Ecological studies of the aquatic organisms using data loggers have been carried out in order to research a resources state of the aquatic organisms. One of data loggers to be used in the studies is an archival pop-up tag. Archival pop-up tags widely used have an ARGOS transmitter for facilitating recovery of tags. On the other hand, they have few sensors such as an illuminometer, a pressure sensor and a temperature sensor by the reason of a small-capacity battery and small buoyancy. Therefore it is difficult to know finescale movements of aquatic organisms from data collected by typical pop-up tags with an ARGOS transmitter. We have developed a smart pop-up tag which has a 3-axis accelerometer and a 3-axis angular velocity sensor in addition to an illuminometer, a pressure sensor and a temperature sensor. This tag allows us to obtain fine-scale movements of target animals. This tag also has an ARGOS transmitter which is driven by a solar cell. We have verified that the tag works properly in a pretest.
