Maybe add a caveat that the Gulf of Mexico counts as the ocean here.

What would the Gulf of Mexico otherwise be? A lake?

JetPunk standard is that marginal seas are considered part of the ocean.

For Maryland, this counts the Chesapeake Bay as the “ocean.” I don’t think many Marylanders would think about the Bay if you tell them you’re “Goin’ downee ocean, Hon!” Excluding the Chesapeake and Delaware Bays, far western Maryland is about 242 miles from the Atlantic Ocean at Cape Henlopen, Delaware.

It's connected to the ocean, any body of water that isn't a lake or a river is part of the wider global ocean.

Take the Mediterranean as an example, while it itself is a sea, it is part of the ocean.

For Maine now I'm curious at what point the St. Lawrence River becomes wide enough and salty enough after draining the entire Great Lakes basin to be considered ocean.

I know they have considerably high tides as the river broadens, and you can't see from one side to the other. Cool little quest detour coming up.

Good question. It has always been my impression that anything east of Quebec City (or Ile d'Orleans) is sea water.

I found out that at Rimouski salinity is about like the Gulf Of Maine, although not on the very surface due to runoff. And depth is over 300 meters whereas G.O.M. 100 meters is deep, with less than 200m being the maximum. I know New England commercial fishing boats used to go for the same species from home all the way well past Anticosti Island before Reagan started enforcing the Magnuson Act with his executive order to extend U.S. waters from 3 nautical miles to 12.

Here's a great explanation of the transition from river to estuary to gulf. So depending on whether or not you count an Estuary as part of the ocean, it would either start at Ile d'Orleans at Quebec City, or at Pointe-des-Monts where the channel deepens and widens into a gulf.

Another argument could be made for Tadoussac/Prince Shoal Light as the point where the channel becomes the ocean. At that point the estuary reaches average sea level and becomes fully saline. The tidal upwelling of deeper sea water there results in an abundance of sea life in the area.

Things like shortest maximum and maximal minimum always fry my brain... the 165 miles or less in the description helped ( well, not the miles part.. ) otherwise I would have sat here for minutes trying to assure myself what the concept of the quiz is haha.

Good quiz, though I'm a little confused about what you mean by maximum distance. Could you perhaps explain it to me?

For each state you find the point in the state that is furthest from the sea. That is the maximum distance. Then you find the states where that distance is the shortest.

Is it possible to js say "Most Coastal US States" or "Most Ocean-Proximate US States" or "US States Least Far From the Ocean" and say the methodology in the desc? Or would thatn't work
