"This supplemental environmental assessment (SEA) focuses on additional proposed activities and a newly proposed support vessel and analyzes the proposed amendment to extend the depths at which surveys would be conducted to 200 700 m and the addition of a survey site within federal waters around Mokumanamana; the newly proposed instrument deployments using a lander to secure the instruments in place for one year; and a new permit to allow for the operation of the R/V Kilo Moana in support of separately permitted activities to conduct the proposed deep sea research. Both the permit amendment and new permit would be jointly approved and issued by NOAA s Office of National Marine Sanctuaries, the United States Fish and Wildlife Service and the State of Hawai'i, as co-trustees of the monument. The assessment finds that the individual and cumulative impacts of the proposed action are not significant. Accordingly, the supplemental environmental assessment has resulted in a finding of no significant impact"--Cover letter summary.
