Processes contributing to interannual steric sea level variability are studied over the period 1993 — 2004 using an observationally - constrained
ocean state estimate produced by the ECCO («Estimating the Circulation and Climate of the Ocean») consortium.
The study by Ponte (2012) is referenced for its use of an eddy - resolving
ocean state estimate to quantify the substantial variability in temperature and salinity expected in the deep ocean on time scales from months to years.

estimated to reside now in areas that could be hard hit as rising land and
ocean temperatures raise average sea levels around the globe.
Even if the initial atmosphere /
ocean state could be
estimated in an accurate quantitative manner, these will likely still hit the predictive wall owing to chaos.
Further, just as seasonal - to - interannual predictions start from an
estimate of the
state of the climate system, there is a growing realization that decadal and longer - term climate predictions could be initialized with
estimates of the current observed
state of the atmosphere,
oceans, cryosphere, and land surface.
«Despite recent advances in the
state of the global
ocean observing system,
estimating oceanic variability on basin - wide to global scales remains difficult.
State - of - the - art ecosystem models build on empirical observations of past climate changes and enable development of
estimates of how
ocean life may react in the future.
The prediction is made from an ice /

Published
estimates of anthropogenic CO2 now stored in the upper
ocean layers and affecting pH has been based on «the assumption that
ocean circulation and the biological pump have operated in a steady
state since preindustrial times» (Sabine 2010).
This approach allows us to
estimate the maximum predictability of the decadal anomalies assuming perfect knowledge of the initial
state of the
ocean and land.
This
states that the variability of fossil fuel emissions and
estimated variability in net
ocean uptake are too small to account for this signal and is therefore thought to be due to year - to - year fluctuations in the land - atmosphere fluxes.
