Hi guys,Not sure if anyone knows the answer or wondering the same themselves but how come tide here is always above 0m. I understand that a 2.3m high is 2m above a 0.3m low, but what is the 0.3m above? Is it the tide level at the equator, or is it something completely different?Also why can a tide here have say a 1m variation, but up Broome way there is a 10m variation (rough figures)? Last but not least what causes a dodge tide. My guess is the position of the moon and its pull but why can it stay near one level for say 12 hours when a tide normally changed roughly every 6?Thanks heaps in adv
