Correction of water column height variation on 2D grid high‑resolution seismic data using dGPS based methodology [PDF]

open access: yes, 2021
Variations in the physical properties of water column usually impede exact water column height correction on high-resolution seismic data, especially when the data are collected in shallow marine environments.

Large water-hammer pressure for column separation in pipelines [PDF]

open access: yes, 1991
Water-hammer pressures in a pipeline due to the collapse of a vapor cavity adjacent to a valve are investigated. A water-hammer event is initiated by the closure of a valve in a simple reservoir-pipeline-valve system.

Testing of the 4SM Method in the Gulf of California Suggests Field Data Are not Needed to Derive Satellite Bathymetry

open access: yesSensors, 2017
Satellite-derived bathymetry methods over coastal areas were developed to deliver basic and useful bathymetry information. However, the process is not straightforward, the main limitation being the need for field data.

The classification of submerged vegetation using hyperspectral MIVIS data

open access: yesAnnals of Geophysics, 2006
The aim of this research is to use hyperspectral MIVIS data to map the Posidonia oceanica prairies in a coastal lagoon (Stagnone di Marsala). It is approximately 12 km long and 2 km wide and is linked to the open sea by two shallow openings.

Akurasi Tematik Peta Substrat Dasar dari Citra Quickbird (Studi Kasus Gusung Karang Lebar, Kepulauan Seribu, Jakarta) (Thematic Accuracy of Bottom Substrate Map from Quickbrid Imagery (Case study: Gusung Karang Lebar, Kepulauan Seribu, Jakarta))

open access: yesIlmu Kelautan, 2012
Salah satu kelemahan metode koreksi kolom air adalah dapat memunculkan bias dalam estimasi rasio koefisien attenuasi. Bias ini berkontribusi pada nilai akurasi tematik peta substrat dasar.

Cloud optical thickness and liquid water path – does the k coefficient vary with droplet concentration? [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
Cloud radiative transfer calculations in general circulation models involve a link between cloud microphysical and optical properties. Indeed, the liquid water content expresses as a function of the mean volume droplet radius, while the light extinction ...
