The second of two clear days allowed the continuation of flooding for ice thickening at primary coring site D1, and also the arrival via helicopter of ten people to the lake. This influx included the drilling crew from DOSECC, operations support personnel, and Russian drillers and camp staff, and together with the addition of overland convoy drivers brought the population of Camp El'gygytgyn to 30 people at present. Strong winds and low visibility slowed work progress during the next three days, but despite the difficult conditions flooding continued at D1 yesterday. This morning dawned crystal clear and calm, with a temperature of -34°C: perfect conditions for flooding. The pumps delivered 1400 metric tons of water to the D1 ice surface over the course of four hours. We plan for additional flooding in the coming days and the arrival of the first of the DOSECC containers with the drilling platform and equipment.
