6  Optional Data Tables

The following tables are optional for any data submission as long as the desired categories already exist in the database. For each table, the data needs to be submitted only once. For example, if a device has already been submitted with a deployment, and then referenced by a deployment that is submitted later, then the Device table including that device does not need to be included in the second submission as it will already exist in Makara.

Data Table	Definition	If/When to Submit
Devices	A specific piece of equipment used as part of a deployment (e.g., platforms, hydrophones, recorders, sensors, acoustic releases, gliders, arrays)	If there are new devices that are not already in Makara
Projects	A group of deployments	If multiple deployments are submitted that the data contributor would like to have grouped together, or if new deployments are submitted that should be grouped with deployments that are already in Makara. If a project was already created with previously submitted deployment(s) and there are new deployments to be added to that project, then another Project table does not need to be submitted.
Sites	The fixed location(s) where recordings were made over the course of one or more deployments, or general region for mobile deployments	If there are new deployment sites that are not already in Makara
Recording Intervals	The range of time and/or frequencies with compromised or invalid audio (this table is not for tracking duty cycled data)	If a deployment has periods of compromised data (duty cycling is accounted for in the Recordings table, not the Recording Intervals table)
Sensor Datasets	Metadata about the collection of sensor readings (e.g., temperatures)	If sensor data (e.g., temperatures) were collected on the deployment
Sensor Values	The timestamped sensor readings belonging to a Sensor Dataset	If sensor data (e.g., temperatures) were collected on the deployment
Tracks	Metadata about the collection of track data (e.g., position, speed, and other variables) associated with a mobile platform	If a mobile deployment is submitted
Track Positions	The instantaneous timestamped location, speed, etc. along the track of a mobile platform	If a mobile deployment is submitted
