The TriOS NICO is a low-cost UV photometer for online measurement of nitrate in lakes/rivers, drinking water, and wastewater applications. The four detection channels enable a precise optical determination of nitrate by absorption, taking into account turbidity and organic substances that pose a problem for many products currently on the market. An internal temperature correction additionally increases stability of the measured values.
The NICO is compatible with the G2 interface box, allowing fast and easy configuration of the sensors using a web browser. The sensor can be easily integrated into existing process control systems and external data loggers using the native RS-485 Modbus RTU output, and the optional W55 wiper reduces maintenance intervals by cleaning the optics before each measurement.

San Francisco Bay’s Nutrient Phenomena
From the gold rushes to the birth of Silicon Valley, the San Francisco Bay Area is known for welcoming swaths of people looking for a new frontier of culture and natural beauty. It has had a front-row seat to some of America’s most rapid industrialization and population growth for the past 200 years and is now home to over seven million people. Tourism booms as people from all around the world come to see the iconic Golden Gate Bridge and the expansive bay that lies beneath. But the bay is not just for looks. It plays an essential role in supporting modern California living--and we are not just talking about surfing. 
 
 Water from every toilet flush, shower and load of laundry is treated and pumped back into the bay.

For as long as humans have inhabited Europe’s Atlantic coast, the ocean has been a great source of wonder and mystery. History is full of fascinating tales of epic endeavors, new discoveries of fearless explorers, fishing communities inextricably linked to the bounties of the sea, cultural interactions both peaceful and not, and voyages that went awry during monumental storms or simply due to bad luck. 
 
In the south of Spain, at the boundary between the Atlantic Ocean and the Mediterranean Sea, one such tale involves a long-lost merchant ship that went undiscovered from the 16th century until 1984. Believed to be carrying valuable goods from Italy, it sank just across from Gibraltar in the Algeciras Bay at a point called La Ballenera.
Read MoreStaying Within Budget: Carbon Planning
While we usually concern ourselves with budgeting money or time, we should be thinking about another type of budget: the carbon budget. The carbon budget refers to the amount of carbon exchange, especially carbon dioxide, allotted on an annual basis to prevent the earth from reaching an increase of 2-degrees Celsius all over the globe. If a 2 degree increase does occur, global warming effects are expected to be catastrophic and irreversible. 
 
In order to know how close we are to reaching the carbon budget, an extensive knowledge of types of carbon input and their magnitudes, as well as their fluctuations over time, is needed.
