The influence of anthropogenic aerosols, in the form of ship exhaust effluent, on the microphysics and radiative properties of marine stratocumulus is studied using data gathered from the U.K. Met. Office C-130 and the University of Washington C-131A aircraft during the Monterey Area Ship Track (MAST) experiment in 1994. During...
Presents pesticide and herbicide application rates and recommendations, by tree growth stage, for pests that infect fruit trees. Covers apples, pears, and cherries. Provides (1) spray program for nutrients; (2) dilutions table for wettable powder and liquid products; (3) natural enemy impact guide for tree fruit pesticides; (4) illustrated bud...
Density estimation for marine mammal species is performed primarily using
visual distance sampling or capture-recapture. Minke whales in Hawaiian waters
are very difficult to sight; however, they produce a distinctive “boing” call, making
them ideal candidates for passive acoustic density estimation. We used an array of
14 bottom-mounted hydrophones, distributed...
Salmonid fish raised in hatcheries often have lower fitness (number of returning adult offspring) than wild fish when both spawn in the wild. Body size at release from hatcheries is positively correlated with survival at sea. So one explanation for reduced fitness is that hatcheries inadvertently select for trait values...

Studies of the effects of climate change on forests have focused on the ability of species to tolerate temperature and moisture changes and to disperse, but they have ignored the effects of disturbances caused by climate change (e.g., Ojima et al. 1991). Yet modeling studies indicate the importance of climate...

A new multi-telescope scanning Raman lidar designed to measure the water vapor mixing ratio for a complete diurnal cycle with high raw spatial (1.25 m) and temporal (1 s) resolutions is presented. The high resolution allows detailed measurements of the lower atmosphere and offers new opportunities for boundary layer research,...
Spectral attenuation and absorption coefficients of particulate matter and collocated hydrographic measurements were obtained in the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment. Within the bottom boundary layer (BBL) the magnitude of the beam attenuation decreased...
