The Ocean Hypoxia Monitoring Project aims to study oxygen depletion in Jakarta Bay using real-time IoT buoys developed by BRIN and IPB University. This system measures dissolved oxygen at surface and bottom layers to identify hypoxic zones that can impact marine life and coastal ecosystems.
Although the current observation is based on a single buoy, the planned 2026 deployment will expand the monitoring network to multiple sites distributed across Jakarta Bay, representing nearshore-to-offshore environmental gradients.
Measurement of dissolved oxygen and temperature at depth in Jakarta Bay to detect potential hypoxia zones.
Monitoring oxygen and temperature near the surface to capture vertical stratification and water exchange dynamics.
