This proposal by the Coniferous Forest Biome investigators requests support
for the third and fourth years of a highly integrated series of investigations
within the Ecosystem Analysis program of the United States effort under the
International Biological Program. The program for the Coniferous Forest Biome
has been approved by the...

"The information in this paper on litterfall in stands of red alder (Alnus rubra Bong.) was developed from a series of studies carried out to determine the pattern and quantities of litterfall of various
tree species grown at the University of Washington Charles Lathrop Pack Forest in western Washington. This...
Variation in nutrient content of forest trees is discussed using the
data from literature plus data collected by the authors. Sections are
included on sampling and methods of expression of nutrient content. The
emphasis is on possible causes of variation, which involves nutrient
variation between years, within the year, and...
In this dissertation, a new computational method for equality constrained nonlinear programming is developed. Specifically, problems of minimizing a nonlinear objective function f(x) subject to constraints h(x) = 0, where f is a scalar valued, x is an n-vector and h is a m-vector with m < n is considered....
We present a new hypothesis to explain the millennial-scale temperature variability recorded in ice cores known as Dansgaard-Oeschger (DO) cycles. We propose that an ice shelf acted in concert with sea ice to set the slow and fast timescales of the DO cycle, respectively. The abrupt warming at the onset...
A three‐dimensional primitive‐equation model for application to the nearshore surf zone has been developed. This model, an extension of the Princeton Ocean Model (POM), predicts the wave‐averaged circulation forced by breaking waves. All of the features of the original POM are retained in the extended model so that applications can...
The history of entomopathogenic nematology is briefly reviewed. Topic selections include early descriptions of members
of Steinernema and Heterorhabditis, how only morphology was originally used to distinguish between the species; descriptions of the
symbiotic bacteria and elucidating their role in the nematode- insect complex, including antibiotic properties, phase variants, and...
A new apparatus is presented that is capable of applying a constant fluid pressure at inflow and outflow boundaries. The apparatus can be refilled during operation and does not rely on an overflow mechanism. The device is constructed of two vessels, one that contains the delivered fluid and the other...
During boreal summer and fall, there is a strong southerly boundary layer flow across the equator into the east Pacific intertropical convergence zone (ITCZ). The modulation of this flow on synoptic to seasonal time scales is studied using an index of meridional pressure difference between the equator and the ITCZ...
Using a large eddy simulation (LES), the atmospheric boundary layer (ABL) is numerically modeled along 95°W from 8°S to 4°N during boreal autumn, and compared to observations from the East Pacific Investigation of Climate Processes in the Coupled Ocean–Atmosphere System (EPIC) 2001. Since the local ABL winds are predominantly southerly...
