The Delta Ray Road Trip
Attributing the source of CO2 presents challenges for environmental agencies and research institutions. CO2 isotope ratios carry information about the emitter. However, their continuous monitoring presents a complex task. The Thermo Scientific Delta Ray CO2 Isotope Ratio Infrared Spectrometer (IRIS) enables scientists to perform isotope ratio analysis directly where the sample is taken. On a road trip through Canada, the analyzer was installed in an RV and continuously monitored the CO2 concentrations, 13C and 18O isotope ratios coast to coast.
Introduction to Satellite and Aerial Spectral Imaging Systems
April 28th 2025Modern remote sensing technologies have evolved from coarse-resolution multispectral sensors like MODIS and MERIS to high-resolution, multi-band systems such as Sentinel-2 MSI, Landsat OLI, and UAV-mounted spectrometers. These advancements provide greater spectral and spatial detail, enabling precise monitoring of environmental, agricultural, and land-use dynamics.
The fNIRS Glossary Project: A Community-Sourced Glossary of Key Terms
April 28th 2025Established to develop a community-sourced glossary covering key functional near-infrared spectroscopy (fNIRS) terms, including those related to the continuous-wave (CW), frequency-domain (FD), and time-domain (TD) NIRS techniques, the fNIRS Glossary Project features over 300 terms categorized into six key domains: analysis, experimental design, hardware, neuroscience, mathematics, and physics. It also includes abbreviations, symbols, synonyms, references, alternative definitions, and figures where relevant.
