Gulf Stream and the carbon cycle (Japanese subtitles)

We are all aware of how the Gulf Stream is important in the transfer of heat in the climate system. In this video, we explore our view that the Gulf Stream plays a similarly important role in the ocean carbon cycle. The Gulf Stream transports nutrients and waters that can uptake carbon at depth, when these waters reach the surface at high latitudes there is an uptake of carbon dioxide from the atmosphere. Thus, in our view, the Gulf Stream helps determine the downstream carbon sink for the North Atlantic.
We are conducting a research project called C-Streams to understand this process, supported by the UK Natural Environment Research Council and the US National Science Foundation.

Density-driven circulation in an estuary

Просмотров 5 тыс.4 года назад

This is a simple laboratory demonstration to show what happens to low-salinity (low density) estuary water when it enters the high-salinity (higher density) ocean. The low density estuarine water will float above the higher density seawater. This generates an average flow out of the estuary at the surface and an inflow of salty water near the bed, called “estuarine” or “density-driven” circulat...

The Atlantic Meridional Overturning

This laboratory demonstration shows a key process that maintains a large-scale but slow circulation in the Atlantic Ocean that is an important part of how Earth’s climate works. Near the equator warming of the surface ocean by the strong sunlight produces a layer of warm, low-density surface water that starts to spread northwards (in the real ocean this northward movement is helped by the avera...

This is a simple laboratory demonstration showing what happens to the flow of water that has an intermediate density, between a lower density upper layer of water and a higher density deeper layer of water. The intermediate density water will flow at the depth where it is stable - it has a lower density that the water immediately below it but a higher density than the water above it. An example...

This animation forms part of the series “Carbon and Climate”, which is an ideal introduction to how carbon dioxide and the climate interact, and is intended for school children, teachers and interested members of the general public. Scientists predict the rise in global temperatures from carbon dioxide emissions by using computer models. The video considers how different models give slightly di...

This animation forms part of the series “Carbon and Climate”, which is an ideal introduction to how carbon dioxide and the climate interact, and is intended for school children, teachers and interested members of the general public. It considers how much carbon dioxide has been added to the atmosphere during your lifetime, how the land and ocean absorb CO2, and why a smaller and smaller fractio...

This video looks at how the very small can have a huge impact on one of the most important things on Earth... the climate. Photosynthesis removes carbon dioxide, one of the gases responsible for warming of the atmosphere. But where does photosynthesis take place?
