Super pretty samples! What will you do with them now Mingyue? 😊

⛰️Field stats⛰️
1 measurement = 4min⏳
1 plot = 6 light conditions = ~38min⏱️ (personal best pace - no rushing - usually 45-50min).
1 day = 10 plots = 1 plant community🥬
We have 5 plant communities in total.
1 field season = 4 measurement rounds of the 5 plant communities = 1200 measurements🔃

Catch up: Part 2 (July 26th, dry heath) - #CarbonFluxes in control & warmed plots ( #OTC ≈ +1 °C), rapid weather shifts ⛅, plus plant height 🌱 and other environmental drivers' measurements.

How do we measure #CO2 and #CH4 exchanges from alpine-Arctic #tundra #ecosystems...
... when the weather changes so fast? ⛅
Here is how, in a control plot and a passively warmed plot of a dry heath at #Latnjajaure field station, 100m a.s.l. near Abisko, Northern Sweden, on July 26th, 2025.

A study from Sybryn Maes and the #ITEX network published in @nature.com shows a 30% increase in #EcosystemRespiration due to passive #warming with #OTC. But what about #NetEcosystemExchange? That is what I try to answer with my #LightResponse set-up.

Finally, the different light conditions, using shading nets to reduce radiations and a lamp from #Heliospectra to increase them, allow us to standardize the measurements despite variable weather conditions.

While measuring carbon exchanges in one plot, I measure soil temperature, soil moisture, and plant height in the following plot to get a better understanding of the mechanisms driving the changes in #carbonflux we observe with warming.

The small greenhouse on the right is an Open Top Chamber (OTC), it warms the air temperature by 1 degree. They are like small windows into the future. Measuring #CO2 and #CH4 exchanges inside and outside the #OTC helps us understand how #climatewarming will impact #carboncycling in the tundra.

Hi :) I would love to be added to the Starter Pack if it is still possible! Thanks ⛰️🌱❄️
