Marine alien and/or invasive algae species surveys, Hawaii state-wide in 2000 and Kaneohe Bay, Oahu, Hawaii during 2000-2002 (NCEI Accession 0001007)

Baseline surveys were conducted at numerous sites around each island, including those identified as "hotspots" by the Department of Aquatic Resources, around the islands of Hawaii, Maui, Molokai, Oahu and Kauai. A total of 72 sites with 13 in Kaneohe Bay, Oahu alone. Alien and/or invasive algal abundance were ranked on a scale of 0 to 10 (0=0% cover, 10=100% cover) and includes habitat type (e.g.. sand, lava bench, coral, rock, artificial substrate) and pertinent environmental correlates (e.g. depth, proximity to shore) at each site where invasive species are encountered. Sites where alien species presence have been documented in the past were resurveyed.
