<p> Millennial-scale variability in the Indian monsoon was temporally linked to changes in global ocean circulation during the last glacial period, as evidenced by planktic-benthic foraminiferal stable isotope and trace element results from an intermediate depth sediment core from the northwestern Bay of Bengal (Core NGHP-01-19B; 18&deg;58'N, 85&deg;39'E; 1,422 m). Paired planktic foraminiferal Mg/Ca and &delta;¹⁸O_c of <i> G. ruber</i> constrain sea surface temperatures and...

The current drive to find new low-carbon forms of electricity generation has intensified interest in capturing energy from ocean waves. The large range of devices currently proposed to fulfil this drive raises the question "What are the characteristics of an effective wave energy converter?". This thesis explores the design of a particular type of wave energy converter (WEC), namely the point absorber, by examining the properties and interactions of different types of surface waves. Current theo...

Helbig, Raymond Allan

Approved for public release, distribution is unlimited / Using the research platform 'FLIP', experiments were conducted to determine the effect of measured ocean surface roughness on transmission of sound from an airborne source into the sea. Signal noise both at the air-water interface and at points in the underwater sound field were recorded using modified AN/SSQ-57 sonobuoys. Ocean wave spectra and rms wave height, sigma, were determined from simultaneous recordings of ocean surface wave heig...

Approved for public release; distribution is unlimited. / The sound distribution everywhere within a wedge-shaped fluid overlying either a slow or a fast bottom was studied. Collecting all the results of the previous works in this area and overviewing them has been the primary purpose. All the cases reported earlier have been studied, and some new ones have been added. The variation of the transition point distance with the shore distance as a variable was observed. In addition, the isopressure ...

New approaches to the analysis of trace metal concentrations in seawater have the potential to advance the field of oceanography and provide a more comprehensive understanding of the marine biogeochemical cycles of trace metals and the processes regulating these cycles. Traditional oceanographic methods of trace metal analysis were developed several decades ago using benchtop liquid-liquid extraction (Danielson et al., 1978; Kinrade and Van Loon, 1974; Miller and Bruland, 1994; Moffett and Zika...

Sun, Cangjie

The statistical prediction of local sea surface winds at a number of locations over the global ocean (Northeast Pacific, Northwest Atlantic and Pacific, tropical Pacific and Atlantic) is investigated using a surface wind statistical downscaling model based on multiple linear regression. The predictands (mean and standard deviation of both vector wind components and wind speed) calculated from ocean buoy observations on daily, weekly and monthly temporal scales are regressed on upper level p...

Radiative forcing by increased atmospheric levels of greenhouse gases (GHGs) produced by human activities could lead to strongly undesirable effects on oceans and their dependent human systems in the coming centuries. Such dangerous anthropogenic interference with the climate system is a possibility the UN Framework Convention on Climate Change (UNFCCC) calls on nations to avoid. Unacceptable consequences of such interference could include inundation of coastal areas and low-lying islands by ris...

Snyder, Wallace Hutton.

This paper reports the results of field tests of Richardson's "four-thirds law" of horizontal diffusion, which relates the horizontal diffusion coefficients to particle separation, or eddy scale. A U. S. Navy photo-reconnaissance aircraft was used to gather data of diffusing patterns of rectangular paper sheets on the ocean surface and of current crosses nine feet below the surface. The data were gathered in Monterey Bay, California in water thirty- six fathoms deep in an area approximate...

Smith, Raymond C.

Approved for public release; distribution unlimited. / An investigation of the characteristics of wave groups occurring in five ocean swell trains was undertaken. To accomplish this, a definition of wave groups and their properties was developed. It was found that the average wave group period and the average maximum height in a group were essentially equal to the spectral period of maximum energy density and the significant height of a swell train, respectively. Additionally, the five sw...

It has been included in the digital archive for its historical value to NPS. Not believed to be a CIVINS (Civilian Institutions) title. / The need for a means of making ocean current observations that will be both rapid and economical is becoming critical. Contrary to what one might assume, there are many are...

Stouppe, David Edward

Approved for public release; distribution unlimited. / The knowledge of wave refraction is important in many studies. The rapid and relatively easy gaining of this knowledge is made possible by the use of the modern high-speed digital computer. Large numbers of spectral periods and incoming directions are easily investigated, and immediate results are obtained by use of the plot of the wave crest refraction from the computer. This program presents the wave crest refraction pattern of numer...

Collins, David A.

Approved for public release; distribution is unlimited / The development of an ambient noise model for use in ice-covered Arctic waters is the primary goal of this research. The generation of ambient noise is considered to originate from large scale deformation of the ice cover (pressure ridge formation) which is caused on a synoptic scale by convergence of the ice cover due to wind stress/speed associated with the passage of Arctic storms. The Arctic Storm Noise Model (ASNM) has been developed ...

Approved for public release; distribution is unlimited / Two assimilation experiments have been conducted using the Semtner/Chervin Parallel Ocean Climate Model at 1/40 resolution to investigate the dynamical changes which occur with the application of the nudging method to incorporate sea surface height observations (with associated vertical corrections to temperature and salinity) into a global eddy resolving ocean model. The first experiment used a previous model run as the observational fiel...

Approved for public release; distribution is unlimited / The problem of propagation of vertically polarized radiowaves in an inhomogeneous atmosphere and over rough ocean surfaces is solved using the parabolic equation method. The solution of the parabolic equation is accomplished through the use of the Fourier split-step algorithm. Formulation of the equations is based upon (1) recognizing that the Fourier kernels of the transform equations in the split step algorithm represent planes waves and...

Approved for public release; distribution unlimited. / The effects of ocean surface waves on optical signal fluctuations and optical refraction are evaluated. The effects on signal fluctuations were inferred from the ocean surface wave spectral density and temperature fluctuation spectral density. The effects of ocean waves on optical refraction are manifested in the near-surface gradient of the temperature profile. A modified temperature profile incorporating a statistical mixing length scale i...
