Exploiting Tomorrow's Solar Eclipse To Help Understand Sea Levels

mdsolar writes "Tomorrow at dawn on the U.S. East Coast, a partial solar eclipse will rise. Solar eclipses have many uses. They can confirm the Theory of Relativity, allow study of the solar corona, and this week, help prepare for global warming induced sea level rise. The tides induced in the oceans when the Sun and Moon are aligned are particularly high (and low) and give a foretaste of the effects of sea level rise in the coming decades. Maryland's Department of Natural Resources is asking for photos of these King Tides to help with preparation for the effect of sea level rise. Way to get out front, Maryland."

  1. Yes, it is. by Okian+Warrior · · Score: 2, Informative

    To "get in front of a problem" is slang, meaning to take steps to mitigate a predicted problem before it happens.

    I've only heard it in use recently, so it's probably a recent addition. It's the "ounce of prevention" that is worth the "pound of cure".

      I'm American and I've definitely heard "get in front of a problem" but I've never heard it shortened to just "get out front" as it was in the story (nor removed from context as it was). I was confused as well. Perhaps the submitter was just being idiosyncratic.

    This is cute, but the difference in tidal forces between an eclipse and any other full moon is not very much-- the moon and sun are still pretty closely lined up. If it's within a few months of an eclipse, the difference is trivial. Or, for that matter, a lunar eclipse would also be as good.
    Next month's full moon will have (very slightly) higher tides-- the Earth is a month closer to perihelion.

      I don't think parent post is quite right.

      The spring tide of an eclipse day is probably not significantly higher than any other spring tide when all other things are equal. But the existence of perigee and perihelion means that other things may not be equal.

      This particular eclipse happens near perigee, as the Moon nears its closest approach to the Earth. This does make for a king tide, a high tide that is significantly higher than other spring tides. Also the Earth is coming up on perihelion in a few weeks, as parent post states, when it is at its closest approach to the Sun. That will also push the tide higher.

      Additionally, Maryland is positioned relative to the line of the eclipse such that the tidal bulge will be higher at Maryland's shores than at, say New York or Georgia, that are at roughly the same longitude.

  3. Eclipse as Propoganda by SuperKendall · · Score: 4, Informative

    Nothing like using an unusually high tide to scare people about global warming, even though ocean levels are now predicted to rise something like 4" over 100 years (NOT four feet as the government website sadly parrots) ... the variance of a good spring tide can be more than that.

    It's just really sad to see people conned in the name of science.
