🌏 Kalauhaʻihaʻi & Kānewai from Above
🌺 Project Overview
Aloha, Welcome to our pilot data dashboard!
This project is a collaboration with
Maunalua Fishpond Heritage Center.
Since 2021, Chaminade students in Professor
Lupita Ruiz-Jones’s environmental science classes have explored Kalauha’iha’i and Kānewai to study the impact of the vital flow of water mauka to makai.
This research focuses on tracking water temperature, oxygen levels, salinity, pH, and water level changes.
At Kalauha’iha’i, data collected before and after lava tube restoration helps assess the impact of increased freshwater input and connectivity to the ocean. Comparing this with Kānewai offers insights into how continuous freshwater flow shapes these ecosystems.
This pilot dashboard features graphs of temperature, pH, and dissolved oxygen for both sites. We’ll keep updating it with data from 2021 to the present, adding the other variables we have been measuring—and we welcome your feedback to help us improve!

A few notes about the data
- Onset sensors and data loggers record every 10 min continuously when deployed.
- Sensors are calibrated following the manufacturer’s guidelines.
- We continue to collect data and will continue to add it to the dashboard.
- Student research interns have presented results from this project at the Hawai’i Conservation Conference 2023, 2024, and 2025.
| Variable | Date we started to collect data |
|---|---|
| Temperature | 2021 |
| pH | 2022 |
| Dissolved Oxygen | 2022 |
| Conductivity (Salinity) | 2022 |
| Water Level Change | 2023 |
Funding
Student research interns have been supported through the following funding sources: NSF Alliance Supporting Pacific through Computation Excellence (All-SPICE) and NSF Louis Stokes Alliances for Minority Participation (LSAMP).
