Oceans and seas ?

My depth is deep I hope you can swim.. I am totally tidal I turn on a whim.. I rock and roll and  I can get grim..sea sportsmen surf upon my skim.. I may look blue but I am not sad.. wild weather will worry me and make me so mad..so it is not my fault if I am bad.. people play in me I make them glad

I am a liquid so I am very wet.. boats sail on me amidst the scenic sunset.. carrying fishermen who catch fish in a net..but I can get rough lest they never forget..I will taste salty I will make your mouth dry.. though I shall saturate you I tell you no lie..I ebb and I flow from the moon in the sky..as it shines moonbeams upon me from way up high.. I splash from the raindrops as Mother nature will cry.. I am oceans and seas and I bid you goodbye
