Large scientific facilities are unique and complex infrastructures that have become fundamental instruments for enabling high quality, world-leading research tackling scientific problems at unprecedented scales. Cyberinfrastructure (CI) is an essential component of these facilities to provide the user community with access to data, data products, and services with the potential to transform data into knowledge. However, the timely evolution of the CI available at the large facilities is challenging and can result in science communities requirements not being fully satisfied. Furthermore, integrating CI across multiple facilities as part of a scientific workflow is hard, resulting in data silos.

In this paper, we explore how science gateways can provide improved user experience and services that may not be offered at the large facilities datacenter. Using a science gateway supported by the Science Gateway Community Institute that provides subscription-based delivery of streamed data and data products from the NSF Ocean Observatories Initiative (OOI), we propose a system that enables streaming-based capabilities and workflows using data from large facilities such as OOI in a scalable manner. We leverage data infrastructure building blocks such as the Virtual Data Collaboratory that provides data and computing capabilities in the continuum to efficiently and collaboratively integrate multiple data-centric CI, build data-driven workflows and connect large facilities data sources with NSF-funded CI such as XSEDE. We also introduce architectural solutions for running these workflows using dynamically provisioned federated CI.
