Sea freights impact on Sea levels

The world's shipping fleet is a vital part of the global economy. It transports goods and materials to all corners of the world, and it plays a key role in the global supply chain. The growth of the world's shipping fleet is a sign of the increasing globalisation of the economy, and it is a challenge that must be met with careful planning and management.

The total tonnage of all the world's shipping, including civilian and military, is estimated to be around 2.2 billion deadweight tons (dwt). The majority of the world's shipping fleet is made up of civilian vessels, which account for around 95% of the total tonnage. Military vessels are the remaining 5%.

Shipping fleets are now thankfully back to being a growing transportation sector, and this growth is expected to continue. This growth is being driven by several factors, including the increasing demand for global trade, the need to transport goods and materials to remote locations, and the increasing use of larger container ships.

This growth has many implications including adding to the total amount of water displaced by shipping which is currently 2.2 billion deadweight tons or 220 cubic kilometres. This is equivalent to the volume of water in Lake Erie, a lake that you can be seen from Space. This means that the world's ships displace about 0.16% of the total volume of water in the sea. If you were to take all the water displaced by ships and pour it into a giant cube, the world's ships would displace a cube that is roughly 16 kilometers on each side.

The 0.16% displacement in height is based on the average depth of water that is displaced by a ship relative to the height of the water. For example, if a ship is 100 meters long and 10 meters wide, and the average depth of the water is 100 meters, then the ship will displace 1,600 cubic meters of water. This is equivalent to a height of 1.6 meters.

The percentage of water displaced seems small, but it's a significant amount of water, in some areas, as this will raise sea levels locally, and it has some other implications. Though it does not cause changes in the salinity of the water, as a volume increase due to displacement cannot increase salinity or impact marine life other than submerging coral atolls deeper temporarily. It can however increase the risk of flooding if enough ships are in one area, especially in coastal areas where ships tend to moor for offloading goods. Third, it can contribute to the erosion of shorelines due to the extra displacement. This also goes for any additional equipment added to the ocean, such as oil rigs, and wind turbines, but at this time shipping is the largest cause of water displacement other than natural phenomena.

The extra effect of ships moving displacing water and tidal currents is complex and depends on several factors, including the size and speed of the ships, the depth of the water, and the shape of the seabed. In general, large ships moving at high speeds have a greater impact on water displacement and tidal currents than small ships moving at low speeds. This is because large ships displace more water, and their wakes can cause significant turbulence.

The depth of the water also affects the impact of shipping on water displacement and tidal currents. In shallow water, the wakes of ships can be more pronounced, and they can cause more turbulence. This can disrupt the flow of tidal currents. In areas with a lot of shoals and reefs, the wakes of ships can be more pronounced, and they can cause more turbulence. For example, a large container ship can displace up to 100,000 tons of water. This is equivalent to the volume of water in a large swimming pool.

You have to think if we add batteries to ships to power them and increase the number of our ships in the next 50 years if it hits a .5% increase in the volume of water what will that cause as the ships will weigh heavier. We should include the sea shipping and military factor when calculating possible sea level rises. Salinity decreases due to sea level rises caused by adding fresh water. If that happens, we only have the ice melting to blame. If sea levels rise and the salinity does not change there are other factors in play that need to be addressed.?

Hope you found this post interesting and please buy my batteries that we will ship by boat :)
