Monitoring of flowing artesian conditions using Leveloggers can be quite straight forward. Continuous artesian conditions infer that the piezometric surface never drops below the level of the ground surface, or particularly the top of casing elevation, and the casing is sealed with a wellhead. In this case, where freezing is not a concern, the Levelogger need only be installed on the wellhead itself by means of an Artesian Well Fitting Assembly. This same fitting allows the use of a Direct Read Cable to install the Levelogger at depth in a well, for cases when the piezometric surface falls below top of casing.
When conducting artesian monitoring with Leveloggers, a number of issues should be considered. First, ensure that the maximum hydraulic pressure the datalogger will encounter at its installation point, will not exceed the specified range of the datalogger. Second, artesian conditions do not preclude the necessity for barometric compensation of Levelogger data. Artesian conditions are caused by aquacludes forming confined aquifers. Confined aquifers, while not acted on by barometric pressure to the same extent as unconfined aquifers, are typically subject to barometric pressure at some barometric efficiency. Finally, bear in mind that the total pressure and subsequent water column equivalent depth measured by the Levelogger after barometric compensation may not represent the actual water level within the artesian well. Sealed intermittent artesian wells can be pressurized when artesian, but can also be de-pressurized when non artesian. The Levelogger’s reading after barometric compensation represent the height of the piezometric surface.

The Charles River used to be a swimming hotspot for Cambridge and Boston residents.
Decades of industrial pollution and nutrient runoff have degraded water quality and eliminated public swimming in the Lower Charles, but a movement is afoot to get Boston and Cambridge back in the water. One step toward the goal of a safely swimmable river—without the need to obtain a permit, as is now necessary—is detecting and managing the harmful algal blooms that appear on the river.
An experimental floating wetland and new research and analysis of water quality data that shows a possible effective detection system for algal blooms on the Charles River are two new steps toward the goal of safe, accessible swimming.Read More
The Gulf Stream, the massive western boundary current off the east coast of North America, moves water from the Gulf of Mexico north and west across the Atlantic Ocean. There’s a lot of energy in that much moving water and researchers are trying to put it to use.
Although the Gulf Stream’s path shifts (researchers say it acts like a wiggling garden hose), in a couple of spots, it stays relatively stable. At one such spot off the coast of Cape Hatteras, North Carolina, researchers have dropped moorings and research instruments to study the current with the eventual goal of harnessing it for renewable energy.Read More
In early 2020, Michigan found itself facing one of the worst outbreaks of Covid-19 in the country. Though it’s close to second nature now, businesses, schools and governments were suddenly forced to conduct business without close contact. Universities and research institutions had to pause some scientific research. Whatever was able to continue slowed to a crawl.
Around the Great Lakes, a network of buoys monitors dozens of water quality parameters and lake conditions, reporting them in real time. This year, the monitoring season was cut a bit short as Covid-19 restrictions hit in the weeks before buoys were set to be deployed.Read More
