Field Notes
A group of GMRI staff went through the remaining downeast samples from the joint VS/DMR Dasysiphonia monitoring project. We had fun over lunch but it also looks like there is no Dasysiphonia farther downeast within DMR's sampling plots (a good thing!) Green team's sample: MLW for Harbor Is. was 24ft, their sample weighed 97g
Supporting Evidence

Green team looked through their whole sample and coulnd't find anything filamentous to be dasysiphonia that wasn't a green algae. The closest they found was this algae, which does not have the characteristics of dasysiphonia (single cell branchlets, multicelled main). This algae has vertebrae like cells with 'pincers' at the end. Green team used a prepared slide of dasysiphonia (from a different place) to cross check their findings.
