Long-Term Heat Flux Formation Of The Large Russian Arctic Rivers And Its Transformations In Estuaries Under The Influence Of Climate-Induced And Dam-Induced Effects
The heat flux of the large rivers flowing into the Arctic seas of Russia plays an essential role in the thermal and ice regime of the lower reaches of these rivers and the southern part of the Arctic seas. However, estimates of the total value of heat flux and its spatial-temporal distribution requi...

The heat flux of the large rivers flowing into the Arctic seas of Russia plays an essential role in the thermal and ice regime of the lower reaches of these rivers and the southern part of the Arctic seas.
