Water Oscillation in an Open Tube

open access: yesInternational Scholastic Journal of Science, 2008
When an open tube is placed in a tank of water, covered on top, raised, and then uncovered, the water inside the tube will oscillate. The characteristics of the oscillation of the water inside the tube were studied.

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

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.

MAPPING CORAL REEF HABITAT WITH AND WITHOUT WATER COLUMN CORRECTION USING QUICKBIRD IMAGE [PDF]

open access: yes, 2010
Remote sensing from space offers an effective approach to solve the limitation of field sampling, in particular to monitor the reefs in remote sites. Moreover, using the achieved remotely sensed data, it is even possible to monitor the historic status of

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.

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 ...

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.

Towards the Combination of C2RCC Processors for Improving Water Quality Retrieval in Inland and Coastal Areas

open access: yesRemote Sensing, 2022
Sentinel-2 offers great potential for monitoring water quality in inland and coastal waters. However, atmospheric correction in these waters is challenging, and there is no standardized approach yet, but different methods coexist under constant ...

CUBESAT-DERIVED DETECTION OF SEAGRASSES USING PLANET IMAGERY FOLLOWING UNMIXING-BASED DENOISING: IS SMALL THE NEXT BIG? [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Seagrasses are one of the most productive and widespread yet threatened coastal ecosystems on Earth. Despite their importance, they are declining due to various threats, which are mainly anthropogenic.
