Probation ProgramProbation ProgramAny concerns with overall observer data quality -submission errors, communications, timeliness of data, under-sampling, poor captain interviewsCease conducting trips and schedule a debriefing in Woods HoleA performance plan is drafted and must be followed to resume standingGenerally three trips are completed, with each trip completely reviewed and approved before re-deploying Become non-eligible for bonus during probation period (usually 30 days)Emergency Probation Action– Invoked if there was reason to believe some egregious

violation of procedures or protocols had been committed– Pending an investigation – Usually results in decertification

Completeness = the time between the first and last baskets ÷ total pumping time(e.g., pumping from 1:00 - 2:00, first basket at 1:10, last basket at 1:55 = 75% complete)

Evenness = the shortest gap between baskets ÷ the longest gap between baskets (e.g., longest gap of 20 minutes, shortest gap of 10 minutes = 50% even)
