A novel estimate of ocean oxygen utilisation points to a reduced rate of respiration in the ocean interior
The Apparent Oxygen Utilisation (AOU) is a classical measure of the amount of oxygen respired in the ocean’s interior. We show that AOU systematically overestimates True Oxygen Utilisation (TOU) in 6 coupled circulationbiogeochemical ocean models. This is due to atmosphere– ocean oxygen disequilibria in the subduction regions, consistent with previous work. We develop a simple, new, observation...
متن کاملa study on rate making and required reserves determination in reinsurance market: a simulation
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
Steady-state measurements of respiration rate with an oxygen electrode.
The respirometer is shown in Fig. 1. The cathode was made from gold wire of 0.51 mm diam which was coated with glass of low melting point (4). After mounting the cathode as shown in Fig. 1, the gold and its glass coating were ground to a flat surface and polished using a series of carborundum grinding powders. The cathode was maintained at -0.45 V with respect to the calomel electrode. The elec...
متن کاملAquatic Respiration Rate Measurements at Low Oxygen Concentrations
Despite its huge ecological importance, microbial oxygen respiration in pelagic waters is little studied, primarily due to methodological difficulties. Respiration measurements are challenging because of the required high resolution of oxygen concentration measurements. Recent improvements in oxygen sensing techniques bear great potential to overcome these limitations. Here we compare 3 differe...
متن کاملA Mathematical Model for Indian Ocean Circulation in Spherical Coordinate
In recent years, the Indian Ocean (IO) has been discovered to have a much larger impact on climate variability than previously thought. This paper reviews processes in which the IO is, or appears to be, actively involved. We begin the mathematical model with a pattern for summer monsoon winds. Three dimensional temperature and velocity fields are calculated analytically for the ocean forced by ...
