Nondimensionalized equations of motion for waterdrops, not necessarily obeying Stokes's
law, are derived and used to calculate the response of various size drops to changes in horizontal
wind speed. We find that (1) cloud drops respond almost instantaneously to changes
in wind speed, whereas raindrops require considerable time to adjust,...
The tachinid species Ormia Dominicana, Ormia lineifrons, and Sitophaga aurigera were observed to aggregate atop 2 towers in central Florida shortly after sunset. The activity period for each species was brief, and that of 0. dominicana was temporally separated from that of S. aurigera. Aggregations occasionally exceeded 100 individuals of...
The existence of a distinct coastal zone is confirmed in Lake Tahoe (California-Nevada) by horizontal transects measuring chlorophyll and temperature simultaneously. Creation of the coastal region is influenced by bottom topography, the nature of the surface wind stress, and the difference between physical processes occurring within a Rossby radius of...
Field measurements of onshore and longshore velocities in the surf zone have been obtained on Martinique
Beach, Nova Scotia, for the purpose of investigating the dynamics of the infragravity band (0.003-
0.03 Hz) of the spectra. A total of35 data runs were obtained during a 1-week period. Of particular interest...
This review documents the advances in our knowledge of the oceanic internal wave field during the past quadrennium. Emphasis is placed on studies that deal most directly with the measurement and modeling of internal waves as they exist in the ocean. Progress has come by realizing that specific physical processes...
In a recent paper, Sandwell and Agreen [1984; hereafter SA]
presented figures of global seasonal wind speed and sea state
as measured by the GEOS 3 satellite altimeter. Since that
time, Chelton and McCabe [1985; hereafter CM] have found
that problems exist in the algorithms used to retrieve wind
speed...
The interaction of basalt melt with mantle harzburgite at low pressure might result in silica enrichment of the melt by assimilation of orthopyroxene. Experimental tests of this hypothesis show that silica-rich liquids (56 wt %) are produced by melt-orthopyroxene reaction at 1200° to 1250°C. These silica-rich liquids are enriched in...
Ingestion and respiration by Metridia pacifica, the dominant large copepod during autumn and winter in the subarctic Pacific, were investigated by shipboard and laboratory experiments. Diel variation in the rate of grazing on phytoplankton by M. pacifica was determined from measurements of gut pigment content and gastric evacuation rate. Both...
