Temperature, discharge and light data for Ivishak Hot Spring, Alaska
https://data.eol.ucar.edu/dataset/106.350

Summary
The productivity of a perennial, Arctic spring-stream was investigated.
Ivishak Spring has the stable discharge (~131 L/s) and temperature (~4-8 deg
C) typical for springs. It is unusual, however, in having an annual cycle of
daylight from 24 hrs/d (summer) to 0 hrs/d (winter). It was tested from the
hypothesis that stored detritus would buffer carbon limitation during winter
when gross primary production (GPP) is minimized, resulting in constant rates
of community respiration (CR) year-round due to constant temperatures.
Open-channel methods were used to measure GPP and CR monthly from March 2007
to August 2009. Mean annual GPP was 458 gC/m2. Such a level is typical for
temperate desert streams but was surprising for an Arctic stream. Annual CR
(887 gC/m2) was also remarkable. The high metabolism of this stream is
explained by an open canopy, moderate year-round temperatures, stable bed, and
high bryophyte biomass (48 gAFDM/m2). Strong seasonal cycles of GPP were
mirrored by CR (r=0.65) indicating the possibility of carbon limitation during
winter. This result falsified the hypothesis that CR would be relatively
stable year-round due to a detritus buffer and constant temperature.
