|Access to and quality assessment of routine underway data collected by all oceanographic research vessels is a challenge for todays oceanographer. The multi-institutional R2R (Rolling Deck to Repository) project was recently funded by NSF to solve this problem. The WHOI Ocean Informatics Working Group helped to gain funding for this effort and plans to continue supporting it over the next 5 years. A common website dedicated to oceanographic data collected by all UNOLS research vessels can play a vital role in coordinating cruise-related raw data and data products.|
R2R is developing the infrastructure to support a central website (http://rvdata.us/) where oceanographers can find an index of and access the data sets collected by UNOLS, Coast Guard, and NOAA research vessels. WHOI, Lamont Doherty Earth Observatory, Scripps Institute of Oceanography, and Florida State University are partners in this effort. This project has started by focusing on access to all underway data collected by a research cruise and making it accessible as soon as an expedition is complete. Over the 5-year project lifetime, the team will address contributing collected data sets to national archives, such as NODC and NGDC, the &nbs
p;development of a science event-logger, evaluation of quality assessment and provenance, including certification of the degree of Q/A for a data set, and will provide ways to enable near-real-time feedback to shipboard technicians about the quality of the data being collected during the cruise.
Andrew Maffei, a member of the Ocean Informatics Working Group, is the lead PI for the WHOI part of the R2R effort. In addition to the primary goal of populating the site with cruise data distributions, WHOI's focus is to develop a science event logging standard format and provide a science event logging web application. As part of the larger Ocean Informatics Working Group focus, the data available through the R2R project will be used in pilot studies to better understanding of linkages between data sets as well as a platform to study and better understand relations between data provenance (history of data and metadata handling), Quality Assurance (Q/A) and the building of trust in unknown data used by researchers who did not collect the original data.
The primary objectives in the Ocean Informatics Working Group involvement are to (1) assist in the identification/design of a controlled vocabulary or ontology for time that supports the development of the science event-logger and (2) work with the R2R partners to consider the value of development of an ontology, or common metadata vocabulary, that supports links between research cruise-related data and data products located on websites and other data repositories.
WHOI scientists will benefit from easier access to the additional data available the R2R repository, including cruise metadata, names of participants in a cruise, types of data collected during a cruise, links to national archive products related to a cruise, etc. These data sets will be able to be incorporated into future data accessibility strategies to be put in place for WHOI investigators.
