Details

The Extech Digital Psychrometer simultaneously displays % relative humidity, temperature, dew point, or wet bulb or probe temperature. The wet bulb measurements are made without slinging. The meter calculates T1-T2 differential (air temperature minus external probe temperature) using optional probe and T2-dew point. The unique sensor cap design twists to the closed position for protection during storage. Additional meter features include switchable °F/°C temperature, data hold, max/min readings, and automatic power off.

Weather Extremes Shaking Up Fouling Communities in Urban Estuaries

Marine fouling species may seem to be lowly creatures, situated toward the bottom of that portion of the food chain animals comprise. However, these filter-feeding invertebrates that make their homes on hard underwater substrates such as the hulls of ships are among some of the most successful invasive species. Their secret is simply their ability to latch onto human vehicles and survive. Now, new research on the fouling community in the San Francisco Bay indicates that a single wet winter and the change in salinity that high levels of precipitation bring can knock back the advance of these hearty creatures. Marine biologist Andrew Chang of the Smithsonian Environmental Research Center’s Tiburon, California branch published this new research in December of 2017.

Fragile Water Infrastructure, Often On the Verge of Collapse

Do you know what's in your water? How certain are you that it's safe? In mid-December 2017, researchers from across the United States specializing in various disciplines came together at the annual meeting of the Society for Risk Analysis to present reports on a range of problems in American water infrastructure. This plumbing safety research illuminates a disturbing litany of failures in water safety all over the country—but also highlights a commitment to fixing problems and taking a proactive approach to keeping water infrastructure safer. The Replacement Era In 2001, the American Water Works Association (AWWA) released a report entitled, “Dawn of the Replacement Era: Reinvesting in Drinking Water Infrastructure.

Lake Pontchartrain Basin Foundation Keeps Lake Clean

Through regular water sampling and community outreach, the Lake Pontchartrain Basin Foundation protects one of Louisiana’s important crabbing and water recreation sites. Located near New Orleans, Lake Pontchartrain is a 630-square-mile estuary open to the Gulf of Mexico. The lake drains 10,000 square miles of land. Because of its proximity to the Gulf, the lake is a mix of freshwater and seawater that is home to several species of aquatic life such as trout, redfish and crab. “There is a tremendous amount of fishing in the lake, both recreationally and commercially,” said Brady Skaggs, Ph.D., the water quality program manager for the foundation.  “Some of the best crabs you can get in Maryland come out of Lake Pontchartrain.
