Confidential
Only available to those with a valid non-disclosure agreement in place with the SEFSC.
Any paper copies of data set must be keep in a locked storage cabinet accessible only to NDA holder, within a locked office or lab that is accessible only to a limited number of the NDA holder's associates. Electronic copies of the data must be stored on a PC that is password protected/restricted to the NDA holder and located in a locked office or lab that is accessible only to a limited number of the NDA holder's associates. Alternatively the data can be stored on an oracle type data storage with access to the system restricted and access to the specific data table/tables restricted to the NDA holder.
Need SEFSC NDA. NDAs can only be granted to NOAA employees, contractors, or grantee's with a need for the data.
Contact data steward Beerkircher or SEFSC Miami Laboratory Fisheries Statistics Division Chief.
None for NDA holders with a specific need for the data. No access permitted for non NDA holders. Aggregated data may be available, contact data steward.
Usually defined in the NDA. Publicly available research results must conform to current aggregation procedures (rule of three).

Unknown. Likely only representative of the roundscale spearfish captured at these times and places by PLL vessels.
Nothing is known about the degree of agreement between individual measurements in the POPOL data set and the true measurements, as the observer collecting the data is the sole source of the information and it cannot be cross checked with alternate sources. Laboratory measurements are assumed accurate; although this assumption was never validated.
See above. The accuracy of analytical results to the “true” values cannot be determined as the true values cannot be calculated without 100 % observer coverage and multiple observers on each vessel. Neither situation has ever occurred during collection of POPOL data.
No limits. The species size range captured on board pelagic longline vessels can be easily measured by observers with standard hand measuring devices.
There have been no quantitative studies to detect potential bias in POPOL.
There are no known comparable data sets.
Only dead specimens could be measured; observations of live roundscale spearfish did not include the complete detailed measurements.
A hand centimeter measuring tool, collecting data to the nearest centimeter, can be expected to be very precise.

See above, specimen needed to be dead and brought on board by the crew in order for the observer to take the complete data needed.
