2006 Ocean Drilling Citation Report Overview of the Ocean Drilling Citation Database The Ocean Drilling Citation Database, which contained almost 22,000 citation records related to the Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) in February 2006, is produced by the American Geological Institute (AGI). The database has been on line since August 2002. Beginning in 2006, citation records related to the Integrated Ocean Drilling Program (IODP) have also been included. To generate the GeoRef database, AGI indexes and records citation records from approximately 3,500 foreign and domestic publications (called “serial” in this report), as well as books, reports, serial conference proceedings, monographs, maps, and abstracts published in serial publications but not presented at meetings or conferences (called “abstracts and meetings” in this report), and maps, videos, books, monographs, and theses (called “miscellaneous” in this report). In addition, AGI obtains citation information from international data-exchange partners in Australia, Canada, China, Finland, Germany, Hungary, Italy, the Netherlands, New Zealand, Poland, Russia, Spain, and the United Kingdom. They also have arrangements to acquire metadata with many publishers, including Elsevier, the American Association for the Advancement of Science, Copernicus, Wiley, and 22 of the Geoscience World publishers. There is no guarantee that all publication venues for program research are included, but scientific publications throughout the world are represented. The Ocean Drilling Citation Database is created by AGI by using a series of keywords to extract a subset of citation records related to DSDP, ODP, and IODP research from the AGI GeoRef database. The database resides on the AGI server (http://odp.georef.org/dbtw-wpd/qbeodp.htm ) and is updated on a weekly basis from the GeoRef database. Users can also access the database via IODP U.S. Implementing Organization (USIO) Web site (http://iodp.tamu.edu/publications/citations/database.html ) and may download data into common bibliographic software.

Since 1999 the Publication Services Department at ODP and, starting in 2004, the IODP USIO on behalf of IODP has produced annual studies of the Ocean Drilling Citation Database. The results of these studies have been included in panel reports and have been used to track program publication trends as well as provide individual reports to member countries. The USIO receives a copy of the citation database from AGI annually on CD-ROM, and this disc is used to generate citation reports and provide statistics for the program and affiliate organizations that request citation data.

2006 Ocean Drilling Citation Report

Overview of the Ocean Drilling Citation Database The Ocean Drilling Citation Database, which contained almost 22,000 citation records related to the Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) in February 2006, is produced by the American Geological Institute (AGI). The database has been on line since August 2002. Beginning in 2006, citation records related to the Integrated Ocean Drilling Program (IODP) have also been included. To generate the GeoRef database, AGI indexes and records citation records from approximately 3,500 foreign and domestic publications (called “serial” in this report), as well as books, reports, serial conference proceedings, monographs, maps, and abstracts published in serial publications but not presented at meetings or conferences (called “abstracts and meetings” in this report), and maps, videos, books, monographs, and theses (called “miscellaneous” in this report). In addition, AGI obtains citation information from international data-exchange partners in Australia, Canada, China, Finland, Germany, Hungary, Italy, the Netherlands, New Zealand, Poland, Russia, Spain, and the United Kingdom. They also have arrangements to acquire metadata with many publishers, including Elsevier, the American Association for the Advancement of Science, Copernicus, Wiley, and 22 of the Geoscience World publishers. There is no guarantee that all publication venues for program research are included, but scientific publications throughout the world are represented. The Ocean Drilling Citation Database is created by AGI by using a series of keywords to extract a subset of citation records related to DSDP, ODP, and IODP research from the AGI GeoRef database. The database resides on the AGI server (http://odp.georef.org/dbtw-wpd/qbeodp.htm) and is updated on a weekly basis from the GeoRef database. Users can also access the database via IODP U.S. Implementing Organization (USIO) Web site (http://iodp.tamu.edu/publications/citations/database.html) and may download data into common bibliographic software. Annual Ocean Drilling Citation Report Introduction Member countries and funding agencies have long been interested in how program-related research is being disseminated into the scientific community through publications, and the study of the records in the Ocean Drilling Citation Database can provide this information. Since 1999 the Publication Services Department at ODP and, starting in 2004, the IODP USIO on behalf of IODP has produced annual studies of the Ocean Drilling Citation Database. The results of these studies have been included in panel reports and have been used to track program publication trends as well as provide individual reports to member countries. The USIO receives a copy of the citation database from AGI annually on CD-ROM, and this disc is used to generate citation reports and provide statistics for the program and affiliate organizations that request citation data. The annual CD-ROM provides a snapshot of the database at a specific point in time each year, which allows year-to-year comparisons to be made. A time lag exists between the dates new papers are published and the date a record of the paper is entered into the GeoRef database, depending on the source from which AGI acquires its

information. The CD-ROM production date is timed to best attempt to include most publications from the previous calendar year. Reports that document statistics by country are based on author affiliation (institutions and countries of contributing authors). Approximately 10% of the records in the database have no affiliation listed. Prior to 1975, AGI did not record affiliation information. In addition, many records lack such information simply because many publication venues do not require it. The number of records in the database without country affiliation information remains relatively constant from year to year because this information is now required by most publishers and AGI. The 2006 Study The CD-ROM produced at the end of February 2006 contains 21,520 records. These records can be divided into program (39%) and nonprogram (61%) citation records. These percentages have remained fairly consistent throughout each annual study since 1999 (Figure 1). For the 2006 study, program citations include publications produced and published directly by DSDP or ODP. Starting in 2007, the annual study will also document IODP publications. Program publications covered in the 2006 annual study include the Initial Reports of the Deep Sea Drilling Project and the Proceedings of the Ocean Drilling Program volumes as well as the ODP Scientific Prospectus, Preliminary Report, and Technical Note series but do not include the JOIDES Journal. Nonprogram records include citations for serials, abstracts and meetings, and miscellaneous (books, maps, videos, theses, etc.). Figure 2 shows a comparison between the number of records for program publications and each category of nonprogram publications from 1969 through the end of 2005. Figure 3 shows a year-by-year comparison between the number of citations for program publications and nonprogram serial publications. The focus of much of the annual study is on nonprogram publications, with an emphasis on peer-reviewed serial publications. Of special interest are nonprogram peer-reviewed serial publications produced by authors affiliated with program member countries. Authors from approximately 80 countries have contributed to DSDP and ODP nonprogram publications in all citation record categories (abstracts and meetings, serial, and miscellaneous) (Table 1). Because scientists may be affiliated with more than one institution or country over time, reports are based on the country affiliation of the first author at the time of publication. Although countries such as the Soviet Union (USSR) and Czechoslovakia have divided into new geographic and governmental entities, the number of records attributed to each is still recorded under USSR and Czechoslovakia. This reflects an effort to report these data in a manner that is historically consistent rather than in a manner that reflects current political boundaries. The footnote to Table 1 denotes the current national affiliation of first authors from specific segments of these two reorganized countries. The 2006 CD-ROM includes records of 11,000 nonprogram publications whose first author was affiliated with a program member country. Authors from countries that were members of ODP at the conclusion of ODP drilling in September 2003 account for 10,608 of these publications (see Table 2 for a breakdown by country). Approximately 55% of these publications were first-authored by authors from the United States. The member countries that were the top ten producers of nonprogram publications from 1969 through 2005 are featured in Figure 4.

DSDP- and ODP-related research has been published in more than 900 nonprogram publications. Although many of these publications consist of abstracts or publications that have arisen from professional meetings, a significant number of peer-reviewed journals have published 60 or more DSDP- or ODP-related scientific papers. These journals and the number of program-related papers published in them are found in Figure 5. The figure footnote lists an additional 20 serial publications that have published 30 or more program-related publications. For the peer-reviewed journals that have published 60 or more DSDP- or ODP-related publications, Figure 6 shows the annual number of scientific papers per journal. Program publication productivity has generally been tracked on a year-by-year basis rather than the leg-by-leg scheme. However the program has also reviewed publication data by leg to track whether beginning with Leg 160, when scientists were given the option of publishing their postcruise research in peer-reviewed journals rather than in the ODP Proceedings, the ratio of publications in program vs. nonprogram venues has changed. Figure 7 presents the number of papers published in the ODP Proceedings Scientific Results volumes compared to the number of papers that have appeared in the nonprogram venues. Although many scientists have elected to publish their research results in peer-reviewed journals, the majority have elected to publish in the ODP Proceedings Scientific Results volumes. What appears to be a progressive drop in the number of ODP publications per leg since the beginning of the program is attributable to three primary factors: research related to more recent ODP legs is ongoing, the final volumes of the ODP Proceedings Scientific Results series will not be completed until late 2007, and there is a lag time from publication of research papers to entry of those records in the Ocean Drilling Citation Database. Annual Updates On behalf of IODP, beginning in 2007 the annual Ocean Drilling Citation Report will be updated based on the data that exist in the AGI Ocean Drilling Citation Database as of February of each calendar year and made available online by October of that same year by the USIO. IODP funding agencies, implementing organizations, program management offices, or individual member countries may request customized reports (contact [email protected]).
