On 11-2-2013 we, the benthic group, removed our 9 core samples from the preserved whirl-bags for fauna collection and preservation. We were successful in sieving all the unwanted material from the samples taken from our site at GTMNERR. The sediment and material that remained in the sieve was then stored in a labeled jar. From there 3 out of the 9 jars had all the remaining sample analyzed for fauna. In the previous week, when the samples were collected, they were preserved with a dye that binds to a particular protein staining fauna red. This made it far easier to identify organisms as we were sifting through the material under a dissection scope. The organisms that were collected were stored in a vial with 75% EtOH and labeled according to site. Before next Saturday we would like to have all our samples analyzed and all fauna preserved, as well as possibly begin the identification process. Everything seems to be going according to schedule and so far I've learned a few new lab skills. Also, I was impressed by the overall amount of organisms we've found so far in our 3 samples.
