Here is the eighth and final set of UD Citizen Monitoring Program Reports for 2013 covering the period from Sept 18 to Nov 5, so 7 weeks.
- The first and last 3 weeks of this period were pretty dry, but a prolonged noreaster filled the 4th week with over 6in of rain. Much of the sampling for bacteria and harmful algae followed the stormy weather.
- Although most sites showed improvement during the period, Low Dissolved Oxygen readings (< 4.0 ppm) persisted in a few canals and upper tributaries. Severely low readings (< 2 ppm) were limited to 2 dead-end canal systems.
- Accumulations of Nuisance Aquatic Vegetation were limited and minor.
- Total Enterococcus Bacteria (TE) levels were elevated in a few tributaries, a stream and a bayside site, but most sites had values below the geometric mean for the season.
- In the estuaries, some minor blooms persisted before the storm, but were gone afterwards. In the ocean, Karenia papilionacea and Pseudo-nitzchia spp. were present at background cell densities. Apparently, the noreaster drove background levels of K. papilionacea into the Indian River Bay and the mouth of the Delaware Bay.
