Cooperative marine fisheries research—the practice of involving the expertise of fishermen and scientists in conducting studies of ocean fishes—has increased gradually over the past 50 years on the US west coast. However, few studies have systematically collected and analyzed the experiences and perceptions of numerous cooperative marine fisheries research project...
The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...
An analysis was conducted to determine the effects of nonlinearity in
the one dimensional Navier-Stokes equation describing a viscous fluid flow.
An attempt was made to numerically determine the effect of temperature
variance on the fluid, either by varying the constant viscosity factor in the
energy dissipative term in the...
Firefighting is a very hazardous profession. Firefighters experience an injury rate that is three times higher than other physically demanding professions and the death rate in the fire service is also much higher compared to typical. Throughout the literature, data suggest the physical nature of firefighting contributes to the high...
Satellite ocean color data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) were used to examine distributions of chlorophyll concentration within the Southern Ocean for the period of October 1997 through September 1998. Over most of the Southern Ocean, mean chlorophyll concentrations remained quite low (<0.3-0.4 mg m¯³). Phytoplankton blooms where...
The location of the Antarctic Polar Front (PF) was mapped over a 7-year period (1987-1993) within images of satellite-deprived sea surface temperature. The mean path of the PF is strongly steered by the topographic features of the Southern Ocean. The topography places vorticity constraints on the dynamics of the PF...
A new instrument package for measuring physical (temperature, salinity, and depth) as well as optical (absorption and attenuation at nine wavelength) parameters using SCUBA is described. The package is attached to the SCUBA bottle and allows for sampling very close to the sediment–water and water–air interfaces. This package can also...
A new in situ fluorometer for the detection of oceanic photosynthetic pigment fluorescence is described.
Emission spectra from 546 to 733 nm are recorded for each of three different visible excitation bands ten
times a second. A Spectralon cell is used to improve the excitation coupling to and the collection...
The path of the Antarctic Polar Front (PF) is mapped using satellite sea surface temperature data from the NOAA/NASA Pathfinder program. The mean path and variability of the PF are strongly influenced by bathymetry. Meandering intensity is weaker where the bathymetry is steeply sloped and increases in areas where the...
