  REU Site: Earth Systems Research for Environmental Solutions, Descrição: Biosphere 2 Earth Systems Research for Environmental Solutions (B2-REU) gives students the opportunity to conduct interdisciplinary environmental and Earth systems science research and connect their work to existing environmental challenges and solutions, thereby increasing research relevance and student motivation. This 10-week summer REU site will foster the scientific career development of students coming from groups underrepresented in science, including minority and 1st generation students, and undergraduate students from universities with limited research opportunities. The B2 setting, along with nearby field sites and support laboratories, provides a unique environment to excite students about research and future careers in science, while the strong team of faculty mentors ensures that students are exposed to state-of-the-art research, learn current techniques, and create important connections in the scientific community. To complement the research, students participate in weekly research-seminar discussions with University of Arizona scientists; professional development activities, such as public speaking and graduate school workshops; and outreach training. Students learn to communicate their research to the thousands of B2 visitors. The summer culminates in a student undergraduate research symposium. Students are also supported to share with the scientific community by presenting at a professional meeting of their choice following the summer experience.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Antonio Alves Meira Neto - Integrante / Aditi Sengupta - Integrante / WANG, YADI - Integrante / DONTSOVA, KATERINA - Coordenador / Till H.

  Collaborative Research: Hillslope hydrology under glass: Controlled experimental testing of hillslope-scale hydrologic transport theories at Biosphere2, Descrição: The transport of solutes through hillslopes and watersheds is difficult to predict due to the complexity of the landscape and the processes controlling flow and transport. The current approaches use process descriptions derived from observations at small scales to make predictions at much larger scales, using effective values of the scale dependent parameters. However, this paradigm is known to be flawed, as in many cases the parameters cannot be measured or predicted easily. Increasingly frequent calls have been made for new theories that better link large-scale predictions to observable properties of the landscape. A new theoretical framework has recently been developed to represent solute transport at hillslope and watershed scales. However the framework is incomplete as a key element, the "age functions", is not specified from theory and must be investigated empirically. These functions characterize how the water leaving the system is selected from the distribution of water of different ages within the system. If these age functions could be parameterized from available landscape data, this framework would provide a rigorous alternative for modeling transport at hillslope and watershed scales that circumvents some of the scale-related challenges other methods face. This project will use the new Landscape Evolution Observatory (LEO) research facility at Biosphere2 to directly observe the shape of these age functions at a hillslope scale using a novel set of tracer experiments. This facility can be used to create precisely controlled and replicated flow and transport phenomena in three 330 m2 artificial hillslopes, and observe them with an unprecedented spatial and temporal resolution with over 1,500 sensors and 500 soil water samplers. A carefully designed sequence of experiments using stable water isotope tracers will be used to directly measure these age functions and relate their properties to the structure of flow paths using a novel experimental procedure entitled PERTH (PERiodic Tracer Hierarchy), developed specifically for this purpose. This project has four goals: 1) to make direct measurements of the age function in the LEO; 2) to use an integrated modeling approach to understand the relationship between the age function and underlying hillslope structure, and generalize the empirical findings to a broader class of landscape units 3) to test a series of hypotheses about the controls on the age function that pave the way towards an operational theory; and 4) to propose and test functional forms of the age functions that can be encoded in operational models of watershed-scale transport. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (3) / Doutorado: (4) . , Integrantes: Antonio Alves Meira Neto - Integrante / WANG, YADI - Integrante / Till H.

  COLLABORATIVE RESEARCH: COUPLED HYDROLOGICAL AND GEOCHEMICAL PROCESS EVOLUTION AT THE LANDSCAPE EVOLUTION OBSERVATORY, Descrição: The physical, chemical and biological structures and processes controlling biogeochemical reaction, flow and transport in natural landscapes interact at multiple space and time scales and are difficult to quantify. The current paradigm of hydrological and biogeochemical theory is that process descriptions derived from observations at small scales can be applied to predict at much larger scales, as long as some effective values of the scale dependent parameters can be identified. However, this paradigm is known to be flawed and increasingly frequent calls have been made for new theories that will better link small-scale process understanding with large-scale predictions. Furthermore, natural systems evolve in time in a way that is hard to observe in short-run laboratory experiments or in natural landscapes with unknown initial conditions and time-variant forcing. This project will use carefully designed wetting and drying experiments using stable water isotope tracers at the hillslope scale to determine the structure of flow paths, as well as to quantify water transit time distributions along those flow paths. Chemical analysis of pore waters and hillslope outflow will determine mineral weathering kinetics during these wetting-drying cycles which will be related to observed water transit times. Detailed numerical modeling with a coupled systems model will be used to simulate the flow and reactive transport and the evolution of the porous medium through data assimilation and inverse modeling. This project will observe the way water, rock and life interact and create the organized structure of the soil. These observations will be made at an unprecedented spatial and temporal resolution using the Landscape Evolution Observatory (LEO) at Biosphere 2. LEO consists of three large artificial landscapes built in a climate controlled environment that contain over 1,800 sensors to measure how water flows through these landscapes and interacts with the soil minerals and microbiological ecosystems. The research outcome will contribute to a new generation of modeling tools for quantifying contaminant transport in a changing environment. The result will reconcile the discrepancies between observations of flow and transport phenomena at lab and field scales. Two PhD students and several undergraduate students will be trained in novel hydrologic-geochemical experimentation and Earth systems modeling, and their research will be shared with the 100,000 people that visit Biosphere 2 each year.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (4) / Doutorado: (4) . , Integrantes: Antonio Alves Meira Neto - Integrante / TROCH, PETER A. - Coordenador / Katerina DOntsova - Integrante / Jon Chorover - Integrante / Guo-Yue Niu - Integrante., Financiador(es): National Science Foundation - Auxílio financeiro.
