Sorry, no etymologies found.
The Arctic has some of the largest rivers in the world (e.g., the Lena, Mackenzie, Ob, and Yenisey); numerous permanent and semi-permanent streams and rivers draining mountains, highlands, and glaciated areas; large lakes such as Great Bear, Great Slave, and Taymir; a myriad of smaller permanent and semi-permanent lakes and ponds; vast areas of wetlands and peatlands; and coastal estuarine and river delta habitats.
Several species in the Yenisey and Lena Rivers that prefer warmer boreal-plain habitats (e.g., roach, ide, common dace – Leuciscus leuciscus baicalensis, European perch, and ruffe – Gymnocephalus cernuus) are likely to move into the northern mouth areas of these rivers that are currently dominated by whitefishes and chars.
Shiklomanov A.  projected the impact of climate change on the annual and seasonal discharges of the rivers in the Yenisey drainage basin using a number of GCM scenarios and paleoclimate reconstructions as input to the detailed hydrological model developed by the State Hydrological Institute (Russia) (Table 6.13).

A weaker but still significant trend toward earlier freeze-up dates was found for portions of rivers (e.g., the Yenisey and Lena) in central and eastern Siberia .
The largest Siberian river basins (e.g., the Yenisey and Lena), in which permafrost is widespread, show an increase in runoff despite a decreasing trend in precipitation.
Recent trends of increasing E in the Yenisey and Mackenzie Basins (section 6.2.2) raise the possibility that P-E will actually decrease during the summer when E exceeds P, resulting in a drying of soils during the warm season.
Model projections are presented as averages for the Arctic Ocean and for the five largest arctic river basins: the Ob, Yenisey, Pechora, Lena, and Mackenzie.
For the period since 1960, the gauge-adjusted and basin-averaged data of Serreze et al.  show no discernible trends in mean annual P over the Ob, Yenisey, Lena, and Mackenzie Basins.
In particular, earlier rather than later freeze-up dates were found for rivers west of and including the Yenisey, whereas later freeze-up dates were observed for rivers in far eastern Siberia.
