FIGURE 14 | Total number of profiles with temperature and salinity that extend to at least 1,000 dbar for every 1° square of latitude and longitude. (A) World Ocean
Database 2013 with updates from January 2018. These represent nrofiles collected by research or other vessels over the past 150 vears. (B) Profiles collected by
Arao up to January 2019.
While the current accuracies in Argo data are sufficient
to meet Argos global change objectives, the program aims
to improve on these. Ongoing sensor development by
manufacturers and improvements in delayed-mode quality
control processes will contribute to this goal. Looking forward,
Argo is expanding to provide more coverage in marginal
rontiers in Marine Science | www.frontiersin.or
seas, more full-depth CTD profiles, and more biogeochemical
measurements to study issues such as the ocean carbon cycle,
deoxygenation, and ocean acidification. The future is evolving
for this global ocean observing system, and the expanded vision
will require similar international collaboration as over the past
20 years.
