Description

Permafrost Carbon and Nitrogen Lab (CarLa) focuses its efforts on the characterization of carbon and nitrogen vulnerability in thawing permafrost as well as carbon and nitrogen quantification and paleo-environmental reconstruction. The following parameters are recorded: bulk total carbon and nitrogen, total organic carbon and lipid biomarkers.

EA - Elemental Analysis
Total Organic Carbon (TOC) analysis is a well-defined and commonly used methodology that measures the carbon content of dissolved and particulate organic matter present in water. Many water utilities monitor TOC to determine raw water quality or to evaluate the effectiveness of processes designed to remove organic carbon. Some wastewater utilities also employ TOC analysis to monitor the efficiency of the treatment process. In addition to these uses for TOC monitoring, measuring changes in TOC concentrations can be an effective "surrogate" for detecting contamination from organic compounds (e.g. petrochemicals, solvents, pesticides). Thus, while TOC analysis does not give specific information about the nature of the threat, identifying changes in TOC can be a good indicator of potential threats to a system.
