Abstract

A significant impetus for recent ocean biogeochemical research has been
to better understand the ocean’s role as a sink for anthropogenic CO2. In
the 1990s the global carbon survey of theWorld Ocean Circulation Experiment
(WOCE) and the Joint Global Ocean Flux Study ( JGOFS) inspired
the development of several approaches for estimating anthropogenic carbon
inventories in the ocean interior. Most approaches agree that the total
global ocean inventory of Cant was around 120 Pg C in the mid-1990s. Today,
the ocean carbon uptake rate estimates suggest that the ocean is not
keeping pace with the CO2 emissions growth rate. Repeat occupations of
the WOCE/JGOFS survey lines consistently show increases in carbon inventories
over the last decade, but have not yet been synthesized enough to
verify a slowdown in the carbon storage rate. There are many uncertainties
in the future ocean carbon storage. Continued observations are necessary
to monitor changes and understand mechanisms controlling ocean carbon
uptake and storage in the future.
