ocean — and other
observations by the Galileo spacecraft, which
made a handful of flybys in the 1990s.
Researchers are applying
observations made by Charles Darwin's grandson to find that small organisms carry water with them as they go — which means they might play a big role in mixing vast tracts of
ocean water

make detailed
observations of the geologically active region for the first time, including more advanced monitoring of activity at the
ocean bottom.

«Crucially, our study also suggests that tidal heating could
make deeply buried
oceans more accessible to future
observations by moving them closer to the surface,» said Joe Renaud of George Mason University, Fairfax, Virginia, a co-author on the paper.
Made from fibreglass, steel and concrete, the Bathurst Pineapple is complete with a gift shop, tourist information centre and
observation deck, boasting views that stretch as far as the Indian
Ocean.
Most of these data are in archives, but usingthem intelligently to depict the state of the
ocean and to assess time changes in it requiresknowing how the
observations were
made, what accuracies can be assigned to them, and generally how to approach them.
The empirical
observations made in atmosphere,
oceans, ice sheets and on biosphere have been important in this process.
That leads to the IPCC conclusion that it is «very likely» that anthropogenic factors have «
made a substantial contribution to upper
ocean warming» using a method independent of
observation estimates of the value of individual fluxes.
«Previous
observations have pointed to large methane plumes being released from the seabed in the relatively shallow sea off the northern coast of Siberia, but the latest findings were
made far away from land in the deep, open
ocean where the surface is usually capped by ice.»
The point is that this
observation is not very relevant if the outcome comes from a combination of relevant and persistently warming data from areas where the temperature is strongly correlated with increase in the heat content of
oceans, atmosphere and continental topmost layers, and almost totally irrelevant data from areas and seasons where and when exceptionally great natural variability of surface temperatures
makes these temperatures essentially irrelevant for the determination of longterm trends.
The
observations of the
oceans are relatively new and they're relatively shallow still, so I think, again, the time's right to really
make progress there.
Three scientific panels, reporting to the Steering Committee, were established to define the
observations needed in each of the main global domains (atmosphere,
oceans and land), to prepare specific programme elements and to
make recommendations for implementation:
I would assume that all that happens is that the transport of heat is changed in the model: if surface air temps in the model are too high compared to
observations, more heat is
made to go down into the
ocean, and vice versa.

Since that day at Pelican Cays, I have been fortunate to travel to many sites around the globe, ranging from the waters of the southern Pacific
Ocean to the crashing surf along the Pacific coast of North America, and what I see matches the
observations made by what now is an army of scientists: The Earth's flora and fauna are changing — shifting their geographic locations, altering when they reproduce or dying wholesale — as a result of human - induced global warming.
Scientists from the U.S. National Aeronautics and Space Administration (NASA) and DOE
made satellite
observations, which included sea surface height changes alongside data of
ocean temperatures accumulated from 1970 to 2004.
, so of course the adjustment needed was to
make the less stepped on
ocean observations (2/3 of earth) warmer rather than the land «data» (1/3) cooler.
Several estimates of the trend in
ocean heat content have been
made using the ARGO network of
ocean floats, satellite
observations of
ocean altimetry (Levitus et al., 2000, 2001; Willis et al., 2003), and climate models (Barnett et al., 2001; Crowley et al., 2003).
But well - characterized
observations of carbonate chemistry trends weren't
made at those sites, so it isn't possible to draw a direct line of causality between the acidification of the
ocean and a decline in coral skeleton building.
So, to understand the
ocean for example you can
make observations and collect data, but the only way you can do an «experiment» is «virtually» in a model.
