Full Citation Examples
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.

Abstract: |
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. |
Purpose: |
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. |

Data Quality
Quality Control Procedures Employed: |
Estimates of the colony sizes were made by the pilot using the laser scale without knowing any of the measurements from the prior years. 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. |

Approximate Percentage of Budget for these Data Devoted to Data Management: | None |
Do these Data Comply with the Data Access Directive?: | No |
Is Access to the Data Limited Based on an Approved Waiver?: | No |
Approximate Delay Between Data Collection and Dissemination: | 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. |
Actual or Planned Long-Term Data Archive Location: | To Be Determined |
If To Be Determined, Unable to Archive, or No Archiving Intended, Explain: |
Pending PIFSC's decision |
Approximate Delay Between Data Collection and Archiving: | 2 years |
How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?: |
On file at PIFSC and published in peer-reviewed journal |
Lineage
Lineage Statement: |
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). |
