PPT-OVERVIEW OF SUMMER DISSOLVED OXYGEN & CHLOROPHYLL IN NARRAGANSETT BAY

OVERVIEW OF SUMMER DISSOLVED OXYGEN amp CHLOROPHYLL IN NARRAGANSETT BAY CHRP Meeting MAY 19 2015 Heather Stoffel of Time Hypoxic Events Occur During Each Summer Month Stations Providence River amp Upper Bay. 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 Why is it Important Most aquatic organisms need oxygen to survive and grow x Some species require high DO such as trout and stoneflies x Other species do not require high DO like catfish worms and dragonflies If there is not enough oxygen in the wat ASHTON CAUDLE, PATRICIA MULLER, SARAH RUTLAND, MATT EVANS, & ROY KIM. BACKGROUND:. Primary productivity is the production of organic compounds from atmospheric or aquatic carbon dioxide mainly through the process of photosynthesis.. 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.. Stormwater. . Contaminants in Wetlands and Biofilters. Amanda Jimenez. Environmental Engineering. UCI.

Ventura Pier, Harbor and Estuary. Objective. : . Sample water at each location to compare abiotic differences in the water to the plankton distribution.. Methods. : . Use a plankton net to concentrate organisms for comparison at each location. Analyze water samples at each location to find pH, dissolved oxygen, phosphate levels, nitrate levels, temperature and turbidity.. L. ‘ . and .
