Green Blinking Hydrophone Rack Beside Chart Table

Clean laboratory light illuminates a hydrophone rack with a steady green LED blinking against a white chart table. The equipment sits in a room in Quezon City, where the humid air after rain leaves a faint sheen on the metal surfaces. A nautical chart lies flat on the table, its paper slightly curled at the edges from the moisture. Beside the rack, a blue pen rests on the chart near a plotted line. The green light reflects softly on the glass cover of the chart. Through a nearby window, blurred rain streaks the glass, hinting at the tropical afternoon outside. The green LED continues its rhythmic pulse against the sterile white background.
