9 years ago Conclusion at meeting. Investigate registering time series as CUAHSI data sets, or a WFS for sites with list of variables (site catalog), harvest into pipeline for CINERGI. Ilya, @smrazgs look at a sampling feature WFS for CUHASI samples to find those with chem data Bernard is domain point guy.
Capability: chained search to delve into data set. Seamless access from catalog to data through chained search.
A very basic use case is the gathering of information on major dissolved anion (SO4, Cl, Br, HCO3) and cation (Ca, Mg, Na, K) concentrations for rivers at a location close to the coast just outside the tidal influence. In order to make the data useful, the date (time) of sampling, pH, location, filtration cutoff, storage/preservation, lab location, analytical method and detection limit should be available. I am not aware of any system that would allow to retrieve such information for the major rivers of the world (say to top 50-100 rivers by water flux). This information, ideally complemented with water discharge, strontium (or even lithium) concentrations and 87Sr/86Sr isotope data, could be used to reassess the uptake of carbon dioxide by mineral weathering reactions in the respective drainage basins.
