Field biologists and ecologists are starting to open new avenues ofinquiry at greater spatial and temporal resolution,allowing them to “observe the unobservable”through the use ofwireless sensor networks.Sensor networks facilitate the collection ofdiverse types ofdata (from temperature to imagery and sound) at frequent intervals—even multiple times per second—over large areas,allowing ecologists and field biologists to engage in intensive and expansive sampling and to unobtrusively collect new types ofdata.Moreover,real-time data flows allow researchers to react rapidly to events,thus extending the laboratory to the field.We review some existing uses ofwireless sensor networks,identify possible areas ofapplication, and review the underlying technologies in the hope ofstimulating additional use ofthis promising technology to address the grand challenges of environmental science.
