Black Smokers is a sensory based work in two parts on the hydrothermal vent systems that may appear on the meeting point of techtonical plates on the deep sea ocean ridges. Thriving in a world of explosive heat and total darkness, The Black Smokers might be the origin of all life on earth. 

The work included a self – guided performance with sound and small sculptures made out of drift wood and shells in the garden of Cultural Calura Centre (CCC) installed in and below a dragon fruit tree. 

During the Biennale opening weekend, at sunrise and sunset, at Ponta Galera Beach, the work unfolded as a guided underwater immersion that led participants to float and explore the sea with small wood sculptures made from drift wood and shells gathered from across the archipelago.

In Caloura, Helle Siljeholm’s project delves into the geological unconscious of the island. Drawing on research into hydrothermal vents — “black smokers” that emit mineral-rich currents sustaining deep-sea life — she developed a self-guided performance that leads participants along São Miguel’s coastal thresholds. Through a choreography of sound, text, and embodied movement, Siljeholm reattunes the visitor’s perception to the mineral and thermal forces that pulse beneath the island’s surface. The work’s speculative sensibility bridges deep time and corporeal awareness, turning geology into a site of intimacy.
