Kamchatka scientists for the first time, for the last 30 years, are monitoring the Avacha Bay
The research is carried out according to several parameters. The main goal of scientists is to assess the condition of plankton, as well as the sanitary condition of the water in the bay. Salmon migration routes pass through the bay, so the composition of the water must be monitored for the content of harmful substances: oil products, phenols, metals. According to official data, there are 74 sunken ships at the bottom of the bay, including 56 military ones.
“The results of analyzes of samples taken in 2013 showed that the most unfavorable sanitary situation is in the water area opposite Teatralnaya Square, where wastewater from the plant, Lake Kultuchny and from one of the city collectors are supplied,” the press service of KamchatNIRO said. "The highest concentration of microorganisms, E. coli and a pathogen dangerous for fish was found here."
Despite the contamination, most of the bay has a high potential for self-cleaning. As for the research of microorganisms, which can also be toxic, the scientists will make more accurate conclusions based on the results of a second, more extensive stage of research. It began this spring and will end in October 2014.
Recall that Avacha Bay is the second largest ice-free harbor in the world. The bay is 24 kilometers long, with a maximum depth of 28 meters. The reservoir is about 600 thousand years old.
