Abstract Previous studies that have considered the ocean circulation on Enceladus generally assumed salinity to be Earth-like. However, according observations and geochemical constraints, of Enceladus’s is likely lower, importantly, it probably low enough reverse sign thermal expansivity. We investigate stratification using a combination theoretical arguments simulations MITgcm. find if high, w...

Article history: Received 22 November 2013 Received in revised form 24 June 2014 Accepted 16 August 2014 Available online 28 August 2014 The ability of a hydrodynamic model to reproduce the results of a dye release experiment conducted in a wide shelf sea environment was investigated with the help of the Massachusetts Institute of Technology general circulation model (MITgcm). In the field expe...

Radiative-transfer (RT) is a key component for investigating atmospheres of planetary bodies. With the 3D nature exoplanet being important in giving rise to their observable properties, accurate and fast methods are required be developed meet future multi-dimensional temporal data sets. We develop an open source GPU RT code, gCMCRT, Monte Carlo forward model general use atmosphere problems. aim...

The climate is a non-equilibrium system undergoing the continuous action of forcing and dissipation. Under effect spatially inhomogeneous absorption solar energy, all components dynamically respond until an approximate steady state (or attractor) reached. However, multiple states can co-exist for given with same boundary conditions. Here, we apply Thermodynamic Diagnostic Tool (TheDiaTo) to inv...

Air-sea exchange of elemental mercury (Hg(0)) is a critical component of the global biogeochemical Hg cycle. To better understand variability in atmospheric and oceanic Hg(0), we collected high-resolution measurements across large gradients in seawater temperature, salinity, and productivity in the Pacific Ocean (20°N-15°S). We modeled surface ocean Hg inputs and losses using an ocean general c...

Internal solitary waves commonly observed in the coastal ocean are oftenmodeled by a nonlinear evolution equation of the Korteweg–de Vries type. Because these waves often propagate for long distances over several inertial periods, the effect of Earth’s background rotation is potentially significant. The relevant extension of the Kortweg–de Vries is then the Ostrovsky equation, which for interna...

We present the first comprehensive estimate of connectivity of passive pelagic particles released from coral reef habitat throughout the Hawaiian Archipelago. Potential connectivity is calculated using a Lagrangian particle transport model coupled offline with currents generated by an oceanographic circulation model, MITgcm. The connectivity matrices show a surprising degree of self-recruitment...
