The Tide Between Us: An Irish-Caribbean Story of Slavery & Emancipation (The O'Neill Trilogy Book 1)

In 1841 a Jesuit priest recorded the arrival of a ship from Limerick, “They landed in Kingston wearing their best clothes and temperance medals. Seleucus was the first to link tides to the lunar attraction, and that the height of the tides depends on the moon's position relative to the Sun. In the first case, the energy amount is entirely determined by the timing and tidal current magnitude.

While negligible for most human activities, terrestrial tides' semi-diurnal amplitude can reach about 55 centimetres (22in) at the Equator—15 centimetres (5. S.), low tide occurs roughly at moonrise and high tide with a high Moon, corresponding to the simple gravity model of two tidal bulges; at most places however, the Moon and tides have a phase shift.Some were convicts, many indentured servants and very few of the Irish deportees had committed any great crimes. As with tide height predictions, tide flow predictions based only on astronomical factors do not incorporate weather conditions, which can completely change the outcome. They reach their maximums in rings 45° from the points directly beneath and away from the sun or moon. Pytheas travelled to the British Isles about 325 BC and seems to be the first to have related spring tides to the phase of the moon.

The time taken for the wave to travel around the ocean also means that there is a delay between the phases of the Moon and their effect on the tide. They establish a new equilibrium ocean surface which bulges toward the moon on one side and away from the moon on the other side. History of tidal observation Brouscon's Almanach of 1546: Compass bearings of high waters in the Bay of Biscay (left) and the coast from Brittany to Dover (right). There are some extreme cases; the Bay of Fundy, on the east coast of Canada, is often stated to have the world's highest tides because of its shape, bathymetry, and its distance from the continental shelf edge. The graph of Cook Strait's tides shows separately the high water and low water height and time, through November 2007; these are not measured values but instead are calculated from tidal parameters derived from years-old measurements.

Atmospheric tides are both gravitational and thermal in origin and are the dominant dynamics from about 80 to 120 kilometres (50 to 75mi), above which the molecular density becomes too low to support fluid behavior. Tides vary on timescales ranging from hours to years due to a number of factors, which determine the lunitidal interval.
