14 Aug 2007 Mooring day

Submitted by Byron Crump on August 18, 2007 - 10:51pm

Walt Waldorf and Craig Risien deployed a mooring near station NH-10. The water sampling group processed two samples (bottom and deep chl max) to determine volumes needed and to work out the kinks. The water chemistry group was the busiest - they did best with 3 people, but could also use filtering racks with larger funnels to hold more water. The ones they have now hold 200ml, but for most samples they can filter 2-4 liters through each filter. The DNA/RNA sampling group was pretty fast thanks to the two 3-head Geopumps we used. Each pump would pump a total of 30L through 6 sterivex filters. DNA/RNA sampling could be done by one person.
