Aquatic Greenhouse Gas Emissions in a Changing World

Dr. Tonya DelSontro 
Department F.-A. Forel for Environmental and Aquatic Science; Faculty of Science 
University of Geneva, Switzerland 

It is now widely known that inland waters (i.e., lakes, reservoirs and rivers) emit significant amounts of greenhouse gases (GHG; i.e., CO2, CH4, N2O) – one aspect of the role inland waters play in climate change and in the global carbon cycle.

Anthropogenic changes to inland water nutrient cycles: sky to sea

Dr. Taylor Maavara
Lawrence Berkeley National Laboratory 

Rivers are the great connectors of the freshwater cycle, providing essential services to humans and ecosystems, including drinking water, transportation channels, food security, waste assimilation, and water purification.

Deciphering spatio-temporal patterns and using reactive transport models to improve process and understanding 

Dr. Bhavna Arora, Energy Geosciences Division 
Lawrence Berkeley National Laboratory 

Reactive transport models (RTMs) are essential tools to address a broad range of environmental problems such as acid mine drainage, radionuclide contamination, climate change and water resources management. The role of RTMs has been expanding in recent years to quantify processes from bedrock to canopy and from pore to watershed scales. However, this expanding role of RTMs brings significant scientific challenges, such as incorporating heterogeneity in models given that data are sparse, multi-sourced and convoluted. In addition, predicting future ecosystem response is problematic because different spatio-temporal factors impact system behavior and need to be represented adequately in models.

Vital signs in the low energy microbial world: linking physiology to ecosystem function

Dr. Jacqueline Goordial
Bigelow Laboratory for Ocean Sciences, East Boothbay, Maine

Microorganisms are the most diverse and abundant lifeforms on Earth, but less than 1% have been cultured in the laboratory for study. Thus, our knowledge of the metabolic potential of the vast majority of microorganisms is based primarily on genomic and metagenomic sequencing. Compounding these unknowns is evidence that bacteria commonly exist in prolonged states of low metabolic activity or non-growth states in environmental settings. This gap in our knowledge necessitates uniting physiology and molecular microbiology to understand the roles that bacterial communities play in biogeochemical cycling and ecosystem function.

Defining the Intersection of Geology, Geochemistry and Microbiology in Hydrothermal Environments

Dr. Daniel Colman
Department of Microbiology and Immunology, Montana State University

Hydrothermal systems provide excellent model systems to deconvolute the dynamic interplay between geology and geochemistry and the ecology and evolution of microorganisms. Extensive geochemical variation exists in hydrothermal systems that sets the stage for an incredible amount of microbial taxonomic and functional biodiversity. Further, microorganisms inhabiting hydrothermal systems can have profound roles in shaping the geochemistry of their environments through geo-biological feedbacks resulting from biological transformations of inorganic and organic chemical constituents.

Building an Understanding of Ecohydrologic Process through Model-Data Fusion

Dr. James O. Knighton​
Biological & Environmental Engineering, Cornell University

Recent advances in ecohydrology have been facilitated by the parallel emergence of ecohydrological models, high resolution hydrologic datasets, and data analytic techniques. In this talk I will first examine the hypothesis of ecohydrological separation (i.e. the Two Water Worlds Hypothesis) from the perspective of physically-based models and high frequency soil water isotopic measurements along a hillslope.
