Then, it gets into what influences ocean currents. For example, the wind, tides, water density, rotation, and even ocean floor topography influence currents in the oceans. Finally, the lesson contrasts the differences between surface and deep ocean currents. For example, surface currents control t...
Topographic map of the Nordic Seas and subpolar basins with schematic circulation of surface currents (solid curves) and deep currents (dashed curves) that form a portion of the Atlantic meridional overturning circulation. Colors of curves indicate approximate temperatures. Credit: R. Curry, Woods Ho...

The scale of turbidity currents ensures that the sediment-mass carried by these flows rivals that of any other process on Earth1,13, including rivers6or glaciers6, or settling from the surface ocean14(Table1). Turbidity currents are thus important for a wide variety of reasons. For example, ...

part of India is a ramp overthrust, with the steep part of the ramp dipping north beneath the Great Himalayas. Slip on this steep part allows the rapid uplift of the Great Himalayas, which in turn creates the high peaks and carries rock from deep in the crust to the Earth’s surface....
Based on these models, the report concludes that global surface temperature will continue to increase until at least the middle of this century under all emissions scenarios. Global warming targets of no more than1.5°C or 2°Cabove the pre-industrial average — the goal o...
stable hull over the water. As they progress outside of harbors, they claim to seamlessly transition to wave-tolerant underwater hydrofoils that enhance efficiency and minimize resistance. They then transform to flight at ultra-low altitudes of between 30 and 60 feet above the water’s surface....

surface open ocean. Four types of SDMs (generalized linear models, generalized additive models, artificial neural networks, and random forests24) are fitted to model the species’ current environmental habitat suitability patterns. For each SDM, we use four alternative pools of predictors. Assuming ...
