Among the NSF - funded programs facing potentially severe reductions are clean energy research and development and the Ocean Observatories Initiative, an array of marine and seismic sensors scattered across the Atlantic and Pacific oceans that is expected to provide some of the most
detailed ocean measurements to date (SN: 10/19/13, p. 22).

These monitors provided
detailed local
measurements but due to their limited range,
oceans and low - population areas were poorly represented.
Very recent, wide ranging review of temperature
measurements in the
oceans with a
detailed discussion of the accuracy of the data, planetary energy balance and the effect of the warming on sea levels.
Yet
measurements from more than 3600 automated buoys throughout the
ocean that dive down a mile and a quarter and take
detailed temperature and salinity profiles every ten days show that the deeper strata are warming faster than the near - surface strata.
To conduct the research, a team of scientists led by John Fasullo of the US National Center for Atmospheric Research in Boulder, Colorado, combined data from three sources: NASA's GRACE satellites, which make
detailed measurements of Earth's gravitational field, enabling scientists to monitor changes in the mass of continents; the Argo global array of 3,000 free - drifting floats, which measure the temperature and salinity of the upper layers of the
oceans; and satellite - based altimeters that are continuously calibrated against a network of tide gauges.
Facilitated by the invention of an elegant and precise wet - chemical method by Winkler (1888), which has remained essentially unchanged until today, reliable and comparable oxygen
measurements have been made during innumerable research cruises to all parts of world
ocean such that a
detailed picture of the distribution of oxygen has emerged long since.
Before we look at the causes, here are a series of
detailed measurements from Near - surface
ocean temperature by Ward (2006):
For
detail on the
ocean measurement system and its limits, then I guess start with Von Schuckmann and La Treon.
Like all other science, climatology is data - driven, and the data is constantly flooding in:
measurements of change in bird - migration patterns;
details of
ocean temperatures and wind pro?les;
measurements of the calcification of coral, the ripening of grapes, the retreat of glaciers, and so on.
Since 2003, the
detailed gravity
measurements from Gravity Recovery and Climate Experiment (GRACE) of the change in glacial land ice and water show an increase in mass of the
ocean.
