The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL acknowledgement String We would like to acknowledge the efforts by PARC, Leidos, Axiom Data Science, Metron, University of Miami, GDA, NIWC Pacific, NUWC Newport, NRL Stennis, NSWC Dahlgren, and DARPA that made this dataset possible.
attribute NC_GLOBAL cdm_data_type String TimeSeries
attribute NC_GLOBAL cdm_timeseries_variables String imei
attribute NC_GLOBAL comment String Data provided was collected by low-cost, environmentally friendly, intelligent floats that drift as a distributed sensor network. Each drifter manages a suite of commercially available sensors to collect environmental data such as ocean temperature, sea state, and location. Data is primarily processed at the edge, and processed reports are sent via satellite and aggregated into the provided dataset.
