ABSTRACT:

The data file includes water stables isotope data (throughfall, seepage, bulk soil water, and xylem water), soil volumetric water content, soil matric potential, leaf water potential, and ecosystem-level transpiration estimates, from the 10-month drought and rainfall labelling experiment at the Biosphere 2 Tropical Rainforest Biome (B2-TRF) in 2014-2015.
Data are organized in the csv files:
• evaristo_b22014_transpiration – ecosystem-level, meteorologically derived evapotranspiration
• evaristo_b22014_lwp – leaf water potential
• evaristo_b22014_swp – soil water potential
• evaristo_b22014_vwc – soil vol. water content
• evaristo_b22014_isotopes_throughfall – throughfall stable isotopes
• evaristo_b22014_isotopes_seepage – seepage stable isotopes
• evaristo_b22014_isotopes_soil – bulk soil water stable isotopes
• evaristo_b22014_isotopes_xylem – xylem water stable isotopes

ABSTRACT:

Partial pressures of soil O2 and CO2 are being measured continuously by four Critical Zone Observatories (CZO) Calhoun, Catalina-Jemez, Luquillo and Susquehanna Shale Hills. Daily average values are computed from 15, 30 or 60 minute observations.

ABSTRACT:

The data file includes discharge and associated hydrochemical data for La Jara stream water and springs around Redondo Peak in the Valles Caldera Preserve, New Mexico, within the Jemez River Basin Critical Zone Observatory, collected from March 2010 to May 2013. Solute chemistry includes pH, temperature, dissolved inorganic and organic carbon, major cations and anions, and Ge for select samples.
