The poem looks at the ocean through a series of images, each one showing a different side of it. First it is a "vast blue blanket rolling in the breeze," which makes the sea feel soft, calm and almost comforting. Then it becomes a "wet forest" waiting to "grant life," suggesting the ocean is full of living things and is a source of life itself. The third image turns darker: the sea at night is mysterious, and it gives away "little of its secrets." Each line ends on an ellipsis, which leaves the thought hanging, as if the speaker is gazing out and letting each picture drift by.
The final line shifts from description to something personal. The ocean is an "adventure calling my name," so the speaker feels drawn in, even invited. The mood moves from peaceful to mysterious and finally to excited curiosity. Overall the speaker seems to feel awe, and a little eagerness to go and find out what the ocean hides.
