Number of profiles per year
"Raw" = profiles downloaded; "QC" = valid profiles; "prev" = previous download; "T/S/..." = non-empty profiles.
Interpolation onto standard depths can create empty profiles when there are few data points.

PFL notes: data from GDAC. "D" = delayded-mode, "A" = adjusted; "R" = real-time

PFL-BGC notes: data from GDAC. "D" = delayded-mode, "A" = adjusted; "R" = real-time

CTD notes: data from NCEI (WOD)

XBT notes: data from NCEI (WOD). "No flags" = data was originally submitted without QC flags; processed separately

MRB notes: data from NCEI (WOD).

MEOP notes: data from MEOP.

ITP notes: data from WHOI. L2 data processed separately from L3 ("QC") data

GLD notes: data from NCEI (WOD).
