Photographs from the UM Biological Station and AmeriFlux towers. Click on any of the pictures to view a slideshow. Hemispherical image from the top of the 46-meter UMBS-Flux meteorological tower. Instrumentation above the UMBS canopy is used to estimate canopy-level carbon uptake. The UMBS meteorological tower is 46 m tall with gas sampling ports at 8 different heights. Physiological measurements such as soil respiration, pictured here, are also used to estimate carbon storage at the UMBS-Flux site. Soil respiration even occurs when snow is on the ground! Soil moisture, an important driver of carbon cycling in soils, is measured using time domain reflectometry. Leaf-level photosynthesis is measured in the top of the canopy. Biometric measurements, including those of fern biomass and radial tree growth, are used to estimate carbon storage at UMBS. At the end of a long day of research at UMBS, students, researchers and faculty unwind at a social.
