Thanks Heidi, got it. I see 13 casts, does that sound about right?
Thanks, Norm

Heidi and I have bottle files and other meta files from Sarmiento that we returned with, but no plans (no person) identified to take this further than what we walked off the ship with, which were processed to the point of binned data, etc.

Sasha also asked for exact bottle trip depths to provide to the GSFC HPLC lab, which I imagine everyone will want soon as their return samples are analyzed.

I also did SeaBASS formatting and compiled bottle files in Inia’s format (here attached). New this time, in case it helps, are the same bottle files but with standard deviations for each parameter measured. (…BottleFileSD…). Might be helpful. This time I also have extracted all the analog voltage data at the outset so that should help with the recalibrations we need to do.

Physical data are very noisy at the surface, even in the binned data, so we will probably have to do some more aggressive filtering. Optical data also don’t really look good, and will need a deep dive, similar to what we did last time, to bring things into line and do some meaningful QC. I would not consider any of the data ready for publication, but we can at least start looking at it more thoroughly. We could probably use a meeting to talk about how we’ll divide up these tasks at some point.

There are useful SeaBird .cnv files in the UnfilteredData, UnbinnedData, Bin1mData subdirectories (etc), and SeaBASS files for binned and unbinned data in the SeaBASS subdirectories. There are .mat compilations of the binned SeaBASS data in the SeaBASS subdir (but the SeaBASS files do not include, the secondary T&S (& O on the JC) sensors, but those data are in the .cnv files and in the attached bottle files.
