6722 Data Set Published / External 7842 EOP Optical Surveys Project Completed Gold coral (Gerardia sp.) trees that were inspected years earlier on Pisces submersible dives were revisited and their change in size measured. The fishery for Gerardia operates using an estimate of average growth at 6mm/yr which would yield adult trees in a span of a few to several decades. In contrast independent radiometric studies suggest that large adult Gerardia colonies could be as much as a millenia old. The intent of this work was to revisit corals that had been inspected earlier and see if any appreciable growth could be seen. If not then the 6mm/yr estimate could be dismissed. Used to generate a report/presentation for the precious coral planning team and the council process. Results are to be published in a peer reviewed journal.

For this reason, some follow-up measurements are less than the initial from years earlier because growth is slow and the error in estimates is on the order of 5cm. No None No No Collection conducted in 2007, 2 years to archiving Not a continuous data set, project specific to address a management question. Time spent working with university collaborators on supporting radiometric work. To Be Determined 2 years On file at PIFSC and published in peer-reviewed journal There are photo, maps, and track lines associated with this data but the focus was to measure height and width of gold coral colonies once using a pair of laser dots then to remeasure them years later on a return visit. Testing the hypothesis that gold coral colonies grow at 6cm/yr (hypothesis rejected). gov.noaa.nmfs.inport:6722 Christopher Tokita 2007-12-12T09:49:41 SysAdmin InPortAdmin 2026-06-15T22:15:18 2017-07-27 Pacific Islands Fisheries Science Center PIFSC 1845 Wasp Blvd. Honolulu HI 96818 USA 808-725-5300 https://www.pifsc.noaa.gov 8:00 a.m. - 4:30 p.m. 1001 Public No No 2017-07-27 1 Year 2018-07-27
