Scientists on board the Bulgarian military research vessel Sv. Sv. Kiril i Metodii (RSV 421) continue to work on their scientific projects on Wednesday. Geologist Kalin Naydenov and mountaineers Doichin Boyanov and Kiril Doskov were able to take geological samples from rock outcrops in the Sopot Ice Piedmont, located near Half Moon Island, reported Bulgarian News Agency (BTA).
Ichthyologist and hydrobiologist Prof. Eliza Uzunova collected a specialized microplastic trapping net that she had placed in the area around Half Moon Island. She explained the process of preserving the collected material. “We'll wash everything out of the net, strain it through a very fine sieve, and use a steel funnel to cast it into jars of alcohol to preserve it,” the ichthyologist said. He added that the collected ice and snow is stored in a special refrigerator at -20C. Uzunova also pointed out the method of water testing by filtration. “We cut the filter, put it in a medium for the bacteria to develop, and the bacteria themselves are seeded on Petri dishes,” she explained.
