Milton Carlo and Jorge Corredor re-installed the SAMI pCO2 today after Chris Langdon and Joanie Kleypas re-filled the SAMI with reagents and worked on the water sampler last week. The SAMI appears to be putting out good data again.

This site is for recording maintenance records of the La Parguera Marine Reserve NOAA ICON/CREWS station for data management purposes. Please update this blog whenever new operations are performed in the field, so that NOAA/AOML can coordinate data management efforts with the La Parguera ICON/CREWS station field efforts.

Update on BICs, SAMI
I cleaned the BICs on May 14. They were very fouled. On May 16 the SAMI was recovered, cleaned, and chemicals replaced. The battery was surprisingly still good,i.e. 13.1 volts so I did not replace it. The SAMI was reinstalled on the stick later in the day. Hopefully it is now reporting data.

Samples for Ocean Acidification Studies Taken
On 5/14/07 the BIC sensors were observed to be heavily fouled. I cleaned
both.
Water samples for TA, DIC and O2 were collected on 5/14. 5/15, 5/16, 5/17 and 5/18. These data indicate that the SAMI was reading high by 84 uatm before the change of chemicals on 5/16/07.
Jorge's SeaCat CTD was profiled at the stick on 5/15 and 5/18.
The AOML water sampler was deployed at the stck on 5/17 and 5/18 and collected twelve good samples. Unfortunately the SAMI was not operational that the time.
