| Alternate names | Hawaii abyssal nodules and ecosystems | ||||||||
| Purpose | To determine the distribution of abyssal manganese nodules and characterize the environmental setting of the abyssal plains in U.S. waters far offshore Hawaii, including fauna on the nodules, within the sediments, and in the overlying water column. | ||||||||
| Location | Southernmost portion of the U.S. Exclusive Economic Zone, approximately 200 miles south of the Island of Hawaii. | ||||||||
| Info derived | seabed mineral presence; seabed mineral abundance; seabed mineral composition; seafloor sediment mineralogy and geochemistry; microbial community composition and diversity; benthic fauna composition and diversity; water column fauna composition and diversity; water column conductivity, temperate, and nutrient profiles | ||||||||
