Final answer:
Reports from credible sources within 15 statute miles will be disseminated, followed up with supporting information, and appended to the observations.
Step-by-step explanation:
The reports from credible sources within 15 statute miles will be disseminated longline and locally. This means that they will be shared widely and made available to the relevant parties in the area. The reports may also be followed up with the supporting OWS, meaning that any additional information or data needed to understand or verify the reports will be provided. The reports may also be appended in the remarks of the observation, which means that they will be included as additional information or comments on the original observation.
