Whatever Cal had expected of the Sargasso Sea, this wasn't it. The ocean spread wide and blue under a cloudless sky, only the slightest of swell disturbing the water. She swayed instinctively as she sketched.
"What are you sketching?" Dr. Franklyn came up behind her. "There is nothing to see." His white eyebrows lifted.
"That's what I'm sketching." Cal didn't turn to look at him.
"What?"
"Nothing." She held the sketchbook so he could see, then put the book away. "I'm supposed to record what we see and do." Cal put her hand up to shade her eyes and peered out over the water.
"At this point, the Sargasso Sea is mostly empty water with a few clumps of seaweed. As we get closer to the gyre, the clumps will get thicker and closer together. In some places, it may pose a hazard to the prop, but we'll see."
"The gyre?" Cal looked at him.
"Where the currents of the ocean circle and pull anything in the area together."
"Sounds dangerous."
