Open AccessDepth-dependent warming of the Gulf of Eilat (Aqaba)
The Gulf of Eilat (Gulf of Aqaba) is a semi-enclosed basin situated at the northern end of the Red Sea, renowned for its exceptional marine ecosystem. To evaluate the response of the Gulf to climate variations...

Production of Neoproterozoic banded iron formations in a partially ice-covered ocean
The meridional extent of marine ice during the Neoproterozoic snowball Earth events is debated. Banded iron formations associated with the Sturtian glaciation are considered evidence for a completely ice-cover...

Open AccessUnraveling sub-seasonal precipitation variability in the Middle East via Indian Ocean sea surface temperature
This study examines sub-seasonal precipitation anomalies, challenging to predict yet vital for society and the environment. Focusing on October, we investigate correlations between the Indian Ocean Dipole Mode...

Heat Content from Gliders and Satellites: Eastern Mediterranean Case Study
Heat content measured directly by ocean gliders in the Eastern Mediterranean (EM) Sea is compared to heat content inferred from remotely sensed sea surface properties, assuming a simple reduced-gravity model. ...

Open AccessEffects of paleogeographic changes and CO2 variability on northern mid-latitudinal temperature gradients in the Cretaceous
The Cretaceous ‘greenhouse’ period (~145 to ~66 million years ago, Ma) in Earth’s history is relatively well documented by multiple paleoproxy records, which indicate that the meridional sea surface temperatur...

A Kinematic–Dynamic 3D Model for Density-Driven Ocean Flows: Construction, Global Well-Posedness, and Dynamics
Differential buoyancy sources at an ocean surface may induce a density-driven flow that joins faster flow components to create a multi-scale, 3D flow. Potential temperature and salinity are active tracers that...

The role of sea ice in the temperature-precipitation feedback of glacial cycles
The response of the hydrological cycle to climate variability and change is a critical open question, where model reliability is still unsatisfactory, yet upon which past climate history can shed some light. ...

Multiple sea-ice states and abrupt MOC transitions in a general circulation ocean model
Sea ice has been suggested, based on simple models, to play an important role in past glacial–interglacial oscillations via the so-called “sea-ice switch” mechanism. An important requirement for this mechanism...

Dynamics of a Snowball Earth ocean
Extensive glaciations, possibly even a globally ice-covered Snowball Earth, took place in the Neoproterozoic era, and here the possible ocean circulation at that time, under a kilometre of ice, is described.

Deducing an upper bound to the horizontal eddy diffusivity using a stochastic Lagrangian model
We present a method for estimating the upper bound of the horizontal eddy diffusivity using a non-stationary Lagrangian stochastic model. First, we identify a mixing barrier using a priori evidence (e.g., aeri...

Glacial-Interglacial CO 2 Variations
Earth’s climate undergoes variations on a wide range of time scales, from seasonal and interannual to glacial-interglacial and beyond. These variations are revealed in a variety of proxy records collected from...
