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.
Dead zone is a more common term for hypoxia, which refers to a reduced level of oxygen in the water. Hypoxic zones are areas in the ocean of such low oxygen concentration that animal life suffocates and dies, and as a result are sometimes called dead zones..One of the largest dead zones forms in the Gulf of Mexico every spring.ead zones occur in many areas of the country, particularly along the East Coast, the Gulf of Mexico, and the Great Lakes, but there is no part of the country or the world that is immune. The second largest dead zone in the world is located in the U.S., in the northern Gulf of Mexico.
