Our Science Goal: The Age of Water and Carbon

Organic team science would enable the creation of “virtual overlay networks” over existing cyberinfrastructure and other related activities.

This study focuses on long-standing problems of coupled water and carbon budgets through development of a new scientific paradigm, The Age of Water and Carbon, that melds theory and practice from limnology and hydrology within the paradigm of Organic Data Science. We are integrating analytical frameworks from two communities – hydrology and isotope modeling in Critical Zone Observatories (CZOs) and hydrodynamic water quality modeling from the Global Lake Ecological Observatory Network (GLEON) – to quantify water and material fluxes from two research sites, the Shales Hills CZO and the GLEON member site, North Temperate Lakes LTER. This foundation will serve as a nexus for participation by multiple communities and will seed the growth of additional science through shared ideas, knowledge, and data.

An initial goal is a retrospective analysis based on a fully-coupled catchment-lake-groundwater hydrodynamic model parameterized from national data, calibrated with local data, and implemented to run climate and landuse change scenarios. The target catchments for the initial catchment-lake isoscapes are Trout Lake (Wisconsin) and Shaver Creek (Pennsylvania). As water age and the associated flowpaths are identified, scientists will use that information to infer the sources of organic carbon to lake-catchment ecosystems, their fluxes from the landscape to lakes, the fates as storage, conversion or export, and understanding of the uncertainties surrounding these quantities. Thus, an outcome of this work will be the first-ever dynamical model for lake water, energy and carbon cycling constrained by a fully coupled catchment mass balance including the effects of the groundwater basin.

Models Employed

Catchment: Penn State Integrated Hydrologic Model (PIHM)
Lake: General Lake Model (GLM)

The Online Framework

The science-driven demands of this research project have motivated the assembly of community-level resources distributed amongst institutions. The complex suite of resources, including data sets, computer models, computing resources, or technological staff must be coordinated and directed toward a common goal.

The organic data science platform is a structured environment that can handle this complexity. By documenting the scientific progress, unresolved tasks that must be undertaken are made clear, both as a reminder to the principal investigators, but also to new members who want to contribute. The wiki provides a legacy of documentation, and a trail of how results were obtained. Ultimately, it is envisioned to lead to better scientific products representative of diverse contributions from both the hydrology and limnology communities.
