As part of the Coastal Health Monitoring component of the Tuvalu IW R2R Project, baseline water quality surveys and analysis were carried from 14th to 17th September 2018. The coastal health monitoring program is designed to characterise ecological health of, and assess causal links between land based activities, and algal blooms and ciguatera occurrences in the Fogafale lagoon adjacent to populated areas of Funafuti atoll in Tuvalu. Baseline assessments of the Tafua pond, adjacent to the IW R2R demonstration dry-litter piggery site, was also conducted.
Based on section 102 and 103 of the Act that amends the Code of the Federated States of Micronesia, it describes the territorial sea as being established by twelve nautical miles' breadth. The inner boundary of the Territorial Sea of each island or atoll is the baseline. The outer boundary is a line, every point of which is twelve nautical miles seaward of the nearest point of the baseline.
