The influence of soil moisture stress and soil temperature on
transpiration has never been determined explicitly. This relationship
has been neglected mainly because of the lack of a satisfactory method
to control soil moisture stress.
A technique was developed to evaluate this relationship by
controlling soil moisture stress with osmotic...
The complexity of waste treatment presents a never ending
challenge to those in the field of design and operation. The tremendous
growth of this country has created serious waste treatment
problems, which pose a serious threat to our water resources and
our health.
A reflection of this growth is the...

A soil container 12 feet in diameter and 4 feet deep was constructed around the root ball of a 92-foot Douglas-fir tree in a naturally regenerated stand. The weighing mechanism, consisting of 550 feet of
2.5-inch butyl rubber tubing filled with water connected to a standpipe,
was placed under the...
Moored observations of currents and temperatures made in the upper 600 m on
eddy-resolving scales over a 2-year period are used to examine the spatial and temporal
characteristics of the California Current mesoscale circulation. The observations were
made at three principal longitudes: 124°W, 126°W, and 128°W in the vicinity of...
