  • What is the purpose of soil boring and borehole logging?

    What is the purpose of soil boring? Soil boring is a practice of geotechnical investigations whose purpose is to determine the soils load-bearing capabilities, water table and chemical contamination.  Boring is important because (1) it helps to determine the capacity of the soil to provide support to the structures on the surface, (2) it reveals the permeability of the soil ...

  • How much data is enough data?

    Short answer: it depends on the application and how the data is going to be used.  However, in many ways it boils down to context… For instance, in relation to climate change, if we look at global mean air temperature, it would be very difficult to assess any level of change over time if we did not have a collection of data in a time-series. ...
