Journal Articles

El Nino and La Nina
Article: "Impact of El Niño / Southern Oscillation on Low-flows in South Georgia, USA". Pierre G.F. Gerard- Marchant and David E. Stooksbury. Southeastern Geographer 2010 p. 218-243

Purpose and Results: This research takes a look at the influence of the El Nino/La Nina weather patterns influence on several streams in Georgia. Several streams in Georgia were evaluated at different times of the year and evaluate the effect of the weather patterns on the low-flows of the streams. Gerard- Marchant and Stooksbury found that the low-flows were lower in the months of the El Nino/ La Nina climate events and higher in the neutral months of the year such as November to April.

Red Tide
Article:"Implications of Harmful Microalgae and Heterotrophic Dinoflagellates in management of sustainableMarine Fisheries". JoAnn M. Burkholder.  Ecological Applications 1998 p. 37-62
 Purpose and Results: This article looks at the many types of  Dinoflagellates that cause harm to fish and lists the toxins they produce. Red tide can be a very big problem in a fishery due to the large amount of fish produced there and the intended use of those fish, feeding a population. Burkholder goes on to note that Dinoflagellates and Red tide can," Accumulating evidence indicates that these harmful species significantly affect marine fisheries at the population level, well beyond the obvious acute impacts of fish kills" (p. 54). This shows that Marine fisheries can be in great danger not only due to lost fish, but also a threat to its potential consumer.

Burkholder goes on to state that there is a need for the Red Tide toxins to be identified and an economical means of testing and remediation need to be researched.
