The Global River Discharge (RivDIS) data set contains monthly discharge measurements for 1018 stations located throughout the world. The period of record varies widely from station to station, with a mean of 21.5 years. These data were digitized from published UNESCO archives by Charles Voromarty, Balaze Fekete, and B.A. Tucker of the Complex Systems Research Center (CSRC) at the University of New Hampshire. River discharge is typically measured through the use of a rating curve that relates local water level height to discharge. This rating curve is used to estimate discharge from the observed water level. The rating curves are periodically rechecked and recalibrated through on-site measurement of discharge and river stage.

We have isolated the plasma membrane H+−ATPase in a phosphorylated form from spinach (Spinacia oleracea L.) leaf tissue incubated with fusicoccin, a fungal toxin that induces irreversible binding of 14–3–3 protein to the C terminus of the H+-ATPase, thus activating H+ pumping. We have identified threonine-948, the second residue from the C-terminal end of the H+-ATPase, as the phosphorylated amino acid. Turnover of the phosphate group of phosphothreonine-948 was inhibited by 14–3–3 binding, suggesting that this residue may form part of a binding motif for 14–3–3. This is the first identification to our knowledge of an in vivo phosphorylation site in the plant plasma membrane H+-ATPase.
