Analysis of Algae Concentration in the Lagos Lagoon Using Eye on Water and Algae Estimator Mobile App

Abstract

Concentrations of chlorophyll and algae in the Lagos lagoon needs to be studied in order to get information on water properties such as water color which indicates life, sediments and dissolved organic matter with the help of eye on water mobile application. Also, information from the study of algae chlorophyll concentrations produces results on amount of chlorophyll a concentration in a body of water and predicts if there will be a likely occurrence of harmful algal bloom (HABs). The HABs issue is a condition when algae in aquatic system rapidly increases in density leading to high production of toxins that give out unappealing odors, shoreline scums and kill fishes. The mobile application is used to estimate algae concentration. The results show the water color of Lagos lagoon is greenish-brown which translates to high nutrients and phytoplankton (food) for aquatic life present and also Makoko possess higher amount of chlorophyll concentration than the other two areas (University of Lagos Waterfront and Ilaje-Bariga from which samples were gotten) reason why Makoko is a major fishing ground and why their locals are engaged in the primary activity. Based on the study conducted on algae chlorophyll concentrations it can be deduced that the Lagos Lagoon which is greenish brown in color, rich in nutrients and phytoplankton possesses moderate amounts of chlorophyll concentrations required to favor aquatic life. In addition, harmful algal blooms (HABs) does not occur, however precautionary measures to be taken if this is so are recommended in this research.
