A Semiautomated Approach for Quality Controlling Large Historical Ocean Temperature Archives
Publisher: American Meteorological Society
Abstract: This paper describes a method consisting of both automated statistical screening and manual quality control through expert visual inspection, which produces a historical ocean temperature archive of high quality?that is, ...
Fifty-Year Trends in Global Ocean Salinities and Their Relationship to Broad-Scale Warming
Publisher: American Meteorological Society
Abstract: Using over 1.6 million profiles of salinity, potential temperature, and neutral density from historical archives and the international Argo Program, this study develops the three-dimensional field of multidecadal linear ...
A 20-Yr Average of the Indonesian Throughflow: Regional Currents and the Interbasin Exchange
Publisher: American Meteorological Society
Abstract: Twenty years of monthly or more frequent repeat expendable bathythermograph data are used to estimate the mean geostrophic velocity and transport relative to 750 m of the Indonesian Throughflow (ITF) and its partitioning ...
Nonlinear Effects of Tropical Instability Waves on the Equatorial Pacific Circulation
Publisher: American Meteorological Society
Abstract: In a numerical model of the equatorial Pacific Ocean, the ?20-day period tropical instability waves, excited in the eastern half of the domain, are found to damp the strong zonal mean currents. The waves generate large, ...
Transport of Freshwater by the Oceans
Publisher: American Meteorological Society
Abstract: The global distribution of freshwater transport in the ocean is presented, based on an integration point at Bering Strait, which connects the Pacific and Atlantic oceans via the Artic Ocean. Through Bering Strait, 0.8 ? ...
Deep Ocean Changes near the Western Boundary of the South Pacific Ocean
Publisher: American Meteorological Society
Abstract: epeated occupations of two hydrographic sections in the southwest Pacific basin from the 1990s to 2000s track property changes of Antarctic Bottom Water (AABW). The largest property changes?warming, freshening, increase ...
Pressure Sensor Drifts in Argo and Their Impacts
Publisher: American Meteorological Society
Abstract: n recent years, autonomous profiling floats have become the prime component of the in situ ocean observing system through the implementation of the Argo program. These data are now the dominant input to estimates of the ...
Recent Bottom Water Warming in the Pacific Ocean
Publisher: American Meteorological Society
Abstract: Decadal changes of abyssal temperature in the Pacific Ocean are analyzed using high-quality, full-depth hydrographic sections, each occupied at least twice between 1984 and 2006. The deep warming found over this time period ...
Decadal Characterization of Indo-Pacific Ocean Subsurface Temperature Modes in SODA Reanalysis
Publisher: American Meteorological Society
Abstract: tudies of decadal-to-multidecadal ocean subsurface temperature variability are fundamental to improving the understanding of low-frequency climate signals. The present study uses the Simple Ocean Data Assimilation (SODA) ...
Changing Expendable Bathythermograph Fall Rates and Their Impact on Estimates of Thermosteric Sea Level Rise
Publisher: American Meteorological Society
Abstract: A time-varying warm bias in the global XBT data archive is demonstrated to be largely due to changes in the fall rate of XBT probes likely associated with small manufacturing changes at the factory. Deep-reaching XBTs have ...
