What if everyone went for a dip in Lake Michigan?

Posted February 11th, 2013 in Water Resource Economics

Today’s blog post features a fun bit of physics from Wired.com’s science blog.

Writer Rhett Allain, professor at Southeastern Louisiana University, received an interesting question over Twitter – “What would happen if everyone on the planet jumped in the water?”


 He writes:

“Let’s give a slightly refined version of the question.

‘If everyone on Earth went for a swim at the same time in Lake Michigan, how high would the water level rise?’

I have two primary assumptions to start with. First, I will assume that during this time the volume of water in Lake Michigan will be constant. So if the people make the water level rise, the water level will indeed rise instead of pushing water into the other Great Lakes. Second, I will assume that all of the humans in the lake are floating. If they aren’t ‘swimming’ or touching the bottom, then it will be easier to calculate the rise in the water level.”

Deadline extended! The IISG program, in cooperation with the @nationalparkservice at @indianadunesnps and @UrbanRivers in Chicago, is offering two internship opportunities to support conservation policy efforts. Sea Grant’s national Community Engaged Internship (CEI) program aims to broaden participation in coastal, ocean, Great Lakes, and marine sciences providing training and mentorship to the next generation of scientists, decision-makers, and citizens.

The program will do so by recruiting, retaining and engaging students in place-based research, extension, education, and/or communication that respects and integrates local ways of knowing.

Applications due April 21.
