		<title>Will the US Geological Survey Go Metric?</title>
		<description><![CDATA[I was asked the other day if I thought that the USGS would ever go metric. I am unqualified to answer this question but I care about the implications of the issue. I started my field career working in Imperial units (also known as English) before the Water Survey of Canada converted to the International System of units (SI, commonly known as metric) in 1980 so I have a firsthand experience with the process and believe it would be much easier now with the advantage of modern electronic technology. In order to coordinate data sources to tackle the ‘wicked’ 21st &#8230; <a href="http://www.aquaticinformatics.com/blog/will-usgs-go-metric/"><span class="readmore">Read More</span></a>]]></description>

		<title>Do you have enough bananas?</title>
		<description><![CDATA[The rejuvenation of the hydrometric workforce is apparent everywhere I look. The bi-modal demographic of pre-retirees and new recruits is rapidly changing to a positive-skew, long tail, age distribution. This is both exciting and worrisome. The long tail of experienced veterans is continually getting shorter. What is left is a cadre of (mostly) young, very smart, capable, well-educated and enthusiastic stream hydrographers. This transition is very timely given the rapid changes in hydrometric  monitoring technology (e.g. ADCP). The implementation of new technology is actually driving some old field hands to choose to retire. They simply aren’t interested in learning how &#8230; <a href="http://www.aquaticinformatics.com/blog/monkey-bananas/"><span class="readmore">Read More</span></a>]]></description>

		<title>A New Frontier &#8211; Rating Curves from Space?</title>
		<description><![CDATA[Early in my career, frequent field visits were necessary to wind the recorder clock; flush the intakes; replace the paper chart; and keep the pen ink reservoir full. Modern gauging technology is much more reliable so the requirement for frequent field visits is primarily to obtain rating measurements. Station health can be monitored remotely; data are communicated in real-time; and solid state electronics require little maintenance resulting in little need for regularly scheduled field visits. What is needed now is some way to reduce our reliance on brute force methods for rating curve calibration and validation. Nathanson et al. (2012) &#8230; <a href="http://www.aquaticinformatics.com/blog/rating-curves-from-space/"><span class="readmore">Read More</span></a>]]></description>

		<title>Real or Not? Discharge as a Virtual Variable</title>
		<description><![CDATA[Discharge is such a great variable It is so rich in information about everything that has happened upstream and so informative about what will be happening downstream. The dynamics of streamflow are tightly linked to both ecosystem function and economic viability. If only discharge data were real. Beven and Westerberg (2011) argue that “some periods of hydrological data are disinformative in trying to make models as hypotheses about catchment response…”. It is difficult to counter this argument in light of studies such as Jonsson et al. (2002). Two gauging stations in each of five Nordic countries were selected and all &#8230; <a href="http://www.aquaticinformatics.com/blog/discharge-virtual-variable/"><span class="readmore">Read More</span></a>]]></description>

		<title>Virtual Observatories and Snakes in the Grass</title>
		<description><![CDATA[I ended my last post “Amazing GRACE” with a segue to virtual observatories with a call to “… start thinking about our methods of measurement and data management to figure how to combine what remote sensing does well (extensive coverage) with what field observations do well (high resolution).” Virtual observatories are a blend of the things that we observe with the things that we predict, or assume, to be true. The things that we predict, or assume, to be true are derivatives of observational systems. There are many sources of satellite remote sensing information and almost all of these products &#8230; <a href="http://www.aquaticinformatics.com/blog/virtualobservatories/"><span class="readmore">Read More</span></a>]]></description>

		<title>Amazing GRACE &#8211; Groundwater from Space and the Future of Hydrometry</title>
		<description><![CDATA[Gravity Recovery and Climate Experiment Mission (GRACE) data is being streamed to Time Square in New York City until April 22nd in honor of World Water Day. If you haven’t heard about GRACE, you should check it out http://www.csr.utexas.edu/grace/. The earth is a closed system so when water leaves one region it will appear somewhere else.  The twin GRACE satellites, which have been in a paired orbit for 10 years, measure their distance relative to each other using laser beams. This distance changes as the satellites pass over anomalies in the mass of the earth, allowing for the mapping of &#8230; <a href="http://www.aquaticinformatics.com/blog/groundwater-from-space/"><span class="readmore">Read More</span></a>]]></description>

		<title>Is Rock Snot Affecting Your Rating Curve?</title>
		<description><![CDATA[Didymosphenia geminata is a freshwater alga that forms extensive blooms on rocky stream beds. The common name for Didymo is ‘Rock Snot’. The common name is very descriptive of small quantities but I think that extensive blooms look more like a raw sewage spill. Long plumes of the brown mats will bleach white giving the appearance of strands of toilet paper trailing from a septic sludge. Didymo is a northern circumpolar species preferring cold, clear water. It is spreading rapidly with the primary mode of dispersion suspected to be contaminated fishing/wading gear. It is a problematic invasive species because it’s &#8230; <a href="http://www.aquaticinformatics.com/blog/rating-curves-rock-snot/"><span class="readmore">Read More</span></a>]]></description>

		<title>MDG 2012 &#8211; World Meets Clean Water Goal Ahead of Time</title>
		<description><![CDATA[One of several, ambitious, Millennium Development Goals adopted by the World Health Organization and UNICEF in 1990 was to reduce, by half, the proportion of people without sustainable access to safe drinking water and basic sanitation by 2015. This specific target was achieved in 2010, five years ahead of schedule as recently reported in “Progress on Drinking Water and Sanitation 2012”. Specifically, since 1990 2 billion people have gained access to improved drinking water resources. Much of the gain has been achieved in China, where the economy has been thriving, providing the resources to develop basic infrastructure in rural areas. &#8230; <a href="http://www.aquaticinformatics.com/blog/millennium-development-goals/"><span class="readmore">Read More</span></a>]]></description>

		<title>Part 2 &#8211; World Water Day: The World is Hungry Because it is Thirsty</title>
		<description><![CDATA[In 2001 and 2002 the Rio Grande, draining one of the largest watersheds in North America, failed to produce enough flow to reach the Gulf of Mexico. &#124;  Photograph by Jack Dykinga. The theme of the 2012 World Water Day is “Water and Food Security”. The tag line is that “the world is hungry because it is thirsty”. The provision of safe and secure food to supply the needs of a growing population is inextricably linked to management of our fresh water resources. Our ability to manage the supply of water is, in turn, linked to our ability to measure &#8230; <a href="http://www.aquaticinformatics.com/blog/part-2-world-water-day/"><span class="readmore">Read More</span></a>]]></description>

		<title>Part 1 &#8211; World Water Day: Food and Water Security</title>
		<description><![CDATA[World Water Day is on March 22 The theme for World Water Day this year is “Water and Food Security”. The www.unwater.org/worldwaterday website provides a lot of interesting information about the importance of water for feeding a growing population that I would like to talk about. First, I would like to invert the World Water Day theme and talk about “Food and Water Security”. This animation of the water cycle provided on the UN world water day website demonstrates watershed function very clearly as an integrated system. This, however, is not how we manage our water resources.
