Trophic state assessment of optically diverse lakes using Sentinel-3-derived trophic level index

open access: yesInternational Journal of Applied Earth Observation and Geoinformation, 2022
An accurate estimation of trophic state of lakes with satellite remote sensing is a challenge due to the optical complexity and variability associated with inland waters. Match-up data from 393 sampling stations that has concurrent Sentinel-3 OLCI images were acquired across Wuhan lakes.

Trophic levels of Tidal and Non-Tidal Marshes of Southern Mesopotamia

open access: yesMaǧallaẗ al-baṣraẗ al-ʻulūm al-zirāʻiyyaẗ, 2020
Carlson’s Trophic State Index (CTSI) was applied to assess the trophic status of two kind of southern Mesopotima marshes. Six stations were selected, three in non-tidal Chebiyesh marshes and other three in tidal East Hammer marsh.

A new trophic state index for assessing eutrophication of Laguna de Bay, Philippines

open access: yesEnvironmental Advances, 2023
For decades, Laguna de Bay has been affected by urban, industrial, and agricultural wastes resulting in nutrient-enrichment, decline in productivity and biodiversity loss, among other environmental problems. Eutrophication is a perennial problem of the lake that remains unabated.
