In 1960 a program of monitoring the zooplankton populations of Yaquina Bay, Oregon, was begun. The frequency of sampling was maintained at close to weekly intervals after 1 January 1963, usually at five stations. Abundances of all the species found in the bay of both meroplankton and holoplankton have been...
A test system was developed and used to
investigate ice/structure interaction with centrifugal
modeling. The test system was designed to perform two
main functions: (1) create a uniform ice sheet, and
(2) drive a model structure through the ice sheet at a
constant speed. Both of these functions were required...
The large lakes (Victoria, Albert, Kyoga, George, and Edward), covering 75% of Uganda’s surface area under contribute up to 90% of the capture based fisheries production. Until the late 2000s, the commercial fisheries in these lakes was largely based on species that grow to large sizes (> 20 cm) including;...
Covers soil basics such as soil formation, horizons, properties (including textural classes), profiles, site characteristics and evaluation, and the influences of soil characteristics on management decisions. Provides interpretation guides for permeability, water and wind erosion, drainage feasibility, irrigation suitability, most intensive crop, erosion control practice, and septic tank drainfields. Includes...

Measurements of the U₃₇ K’ index and the absolute abundance of alkenones in marine sediments are increasingly used in paleoceanographic research as proxies of past sea surface
temperature and haptophyte (mainly coccolith-bearing species) primary productivity, respectively. An
important aspect of these studies is to be able to compare reliably data...
