Fig. 5: BIMS application in the field.

a Representative images of the BIMS application in field, showing (left to right) drying, application, maneuvering, releasing, and tag recovery via radio signal. b The depth of the squid actively descends immediately after release as a function of time. c, d Adhered environmental sensors sampled the temperature (c) and luminance of RGB light (d) as a function of depth (b). e Schematic illustration of tag recovery via programable galvanic release and radio signal. f–i Accelerometer and gyroscope data for two ecologically important movement behaviors captured by the IMU. Gliding (g, f) represents a low-activity movement where the negatively buoyant animal descends in the water column. Jet propulsion (h, i) represents a high-activity movement and is often employed in series. Colors in (f–i), represent direction, where blue is forward motion (surge, x), orange is lateral motion (sway, y), and yellow is vertical motion (heave, z).
