Squid tag movement data and environmental sampling acquired in November 2021 and May 2023 near Faial and Pico Islands, Azores archipelago.

ITAGs were used to measure squid movement dynamics. The sensor package was small (12.5 × 2.6 × 2.7 cm) and was affixed using surgical sutures . Additionally, ITAGs were neutrally buoyant, hydrodynamic, and focal tagged squid exhibited normal swimming and schooling behaviors with other conspecifics. ITAGs contain an inertial measurement unit (IMU) which measures acceleration, magnetic field strength, and angular velocity. These tags were used to measure the swimming behavior or free-ranging animals in the Azores region in November 2021, and May 2023. These data provide movement intensities, behaviors, and allow us to measure the environment including light, temperature, and the animal's depth. Here, we are submitting the tag data from the free-ranging animals in matrix form (.csv).
