Accurate quantification of alkalinity export from the near-field zone remains a key bottleneck for monitoring, reporting, and verification (MRV) of carbon dioxide removal (CDR) through Enhanced Weathering (EW). Here the authors validate the Everest Pulsar, a field-deployable alkalinity sensor that accumulates total alkalinity (TA) using a weak acid ion-exchange resin and transduces resin saturation into a digital, in situ measurement.
