This nearshore sensor (nss_cwb_004) operated for a year between September 7, 2021 and September 10, 2022. It was located separately at two locations within Keʻehi Lagoon near Keʻehi Lagoon Beach Park and the Interstate H-1 freeway on the South Shore of Oʻahu in the State of Hawaiʻi. The sensor package was mounted to a PVC mooring at approximately 2.5 meters depth. Data were collected every 6 minutes. The CWB collected these data to assess water quality in the lagoon to determine whether state water quality standards are being met and to monitor how the water quality is changing over time. Due to the triangle shape of the boat canal and multiple islands within the lagoon, water circulation is limited, in particular in the vicinity of the stream mouths.
nss_cwb_004 was owned by the State of Hawaiʻi Department of Health Clean Water Branch. PacIOOS maintained the nearshore sensor under the supervision of Dr. Margaret McManus and lab, and enables easy access to the data.
