Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents several different applications of Doppler sonar measurements. Data were collected from four downward-slanting sonars operated on the Research Platform FLIP. The sonars provide profiles of backscattered intensity and slant velocity from approximately 100 m to 1000 m in depth with 20 m depth resolution. A technique to measure the vertically-acting Reynolds stresses, (u'w') ave and (v'w') ave, in the oceanic internal wave field using a multibeam Doppler sonar is presented. The stress measurement technique is applied to the Doppler velocity data collected during the experiment. The principal result is a lack of observed Reynolds stresses in the high vertical wavenumber, high frequency internal wave band which can be considered significantly different from zero, despite the use of a scale separation which is more restrictive than that of previous investigators, and the consideration of stresses on several different time scales. A characterization of the diurnal migration patterns of acoustic scattering layers based on the Doppler sonar measurements is presented. The effects of the diurnal migration of scatters are evident in both backscattered intensity and Doppler velocity, and two measurements provide complementary methods of analysis. The principal result is the observation of three distinct scattering layers whose patterns of vertical migration show a high degree of persistence in both space and time.

Book Synopsis Observations of Fine-scale Vertical Shear and Strain in the Upper Ocean by : Jeffrey Thomas Sherman
Download or read book Observations of Fine-scale Vertical Shear and Strain in the Upper Ocean written by Jeffrey Thomas Sherman and published by . This book was released on 1989 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis addresses the vertical wavenumber frequency (m, omega) distribution of vertical shear and strain in the upper ocean. Part of the data set includes measurements from a newly-developed pulse-to-pulse coherent sonar. Chap. 2 discusses its design and performance. Chap. 3 investigates the effects of zooplankton distribution on Doppler sonars which use small ensonified volumes. A secondary data set of isopycnal vertical displacement (eta) was collected with a profiling CTD system. Vertical shear (del w/del z, del v/del z) and vertical strain (del m/del z) data are analyzed in Chap. 4. Shear spectra; Vertical strain spectrum; Theses. (EDC).

Available in PDF, EPUB and Kindle. Book excerpt: The need for a volume dealing with the concept of indicator organisms became evident during a symposium on the subject, organized by the present editors for the Southern California Academy of Sciences. Ques tions were posed about the appropriate uses of indicator organisms and the "rules" governing the application of the indicator concept to particular problems. For example, how does one distinguish true indicators from biological anomalies? What kinds of organisms can appropriately be associated with conditions and events at various scales in time and space? To what extent does one species represent other species in the same environmental setting? Can the indicator concept be applied to the context of modern sampling and analytical technology? How can anthropogenic perturbations be distinguished from natural phenomena? How can unlike matrices from differing data bases with differing scales best be matched? Such questions are especially pertinent in today's research environment. The use of indicator organisms, while certainly not new, is the corner stone for much scientific research. In the past two decades, indicator organisms have played increasingly important roles in the development and implementation of public policy. In particular, indicator organisms are being used to describe local environments and natural or anthropogenic perturbations to them, although there are pitfalls and problems associated with those usages. A growing number of nonbiologists, including physical oceanographers, find indicator organisms helpful, and sometimes essential, to their re search.
