Environmental variability and system heterogeneity in terrestrial biogeochemical models

Creator:

Sierra, Carlos Alberto

Abstract:

Ecosystems are highly heterogeneous systems subjected to important levels of environmental variability; however, it is common in terrestrial biogeochemical models to assume homogeneous properties of the elements of the system or constant environmental conditions. For some processes, heterogeneity in these models is treated very simplistically, but there is not much...

Interactions amongst Local and Global Drivers of Coastal Acidification in Estuarine Habitats of the Northern California Current

Creator:

Pacella, Stephen R.

Abstract:

The variability of coastal carbonate chemistry continues to provide significant hurdles for understanding interactions between anthropogenic and natural CO2 cycling and resultant effects on coastal acidification dynamics. Attribution of the anthropogenic component is vital for identifying the impacts of increasing atmospheric carbon on coastal habitats such as coral reefs, upwelling...
