Visual optics and ecomorphology of the growing shark eye: a comparison between deep and shallow water species [PDF]

Journal of Experimental Biology, 2009
SUMMARY Elasmobranch fishes utilise their vision as an important source of sensory information, and a range of visual adaptations have been shown to reflect the ecological diversity of this vertebrate group. This study investigates the hypotheses that visual optics can predict differences in habitat and behaviour and that visual optics ...

Airborne hyperspectral data to assess suspended particulate matter and aquatic vegetation in a shallow and turbid lake

, 2015
This paper presents an application of a physic-based method that relies on spectral inversion procedures to simultaneously estimate concentrations of water constituents, water column heights (cH) and benthic substrate types in Lake Trasimeno (Italy) from

Shallow optically active structural defect in wurtzite GaN epilayers grown on stepped 4H-SiC substrates [PDF]

, 2003
Shallow optically active structural defect in wurtzite GaN epilayers grown on stepped 4H-SiC substrates was investigated. The GaN epilayers grown with plasma-assisted molecular-beam epitaxy were optically characterized by photoluminescence and excitation

Modified Green's Functions for Shallow Water Acoustic Wave Propagation [PDF]

, 2004
This article presents an assessment of alternative forms of the Green’s function for boundary element simulations of acoustic wave propagation in shallow water. It is assumed that the problem is two-dimensional, the source of acoustic disturbance is time-

Assessment of Satellite-Derived Diffuse Attenuation Coefficients and Euphotic Depths in South Florida Coastal Waters

, 2013
Optical data collected in coastal waters off South Florida and in the Caribbean Sea between January 2009 and December 2010 were used to evaluate products derived with three bio-optical inversion algorithms applied to MODIS/Aqua, MODIS/Terra, and SeaWiFS ...

Synthetic Image Generation of Shallow Waters Using a Parallelized Hyperspectral Monte Carlo & Analytical Radiative Transfer Model [PDF]

, 2003
Modeled hyperspectral reflectance signatures just above the water surface are obtained from radiative transfer models to create synthetic images of the water surface.

Organic carbon pathways across the fluvial-marine transition zone of the Mackenzie River Delta – Beaufort Sea region and implications on ocean color remote sensing [PDF]

Biogeosciences
Arctic warming and hydrological intensification are accelerating permafrost thaw and increasing the export of terrestrial organic carbon (OC) and sediments from land via rivers and shallow coastal waters into marine waters, yet the fate of these ...

A transferable satellite-derived bathymetry model without site-specific calibration for Case-1 optically shallow waters using Sentinel-2/MSI imagery

GIScience & Remote Sensing
Accurate bathymetry in optically shallow waters (OSWs), particularly across coral reef environments, is essential for coastal ecosystem management and benthic habitat monitoring.
