Aggregate Existing Features

The geometric_features.aggregation module contains functions used to aggregate existing features to make new, larger ones. An example usage of these aggregation functions is to create masks for regional averaging.

Aggregating Ocean Features

Ocean Sub-basins

The function geometric_features.aggregation.ocean.subbasins() aggregates oceanic regions to make the following ocean subbasins: North and South Atlantic, North and South Pacific, Indian Basin, Arctic Basin, and Southern Ocean Basin.

Ocean Basins

The function geometric_features.aggregation.ocean.basins() aggregates oceanic regions to make the following ocean basins: Atlantic, Pacific, Indian, Arctic, Southern Ocean, Mediterranean, Global Ocean, Global Ocean 65N to 65S, Global Ocean 15S to 15N.

Meridional Overturning Circulation Basins

The function geometric_features.aggregation.ocean.moc() aggregates basins for computing the MOC: Atlantic, IndoPacific, Pacific and Indian

Antarctic Regions

The function geometric_features.aggregation.ocean.antarctic() aggregates regions of the Antarctic: Southern Ocean, Southern Ocean 60S, Eastern Weddell Sea Shelf, Eastern Weddell Sea Deep, Western Weddell Sea Shelf, Western Weddell Sea Deep, Weddell Sea Shelf, Weddell Sea Deep, Bellingshausen Sea Shelf, Bellingshausen Sea Deep, Amundsen Sea Shelf, Amundsen Sea Deep, Eastern Ross Sea Shelf, Eastern Ross Sea Deep, Western Ross Sea Shelf, Western Ross Sea Deep, East Antarctic Seas Shelf, East Antarctic Seas Deep.

Ice-shelf Regions

The function geometric_features.aggregation.ocean.ice_shelves() aggregates ice shelves and ice-shelf regions. There are 106 regions, so they won’t all be listed. See the resulting feature collection or the code itself for the full list.

Transport Transects

The function geometric_features.aggregation.ocean.transport() aggregates transport transects: Africa-Ant, Agulhas, Antilles Inflow, Barents Sea Opening, Bering Strait, Davis Strait, Drake Passage, Florida-Bahamas, Florida-Cuba, Fram Strait”, Indonesian Throughflow, Lancaster Sound, Mona Passage”, Mozambique Channel, Nares Strait, Tasmania-Ant Windward Passage.
