Exploring the Spatial Effects of Nitrogen Mobility on Plant Growth and Soil Organic Matter Accumulation Using the Coupled CLM-PFLOTRAN Biogeochemical Model at NGEE Arctic Intensive Study Sites in Barrow, AK

NGEE Arctic scientists simulate gradient-driven N nutrient mobility in 3D soil domain by CLM-PFLOTRAN model would be critical to spatial distribution of plant LAI growth and thus long-term soil organic matter stocks in the polygonal coastal tundra ecosystem... Read more...

Safety Training Requirements -- New April 9, 2015

NGEE-Arctic participants and collaborators must complete the required viewing of safety videos and reading of safety manuals to be approved for field and laboratory work at NGEE-Arctic facilities in Barrow, Alaska.  The annual review of the manuals has been completed and resulted in only minor changes to the manuals:

  • Both manuals were updated with additional contact information.

Participants and collaborators are strongly encouraged to complete all training requirements prior to travel because computers and internet connectivity are limited in Barrow.

Training materials are only available on the NGEE-Arctic project website (https://ngee-arctic.ornl.gov/content/ngee-safety).

Access to training materials requires NGEE-Arctic website login. After login, the Safety tab will appear.

  • ORNL participants may access Training Materials with their ORNL UCAMS login UID and PWD.
  • Other participants and collaborators may access Training Materials with their website UID and PWD.
    • If you are not a registered website user, please request an account (Login tab). You will receive e-mail notification with your account information.
    • Note that it may take 24 to 48 hours for your account to be established.

Upon successful completion of the training requirements you will receive e-mail notification from NGEE-Arctic Management that you are approved for field and laboratory work at the NGEE-Arctic facilities in Barrow.
