Sea currents: Key to the survival of our oceans discovered!

sea currents play a crucial role in the spread of marine species and influence profoundly ecological systems and climate conditions on earth. According to a report by Kleine Zeitung Sea creatures often distribute accordingly global currents. These dynamic water movements enable molluses such as mussels, snails and ink fishing, spread over large distances, which is illustrated by historical events such as the closure of the lands of Panama 2.8 million years ago. Scientists Thomas Neubauer and Mathias Harzhauser analyzed more than three million distribution data of Mariner molluscoisy and come to the conclusion that the difference between the molluster faunes in the tropical Eastern Pacific and West Atlantic is significant.

The analysis outlines the effects of temperature and sea currents on life in flat sea waters. This is particularly relevant in the context of climate change, which is widely seen as a serious threat to marine species and ecosystems. The rapid warming of the climate changes the temperatures of the surface of the sea and thus also has far -reaching consequences for global sea currents.

meaning of sea currents

But the effects of sea currents are not limited to the wildlife. They are a central factor for the earth's climate, as is highlighted in an article on Copernicus Marine . Sea currents transport heat, nutrients and organisms over the oceans and thus also significantly influence the weather and shipping. By optimizing shipping routes along the surface currents, transport times can be minimized, fuel saved and risks are reduced by extreme weather.

surface currents range up to a maximum depth of about 100 meters and are driven by surface winds and tidal flow. In contrast, deep sea trends arise from differences in the waterproof, which are regulated by temperature and salinity. These complex movements can be observed globally both for a short time and in the long term and influence the marine ecology.

consequences of climate change

The effects of climate change on the sea ecosystems are pressing and worrying. As in an article on Determined knowledge , sea ecosystems suffer from increasing temperatures, oceanic dusk and melting the polar caps. These changes not only have ecological, but also economic and social consequences. Increasing sea temperatures lead to changes in the species composition and a loss of biodiversity. Coral reefs that suffer from coral bleach are particularly at risk, which again results in the loss of valuable habitats for numerous marine species.

In addition, the increase in sea level threatens coastal ecosystems such as mangrove forests and wetlands and leads to a drastic loss of habitats. Experts emphasize the urgent need for measures to reduce greenhouse gas emissions and the development of effective adaptation strategies. International cooperation and scientific research are considered necessary in order to better understand the effects of climate change on marine systems and to take appropriate protective measures.
