I’m glad you asked! Dave Burdick already gave you the low-down on the monitoring program, so now it’s time to give you a little more specific information on what we’re up to for this year. As the monitoring season quickly approaches, we find ourselves finishing up our analysis of data collected during the 2010 and 2011 monitoring seasons and assessing which types of additional reef health data we may be able to collect this year. As a variety of reef health indicators (mentioned in Dave’s blog post) have already been established within the program, it is time to add-on!
With the procurement of two multi-parameter data loggers, several types of water quality data will be collected starting with this year’s monitoring activities. Turbidity (the cloudiness of a fluid caused by individual particles), dissolved oxygen (the amount of oxygen dissolved in a medium, i.e. seawater), pH (the measure of acidity or basicity of an aqueous solution), conductivity (a way to indirectly measure salinity), and temperature will be collected at multiple locations across all monitoring sites, but with the installation of data loggers at two, possibly three, sites, data will be collected continuously for several months in these areas. The collection of water quality data, along with the continued collection of benthic habitat and fish community data, will allow us to better understand how these environmental
factors affect reef health on Guam.
