Today, researchers of polar environmental phenomena from the University of Washington have published their new research on the disclosure of the mystery about why so-called poly lines are formed in the thick of the ice in Antarctica – huge sea holes in glaciers. Researches of 2016 and 2017 showed that climatic factors certainly play a certain role around glaciers, but they are not the main culprits of such incidents – that is why the team of researchers again decided to address this issue by equipping special systems with sensors and monitoring satellites that monitor the process.
Moreover, specialists from the University of Washington also pointed out the fact that they attracted sea lions to the work, which were also equipped with separate mobile and deformation-resistant sensors – thus, several parties and tools are involved in the project, thereby allowing to identify really interesting features Experts, on the basis of the conducted research and experiments, noted that among the main factors that cause such holes to appear, one can notice hurricane storms and unusual climatic conditions that occurred earlier in the Sea Weddel region of Antarctica.
At the moment, the diameter of the hole in this area of glaciers is registered at around 13 thousand square miles, while soon it is expected to increase to 19 thousand square miles, which represents a really interesting and excellent dynamics. However, experts from the United States have their own opinion on this matter and their own approach to establishing the truth.
They indicated that, by and large, they are interested in measuring the level of expansion of a hole not only in width, but also in depth, wanting to find additional — perhaps underwater — factors and features that make this process happen. Nevertheless, it is worth noting the fact that so far attracted instruments do not provide specific indicators.
