Field-portable visible/near-infrared spectrophotometer for mapping soil carbon in Canada's ecosystems

我们需要一种野外便携式仪器，测量土壤剖面上可见光和近红外辐射的反射率。这种仪器被称为可见光/近红外(VIS/NIR)分光光度探头。这种探头可以准确地评估土壤中的碳含量，只需将探头插入土壤中即可使用。因为这台仪器可以免费快速测量土壤碳，它将使我们能够构建非常详细的北极、北方各省和农业生态系统的土壤碳地图。我们需要这样做，因为土壤碳在不同领域的差异相当大，使用传统技术获得准确的估计需要大量样本，这是昂贵和耗时的。相比之下，这个探测器将允许我们在一个下午完成几周的实验室分析工作。

We are requesting a field portable instrument that measures the reflectance of visible and near-infrared radiation down a soil profile. This instrument is called a visible/near-infrared (VIS/NIR) spectrophotometeric probe. This probe can accurately assess soil carbon contents in a soil and is used by simply inserting the probe into the soil. Because this instrument measures soil carbon very quickly and at no cost, it will allow us to construct very finely detailed maps of soil carbon in the Arctic, provincial Norths and agricultural ecosystem. We need to do this because soil carbon varies quite a bit across a field and getting a precise estimate using traditional techniques requires a large number of samples which are costly and time consuming. In contrast, this probe will allow us to do the work of a few weeks of laboratory analysis in an afternoon.
