Vassiliy Shevchenko, the head of the organisation that maintains the weather stations, said a ship with provisions is making its way to Troynoy Island to bring aid - including dogs and more flare guns - to the beleaguered scientists. But it will arrive a month from now.
"Instructions were given to the Mikhail Somov expedition vessel that will reach the station in about a month," Shevchenko is quoted as saying, "to deliver dogs, as one of the station's canines was killed by a bear, and also flares and other pyrotechnical devices needed to scare the animals away."
A similar episode took place just a year ago. Five hungry polar bears circled a Russian weather station on Vaygach Island in Russia's far north, preventing its staff from taking sea readings.
"They sleep near the houses. Two of them walk together. They are aggressive. Recently they fought together near our house," one scientist was quoted saying by the Siberian Times.
The scientist described the terror involved in carrying out her daily work: "So we go, your head rotating 360 degrees. Yesterday we came out and a bear was near the house. Three times our engineer fired a small flare pistol, and the bear was not even scared. We managed to scare it off with a flare, but not far."
It's not unusual for polar bears to approach human outposts in the Arctic, where waste is often difficult to dispose of and attracts carnivorous predators. The phenomenon has intensified, though, due to climate change.
Melting sea ice and shifting patterns in the populations of the polar bears' marine prey stoke the desperation of bears, which are being forced to travel farther for food.
Shevchenko told TASS that he expects the bears to leave his scientists alone come the end of October, when the near-shore waters off the island freeze. But until then, the "siege" is expected to continue.
