ABSTRACT: Chlorophyll-a (Chl-a) concentration in lakes can tell a lot about a
lake’s water quality and ecosystem. It is a measure of the amount of algae
growing in a waterbody and can be used to monitor the trophic condition of a
waterbody. We studied the pre and post effects of marine ranch construction in
Chl-a concentration in Zhelin Bay, Southern China using Normalized Difference Chlorophyll Index (NDCI) and a web-based tool (https://mapcoordinates.info/). We used 8 day composite MODIS image collections of 500 m resolution and
randomly selected two stations to extract the chlorophyll-a concentration
values through the web-based tool. We recorded the slight increase in NDCI
values in all stations after the construction of marine ranch which is a good
indicator of the marine organisms’ reproduction and survival.
