White-tip reef sharks are common inhabitants of the shallow waters surrounding the Galapagos Islands, where several known aggregation sites have become touristic attractions. With the aim to describe site fidelity and residency patterns of the white-tip reef sharks in a saltwater creek, we used the ultrasonic telemetry method. The study was undertaken in a saltwater channel South of Academy Bay...

This study investigated the saltwater upconing mechanism in fractured coastal aquifers. Head-induced saline intrusion was initiated into three narrow sandbox aquifers containing individual horizontal discontinuities placed on different positions. Subsequently, using a peristaltic pump, freshwater abstracted from aquifers’ center, triggering upconing. Progressively larger pumping rates were appl...

Abstract The magneto-optical (transmittance, absorbance, and reflectance) characteristics of water saltwater in the presence a magnetic field (0T to 0.880T) are investigated this study. authors studies Raman spectra shift response fields. In case water, transmittance is high field, but saltwater, low at wavelength spectrum. was found be 0.7 percent higher 0.88T than absence 651nm–655.67nm. Simi...

To explore the spatial and temporal variations in salinity suspended-sediment concentration Danshuei River estuary of northern Taiwan, two intensive field surveys were conducted July 2016 2019 to assign high- low-flow conditions, respectively. According analysis tidal characteristics, duration during ebb tide was longer than that flood tide, while maximum discharge higher discharge, causing occ...

Factors driving freshwater salinization syndrome (FSS) influence the severity of impacts and chances for recovery. We hypothesize that spread FSS across ecosystems is a function interactions among five state factors: human activities, geology, flowpaths, climate, time. (1) Human activities drive pulsed or chronic inputs salt ions mobilization chemical contaminants. (2) Geology drives rates eros...
