The principal salinity extrema and extremum surfaces of the
world ocean are described by the analysis and plotting of data from
885 hydrographic stations in the three major oceans, the Southern
Ocean, and the American Mediterranean Sea. The distributions of
salinity, temperature, depth, and density along the extremum surfaces,
plotted...
Objectives of this study were to determine differences in
herbage production of three seral stages of three habitat-types.
Field studies were conducted in 1967 and 1968 on the Squaw Butte
Experimental Range.
Twelve, 400-square-foot, paired exclosures were established
in each habitat-type. Herbage was clipped from four, 48-squarefoot
samples in one...
Clatsop Beaches, characterized by flat beach-face slope (1:70) and small sandsize (0.2 mm.), have supported commercial and recreational fisheries for the razor clam (Siliqua patula) for many years. Tracing the linear growth of two year classes through more than one year following set led to a validation of the ring...
