A number of Leveloggers were deployed at this restoration site along the Hackensack River as a permit requirement to document tidal hydrology. Over the many months that the Leveloggers were deployed, heavy biofouling was observed on the Leveloggers. Continue Reading »
Because the goal of Leveloggers is to provide fluctuations in water pressure only, their data must be compensated for barometric effects. In order to achieve this, barometric pressure must be subtracted from the Levelogger readings to give actual water level data. Continue Reading »
Have you noticed a difference in raw water level (pressure) readings when comparing data recorded by the latest Levelogger Edge line versus previous models? Find out why. Continue Reading »
The program includes the use of the Solinst LTC Levelogger Junior to monitor changes in water level, temperature, and conductivity in rivers and streams. Conductivity readings provide a general indication of the water quality, while the water level and temperature readings may be used to provide background information when any spikes or significant changes in conductivity readings are noticed.

Vernal wetlands are temporary pools of water that fluctuate seasonally with complex hydrological processes. They receive inputs from precipitation, runoff, and subsurface flow, and are influenced by geology, soil, and climate. This creates a unique habitat for diverse flora, amphibians and insects, including some threatened and endangered species. Continue Reading »
James Sullivan, Staff Environmental Scientist with GeoTrans Inc., has been very satisfied with the use of Solinst instruments in a variety of groundwater monitoring projects: “The reliability of Solinst Water Level Meters is second to none when it comes to accuracy, precision and durability. In the groundwater field I have utilized several different types of water level… Continue Reading »
Over the last two years, researchers in the Department of Civil and Environmental Engineering at the University of Louisville have been conducting an extensive assessment on a stream in Oldham County, Kentucky. The stream, which can be classified as “headwater”, has a drainage area of about 2.8 square miles (7.2 square kilometers) at the upstream… Continue Reading »
Automatic Barometric Compensation Submersed Leveloggers measure total or absolute pressure (water column equivalent + barometric pressure). In order to accurately determine the true changes in water level only, barometric pressure fluctuations must be taken into account. The simplest method to accomplish this is by the use of a Barologger suspended above high water level in one well… Continue Reading »
As the Olympic torch is passed from our hands in Canada, huge efforts are underway for the 2012 Summer Olympics set to take place in London, England. In preparation for the games, a new Olympic Park is being constructed in Stratford, East London. In the works since 2005, the Park spans 500 acres and features… Continue Reading »
The Greenland Ice Sheet covers 80% of the Island of Greenland – it is the largest ice mass in the Northern Hemisphere. Therefore, it should be no surprise that it is suspected to be a key contributor to current and future global sea level rise, particularly as the earth’s temperature continues to increase. Satellite evidence… Continue Reading »
