Developing a Generalizable Spectral Classifier for Rhodamine Detection in Aquatic Environments
Remote SensingIn environmental studies, rhodamine dyes are commonly used to trace water movements and pollutant dispersion. Remote sensing techniques offer a promising approach to detecting rhodamine and estimating its concentration, enhancing our understanding of ...

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform
Limnology and Oceanography: MethodsAbstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature ...

Sensors, 2017 All empirical water column correction methods have consistently been reported to require existing depth sounding data for the purpose of calibrating a simple depth retrieval model; they yield poor results over very bright or very dark bottoms.

Seasonal Variability of Chlorophyll in Lake Cuitzeo, México with Hyperspectral EnMAP Data [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesLake Cuitzeo, Mexico’s second-largest freshwater lake, is a highly eutrophic system with spatial and seasonal variability. Monitoring chlorophyll-a, a key indicator of phytoplankton biomass and trophic status, is essential for understanding its ...

IEEE Transactions on Geoscience and Remote Sensing, 2014 This paper outlines a methodology for the estimation of the environmental noise equivalent reflectance in aquatic remote sensing imagery using an object-based segmentation approach. Noise characteristics of remote sensing imagery directly influence the accuracy of estimated environmental variables and provide a framework for a range of sensitivity ...

ILMU KELAUTAN: Indonesian Journal of Marine SciencesTechnology to obtain bathymetric information has become necessary considering the length of the coastline and the many islands owned by Indonesia. Measurement technology using multi-beam and single-beam echo sounders is still an alternative to producing bathymetric information. In shallow water, using echo sounders has constraints and limitations, such

Remote Sensing of Optically Complex Waters - The Multivariate Approach
, 2005 Optically complex waters, often referred to as case-2 waters, are characterised by the fact that several optically active constituents are present in the water body where the individual concentrations may vary independently of each other. In addition the

An exploratory analysis of non-Poisson temporal behaviour in snapping shrimp noise [PDF]
, 2005 Snapping shrimp are a well known interference source for underwater sonar and communication systems, particularly in shallow and harbour waters. The noise produced by snapping shrimp is highly impulsive and the amplitude statistics are non-Gaussian ...
