Аннотация

Во второй половине августа 2021 г. на острове Большевик (Северная Земля) произошел прорыв ледниково-подпрудного озера Спартаковское. Объём спущенной из озера во фьорд Спартак воды составил около 376 ± 21 млн м3. Озёрная котловина наполнялась водой в 2016–2021 гг. существенно быстрее, чем в 2006–2016 гг. за счёт усиления поверхностной абляции на ледниках водосборного бассейна в условиях аномально теплого лета в 2018–2021 гг. Система “ледяная плотина–озеро” пришла к новому состоянию – сток в долину реки Базовая происходить более не может.
