Abstract To manage water resources and forecast river flows, hydrologists seek to understand how moves from precipitation, through watersheds, into channels. However, we lack fundamental information on the spatial distribution physical controls global hydrologic processes. This is needed provide theoretical support for large-domain model simulations. Here, address this issue, present a global, searchable database of 400 research watersheds with published descriptions dominant flow pathways. knowledge synthesis approach leverages decades grant funding, fieldwork effort local expertise. We use test longstanding hypotheses about roles climate, biomes landforms in controlling show that aridity predicts depth pathways terrain predict prevalence lateral These new data search capabilities efficient hypothesis testing investigate emergent patterns relate landscape organization function.

CAMELS-Chem: augmenting CAMELS (Catchment Attributes and Meteorology for Large-sample Studies) with atmospheric and stream water chemistry data

Hydrology and earth system sciences, Год журнала: 2024, Номер 28(3), С. 611 - 630

Опубликована: Фев. 13, 2024

Abstract. Large sample datasets are transforming the catchment sciences, but there few off-the-shelf stream water chemistry with complementary atmospheric deposition, streamflow, meteorology, and physiographic attributes. The existing CAMELS (Catchment Attributes Meteorology for Large-sample Studies) dataset includes data on topography, climate, land cover, soil, geology across continental US. With CAMELS-Chem, we pair these attribute 516 catchments deposition from National Atmospheric Deposition Program instantaneous discharge US Geological Survey over period 1980 through 2018 in a relational database corresponding dataset. include 18 common constituents: Al, Ca, Cl, dissolved organic carbon, total HCO3, K, Mg, Na, N, NO3, oxygen, pH (field lab), Si, SO4, temperature. Annual loads concentrations hydrogen, NH4, inorganic Na. We demonstrate that CAMELS-Chem sampled effectively climates, seasons, discharges trend analysis highlight coincident sampling of constituents process-based understanding. To motivate their use by larger scientific community variety disciplines, show examples how publicly available can be applied to detection attribution, biogeochemical process understanding, new hypothesis generation via data-driven techniques.

Expanding the Spatial Reach and Human Impacts of Critical Zone Science

Earth s Future, Год журнала: 2024, Номер 12(3)

Опубликована: Март 1, 2024

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.

Abstract Coastal ecosystems are at the nexus of many high priority challenges in environmental sciences, including predicting influences compounding disturbances exacerbated by climate change on biogeochemical cycling. While research coastal science is fundamentally transdisciplinary—as drivers and ecological processes often span scientific domains—traditional place–based approaches still employed to understand ecosystems. We argue that a macrosystems perspective, integration across distributed sites, crucial how affect suggest grand challenge questions, such as advancing continental‐scale process understanding extreme events global change, will only be addressed using network‐of‐networks approach. identify specific ways existing efforts can maximize benefit multiple interested parties, where additional infrastructure investments might increase return‐on‐investment along coast, continental United States case study.

Опубликована: Янв. 23, 2025

Abstract. The Unsolved Problems in Hydrology (UPH) initiative has emphasized the need to establish networks of multi-decadal hydrological observatories gain a deep understanding complex hydrologic processes occurring within diverse environmental conditions. already existing monitoring infrastructures have provided an enormous amount hydrometeorological data, facilitating detailed insights into causal mechanisms processes, testing scientific theories and hypotheses, revelation physical laws governing catchment behavior. Yet, programs often produced limited outcomes due intermittent availability financial resources substantial efforts required operate conduct comparative studies advance previous findings. Recently, some initiatives emerged that aim coordinate data acquisition hypothesis facilitate efficient cross-site synthesis To this end, common vision practical management solutions be developed. This opinion paper provocatively discusses two potential endmembers future observatory (HO) network based on given hypothesized community budget: comprehensive set moderately instrumented or, alternatively, small number highly supersites. A sites would provide broad spatial coverage across major pedoclimatic regions by supporting lumped response (e.g., rainfall–runoff relationship, Budyko analysis) continental landscapes. However, moderate instrumentation at each site may hamper in-depth processes. In contrast, extensively research enable community-based experiments unprecedented manner, thereby deeper complex, non-linear modulated scale-dependent feedback multiscale spatiotemporal heterogeneity. Lumping proven effective strategy other geosciences, e.g., vessels oceanography drilling geology. On downside, limitation approach is few catchments will not representative all regions, necessitating consideration generalization issues. discussion relative merits limitations these visions regarding HOs presented build consensus optimal path for address UPH coming decades. final proposes integrating flexible strategy. Keywords: network, experimental catchments, synthesis, vs. exploratory science, unsolved problems hydrology, societal needs, technology advancements.

Abstract Critical Zone (CZ) scientists have advanced understanding of Earth's surface through process‐based research that quantifies water, energy, and mass fluxes in predominantly undisturbed systems. However, the CZ is being increasingly altered by humans climate land use change. Expanding scope science to include both human‐ non‐human controls on important for anthropogenic impacts processes ecosystem services. Here, we share perspectives from U.S.‐based, early career centered around broadening focus societally relevant a transdisciplinary framework. We call increased training methods collaboration opportunities across disciplines with stakeholders foster scientific community values alongside physical science. build existing frameworks highlighting need institutional support educate graduate students throughout processes. also graduate‐student‐led initiatives increase their own exposure activities such as transdisciplinary‐focused seminars symposiums, volunteering local conservation groups, participating internships outside academia.
