Dataset landingpage: BioBasis Nuuk - Vegetation - NERO line NDVI

Dataset specification

  • Title: BioBasis Nuuk - Vegetation - NERO line NDVI
  • Description: The NERO line is a permanent vegetation transect crossing all the dominating vegetation types found in the study area. The progression in the vegetation greenness (Normalized Difference Vegetation Index; NDVI) is followed on the NERO line one to two times per month throughout the snowfree season. NDVI is measured by a Crop Circle Handheld System and scans are conducted by moving the sensor steadily forward (ca. 1 meter per second) approximately 75 cm above the vegetation. This results in a measuring footprint of approximately 10 x 45 m. For further details, please refer to the newest BioBasis manual available at the website. Vegetation:Vegetation BioBasis Nuuk:The BioBasis programme monitors the dynamics of organisms and biological processes in the terrestrial and limnic ecosystems at Zackenberg and Nuuk. The BioBasis programme plays a central role in the development and implementation of the Circumpolar Biodiversity Monitoring Programme (CBMP) http://www.caff.is/monitoring across the Arctic.
