Scientists have improved the technology of tracking large fish and analysis of sea water

For some people it may seemsurprisingly, some fish swimming in the seas and oceans are equipped with electronic sensors. For example, using a device called Marine Skin, researchers can monitor the temperature and salinity of water at different depths of the seas, and this does not require the services of scuba divers. Recently, engineers from the King Abdullah University of Science and Technology have improved this technology by adding a number of innovations.

The old version of the device was attached to the bodies of sharksand whales, and consisted of non-toxic materials with flexible electronic components. The new version also does not harm the marine life, but it has become much more compact - it can be mounted on smaller fish. The design includes a standard set of sensors, a memory module and a “tablet” type battery, which lasts a year for a charge.

Unlike the original version, the noveltyprovides 15-fold sensitivity, is able to work at a depth of 2 kilometers and withstand 10,000 cycles of extreme flexion. The device is attached to the bodies of caught fish - unfortunately, it is impossible to receive real-time data, so they are read only after re-catching.

The development team is already working on the next one.version of Marine Skin. They plan to expand the amount of data collected, and allow the device to track the level of oxygen and carbon dioxide, as well as the movement of aquatic inhabitants.

The study of the underwater world is difficult, but extremelyinteresting occupation. Recently, scientists managed to find out that white sharks are able to withstand even a high content of heavy metals in the blood, as well as that they have bloodthirsty enemies.
