I was playing 1.8, trying to find a good seed for my husband and I to play and I came across a Deep Ocean...ugh! Thanks, MC! I swam east for a bit and then saw something in the water that wasn't...natural. So I swam south and found a temple! But a stupid Guardian killed me.
So I decided to X that one.
Next one I did "default" biomes (on mistake) and it came up with this seed that lands you in the water next to an island with some birch, oaks, a handful of sheep, and a few chickens. RIGHT next to the island (but not close enough to get killed by Guardians) was ANOTHER underwater temple.
Um. YEA. This is a keeper.
You have enough food to get you going and a nice little island to punch trees and get some weapons, a house, and to mine far enough to get some ore. I haven't dug around much yet, still early...but if you allow night to come and kill some spiders, you could fish for food and have that awesome temple to explore.
