Abstract. The magnetic signature of an urban environment is investigated using a geographically distributed network of fluxgate magnetometers deployed in and around Berkeley, California. The system hardware and software are described and initial operations of the network are reported. The sensors measure vector magnetic fields at a 3960 Hz sample rate and are sensitive to 0.1 nT/Hz. Data from individual stations are synchronized to ±120 µs using global positioning system (GPS) and computer system clocks and automatically uploaded to a central server. We present the initial observations of the network and preliminary efforts to correlate sensors. A wavelet analysis is used to study observations of the urban magnetic field over a wide range of temporal scales. The Bay Area Rapid Transit (BART) is identified as the dominant signal in our observations, exhibiting aspects of both broadband noise and coherent periodic features. Significant differences are observed in both day–night and weekend–weekday signatures. A superposed epoch analysis is used to study and extract the BART signal.

Abstract. The magnetic signature of an urban environment is investigated using a geographically distributed network of fluxgate magnetometers deployed in and around Berkeley, California. The system hardware and software are described and initial operations of the network are reported. The sensors measure vector magnetic fields at a 3,960 Hz sample rate and are sensitive to 0.1 nT / √Hz. Data from individual stations are synchronized to ± 120 μs using GPS and computer system clocks and automatically uploaded to a central server. We present the initial observations of the network as well as preliminary efforts to correlate sensors. A wavelet analysis is used to study observations of the urban magnetic field over a wide range of temporal scales. The Bay Area Rapid Transit (BART) is identified as dominant signal in our observations, exhibiting both aspects of broadband noise and coherent periodic features. Significant differences are observed in both day/night and weekend/weekday signatures. A superposed epoch analysis is used to study and extract the BART signal.

Social Geographies

The Centro de Documentación e Investigación (CDI) is an online archive which provides free access to over 20 collections on Peru’s internal armed conflict (1980–2000), a conflict which was distinctly shaped by racial and social inequalities. The digital nature of the archive is presented as an opportunity for democratising access to these historical sources and for promoting commemoration as a means of cultural reconciliation. However, there is a risk that pre-existing social geographies and material concerns will mean that the CDI replicates offline exclusions. This article argues that, whilst the CDI has made these documents accessible to a broader geographical audience, usage of the digital archive is still largely mediated through social hierarchies. Through its online archive and offline engagement activities, the CDI appears to have generated a more geographically distributed network of content producers, but one which remains biased towards university-educated participants in urban areas.

Listening, a significant dimension of the behavior of hearing-impaired children, may be measured directly by recording childrens' responses to obtain audio narrations programmed via a conjugate reinforcement system. Twelve hearing-impaired, school-aged children responded in varying ways to the opportunity to listen. Direct and continuous measurement of listening has relevance for evaluation of remediation methods and for discovery of variables potentially related to listening.
