Field Notes
One challenge I ran into was avoiding bubbles in slides and photos. I did find phytoplankton on both specimens. From what I have observed there seems to be no signs of dasysiphonia except one piece of algae that was so close to being dasysiphonia.
Supporting Evidence

This proves that I did not find dasysiphonia because there is a multi-celled branch which is a common factor in non-dasysiphonia algae which proves along with the fact that it is not red that it is not dasysiphonia.

This proves I did not find dasysiphonia for two reasons, it is not red and it multi-celled tips and branches yet dasysiphonia has both of those factors.

Although we thought that this was dasysiphonia it turned out not to be. Three reasons it was thought to be dasysiphonia was because it was red, had single celled branches, and it had axial growth yet it did not have multicellular stems or a shepherd's hook.

You have (at least) a couple of different algal species here, neither of which is Dasysiphonia. The first image, and probably the second, shows Polysiphonia. The third image shows Ceramium.

Thanks for your work on this!
