Comparison of satellite-retrieved sea-surface temperatures with drifter and ship-borne measurements
Essen, Heinz-Hermann; Nacini, Elvio; Poulain, P. M. (NATO. SACLANTCEN, 1996/01)Sea-surface temperatures (SST) retrieved from satellite imagery are compared with in-situ measured data. The satellite data are from the Advanced Very High Resolution Radiometer (AVHRR) of the series of NOAA satellites, ... -
Deduction fo synthetic temperature profiles from SST observations in the Iceland-Faeroe frontal region
Warn-Varnas, Alex; Essen, Heinz-Hermann; Gezgin, E. (NATO. SACLANTCEN, 1996/01)Subsurface temperature and sound speed profiles are generated from satellite SST observations and -
Influence of internal waves on sound propagation in the SOFAR channel
Essen, Heinz-Hermann (NATO. SACLANTCEN, 1975/10)In this paper theoretical investigations due to the influence of internal waves to sound propagation in the SOFAR-channel are presented. The undisturbed acoustic field is described by a normal-mode model. The disturbance ... -
Ocean currents in the Iceland-Faeroe area, measured by a bottom-mounted ADCP
Essen, Heinz-Hermann (NATO. SACLANTCEN, 1992/12)Horizontal currents as a function of depth, measured by a bottommounted -
On the applicability of satellite-borne SAR imagery to coastal oceanography
Essen, Heinz-Hermann (NATO. SACLANTCEN, 1996/02)Synthetic aperture radar (SAR) images have been acquired from the first European Space Agency (ESA) remote sensing satellite ERS- 1. The mesoscale feature images are from Norwegian coastal waters and the Mediterranean (Elba ... -
On the predictability of subsurface sound speed from satellite-measured sea-surface temperature in the Mediterranean
Essen, Heinz-Hermann (NATO. SACLANTCEN, 1996/01)The report investigates the extent to which subsurface sound speed may be determined from satellitemeasured -
Perturbation theory applied to sound scattering from a rough sea-floor
Essen, Heinz-Hermann (NATO. SACLANTCEN, 1992/09)Perturbation theory is applied to acoustic scattering from a rough sedimental sea-floor. Realistic -
Scattering from a rough sedimental seafloor containing shear and layering, as determined by perturbation theory
Essen, Heinz-Hermann (NATO. SACLANTCEN, 1993/07)First-order perturbation theory is applied to reverberation from a rough sedimental seafloor. In addition to existing approaches, the seafloor is allowed to be shear-supporting or to be layered. Scattering strengths are ... -
Sea-surface winds in the Iceland-Faeroe area, as derived from the ERS-1 scatterometer
Essen, Heinz-Hermann (NATO. SACLANTCEN, 1994/04)This report presents measurements of surface meteorological data taken during three cruises of R/V Alliance to the Iceland-Faeroe frontal area during August 1991 (NORDIC'91), March 1992 (NORDIC'92a) and October 1992 ...
