  • The hand auger core has been drilled and ice is packed in boxes: Coffee time!<br /> <br /> Photo: Olivia Maselli
  • The hand auger is the simplest and lightest drill system, collecting 74 mm diameter core from the top 10 m of firn. It can be operated by one person and weights 80 kg.<br /> <br /> Photo: Antje Fitzner
  • Drilling with the hand auger is being prepared.<br /> <br /> Photo: Olivia Maselli
  • 2 km west of NEEM a 12 m long 3-inch core was drilled with the hand auger.<br /> <br /> Photo: Olivia Maselli
  • The freshly drilled core is likely to cover the last 25 years or so.<br /> <br /> Photo: Martin Leonhardt
  • Meridian - the new unmanned aircraft system, developed by the CReSIS University of Kansas, is designed to enable extensive remote sensing surveys over isolated areas of Greenland and Antarctica.
  • Mid July little brother (CReSIS UAV) departing from big brother (Skier 21). Removable wings makes it easy to transport, and the Meridian can be assembled in minimum time in the field.
  • With radar equipment mounted on the Meridian plane the Kansas UAV team performed several test flights producing some high quality radar data.
  • In Greenland the Meridian is to collect airborne remote sensing observations required to understand and to model rapidly changing outlet glaciers.
  • Meridian is toved by a skidoo to the carpenter garage used as hangar.
  • The Meridian weighs 1,100 lbs, has 26-foot wingspan, and a range of 950nm at the full 120 lbs payload capacity.
  • 3 km south of the NEEM camp a danish and german team carried out pit studies. <br /> <br /> Photo: Paul Vallelonga

  • The CFA team dug a pit with the purpose of updating the chemistry profile with the most recent samples.<br /> <br /> Photo: Catherine Ritz
