April Meeting

Speaker: Roy Bishop
Topic: Lunar Waves — Tidal Bores
Avonport, 475 Bluff Road
Saturday, April 14, 7 p.m.

Summary:
Our Moon is the main cause of ocean tides. In addition to the varying level of the sea, at a few places on Earth, including the Bay of Fundy, conditions are such that a rising tide will announce its arrival, not by slowly creeping higher, but by suddenly rolling into view as a tumbling, noisy, hydraulic jump, commonly called a tidal bore. An understanding of water waves, gravity, and lunar cycles not only enhances our appreciation of visits to the sea coast, it makes tidal bores far from boring, and can even add interest to washing dishes in the kitchen sink.
