Iara is made from 3 dimensional Lidar scans of the igapó flood plain Macacaricuia Eschweilera Trees, documented this year. The trees are approximately 1200 years old. This animation is created using 118 years of recorded flood pulse data provided by the platform HidroWeb operated by the Brazilian Agency of Waters .
This data shows an intensification of the hydrological cycle leading to an increase of maximum water levels and the amplitude of the water regime (maximum and minimum water levels), Over the last 118 years the mean annual water level has increased by 1m. The intensification of the hydrological cycle in the largest hydrobasin on Earth is caused by natural climate variability (mainly forcing by Atlantic and Pacific sea surface temperatures), but also anthropogenic forcing for example the increase of hydro dams. An increase of 1m is likely to lead to slow, but progressive, extinction of these microhabitats and force trees to occupy higher floodplain elevations.
In the artwork this data drives the movements of the camera, the editing of the perspectives and the soundscape, so that what you are seeing and hearing is generated from the annual flood water pulse and the native landscape of the tree.
The sound is made up of audio recordings made in 2019 in the Amazon, using contact microphones to hear the internal water movements of the tree as well as composition elements improvised by the data. The text is made as a collaboration between Invisible Flock and LABVERDE, an attempt to communicate and reflect more deeply on our relationship and our impacts on these habitats and these ancient trees.
