ICARUS is presented as an audiovisual performance that explores sonic frequencies, water soundscapes and light. It raises awareness of the potential impacts of increased low and high-frequency sounds and introduced vibration in aquatic environments on a nanoscopic scale. It explores sound frequencies beyond the human range and the concepts of ultrasonic baths and sonoluminescence.
It is inspired by the photonic properties of diatoms and their potential vulnerability due to anthropogenic pressures. Diatoms are attracted to light and their internal structures reflect light. In a dialogue between sound and light (both essential forms of underwater communication), ICARUS explores these relationships in an experimental approach using ice structures.
Diatoms are unicellular microalgae present in all aquatic environments on earth.
This project is developed in collaboration with the scientist Johannes Goessling. Johannes´ research resolves around the photonic properties of the glass shells of diatoms. Some of the structures are very complex and unique with highly periodic pores.
ICARUS performance was presented at Sónar+D – Sónar 2022 Lisbon Festival.
Supported by Cesam, Temporada Cruzada Portugal França 2022, United Nations Oceans Decade.
The encasement of the cell in a silicate frustule compounded of two valves and corresponding girdle bands is a unique feature of the diatoms. Photonic structures in the frustule, i.e. pores and chambers on the micro- to the nanoscale, interact with electromagnetic radiation in the visible spectrum of light (Goessling 2017).
