  bringing out a large wrinkled roll of yellowish sea charts, spread them before him on his screwed-down table. Then seating himself before it, you would have seen him intently study the various lines and shadings which there met his eye; and with slow but steady pencil trace additional courses over spaces that before were blank

  reasoning

  The source entity 'sea charts' are described as maps Captain Ahab uses to 'plot courses and predict the movements of sperm whales'. Candidate 2, 'migratory charts of the sperm whale', is described as 'detailed maps that illustrate the predictable migration routes and patterns of sperm whales worldwide' with the purpose 'predict whale movements'. Both entities refer to maps used for tracking sperm whale movements. The source entity is a specific instance (artifact) of such charts, while Candidate 2 is the general concept or ongoing development of these charts, as evidenced by its relationship to the 'Official Circular (Maury, 1851)' which confirmed their validity and included portions of a chart in progress. The shared purpose and context strongly indicate they refer to the same type of real-world object/concept.
