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!) Red Team's data: MLW is 20ft for Allen Is. site

(Posting for the red team) The red team scoured their whole sample for anything matching the description of dasysiphonia japonica. They were unable to find something that matched any of the key characteristics of dasysiphonia. They did find this really cool 'thumb' algae (or is it something else?) that has these little siphon cups that look like a hitchhiker's thumb. They called it the hitchhiker algae.
They used a prepared slide of dasysiphonia as a reference to double check their findings and confirm nothing in their sample was d. japonica.
