19th century chart of ocean currents
Chart of ocean currents. The direction of the currents is marked by arrows.There are 17 major surface ocean currents. They circulate water around the world affecting the movement of energy and moisture between the oceans and the atmosphere thus affecting the worlds weather. For example the Gulf Stream which originates in the Gulf of Mexico is a warm current making Western Europe warmer than other areas at the same latitiude. The Humboldt current is a cold low-salinity current flowing north-westwards from the southern tip of Chile to northern Peru. It has a cooling influence on Chile, Peru and Ecuador and is a major cause of the desert conditions in northern Chile and is the most productive marine ecosystem in the world providing about a fifth of the worlds fish supply. Changes in temperature of the Earths surface affect ocean currents and their impact

EDITORS COMMENTS
This 19th-century chart of ocean currents showcases the intricate network of water circulation that shapes our planet's climate and ecosystems. The chart, adorned with arrows indicating the direction of each current, reveals the presence of 17 major surface ocean currents. These powerful streams play a crucial role in circulating water around the globe, influencing the movement of energy and moisture between oceans and atmosphere, ultimately shaping weather patterns worldwide. One prominent example depicted on this print is the Gulf Stream, originating from the warm waters of the Gulf of Mexico. This current carries its tropical warmth to Western Europe, making it significantly milder than other regions at similar latitudes. Another notable current showcased here is the Humboldt Current, flowing cold and low-salinity waters northwestwards from Chile to Peru. Its cooling influence profoundly impacts these coastal countries while also contributing to desert conditions in northern Chile. Remarkably, this very same current supports one-fifth of global fish supplies by fostering an incredibly productive marine ecosystem. The interplay between Earth's surface temperature changes and these dynamic ocean currents cannot be understated as they continuously shape our world's climatic effects. As we contemplate this historical artifact capturing nature's complexity, it serves as a reminder that even small alterations in sea levels or temperatures can have profound environmental impacts on both land and sea alike – highlighting why understanding these intricate systems remains vital for addressing pressing issues such as climate change today.
