Discussion Points

Overview

-Monthly missions: monitor South Shore water quality focusing on the Ala Wai Canal outflow plume

-Event-focused missions: survey during significant rainfall events

-Salinity, Temperature, Backscatter, Chlorophyll, Current Velocity, Side scan vs latitude, longitude and depth

-Data products are available via the Kilo Nalu website (‘AUV surveys’)

South Shore Water Quality Monitoring

OverviewBaseline Ala Wai Canal Survey

ONR funded surveys

Test Survey

Ala Wai Research Group – Grieg Steward 24hr sampling

Salinity, Temperature, Backscatter, Chlorophyll

Overview

Event Surveys - Email Alert System

Program runs every hour, checks latest data from:

- Rain gages

- Stream flow gages

- Salinity + Temperature at NS01 and NS02.

Sends out warning message via email or text

Useful tool for us and for stakeholders (AWRG, Sea Engineering)
