COE project

29 Jan: Identifying hot spots of sewage pollution in Hilo, Hawaiʻi

PI: Tracy Wiegner
Hawaiʻi banned new cesspools in 2015, but groundwater contamination from the remaining 8700 cesspools in the Hilo area is a continuing concern. This work will use dye tracer studies to track cesspool outflows and use sewage indicators to establish contaminant sources to coastal groundwaters to inform future management decisions.

29 Jan: Microbial biogeochemical cycling across a chronosequence of mangrove introductions across Hawaiʻi

PI: Rosanna Alegado
Invasive mangroves harm Hawaiian coastal ecosystems, choking native plants, providing footholds for invasives, and generating leaf litter mounds inedible to Hawaiian species. This study investigates whether microbial communities can evolve to tackle the detritus and examines the resilience of our coastal ecosystems to mangrove invasion.

21 Jan: Envisioning In Situ Sea Level Rise Adaptation Strategies for a Densely Developed Coastal Community, Waikiki

PI: Wendy Meguro
Waikiki, an economic hub for Hawaiʻi, is already subject to regularly flooding and faces an uncertain future with sea-level rise. This project will offer conceptual design renderings towards an “in-place” adaptation strategy, to help motivate large-scale planning for an adaptive environment in this densely developed coastal community.

21 Jan: Effects of watershed restoration to traditional Hawaiian land use practices on health of nearshore coral reef ecosystems

PI: Robert Toonen
Reimplementation of traditional practices in the Heʻeia ahupuaʻa, in addition to invasive mangrove removal, has been predicted to support improvements to the coastal ecosystems of Kānoʻohe Bay. This study will examine effects on water quality and changes to coral reef health, in response to restoration efforts.
