Oxygen utilization rate
WebJul 10, 2024 · The relationship between age and oxygen is one that is often assumed in oceanography to be relatively simple. Because oxygen utilization rates are difficult to directly measure in the ocean, it is commonly assumed that the apparent oxygen utilization divided by the water age is a good representation of respiration. WebNov 1, 2024 · The dissolved oxygen minimum zone is centered at σ 0 ~27.2–~27.4 kg m −3 (800–1000 m). T-S patterns were similar at SEATS, which were sampled during both cruises (2016 and 2024).

WebAug 1, 2011 · Humans use oxygen to extract approximately 2550 calories (10.4 MJ) from food to meet daily energy requirements. This combustion requires about 22 mol of dioxygen per day, or 2.5 × 10 − 4 mol s − 1. This is an average rate of oxygen utilization of 2.5 × 10 − 18 mol cell − 1 s − 1, i.e., 2.5 amol cell − 1 s − 1. WebDirect measurements of oxygen utilization of a well-defined muscle show that contracting muscles utilize oxygen within a few seconds of exercise onset and that it takes some 45 s before oxygen extraction is maximal.
WebJul 16, 2024 · The apparent oxygen utilization rate (AOUR), calculated from oxygen deficiency and water age, reflects oxygen consumption primarily due to microbial respiration. Oxygen consumption rates in the ocean have for over 50 yr been reported as a function of depth with no theoretical basis.
