A new generation of environmental satellites, the Sentinels, has recently been launched by the European Space Agency. Part of ESA’s Copernicus Programme, the sentinel mission has adopted an Open Data policy which intends to make different levels of data freely available via an online data hub. Sentinel data will support applications including land monitoring, emergency management and security and will thus form the evidence-base for a wide-range of local, regional, national and international decisions, from individual insurance claims to humanitarian interventions. (...) By providing ever more data streams for monitoring and managing the planet, the sentinels institute a novel mode of visibility in terms of resolution, coverage and frequency. At the same time, they are co-constitutive of the increasing datafication of the environment. In the entwinement of heavenly gaze and data visions, I want to recover the work of ‘data fictions’ in order to demystify notions of visibility and calculability associated with “earth observation” and trouble its unquestioned pursuit of total monitoring.

Despite all the attention to Big Data and the claims that it represents a “paradigm shift” in science, we lack understanding about what are the qualities of Big Data that may contribute to this revolutionary impact. In this paper, we look beyond the quantitative aspects of Big Data and examine it from a sociotechnical perspective. We argue that a key factor that distinguishes “Big Data” from “lots of data” lies in changes to the traditional, well-established “control zones” that facilitated clear (...) provenance of scientific data, thereby ensuring data integrity and providing the foundation for credible science. The breakdown of these control zones is a consequence of the manner in which our network technology and culture enable and encourage open, anonymous sharing of information, participation regardless of expertise, and collaboration across geographic, disciplinary, and institutional barriers. We are left with the conundrum—how to reap the benefits of Big Data while re-creating a trust fabric and an accountable chain of responsibility that make credible science possible. (shrink)

This article provides an overview of the analysis of technological zones. A technological zone can be understood as a space within which differences between technical practices, procedures and forms have been reduced, or common standards have been established. Such technological zones take broadly one of three forms: (1) metrological zones associated with the development of common forms of measurement; (2) infrastructural zones associated with the creation of common connection standards; and (3) zones of qualification which come into being when objects (...) and practices are assessed according to common standards and criteria. The article argues that technological zones can have more or less clear borders, but such borders increasingly do not correspond to the borders of nation-states. Through a discussion of the global oil industry, some of the ways in which the formation of technological zones has become critical to contemporary economic and political life are examined. (shrink)
