Researchers in Estonia are employing advanced technologies to enhance seal research, particularly in recognition and monitoring efforts. The use of photographic identification is compared to the process of granting citizenship, as researchers are seeking to make their databases internationally accessible to track seals across the Baltic Sea. The technological capabilities now allow for the comparison of thousands of photographs in a matter of hours, which significantly aids researchers in identifying whether a specific seal has been spotted elsewhere.

In addition to photographic recognition, researchers on Saaremaa Island are utilizing drones equipped with specialized tools for assessing seals' weights, especially that of pups. This measure is crucial for determining both the health of the seals and their mothers, as well as the availability of food source in the area. Another innovative device is attached to the seals' backs, enabling tracking of their movements while also measuring sea depth, salinity, and temperature, thereby providing invaluable data on their habitat conditions.

The period of late winter to early spring is particularly intense for the researchers as it marks the time when seal pups are born on the ice. The emphasis on new technologies reflects a growing trend in wildlife research aimed at better understanding and conserving seal populations in Estonia and the greater Baltic region.
