[Exports_project_office] MBARI assets for EXPORTS cruise

[Andrea Fassbender]

Hi Dave, 

OK great. I have these dates in my calendar now. 

The ISUS can take the place of a bottle but ideally would be mounted vertically inside the bottle ring and above the CTD - see picture attached. 

Autonomous assets = Deep ISUS (rosette nitrate) + BGC SUMO (underway pH + nitrate)
pH sampling capability = spectrophotometer for pH analysis onboard during cruise

Cheers,

Andrea


Figure: Gray vertical housing is the ISUS battery pack. Blue vertical housing in the ISUS. Blue horizontal housing is the Deep See Durafet (DSD). The CTD is below the DSD. Multiple Niskin bottles were removed during sensor mounting, which is when this picture was taken. The bottles were then remounted outside of this internal structure.

Please keep dates open for May 21-23 for the last cruise planning meeting (someplace on the west coast).  Not sure if the NASA AMES folks will help you with your shipment (will get back to you on that).

I know ship berths are tight so I wanted to get in touch ASAP as we would require a berth for someone from my lab to manage all of these assets and run pH samples during the cruise.

>> Deep ISUS can be mounted on the rosette with its battery back and we can connect via cable to a computer to download the data after each cast - thus it is a standalone instrument with its own power. I would need to be in touch with a ship tech before the cruise to finalize a plan for mounting the sensor. The sensor depth limit is ~3000m.

>> The underway system can be mounted on a wall, so also doesn’t require much lab space. It does need to be near an underway line and sink. I can coordinate with the ship techs to see if there’s a reasonable place for this on the ship.
>> For pH, we would need some bench space for the instrument, water bath, and computer. The system will eject waste, so it needs to be somewhat near a sink. I can give you an estimate of the bench space requirements if that would help.
>> I can also provide 100 bottles for DIC/TA samples that my lab can run at MBARI in kind. The bottles are in 4 cases, which will require some space for storage.

>> Please let me know if you are still interested in the autonomous assets and pH sampling capabilities. As I did not budget for this in my NSF proposal, we would likely need support with shipping, and I can work up a cost estimate if necessary.
