Monitoring Water Systems: Big Picture or Small Details? (2 of 2)

Caption

Number of discharge gauge records over time. The number of discharge gauges continuously increased up until 1980 in the Global Runoff Data Centre's archive and started a steady decline right around the time when climate change awareness started to rise. The real decline of the monitoring network is probably less severe, but remains largely unknown due to the long delay between the time of the observation and the reported data finding its way to the GRDC archive. This material relates to a paper that appeared in the August 14, 2015 issue of Science, published by AAAS. The paper, by B.M. Fekete at City University of New York in New York, NY, and colleagues was titled, 'Time for in situ renaissance.'
