This work introduces a new approach for modelling sea surface current from AVISO/Altimeter satellite data. This is based on utilizing of the Volterra series expansion in order to transform the time series of Merged Sea Level Anomaly satellite altimetry data into a real ocean surface current. The basic equation of hydrodynamic has been solved by first order Volterra model. Then, the Volterra ker...

On synthetic aperture radar (SAR) images acquired over the ocean often sea surface signatures of atmospheric gravity waves (AGWs) as well as of oceanic internal waves are visible. They often look quite similar and it is not always easy to decide whether the wave-like patterns result from AGWs or from oceanic internal waves. In this paper we present criteria how to discriminate between these two...

In this paper, the main goal is to reduce the heave motion between a surface effect ship (SES) and a wind turbine in order to safely transfer equipment and person to SES. For this purpose, an LQR control system is designed to damp the vertical motion of the surface effect ship in critical sea states including high-frequency and high amplitude regular waves as well as high frequency irregular wa...

The focus of this study is the assessment of the main range and geophysical corrections needed to derive accurate sea level time series from satellite altimetry in the Indonesia seas, the ultimate aim being the determination of sea level trend for this region. Due to its island nature, this is an area of large complexity for altimetric studies, a true laboratory for coastal altimetry. For this ...

In connection with a study of the extreme weather events over the North American continent in '" January, 1977, analyses were performed to investigate characteristic properties of spatial and temporal variation of sea surface temperature for the years of 1976 and 1977, using world distribution of sea surface temperature described in the accompanying paper, part 1. The time evolution of ocean te...

This paper is concerned with the real-time observation system of optical devices for recording of sea waves characteristics in wide range of wavelength from centimeters to hundreds meter. The energy spectra of short waves are obtained in real time by spectral analysis of sea surface image [1] with spectral analyzer operating under no coherent light. The spectral-kinematics characteristics of lo...

During the first 4 years of the SeaWiFS mission (September 1997 through August 2001), the spring blooms in the Slope Sea increased in magnitude. During the same time, the mean path of the Gulf Stream shifted northward. The northward trend of the Gulf Stream is evidenced in satellite sea-surface temperature imagery as well as in situ temperature, salinity, and current vector information collecte...

In order to investigate the electromagnetic (EM) scattering characteristics of the three dimensional sea surface contaminated by oil, a rigorous numerical method multilevel fast multipole algorithm (MLFMA) is developed to preciously calculate the electromagnetic backscatter from the two-layered oil contaminated sea surface. Illumination window and resistive window are combined together to depre...

The modulation of air-sea heat fluxes by geostrophic eddies due to the stirring of temperature at the sea surface is discussed and quantified. It is argued that the damping of eddy temperature variance by such air-sea fluxes enhances the dissipation of surface temperature fields. Depending on the timescale of damping relative to that of the eddying motions, surface eddy diffusivities can be sig...
