I am studying mathematical modelling of ocean tides. In one of his articles, prof. Derek Goring talks about applications of his results. After mentioning assistance to the police in recovering bodies and other objects that have been thrown into the sea, tracking the propagation of oil spills, and calculations for marine farming of mussels, he goes on saying:
We also provide a tide-forecasting service for any location in the seas around New Zealand; our scientist
colleagues use this service to plan fieldwork and holidays.
Finally, we receive about one inquiry a week from prospective brides planning a wedding on a remote beach and trying to decide on which day and at what time to have it.
I love it! About once a week (fifty times a year) a prospective bride before her wedding day calls the Coastal Hydrodynamics Group of the National Institute of Water and Atmospheric Research with an inquiry on tide forecast. I wonder which other institutions they contact and what information they are looking for? The movement of tectonic plates? Seismic activity?
I would also recommend to get a precise forecast on fluctuations of atmospheric pressure, temperature, and sky cover because these factors affect mood.
