Daily reports from the NGRIP-camp - week 22
Monday, May 29th
|
| Daily life |
| Blue sky, temperatures between -28C during night and -20C at day time. |
| Science |
| The measurement of the electrical conductivity of the ice is now working,
and it is part of the daily measurements. This measurement can reveal an
annual cycle and volcanic eruptions in the ice. |
| Logistics |
| The roof in the old drill-trench had to be supported, since it is lowering
due to the weight of the new snow on top. |
Tuesday, May 30th
|
| Daily life |
| Today the temperature in all three trench's (drill-, logging-, and
science-trench) was measured to -24C. The temperature is slowly raising
due to all the activity and we are getting to a more "comfortable" level.
It can be quite tough to operate equipment in -30C, sometimes one needs
to grab small items, like skrews, with the bare fingers, and that's COLD! |
| Science |
|
| Logistics |
| There have been disturbances on the radio due to signals from ships
- although the closest coast is 300 km's away. |
Wednesday, May 31st
|
| Daily life |
| The weather is still nice, between -37C and -27C with a blue sky and
a little wind. |
| Science |
| The new CFA (continous flow analysis of chemical species in the ice)
has been tested. Processing and cutting of the ice is following the proposed
plan, and today 44.5 m's of core were handled. |

|
Thursday, June 1st
|
| Daily life |
| Another day with nice weather, although the wind was somewhat stronger
than yesterday. Although today was a holiday in many European countries
work continued as every day on the ice. |
| Science |
| The new CFA equipment is now part of the routine processing of the
core. A new saw had to be adjusted somewhat in order to prepare the samplas
for the CFA, so "only" 36.5 m's of ice were processed today. |

Friday, June 2nd
|
| Daily life |
|
| Science |
| The electrical conductivity measurement, the ECM today measured the
transition from the warm Holocene period into the last glacial period.
Drilling is now well within the glacial ice. |

Saturday, June 3rd
|
| Daily life |
|
| Science |
| Ice from the Younger Dryas period (a short cold spell within the transition
between the last glacial and the present interglacial) is now being processed. |
| Logistics |
|
Sunday, June 4th
|
| Daily life |
| We're approaching summer temperatures, max temperature today was -16C. |
