Sea Without a Shore: Life in the Sargasso

Five major currents in the Atlantic Ocean "swirl billions of gallons of water clockwise around and around," creating an immense body of water, called the Sargasso Sea after the floating sargassum forests within it. Though it's known as seaweed, Rosenstock (Mornings with Monet) explains in clear, punchy prose that sargassum is an algae that reproduces when small pieces break off and then photosynthesize, growing stipes and blades as "gas-filled globes keep the weed on the surface." In carefully drafted naturalistic watercolors, Roy (The Fire of Stars) paints the sargassum floating in the blue sea as sunlight streams down, then focuses on the tiny creatures that settle upon it, in turn supporting more sophisticated life-forms: "Pinching Crabs,/ Skittering Shrimp." These beings tidy the weed, which keeps "floating,/ around and around," a phrase whose repetition reinforces the sea's sense of movement. As the title indicates, seas don't need seashores to be distinct, nor do thriving ecosystems require land. Around a series of ever larger creatures depicted--fish, turtles, and whales, all sustained by sargassum-supported life--are images of people of various skin tones interacting with the algae.
