Event Title

Too Much Sun? Growth Rates of the Northern Star Coral, Astrangia poculata, in Various Light Levels

Description/Abstract

This project focuses on the growth rates of Astrangia poculata over time in different stressful situations based on light. The Astrangia colonies were collected from the JB Eskridge wreck at the Chesapeake Light Tower reef. A total of 20 nubbins, 10 symbiotic and 10 aposymbiotic, will be separated evenly under two different scenarios, an area of light that measures 400μmol/m2s and one that measures 80μmol/m2s. The methods that will be used to measure growth rates are photo Symbiodinium quantification from Winters et al. 2009, as well as the buoyant weight technique.
