Ecosystem metabolism for an arctic warm spring-stream (Ivishak Hot Spring, Alaska)
We investigated the productivity of a perennial, Arctic spring-stream. Ivishak Spring has the stable discharge (~131 L/s) and temperature (~4-8 degrees Celsius) typical for springs. It is unusual, however, in having an annual cycle of daylight from 24 hrs/d (summer) to 0 hrs/d (winter). We tested th...

We investigated the productivity of a perennial, Arctic spring-stream. Ivishak Spring has the stable discharge (~131 L/s) and temperature (~4-8 degrees Celsius) typical for springs.
