Abstract: The metric is the ratio of maintenance craft workers to planners. This metric is used to measure the manpower planning work load of planners for comparison and benchmarking. This ratio identifies the level of work planning activities necessary to maintain a backlog of planned maintenance work.
Bathyal zone. The layers of the pelagic zone. The bathyal zone or bathypelagic â from Greek Î²Î±Î¸ÏÏ (bathÃ½s), deep â (also known as midnight zone) is the part of the pelagic zone that extends from a depth of 1000 to 4000 meters (3300 to 13000 feet) below the ocean surface. It lies between the mesopelagic above, and the abyssopelagic below.
Below the sunlit zone is the twilight zone where some light penetrates the ocean to a depth of 3000 feet. Viper fish, firefly squid, and the chambered nautilus live in this zone. The midnight zone extends from a depth of 3000 feet to the seafloor.he open ocean zone lies beyond the continental slope and contains 65% of the water in the oceans. This zone is divided further into three subzones. The sunlit zone is where photosynthesis takes place. Plankton and jellyfish are drifters that inhabit this zone.
