The The Solinst Model 615S shielded drive-point piezometer has a stainless steel, 50 mesh cylindrical filter-screen, within a 3/4" (20 mm) stainless steel drive-point body, screen support and a barbed fitting for attachment of sample tubing. Optional heavy-duty extension couplings are also available to create a strengthened and more rugged piezometer.
The inner barbed fitting allows connection of 5/8" OD x 1/2" ID (16 mm x 12 mm) LDPE or Teflon sample tubing. This prevents sample water from contacting the steel extension rods, and maintains high sample integrity, even when inexpensive carbon steel extensions are used.

New map shows significant groundwater depletion in Central California
Groundwater level data collected by a Central California county shows significant drops during the past 12 years, according to a San Luis Obispo Tribune article. 
 Data shows that groundwater has dropped by a minimum of 70 feet from 1997 to 2009 in the Paso Robles area of Central California. 
 In the past four years the areas of most significant decline have expanded north and south. 
 Drought and agricultural withdrawals are the likely culprits for the groundwater decline. 
Some advocates are calling for more responsible water use by vineyards in the area, while farmers note that the recent drought did not help the situation.

Anyone who has spent a significant amount of time in nature can likely relate to feeling connected and defensive toward protecting the environment. Heather Kinney, a coastal restoration scientist with The Nature Conservancy in Rhode Island, knows this feeling well, having felt a deep connection to nature her entire life. “I have always had a deep love for nature and the environment, particularly being out on the water and being drawn to the ocean, as cliché as that sounds,” says Kinney. 
 
Being so close to nature her entire life led Kinney to pursue a career in conservation and restoration. “You want to protect what you love, and I think that once I fell in love with it- it was something that I wanted to be able to pursue professionally,” she explains.
Read MoreNot So Quiet Polar Night: Arctic Creatures Found to be Active During Dark Part of the Year
Most people need little more than a comfortable pillow, a blanket, and a dark room to drift off into a multi-hour snooze. Many researchers assumed that once plunged into darkness for about half the year during the polar night, most polar creatures would do the same: fall asleep and take a big nap for as long as the darkness lasted. But Jon Cohen, associate professor of marine sciences, school of marine science and policy, in the College of Earth, Ocean, and the Environment at the University of Delaware, wondered if that was true. Despite the technical challenges of monitoring biota in very low light conditions, Cohen and his team were determined to find out if krill, copepods, and other creatures were dozing off in the dark or seeking out prey, light, and each other.
