An Improved Adaptive Multi-Scale Peak Detection Retracker for River Level Estimation Based on Sentinel-6 Fully Focused SAR Data

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(5), P. 791 - 791

Published: Feb. 24, 2025

Satellite altimetry technology has been widely used for the observation of oceans and inland water bodies. At present, fully focused synthetic aperture radar (FF-SAR) data, which significantly enhances along-track resolution, good prospects river level estimation. However, FF-SAR data with large volumes have more complex waveforms, brings challenges to waveform retracking. This study developed an improved adaptive multi-scale peak detection (ImpAMPD) retracker based on Sentinel-6 data. Initially, sub-waveforms are identified extracted from each waveform. Subsequently, segmented according number gates minimum gate length. Finally, retracking calculations performed determine levels. In this study, in situ six sections different features middle upper reaches Yangtze River were validate accuracy ImpAMPD perform a comparison three existing retrackers (OCOG, PTR, SAMOSA+). The results indicate that can utilize advantage high posting rate process multi-peak waveforms surface, accurately extract correct surface signals, achieve highly precise best obtained four sections, namely, Zhicheng, Shashi, Hankou, Huantan, STDDs 0.18 m, 0.26 0.47 0.36 respectively. is automated adaptable rivers varying widths, providing robust support monitoring flood management.

Eutrophication Conditions in Two High Mountain Lakes: The Influence of Climate Conditions and Environmental Pollution

Hydrology, Journal Year: 2025, Volume and Issue: 12(2), P. 32 - 32

Published: Feb. 13, 2025

The lakes known as El Sol and La Luna are high mountain water deposits located in Mexico within an inactive volcanic system. These of ecological importance because they unique Mexico. However, currently, the have experienced changes their shape increase algae blooms, coupled with degradation basin, which has alerted government entities to need address lakes’ problems. To environmental status Luna, a trophic study was conducted during period 2021–2023, including analysis influence climatic variables, lake quality, eutrophication conditions. state established based on index. Pearson correlations defined interrelation between distinct factors influencing status. registered higher conditions than Luna. identified seasonal eutrophic transitioning from oligotrophic mesotrophic, showing levels chlorophyll, total phosphorus, nitrogen low transparency. principal altering were pollution variables (precipitation ambient temperature). Eutrophication prime factor impacting perimeter loss at Sol, whereas it due decline precipitation.

Effects of Microorganisms in Fish Aquaculture from a Sustainable Approach: A Review

Microorganisms, Journal Year: 2025, Volume and Issue: 13(3), P. 485 - 485

Published: Feb. 21, 2025

Aquaculture is the fastest-growing food production sector. However, it faces significant challenges, including demand from a growing global population, which estimated to reach 10.4 billion by year 2100, disease outbreaks, environmental impacts, and overuse of antibiotics. To address these issues, sustainable alternatives such as use microorganisms (probiotics, bacteriophages, genetically modified microorganisms) have gained attention. This review examines effects on fish aquaculture, focusing their potential improve growth, health, resistance while reducing impacts. Probiotics, particularly lactic acid bacteria yeasts, been shown enhance immune responses, digestive enzyme activity, nutrient absorption in fish. Bacteriophages offer promising alternative antibiotics for controlling bacterial pathogens, with studies demonstrating efficacy mortality rates infected Additionally, (GMMs) explored ability produce beneficial compounds, enzymes antimicrobial peptides, can health reduce need chemical treatments. Despite potential, challenges regulatory hurdles, public acceptance, risks must be addressed. highlights importance further research optimize aquaculture underscores role promoting practices. By integrating biological tools, industry move towards more environmentally friendly future.
