A dataset with field names and field descriptions for the included tables.

am_meta

A data frame:

table: table name
field: field or column name
description: explanation of the field content
type_mysql: original field type in the source database
type: field type when used from R

The metadata is provided as a data frame with the table name, field name, field description and original data type in the AquaMaps.org source db.

There are five tables:

speciesoccursum_r: This table provides general information about taxa, such as identifiers and taxonomy for mapped species, and allows for searching. This is a simplified version, excluding fields in the source database which are used for internal purposes. NB: To be updated when invasive, resilience and IUCN fields are filled and m_invertebrates field is updated.
hcaf_species_native: This table stores native habitat map data; usually referred to as HSPEC-native. This is a simplified version, providing only overall probability of occurrence of a species in a cell. Contact the AquaMaps team if you are interested in the individual probabilities of occurrence (depth, temperature, salinity, primary production, sea ice concentration, bottom oxygen, distance to land). NB: May be updated in the future with a version that includes records where Probability=0 to explicitly show cells where species is not predicted to occur within its known native distribution.
hspen_r: This table provides the parameters used in maps from AquaMaps, such as the species environmental envelope for each mapped species. The data is relevant mostly for single species maps.
hcaf_r: This authorityfile describes some attributes for 0.5 degree raster grid cells with species presence in the data. The data in this table excludes future environmental parameter fields. Contact the AquaMaps team if you are interested in the future environmental parameters. Available datasets correspond to IPCC RCP 2.6 (2100), RCP 4.5 (2050 and 2100), RCP 8.5 (2050 and 2100).
occurrencecells_r: This table provides the occurrence cells generated from assembled occurrence data and it is used to generate the species envelope for each mapped species. NB: Fields where null=No should be updated to 0=No.
