Abstract Two major barriers hinder the holistic understanding of subsurface critical zone (CZ) evolution and its impacts: (a) an inability to measure, define, share information (b) a societal structure that inhibits inclusivity creativity. In contrast aboveground portion CZ, which is visible measurable, bottom boundary difficult access quantify. context these barriers, we aim expand spatial reach CZ by highlighting existing effective tools for research as well “human reach” science expanding who performs such it benefits. We do so exploring diversity vocabularies techniques used in relevant disciplines, defining terminology, prioritizing questions can be addressed. Specifically, explore geochemical, geomorphological, geophysical, ecological measurements modeling estimate base thickness. also outline importance approaches developing diverse workforce looks like harnesses creativity society serves, addressing historical legacies exclusion. Looking forward, suggest grow science, must broaden physical spaces studied their relationships with inhabitants, measure “deep” make data accessible, address bottlenecks scaling data‐model integration. What needed—and what have tried outline—are common fundamental structures applied anywhere researchers involved investigating recording processes from myriad perspectives.

Concentration-discharge (CQ) relations are commonly used to understand geochemical and hydrologic controls on the generation of solutes in watersheds. Despite widespread application CQ relations, this technique has been infrequently applied acid mine drainage (AMD) sites, but framework may allow mechanistic understanding remedial outcomes such as impoundment water within underground mines. Results analyses changes metal loads an AMD affected watershed Colorado, USA indicate that dissolved increased at many individual locations following workings. Although were observed most locations, these increases offset by a large decrease loading from largest mine. A analysis included data instream monitoring location showed statistically significant Fe Zn after bulkhead emplacement, indicating net positive effect bulkheads. Streams generally displayed dilution patterns whereas mines springs either flushing or chemostatic prior bulkheading, which transitioned transition dynamic equilibrium processes. Saturation indices for sulfide secondary minerals indicated near phases including schwertmannite, fluorite, gypsum. vary through time suggesting progressive leaching mass available workings decreases. Together, diverse provide integrated variability solute generating processes inform remediation plans similarly sites nature mineralogic quality.
