We present the water science gateway developed at the University of Hawaii (UH), called the Ike Wai Gateway, Ike meaning knowledge and Wai meaning water in Hawaiian. The gateway supports research in hydrology and water management by providing tools to address questions of water sustainability in Hawaii. The gateway provides centralized web-based user interfaces and APIs supporting multi-domain data management, computation, analysis and visualization tools to support reproducible science, modeling, data discovery and decision support for the Hawaii EPSCoR Ike Wai research team and wider Hawaii hydrology community. By leveraging the Agave platform UH has constructed a gateway that ties data and advanced computing resources together to support diverse research domains including microbiology, geochemistry, geophysics, economics and humanities, coupled with computational and modeling workflows delivered in a user-friendly web interface and REST APIs. Current features include data/metadata management and sharing, computational job execution/management, jupyter notebook integrations, and containerized computing. These capabilities form the basis for an extend-able API base that will be leveraged to tie in additional components and decision support applications as the Ike Wai project continues to progress.
