(2018). Hui O Ka Wai Ola Water Quality Data [Data set]. Zenodo. http://doi.org/10.5281/zenodo.1173717. The goal of the Hui O Ka Wai Ola (Association Of The Living Waters) citizen-science based water quality program is to increase the capacity for monitoring water quality in Maui (2016-) and Lanai (2023-) coastal waters by generating reliable data to assess long-term water-quality conditions and detect temporal trends. These data augment the data produced by the Hawaii Department of Health (DOH) Clean Water Branch (CWB) beach monitoring program. Data are collected and analyzed every two or three weeks for physical and chemical parameters, including ocean salinity, pH, temperature, organic nutrients (nitrogen and phosphorous compounds), dissolved oxygen (DO), and total suspended sediment (TSS). Some water samples are immediately tested at mobile labs while others are processed for testing at University of Hawaii and/or other labs. PacIOOS provides timely, reliable, and accurate ocean information to support a safe, clean, productive ocean and resilient coastal zone in the U.S. Pacific Islands region. The Pacific Islands Ocean Observing System (PacIOOS) is funded through the National Oceanic and Atmospheric Administration (NOAA) as a Regional Association within the U.S. Integrated Ocean Observing System (IOOS). PacIOOS is coordinated by the University of Hawaii School of Ocean and Earth Science and Technology (SOEST). Hui O Ka Wai Ola is a partnership between The Nature Conservancy (TNC) Hawaii, Maui Nui Marine Resource Council, and West Maui Ridge to Reef (R2R) Initiative and supported by NOAA Coral Reef Conservation Program, National Fish and Wildlife Foundation (NFWF), Lahainaluna High School, Maui County, and North Beach-West Maui Benefit Fund, Inc.
