Chesapeake Bay in the northern portion of the Bay, experiences a noticeable modulation to form its mixed tidal nature during spring vs. neap tides. Spring tides, when the sun-earth-moon system forms a line, cause the largest tidal amplitudes during lunar monthly tidal variations. In contrast, neap tides, when the sun-earth-moon system forms a right angle, are muted, and in a semi-diurnal tidal system (such as that seen at the CBBT site) this can be seen as a lowest intertidal range. Two interesting points that arise from comparing these two sites at opposite ends of the Bay are their tidal characteristics - semi-diurnal

It is based on the "ancient phrase" "The big sea does not care which way the little fishes swim", which Pratchett made up at some point before the story, and finally used in "Night Watch".
