It's somewhere near Mossdeep city.Go to route 127 and dive to the diving area.Go down to a diving area until u see another diving area to your left and dive there but you don't have to.Go down until u reach the end of the path and dive up and u will be in other side of the diving area and go to route 128.Actaully you do have to dive in the diving area in route 127 when u see the another dive spot to your left.Go down then right then down and then go to the cave u see.Dive up and congratulations,your in sea floor cavern. I'll also kindly help u get through the cavern. Go left and up and smash the rock and push the boulder down wards and go right and push the boulder and go up and beat up the aqua grunt and go to the cave. Smash the left rock and push the boulder up and smash the right rock and push the boulder right wards. Surf right then down then right then up then left and go back to the sea then up then right then up then left then down right to get back to sea and to the cave.And karate the aqua Grunts and to the cave.Push the middle boulder up wards and left boulder left wards and right one right wards and up and push 2nd middle boulder right wards and 3rd middle boulder up wards and left boulder Left wards and the up boulder up wards and down and right boulder right and up boulder up wards and up then middle boulder left wards and to the cave.Get TM earthquake which u see and teach it to your Sceptile or Swampert.Go down and go to kyogre.Then Archie will show up.Beat him up until his nose is bleeding.Then team Magma and Maxie will help u get to sootopolise.U can do this after you finished exploring magma and aqua hideout. After you've beaten the Elite 4, go back to the cavern and u catch Kyogre. U can do this by talking to the weather man weather building which is next to Fortree city and if he says rainfall,you can get to Kyogre but go to the route he said but be quick and save the game.Normally Kyogre is quicker to get to then Groudon.There are 2 reasons why to catch Kyogre:1, because he's quicker and 2, he can use water moves which can hurt Groudon a lot.
you have to have diamond, or pearl, or platinum-emerald is hoen sea temple Pokemon are sinnoh
go to the sea lair
Old sea chart

Only by a Nintendo event.
there is no saffron city in Pokemon emerald, and there is no "Pokemon bluesea" but you can catch both Groudon and Kyrouge in emerald... blue sea is a fake created by some guy who needed some money.
if u give it to seadra (the sea hourse pokemon) and trade it it will evolve
no unless u trade from emerald a Pokemon holding a deep sea scale
You can't without using cheatcodes. The Old Sea Chart is only obtainable and useable in Pokemon Emerald.
