Eastern Iceland rivers
Iceland, Islande
Rivers and surface water
- Type
- River or surface water
Rivers on basalt (basalt -0.35 ‰); island mean +0.63 ± 0.38 ‰ (n = 20). No glaciated catchment exceeds +0.8 ‰, against four out of seven non-glaciated ones; bedrock age plays no role. Eastern fjords and Fljótsdalur; steady-state trend. Indicative coordinates (centre of the region), no position per river in the paper.
