The ocean floor sedimentological signature of Heinrich event 3 (H3) is markedly different from that of other Heinrich events that are known to have originated in Hudson Strait. It has therefore been suggested that the H3 contribution to iceberg flux

Analyses of glacial isostatic adjustment (GIA) and deglacial relative sea-level (RSL) change in the Russian Arctic deliver important insights into the Earth's viscosity structure and the deglaciation history of the Eurasian ice sheet complex. Here, w

We analyze the effects of nudging 100 kyr numerical simulations of the Laurentide and Fennoscandian ice-sheets towards the glacial isostatic adjustment-based (GIA-based) ICE-6G_C reconstruction of the most recent ice-age cycle. Starting with the ice

We describe a theoretical and numerical framework that has been developed to investigate the compatibility of the ICE-6G_C reconstruction of the glaciation histories of the Greenland and Antarctic ice sheets with the latest understanding of ice physi

Current models of the general circulation of the global oceans employ a spatial discretization of the relevant hydrodynamic fields on Cartesian rectilinear grids. For many applications, significant benefit would be expected to accrue from the versati

Clustering of organisms can be a consequence of social behaviour, or of the response of individuals to chemical and physical cues1. Environmental variability can also cause clustering: for example, marine turbulence transports plankton2,3,4,5,6,7,8 a

A one-dimensional dynamical model is derived which represents the evolution of mean zonal flow on a rapidly rotating spherical shell. This model is discussed and analyzed with reference to large-scale jet dynamics observed in geophysical and astrophy

We describe the implementation of numerical models of shallow water flow on the surface of the sphere, models which include the nondivergent barotropic limit as a special case. All of these models are specified in terms of a new grid-point-based meth

The pseudo-spectral methodology that is typically employed to simulate fluid flow in spherical geometry exhibits, among other limitations, a severe degradation of performance at high resolution. Finite element models based upon the application of mul
