For Sela, witnessing a mesoscale eddy?those swirling giants beneath the ocean's surface?is a lifelong dream. These powerful vortices, the unseen engines directing the kinetic energy that sustains the seas, captivate her as both an engineer and an explorer. She believes she can navigate the ocean's depths and reach one of these massive whirlpools. Perhaps even enter it. After all, what's the purpose of building a submersible if not to discover what no one has ever seen before?
Yet, Sela faces her own challenges: a vulnerability to claustrophobia and the growing risk of losing contact with her team as she ventures deeper. The further down she goes, the louder a strange series of clicks becomes, while her onboard instruments ominously suggest she is not alone.
