PPT-Offshore petroleum platforms and dissolved oxygen in the northern Gulf of Mexico

Derek G Bolser Geographic Information Systems in Water Resources November 29th 2016 Overview Background Objectives Data Methods Results Significance Rig Fusion Background Transient hypoxic zones are known to exist in the northern Gulf of Mexico. Oxygen enters the water as rooted aquatic plants and algae undergo photosynthesis and as oxygen is transferred across the air water interface The amount of oxygen that can be held by the water depends on the water temperature salinity and pressure G It is extremely difficult to measure both ’K. L. ‘ . and . 'a' . in a fermentation and, therefore, the two terms are generally combined in the term . K. L. a. , know as the volumetric mass-transfer coefficient. The majority of fermentation processes are aerobic. Therefore oxygen is an important requirement in aerobic processes like. Therefore, 192 grams of oxygen are required for the complete oxidation of 180 grams of glucose..

The hypoxic zone in the northern Gulf of Mexico refers to an area along the Louisiana-Texas coast in which water near the bottom of the Gulf contains less than 2 parts per million of dissolved oxygen, causing a condition referred to as hypoxia. .
