  • To determine the invasion threat to the NE Pacific of marine algae arriving on Japanese debris from the 2011 Great Tōhoku Earthquake and Tsunami, my colleagues and I identified the algal species on 42 of the most heavily fouled debris items that landed on the shores of Oregon and Washington between June 2012 and July 2016. Using both morphological and molecular methods, we identified 84 marine algal and cyanobacterial species and species complexes on these items and sequenced 51. Since many of these species are not well-described in the literature, a morphological account of the actual specimens has been prepared to assist in the detection of future invasions by these species in the NE Pacific. The series is divided into 3 parts: Part 1 – The tsunami event, the project overview, and the red algae, Part 2 – The brown algae, and Part 3 – The green algae and cyanobacteria. In Part 3 that follows, we provide pictures and descriptions of 21 green algae and 4 cyanobacteria and discuss some of the taxonomic difficulties we encountered. For additional information on all the algal and cyanobacterial species on debris, please see our related papers on the project cited on p. 2 of the text.
