Welcome: Data Exploration Tool

This dashboard visualizes the biogeochemical, physical, and aquacultural productivity data of the Nomilo fishpond, operated by Kauaʻi Sea Farm (KSF), to monitor its ecosystem and make informed management decisions aimed at restoring the fishpond and improving aquacultural productivity amid climate change. This fieldwork was performed as part of Research Question 2 of the Master thesis research.

In the interactive elements you can select parameters for each datasets. Positioning various parameters side-by-side can help visualize possible trends. For example, observe how increase of large phytoplankton count (Water Samples Data) only occurs after a change in wind direction (Weather Data). Explore yourself or read on about the results of the fieldwork below.

KSF Data

These data are simulated at four locations on the fishpond and at depths ranging between 0.5m and 7.5m. The locations involve: (1) Back Buoy, (2) Middle Buoy, (3) Production Dock, and (4) Auwai.

Summary of Key Insights from the Nomilo Fishpond Case Study

Problem Identified: Biogeochemical imbalances in water quality significantly hinder aquacultural productivity and overall ecosystem health in Hawaiian fishponds.

Research Focus: Investigate changes in biogeochemical and physical dynamics over time and space, and their effects on aquaculture growth and harvest.

Key Findings:
- Wind Shifts: A shift from north/northeast to western winds enhanced mixing dynamics in Nomilo fishpond, promoting water turnover.
- Deep-Water Dynamics: Benthic and deep-water conditions, along with groundwater levels, may be key in determining aquacultural productivity by pushing nutrients from deep sediments into the water column.
- Winter Productivity Drivers: Benthic and deep-water conditions, influenced by groundwater pushing nutrients from the anoxic 7.5m sediment into the water-column, significantly impact aquacultural productivity during winter.
- Aquaculture Benefits: Reversed mixing dynamics led to improved growth and survival rates of clams and oysters, linked to the increased availability of phytoplankton.

Implication: Demonstrates the critical link between environmental conditions and aquacultural productivity, underscoring the necessity for more comprehensive studies on fishpond ecosystems.
