Start from scratch

Now let's sum up the main points of the matter First of all the battleship Stainless Steel Welded Pipe broke when it sank and most of its contents fell out The second point The box was broken by a shell before it fell into the water and it could open itself at any time and drop out its contents The third point This is the ocean The current is very unstable This thing could fall anywhere "I see" said the Red Moon You mean the box fell into the water and opened itself and the things sold in it fell out "Yes!"! It must have fallen out or it would have been found with the box Different things are different because of their specific gravity and shape The ability to drift with the ocean currents is also different Specific gravity earth things are not easy to drift It will appear very close to the sinking site while the specific gravity sketch may be carried far away The Red Moon said "The box has been reinforced and the mass of the things inside is very large but judging from the size of the box it is not very large which means that this thing has a large proportion" The circular shape is not easily surrounded by ocean currents So it must be somewhere between here and where it happened "But I don't know where we fought" I said "Then follow the current upstream and that thing must have hit the bottom ahead of time upstream" "Can you feel the ocean current" I hastened to Adina 'Of Course It's not a sea creature if you can't feel it! "Now take us upstream" Instead of taking us away immediately Adina whispered "It sounds like I missed something in your conversation just now" "What are we missing" Red Moon looked curiously at Adina and waited for her answer "You didn't grow up in the sea" she replied "You may not know this but I know that unlike lakes and rivers the flow of the sea is not stable In some places the seasonal changes of ocean currents are very serious and even completely reversed "But it's only been a few days and the current won't change so much will it" "The problem is not just seasonal currents" said Adina Another problem is laminar flow The flow of water in the ocean is stratified The surface water flows in a different direction from the sea water below Some places drop 100 meters vertically and the sea water will change direction three or four times in a row The surface water is affected by the wind The middle water is affected by the salinity and temperature of the water The bottom water is affected by the topography of the sea floor and the gravitational pull of the moon This change will be so great that there is no way to determine the direction of the ocean current as you say We mermaids have experimented

From the same point on the sea throw a stone every minute a total of 100 pieces As a result they landed in 100 discrete positions the farthest of which were more than 700 kilometers apart It was a relatively stable day for ocean currents and if there were wind and waves or anything else Stainless Steel Square Pipe it would be over Red Moon and I were dumbfounded Is there such a strange situation in the sea Looks like we're keeping things simple! "How can we determine the exact location of that thing with your knowledge" I asked Adina "It is impossible to completely reproduce the current of the world" said Adina If you know the ratio of the drag coefficient of that thing in water to its specific gravity I can calculate the probable radius of its entry point But you don't even seem to know what that thing looks like which seems impossible There is another sad news I told you to stand up to it "What could be worse than that" Of course there is For example some giant sea creature swallowed it as food! From what you've just analyzed that thing is indigestible and if the creature pulls it out it could cover the whole earth in its place For example creatures like whales which like to migrate will run around the earth not knowing where the thing will be pulled out by it Maybe in the Pacific maybe in the Atlantic it's just a needle in a haystack If that thing doesn't come out of its stomach it's even worse
Looking for something that can run around at the bottom of the sea is more troublesome than looking for a needle in a haystack You can't catch all the sea creatures and open them to look for them can you Besides with the size of that thing the number of organisms that might swallow it is calculated in billions and it is impossible to be sure "Then you'll never find it" "The only way is to look for possible areas and hope that nothing eats it" Most sea creatures don't eat things that don't have life So the possibility of being eaten is not very high You don't have to worry too much I rekindled my hope "So how big is this possible area" I'll see how long it takes to finish the search "At least 5000 square kilometers!" "Forget it forget I said it" Such a large area has been searched and the national war should begin It's okay to 304 Stainless Steel Flat Steel find such a large area on land but it's impossible to find such a large area in the sea Red Moon also said "Unless we have 5000 people to search otherwise it is impossible to find" This range is too large I nodded "I think someone should be sent to watch them" As long as they don't find it we'd better not waste that manpower

The project is too huge! "Actually I have a plan" said Adina "What way" "Please ask Atlantis to help find it" Mermaids find things in the water as easily as you find things on land You can offer a reward of two magic spars to ensure that many mermaids come to help find them "That's a good idea but anyway now is not the time Let's go back first" "What about this side" "Destroy it first and affect their search speed" "Who" There was a sudden shout behind us Adina pulled the two of us forward to get out of the way of the flying harpoon Too bad they found out sxthsteel.com
