A data storage tag (DST), also known as an archival tag , is a data logger that uses sensors to record data. Data storage tags usually have a large memory size and a long lifetime. Most archival tags are supported by the world. Permitted some tags are solar powered and allow the scientist to set their own interval; this battery can be used for significantly longer than battery-only powered tags.
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 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 collection by data storage tags can be used to infer locations of the animal when it is at large.   
Archival tags archive data to internal memory. Once they are recovered by the researcher. The tag is generally mounted to the animal by inserting the tag, and sewing the opening closed. Externally attaches tags to animals by running anchor lines through the dorsal end for most “fish” species. For turtles the tag is the epoxied to the shell of the turtle.
