ON NOVEMBER 21, WE FINISHED COLLECTING SEISMIC DATA!!!!
WE HAD COLLECTED DATA AT 473 HOLES OR 47.2 KM ALONG TWO LINES.
The Offshore New Harbor team has done an amazing job of working flat out since we arrived in Antarctica, first to build the seismic sled at McMurdo, fix all of the equipment break downs that we had while in the field and then setting records for collecting seismic data over the sea ice using this method.
Records set by the Offshore New Harbor Expedition Team
Seismic data collected on sea ice
Most seismic data collected in a season 47.2 km
Longest dip line 15.2 km
Longest non-dip line 32.0 km
Longest distance of seismic data collected in one day on first year ice
4.0 km (done on 11/4)
Most seismic data in one day on multi year ice (6 meters plus)
3.4 km (done on 11/20), previous record: 3.2 km on 11/13
Here is the daily record of seismic data collected over the past three weeks.
NOTE:
On line one, the first 18 km were on first year ice and 14 km on multi year ice.
On line two, the first 2.8 km were on first year ice and the rest was multi-year ice.
Multi year ice was between 6.2 and 6.6 meters thick on Line one and between 6.5 and 7.2 meters on line two.
We tried to finish off the last 7 holes on November 22, but the drilling equipment broke before we could finish one hole. Clearly, the spirits of Antarctic science thought we had done enough. So we started the break down of equipment and of the camp and that night celebrated well into the early morning. That evening, the clouds were producing spectacular vistas for us to view lighting up the camp with gentle hues and shadows that reminded us how special this place is.
