Cynthia "Cyndy" Chandler is an Oceanographer Emerita in the Department of Marine Chemistry and Geochemistry at the Woods Hole Oceanographic Institution. In the 1980s she participated in 18 research cruises, initially as a benthic taxonomist and later as a CTD technician. Her current research interests are in the field of Ocean Informatics, a field of study that lies at the intersection of computer and information science and oceanography. Following her sea-going years, she led marine research data management projects at WHOI for 30 years, pioneering the use information systems to facilitate oceanographic research with specific focus on: data management, curation and publication; database design; data system architecture; development of marine ontologies; marine metadata standards; and the use of Semantic Web technologies to facilitate the process by which ocean science data and information become knowledge. She was a co-PI for the NSF funded Biological and Chemical Oceanography Data Management Office (BCO DMO, http://bco-dmo.org/); Lead PI at WHOI for the Rolling Deck to Repository (R2R) project (http://www.rvdata.us), Lead PI at WHOI for the NSF EarthCube funded GeoLink project (http://earthcube.org/group/geolink); one of the US partners in the Ocean Data Interoperability Platform (ODIP) project (http://odip.org); and co-chair of the Marine Data Harmonization Interest Group of the Research Data Alliance (http://rd-alliance.org). In March 2015, she was elected co-chair of the International Oceanographic Data and Information Exchange (IODE, http://iode.org) of the UNESCO Intergovernmental Oceanographic Commission.
