The sensitivity of the upper ocean thermal balance of an ocean-atmosphere coupled GCM to lateral ocean physics is assessed. Three 40-year simulations are performed using horizontal mixing, isopycnal mixing, and isopycnal mixing plus eddy induced advection.

AbstractDespite the Pacific being the location of the earliest seawater Cd studies, the processes which control Cd distributions in this region remain incompletely understood, largely due to the sparsity of data. Here, we present dissolved Cd and δ114Cd data from the US GEOTRACES GP15 meridional transect along 152°W from the Alaskan margin to the ...

Effects of physical changes in the ocean on the atmospheric pCO2: glacial-interglacial cycles
Climate Dynamics, 2009Based on LGM experiments with an atmosphere–ocean general circulation model, we systematically investigated the effects of physical changes in the ocean and induced biological effects as well on the low atmospheric CO2 concentration (pCO2) at the last glacial maximum (LGM).

Impact of Ocean Physical Conditions on Ocean Carbon Pumps and Atmospheric CO2
During glacial periods, atmospheric CO2 concentrations are known to have been about 90 ppmv lower than during interglacial. However, climate models have not been able to fully reproduce this decrease, partly due to large uncertainties in changes in ocean physical fields. In this study, we evaluate the impact of uncertainties in ocean physical fields onMiyano Nishida +2 more

Methods for Observation Data Assimilation in Problems of Physics of Atmosphere and Ocean
Izvestiya, Atmospheric and Oceanic Physics, 2019This paper presents a review and analysis of approaches to data assimilation in problems of geophysical hydrodynamics, from the simplest sequential assimilation schemes to modern variational methods. Special attention is paid to the study of the problem of variational assimilation in a weak formulation, in particular, to the construction of an ...

Abstract Sensitivity of climate drift to selected convection and cloudiness parameters is investigated with a coupled ocean–atmosphere general circulation model. The dependence of the coupled model climatology upon parameterizations of convective entrainment and stratocumulus cloud cover is studied.

Abstract The Great Oxidation Event (GOE) is one of the most significant changes in seawater and atmospheric chemistry in Earth history. This rise in oxygen occurred between ca. 2.4 and 2.3 Ga and set the stage for oxidative chemical weathering, wholesale changes in ocean chemistry, and the evolution of multicelluar life.
