Bringing together media studies and environmental humanities, the contributors to Saturation develop saturation as a heuristic to analyze phenomena in which the elements involved are difficult or impossible to separate. In ordinary language, saturation describes the condition of being thoroughly soaked, while in chemistry it is the threshold at which something can be maximally dissolved or absorbed in a solution. Contributors to this collection expand notions of saturation beyond water to consider saturation in sound, infrastructure, media, Big Data, capitalism, and visual culture. Essays include analyses of the thresholds of HIV detectability in bloodwork, militarism's saturation of oceans, and the deleterious effects of the saturation of cellphone and wi-fi signals into the human body. By channeling saturation to explore the relationship between media, the environment, technology, capital, and the legacies of settler colonialism, Saturation illuminates how elements, the natural world, and anthropogenic infrastructures, politics, and processes exist in and through each other.

From the late nineteenth through most of the twentieth century, the evangelical Protestant Grenfell Mission in Newfoundland and Labrador, Canada, created a network of hospitals, schools, orphanages, stores, and industries with the goal of bringing health and organized society to settler fisherfolk and Indigenous populations. This infrastructure also served to support resource extraction of fisheries off Labrador's coast. In Slow Disturbance Rafico Ruiz engages with the Grenfell Mission to theorize how settler colonialism establishes itself through what he calls infrastructural mediation—the ways in which colonial lifeworlds, subjectivities, and affects come into being through the creation and maintenance of infrastructures. Drawing on archival documents, maps, interviews with municipal officials, teachers, and residents, as well as his field photography, Ruiz shows how the mission's infrastructural mediation—from its attempts to restructure the local economy to the aerial surveying and mapping of the coastline—responded to the colony's environmental conditions in ways that expanded the bounds of the settler frontier. By tracing the mission's history and the mechanisms that enabled its functioning, Ruiz complicates understandings of mediation and infrastructure while expanding current debates surrounding settler colonialism and extractive capitalism.
