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.
Concurrent range zone and partial range zone (ISG, Figure b and c): The interval between the documented lowest occurrence of one taxon and the documented highest occurrence of another taxon. Concurrent range zone is used when the fossil occurrence results in stratigraphic overlap of the taxa (Figure b).When such occurrences do not result in stratigraphic overlap, the interval zone may be called a partial range zone (Figure c).3. The zone, or biozone, is the fundamental unit of biostratigraphic classification. A zone may be divided into subzones and/or grouped into superzones. Each biozone is given a unique name, which is compound and designates the kind of biozone.
