Most of the 96 national monuments designated under U.S. law

are on land. The majority are managed by the National Park

Service, though some are administered by the Bureau of Land

Management and other agencies. At this point neither the

name of the proposed Mariana Trench Marine National Monu-

ment (MTMNM) nor the management structure has been de-

termined. For guidance one could review the process of the

recently designated Papahanaumokuakea Marine National

Monument (PMNM), which is placed within the purview of the

National Oceanic and Atmospheric Administration (NOAA)

for budgetary purposes.
