A bird calls, a fish surfaces, a dandelion sheds its seeds in a gust of air. However, when events stretch out across hours, days and more, we no longer readily perceive, but rely on the labelling of such events as abstract groupings we “know” to be, yet have no visible delineation. 'Decohering Delineation' is the entanglement of neural networks and oceanic data as an experimental exploration of ways to make tangible, through the use of quantum computation and neural networks, the innate interconnected nature of ecosystems and specimens, artificial & natural. Neural networks normally cannot reproduce patterns outside of the data used to train them, but through the use of quantum circuits and marine data, the shifting regions of entanglement create spaces of external--internal influence, allowing patterns of Others to exist within them.
