ABSTRACT:

*** This is the addendum version with updated fSi_diss ***
This resource contains accompanying stream water chemistry data (major cations, anions, DOC, Silicon, Germanium, and Silicon stable isotopes) presented in "Resiliency of silica export signatures when low order streams are subject to storm events" by Fernandez et al. The datasets represent seven storm events from six different catchments across the US, Canada, and France as part of an international cross-CZO collaboration supported through SAVI (Science Across Virtual Institutes).

Files are provided in ".csv" format and are organized both with respect to individual sites (listed below) and as bulk metadata (designated 'AllSites' ).

CZO sites and storm events investigated for this study (site specific csv file name identifier is provided inside the brackets [ ] ):
[LaJara] - La Jara Creek, Jemez CZO (New Mexico, USA) - March to Late May 2017 snowmelt event
[ProvidenceCreekP303] - Providence Creek Subcatchment P303, Southern Sierra CZO (California, USA) - January 2018 rain event
[ElderCreek] - Elder Creek, Eel River CZO (California, USA) - January 2017 rain event
[Sapine ] - Sapine Creek, OZCAR (Mont Lozère, FRA) - October 2016 rain event and long term monthly sampling from 2013-2015
[QuiockCreek] - Quiock Creek, OZCAR (Basse-Terre, Guadeloupe, FRA) - October 2015 rain event
[KwakshuaWatershed708] - Kwakshua Watershed 708, Hakai Institute (Calvert Island, British Columbia, CAN) - two rain events, September and October 2017

Site-specific lithology and associated chemical compositions used in calculations for fSi (proxy for fraction of Si remaining in solution) are provided in 'bedrock_compositions.xlsx'. Refer to the manuscript for further details.

ABSTRACT:

This resource contains accompanying riverine chemistry data (major cations and anions), discharge data and physiochemical parameters (conductivity, temperature and dissolved oxygen) presented in "Drought constrictions on lateral carbon transport" by Wang et al. The dataset is comprised of a 30-min frequency time series from 2021/08/20 to 2023/06/30 for the Upper Sangamon River obtained from a RiverLab deployment. The discharge data is obtained from USGS (https://waterdata.usgs.gov/nwis/). pH data are available in the accompanying manuscript Extended Data Table 1 and are obtained from the WQP (https://www.waterqualitydata.us/).

Files are provided in ".csv" format.

CZO site and time range reported in this study:
Sangamon River, IML-CZO (Illinois, USA) - August 20 2021 to June 30 2023

Site description and details of the RiverLab facility are available in the accompanying manuscript and in Wang et al. (2024) (https://doi.org/10.1016/j.scitotenv.2023.167379)
