The dock has a marked waterline, as we worry about the King Tides that happen twice a year.Here daily high water varies by as much as 9 ft over the days of a month and the tide from high to low water can be 25 ft so the increase in ocean level of just over ⅛ inches per year for the last few decades is certainly not something we might notice on a dock!
That is what NASA measure from space.
I am an engineer and believe the science.
Nothing is as depressing as the deliberate spread of ignorance in recent years
Under normal conditions, the high tides vary less than 2 feet during a month. When it is time for the King tides, it can be slightly more than 3 feet.
I have lived directly on land that is directly on the water for 64 years, using the tides to judge where I can go & when. It's not like the dock is not part of my yard & I do not observe it daily.
Because it is a part of my life every time I sit down to a meal, I am looking at it before I even go outside. What happens there affects life daily.
Unless the pilings & the land (as the dock is still even) have all been pushed up together by the bedrock, there is no average change here.
I do civil engineering work. Plumbing industrial plants for chemical processes (precise flows & mixes).
Also, I do know a bit about rise, fall, slope, fluid flow, hydraulics & perhaps another thing or 2.
In addition I have 40+ years experience with Heavy Automotive vehicles involved in delivering the chemicals.
And design better working parts than the factory did for some automatic transmissions.
And build race cars. (Now at a hobby level).
& off road trucks that have 18"s of articulation in the suspension.
What happens were you are may not be what is happening where I am.
Yes, ignorance abounds & it is stunning sometimes where it comes from.
