Explanation of variables:
Date: Dates always in yearmonthday 
Channel: Channel ID from 1-12
Channel_location: Location within channel, 1 being at the top and 10 at the bottom
Cyano_ug_cm^2, Green_ug_cm^2, Diatoms_ug_cm^2, Total_Chla_ug_cm^2: Chlorofyll a data from Benthotorch in micrograms per cm2. Total is the sum of the three groups
Location: Location within stream in relation to the clearcut, up being upstream of clearcut, CC being within the clearcut and downstream being downstream from the clearcut
Site: Site is the location within the location in meters away from the starting point
Replicate_Nr: Replicate estimate with the benthotorch
Dark_Light: Whether the incubation was done under dark or light conditions
GPP_CR: Whether the incubation was for GPP or CR
Time: Time stamp in hr:min
Start_Stop: If it is the starting value or end value
Replica: Each treatment was replicated three times, i.e replica 1-3
Treatment: Agar (control), nitrate addition or carbon addition in the nutrient diffusion substrate
Temperature_C: Temperature in the incubated water, in degrees celcius
O2_satutation_%: oxygen saturation in the incubated water estimated with a handheld oxygen probe (YSI, proDO)

O2_concentration_mg_ O2_L-1: difference in oxygen concentration in mg per litre in the incubated water between start and stop of incubation
GPP_mg_O2: Total oxygen production in mg O2 
Incubation_time_h: Total incubation time in hours
GPP_or_CR_µg_O2_cm-2_h-1: GPP or CR in the incubation in microgram O2 per surface area (cm2) and hr
central_european_time: date and time of oxygen concentrations estimated in the streams as central european time from the miniDOT dissolved oxygen loggers
temperature_water_deg_C: water temperature measured with the miniDOT dissolved oxygen loggers
DO_observed_mg_L-1:dissolved oxygen concentration in the streams from the miniDOT dissolved oxygen loggers
