The International Ice Patrol and the IICWG Iceberg Subcommittee CDR Gabrielle G. McGrath

The International Ice Patrol and the IICWG Iceberg Subcommittee work together to provide aerial reconnaissance and collect environmental data to monitor and warn mariners of icebergs. This includes processing iceberg reports, running drift and melt models, and creating iceberg distribution products.
