GRANADA, SPAIN — The expedition also has what we reckon must be one of the most well-travelled Picarro analyzer’s.  Dr. Antonio Delgado and his team from CSIC, Granada, received their isotopic CO₂ analyzer nearly two years ago.  In this time it’s been measuring up in the snowy Sierra Nevada, as well as well as on the Spanish plain.

The expedition also has what we reckon must be one of the most well-travelled Picarro analyzer’s.  Dr. Antonio Delgado and his team from CSIC, Granada, received their isotopic CO₂ analyzer nearly two years ago.  In this time it’s been measuring up in the snowy Sierra Nevada, as well as well as on the Spanish plain. The instrument is now installed on   Malaspina’s Hespérides expedition vessel,  working it’s way around the world (last we heard .. it was approaching the balmy waters of Southern Mexico).  

Antonio and his team are measuring the concentration and isotopic signal of CO₂ in surface sea water.  The water is pumped into an equilibration chamber and circulated first to an IR detector which measures the concentration of CO₂ (this detector was installed previously before we had the Picarro analyzer in the set up), and then to the Picarro isotopic CO₂ analyzer before being re-circulated back to the equilibration chamber. We wish Antonio and his team the very best for the rest of the expedition. This is important work and an ambitious project. The data that should come out of this trip could be extremely valuable. And if anyone out there has an analyzer that has clocked more air/sea travel miles, I'd like to hear about it.
