A wide spectrum of maturing methods and tools, collectively characterized as the Semantic Web, is helping to vastly improve the
dissemination of scientific research. The OceanLink project, an NSF EarthCube Building Block, is utilizing semantic technologies to
integrate geoscience data repositories, library holdings, conference abstracts, and funded research awards. Provenance is a vital component
in meeting both the scientific and engineering requirements of OceanLink. Provenance plays a key role in justification and understanding when presenting users with results aggregated from multiple sources. In the engineering sense, provenance enables the identification of new data and the ability to determine which data sources to query. Additionally, OceanLink will leverage human and machine computation for crowdsourcing, text mining, and co-reference resolution. The results of these computations, and their associated provenance, will be folded back into the constituent systems to continually enhance precision and utility. We will touch on the various roles provenance is playing in OceanLink as well as present our use of the PROV Ontology and associated Ontology Design Patterns.
