Data storage tag
A data storage tag (DST), also sometimes known as an archival tag, is a data logger that uses sensors to record data at predetermined intervals. Data storage tags usually have a large memory size and a long lifetime. Most archival tags are supported by batteries that allow the tag to record positions for several years. Alternatively some tags are solar powered and allow the scientist to set their own interval; this then allows data to be recorded for significantly longer than battery-only powered tags.
Operation
Data storage tags can have a variety of sensors; temperature, depth, light, salinity, pressure, pitch and roll, GPS, magnetic and compass. They can be used internally or externally in fish, marine animals or research animals. They are also used in other industries such as the food and beverage industry.
At the end of the monitoring period, the loggers can be connected to a computer and the data uploaded for analysis. Data collected by data storage tags can be used to infer locations of the animal when it is at large.
