A Global Evaluation of Ocean Bottom Pressure from GRACE, OMCT, and Steric-Corrected Altimetry
Publisher: American Meteorological Society
Abstract: Ocean bottom pressure (OBP) from the Gravity Recovery and Climate Experiment (GRACE) and the Ocean Model for Circulation and Tides (OMCT) are compared globally with OBP computed from altimetry corrected for steric variations ...
Upper-Ocean Contribution to Short-Term Regional Coastal Sea Level Variability along the United States
Publisher: American Meteorological Society
Abstract: he upper ocean thermal structure is largely influenced by natural internal variability, and it modulates global surface temperature as well as regional sea level anomalies over decadal time scales. The internal variability ...
Closing the Time-Varying Mass and Heat Budgets for Large Ocean Areas: The Tasman Box
Publisher: American Meteorological Society
Abstract: The role of oceanic advection in seasonal-to-interannual balances of mass and heat is studied using a 12-yr time series of quarterly eddy-resolving expendable bathythermograph (XBT) surveys around the perimeter of a region ...
The Observed North Atlantic Meridional Overturning Circulation: Its Meridional Coherence and Ocean Bottom Pressure
Publisher: American Meteorological Society
Abstract: nalyses of meridional transport time series from the Rapid Climate Change?Meridional Overturning Circulation (RAPID MOC) array at 26°N and from Argo float and altimetry data at 41°N reveal that, at semiannual and longer ...
In Situ Data Biases and Recent Ocean Heat Content Variability
Publisher: American Meteorological Society
Abstract: Two significant instrument biases have been identified in the in situ profile data used to estimate globally integrated upper-ocean heat content. A large cold bias was discovered in a small fraction of Argo floats along ...
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 ...
Quantifying Spread in Spatiotemporal Changes of Upper-Ocean Heat Content Estimates: An Internationally Coordinated Comparison
