Item Identification

Title: EOP Gold Coral (Gerardia sp.) Growth Measurements
Status: Completed
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.

Access Information

Security Class: Unclassified
Data Access Procedure:

Request access to the legacy data set

Data Access Constraints:

Not applicable

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.

Data Management

Have Resources for Management of these Data Been Identified?: No
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
If Delay is Longer than Latency of Automated Processing, Indicate Under What Authority Data Access is Delayed:

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).
