
the water status of the tree. For the days examined, the diurnal and seasonal
fluctuations of water status in relation...
Preliminary results of a comprehensive study of hydraulic fluctuations in Douglas-fir (Pseudotsuga menziesii) stems in response
to plant water status and environment are presented. Diurnal changes in stem circumference near DBH of a dominant Douglas-fir were monitored using automated band dendrometers. Measurements of transpiration rate, internal moisture stress and stomata...
