Riverine plumes in nearshore coastal waters are areas of enhanced production and accumulation of prey and may increase availability of food during a critical period of juvenile salmon survival and hence serve as a nursery area for these juveniles. Physical and biological sampling was conducted along a cross-shelf transect through...
Northern highbush blueberry (Vaccinium corymbosum) is well adapted to acidic soils with low nutrient availability, but often requires regular applications of nitrogen (N) and other nutrients for profitable production. Typically, nutrients accumulate in the plant tissues following the same pattern as dry matter and are lost or removed by leaf...
Raspberry and blackberry (Rubus sp.) plantings have a relatively low nutrient requirement compared with many other perennial fruit crops. Knowledge of annual accumulation of nutrients and periods of rapid uptake allows for better management of fertilization programs. Annual total nitrogen (N) accumulation in the aboveground plant ranged from 62 to...
The present work characterizes the time-space scales of variability and forcing dependencies of a unique 26 year record of daily to hourly shoreline data from a steep beach at Duck, North Carolina. Shoreline positions over a 1500 m alongshore span were estimated using a new algorithm called ASLIM based on...
Seasonal Affective Disorder (SAD) is a mood disorder that is characterized by depressive symptoms that onset and remit at the same times each year. Whereas few people (about 1%) experience problems severe enough to be labeled SAD, many people (estimates range from 30%-90%) may experience mild to moderate changes in...
Seasonality is defined as a change in mood and behavior with the seasons. Research shows there is a possible connection between vitamin D levels and mood (Murphy & Wagner, 2008; Lansdowne & Provost, 1998). Given that vitamin D is produced when skin is exposed to sunlight and varies with sun...

The alteration of subseafloor volcanic glass from three locations is qualitatively attributed to biological
(biotic) or chemical (abiotic) reactions on the basis of microscopic morphology of the boundary between
the unaltered and altered glass. Eleven-element composition of fresh basalt glass (sideromelane) and its
alteration products were determined by electron microprobe....
The spatial and temporal variability of nearshore sand bar morphology is quantified using a unique data set
spanning 2 years. The data consist of daily time exposure images of incident wave breaking on an open coast
sandy beach which may be used to infer bar morphology (Lippmann and Holman, 1989)....
