Monitoring Water Quality at Ma‘alaea Harbor, Maui


Monitoring Water Quality at Ma‘alaea Harbor, Maui

As part of the PacIOOS Water Quality Sensor Partnership Program (WQSPP), the Maui Nui Marine Resource Council (MNMRC) deployed a nearshore sensor at Maʻalaea Harbor, Maui. The non-profit organization is interested to learn more about the effects of tides, wind, and swell on water quality in the harbor, and monitor water quality variability over time. The data will help inform the watershed management plan Vision for Pohakea, which aims to reduce sediment and pollutants in Maʻalaea Bay and its harbor. MNMRC is also partnering with the Waterkeepers Hawaiian Islands to utilize several thousand oysters in the harbor to help improve water quality.

PacIOOS’ nearshore sensor will be rotating to various locations within the harbor, collecting data on water temperature, salinity, turbidity, chlorophyll-a, and depth.
