Field and laboratory work was undertaken in 1993 to increase understanding of the life history and ecology of the brown jellyfish,
Chrysaora fuscescens, a large semaeostome typically abundant in the neritic regions of the Oregon coast during summer months. Few
medusae were found during 1993, possibly the result of anomalous...
The problem addressed is absence of a class of objects in a finite set of objects, which
is investigated by considering absence of a species and absence in relation to a threshold.
Regarding absence of a species, we demonstrate that the assessed probability of absence
of the class of objects...
The potential gains that could be realized from
optimizing timber harvesting are significant. To a great
extent it is these initial functions that dictate the
quality of future manufacturing steps. Timber harvesting
systems are defined by the operations they contain and the
equipment that perform them. For any given harvesting...
The Coordinated Eastern Arctic Experiment (CEAREX) was a multi-platform geophysical study covering the period from winter 1988 to spring 1989 in the vicinity of the Yermak Plateau and Fram Strait. The Oceanography ("0") Camp component of CEAREX was designed to study the physical oceanographic conditions from the deep Nansen Basin...
Small-scale turbulence is a random phenomenon, and theoretical relationships about turbulent processes are often only crude approximations. There are relatively few accurate statements that can be made about a turbulent flow without recourse to experimental evidence from flow itself (Tennekes and Lumley, 1972). In the atmosphere, turbulent flows are relatively...
We describe a disease syndrome that afflicts larval, landlocked Atlantic salmon Salmo salar from Cayuga Lake, one of central New York's Finger Lakes. Mortality associated with the “Cayuga syndrome” is 98–100%. Death usually occurs between 650 and 850 centigrade degree-days after fertilization, approximately 2–4 weeks before yolk resorption is complete....
