An Environmental Assessment Of The Summer Plankton In The Vicinity Of The C.P. Crane Generating Station, George C. Grant, Stephen P. Berkowitz Jan 1979

An Environmental Assessment Of The Summer Plankton In The Vicinity Of The C.P. Crane Generating Station, George C. Grant, Stephen P. Berkowitz

Reports

A preliminary survey of summer plankton in ·waters surrounding the C. P. Crane generating station in Bengies, Maryland, revealed several possible effects of plant operation. These perturbations were separated into apparent small-scale and large-scale effects:

Small-scale effects were limited to the immediate discharge region of Saltpeter Creek and included (1) occasional elevation of temperatures at the surface (in August) to above the lethal limit for most zooplankton and sufficiently high to inhibit photosynthesis, (2) a decrease in chlorophyll-a, seen in July and August, (3) a sharp decrease in productivity, also in July and August, and (4) absence of a common …

Cereal, Pasture Legume And Water Supply Prospects At Forrestania : Results Of Experimental Work East Of Hyden, Western Australia, T E. Mcdowell, M G. Mason, J W. Gartrell, William J. Toms, I A F Laing Jan 1979

Technical Bulletins

The agricultural potential of the Forrestania area appears at least equal to that of much of the settled eastern wheatbelt. The scrubplain soils of the Forrestania area have an average yield potential of at least 1 000 kg/ha wheat and carrying capacity of 1.8 to 3.7 sheep per hectare on improved pastures. The use of clover ley rotations would maintain these levels of potential yield. Partial crop failures caused by adverse seasonal conditions could be expected 10 years in every 100.
