What are Biogeochemical Cycles?

31.0K
The most common elements in organic molecules, carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus, are only available in the ecosystem in limited amounts. Therefore, these nutrients must be recycled through both biotic and abiotic components of the ecosystem, in processes generally called biogeochemical cycles.

Main Methods:

  • Utilized Empirical Dynamic Modeling (EDM), a nonlinear and nonparametric data-driven approach.
  • Employed attractor reconstruction to overcome limitations of traditional statistical models.
  • Focused on predicting chlorophyll-a concentration, a critical parameter for HAB identification.

Main Results:

  • The EDM demonstrated exceptional performance in predicting chlorophyll-a concentrations.
  • The model successfully captured the complex, nonlinear dynamics of chlorophyll-a changes in Lake Erie.
  • Findings indicate EDM's suitability for forecasting HAB-related water quality parameters.

Conclusions:

  • Empirical Dynamic Modeling (EDM) is a powerful tool for predicting chlorophyll-a and forecasting HABs in Lake Erie.
