Abstract

An integrated science data analytics platform (ISDAP) is an environment that enables the confluence of resources for scientific investigation. It harmonizes data, tools, and computational resources to enable the research community to focus on the investigation rather than spending time on security, data preparation, management, etc. OceanWorks is a National Aeronautics and Space Administration (NASA) technology integration project to establish a cloud-based integrated ocean science data analytics platform for managing ocean science research data at NASA’s Physical Oceanography Distributed Active Archive Center (PO.DAAC). The platform focuses on advancement and maturity by bringing together several NASA open-source, big data projects for parallel analytics, anomaly detection, in situ-to-satellite data matching, quality-screened data subsetting, search relevancy, and data discovery. Our communities are relying on data available through distributed data centers to conduct their research. In typical investigations, scientists would (1) search for data, (2) evaluate the relevance of that data, (3) download it, and (4) then apply algorithms to identify trends, anomalies, or other attributes of the data. Such a workflow cannot scale if the research involves a massive amount of data or multi-variate measurements. With the upcoming NASA Surface Water and Ocean Topography (SWOT) mission expected to produce over 20 petabytes (PB) of observational data during its three-year nominal mission, the volume of data will challenge all existing earth science data archival, distribution, and analysis paradigms. This paper discusses how OceanWorks enhances the analysis of physical ocean data where the computation is done on an elastic cloud platform next to the archive to deliver fast, web-accessible services for working with oceanographic measurements.
