Despite the minimun of light, at depth of 166 m below ocean surface is possible to find live algaes.

In 2011 scientists interested in mapping the seabed habitats, using cameras in the cold waters of a glacial fjord in the Norwegian Svalbard archipelago in the Arctic Ocean, they found what they believe is a brown (Phaeophyceae) or red alga (Rhodophyta). 

Unfortunately, in the absence of voucher specimens, it is impossible to say with absolute certainty that the observed organisms are not in fact something else, such as a hydrozoan, but in every respect, the organisms certainly appear algal in nature. Superficially, is similar in shape to Desmarestia aculeata.

This report is not the deepest record of macroalgal presence in the world (there is a crustose coralline algae living at 189-268 m, in a seamount off San Salvador), but it may very well be the deepest macroalgal record to date for the high Arctic

My girlfriend and I went lichenizing on the coast yesterday.  She found this amazing lichen called Graphis scripta which is a crustose that looks like tree-writing!  Some of it made me think of Japanese, hieroglyphs, and runes.  We also found several other types she hadn’t collected yet around uni and it was loads of fun.  

Before she took this class, I never realized how many mosses and lichens are growing on almost every tree we pass!  I just never noticed them! 

It’s also been a great excuse to travel a bit this term, since lichen are so dependent on air quality.  Moving a bit outside urban areas, off roads, and into slightly different regions of the state have helped her amass the gigantic collection required for this course.

also, I am super proud of myself for collecting the graphis scripta samples from the trees.  I am a superior helper.
