Introduction: Aim | Scope

Aim:

Cyclic climate proxy data--or "cyclostratigraphy" -- linked to deterministic forcing mechanisms offer important age controls for the geological time scale. For convenience, such data will be considered to have recorded "climate cycles." A principal forcing mechanism that drives climate cycles is insolation, which is modulated by Earth's orbital-rotational dynamics and orientation relative to the Sun (see Cyclostratigraphic Drivers).

Climate cycles are based upon interpretations of cyclic patterns observed in time-dependent climate proxy series. The validity of such interpretations depends on:

      the fidelity of the proxy in representing a climate process
      the stratigraphic completeness of the proxy
      the response of climate to forcing
      the presence of independent time controls.
The interpretations rely on exploring the above issues through creative application of quantitative analysis and modeling. Therefore a major goal is to build and maintain browser-facilitated visualization and analysis tools for public access (see Toolbox), and to provide an online laboratory for users to interact easily with the greater CHRONOS system (see Laboratory).
