We Share the Same Air [1.1] is an automated sculpture exploring the ecological and atmospheric significance of peatlands as living surfaces and critical carbon sinks. At its heart, We Share the Same Air [1.1] consists of three transparent chambers arranged in a circular configuration. Two chambers house living sphagnum moss ecosystems—emblematic of healthy peatlands actively sequestering carbon dioxide—while a third chamber contains bare peat, representing degraded landscapes. A robotic arm at the centre of the installation moves with quiet precision, opening and sealing each chamber in turn, creating a rhythmic choreography. As the robotic arm seals a chamber, an embedded CO2 sensor captures atmospheric readings over ten minute intervals. Under grow lights the healthy sphagnum moss chambers show a slow drop in CO2 levels, mirroring the photosynthetic process, while the aerobic bare peat chamber highlights the contrasting release of carbon, a stark visualization of environmental degradation.
Bogs are more than geological layers; they are relational systems, processing the atmospheric, hydrological, and biological flows that define them. We Share the Same Air [1.1] extends this notion to include the gallery space itself, transforming the atmosphere into a site of interaction. The CO2 levels in the room are directly influenced by the presence of visitors, particularly during moments of density when human breath will dramatically elevate the CO2 concentration. This feedback loop between human bodies and the living systems within the chambers underscores the entanglement of our atmosphere with peatlands and with our own collective presence.
The installation’s technological interventions such as ultraviolet grow lights and moisture-regulating pumps, sustain the moss in a feedback loop of care and control. These same technologies—born of extraction and industrial systems—are reimagined here as tools of restoration and observation and care.

My current project at RHA Gallery studios & funded by Arts Council of Ireland Project Award explores technologies which read peatland ecosystems to unveil hidden interactions with a focus on the invisible mediums such GreenHouse Gas GHG flux. This work is facilitated by my continued work with researchers from National Parks and Wildlife Services (NPWS) and a new collaboration with a community-led peatland restoration project at Abbeyleix bog. One strand of this work involves the development of a series of artworks which respond to live data feeds from GHG flux monitoring surveys managed by NPWS at Peatland restoration sites. One of the methods being used to calculate (GHG) CO2 sequestration or emissions involves the use of eddy covariance flux towers. Eddy covariance is a key atmospheric measurement technique which measures an ecosystem’s “breathing” , allowing scientists to get a sense of the annual carbon cycle of ecosystems.
