Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL acknowledgement String This dataset aggregates silicate observations from hypoxia and nutrient data collected by the Mineral Management Service (MMS) of the Department of the Interior from 1922 to 2014. These historical collections of over 19M data records were initiated by the late Dr. Mathew K. Howard, then the Data Manager at GCOOS, and were only recently reprocessed and published.
attribute NC_GLOBAL cdm_data_type String Point
attribute NC_GLOBAL comment String The silicate hypoxia and nutrient data collected by the Mineral Management Service (MMS) of the Department of the Interior from 1922 to 2014. Data were taken from 34,400 stations from 80 participating organizations. These historical collections of over 19M data records were initiated by the late Dr. Mathew K. Howard, then the Data Manager at GCOOS, and were only recently reprocessed and published. Note that in 2011, MMS became the Bureau of Ocean Energy Management (BOEM), Bureau of Safety and Environmental Enforcement (BSEE), and Office of Natural Resource Revenue (ONRR).
