A "user account" refers to a unique user created in Movebank by an individual or institution and associated with an email address. Accounts are free of charge, and registered users gain access to all of Movebank's advanced functions such as creating studies and uploading data, setting up live feeds, filtering data, Env-DATA annotation, and requesting and being granted access to other users' non-public studies.
A user account is not required to use Movebank. Unregistered site visitors can browse studies, view tracks and download data for studies to which the Public has been granted access by the data owners.
Note that user accounts are not equivalent to studies in Movebank. Rather, studies are containers for data associated with accounts, as created and maintained by the account owners. Users can manage multiple studies with a single account, and studies can be associated with multiple accounts.
