An important metric of center productivity is peer-reviewed publications authored by center-funded scientists. Since 1994, over 440 papers have been published or are currently in press in peer-reviewed journals. During this period, the average number of publication per year is twice the average number of publications per year, 19, for the previous 10-year period (186 publications from 1985-1994).
Scuba diving projects account for the largest proportion of peer-reviewed publications since 1995; 245 total publications (70 percent). This is not surprising, however, since most of the center's resources over the last eight years have been directed towards diving programs for reasons previously discussed. Submersible projects account for 79 publications (23 percent). Submersible publications peaked in 1999 and have gradually declined, a trend that will most likely continue as the center funds fewer submersible projects than in the past. ROV projects account for the fewest number of publications, 26 (7 percent) (Figure 5.2). This is not surprising since a limited number of principal investigators have submitted proposals to use ROVs exclusively. Oftentimes, PIs use ROVs to augment diving projects. It is anticipated, however, that recent upgrades to the center's Phantom SII will make the system more responsive to scientist's needs for quantified data. Also, ROV's are often used for other tasks that may not result in refereed publications, such as long term monitoring, search and recovery operations, or video documentation. Non-refereed publications are often more difficult to track. Several reasons include that principal investigators often do not consider the value of such publications when reporting accomplishments. From 1995-2002, 76 non-refereed publications are reported for center-supported scientists. It is anticipated that this number may be under-represented by two or threefold.
