Tide challenge 2012

by

On 17 February, first year marine scientists were challenged to: “Design a method to measure the change in tidal height at the PC docks over 48 hours.”  They were required to have at least 20 data points within the 48 hour period.  Students came up with various methods, some of which are described below.

Thea & Amanda measured the change in the distance to the water level from the bridge going to the lower level of the floating building.

Ben & Mariana used a similar technique from the bridge going to the upper level of the floating building.

Angela & Felicia measured the change in the height of the ramp going to the docks.

  

Karam & Helen had a variety of clever ideas…

.

Mohamed & Chris did eventually manage to untangle the measuring tape above then nailed it to a piling and recorded the change in water level relative to the tape.

Many creative methods resulted in data that were then graphed and compared to the prediction of tide heights for Pedder Bay over 48 hours from 17 to 19 February 2012.  (from http://tbone.biol.sc.edu/tide/tideshow.cgi?site=Pedder+Bay%2C+British+Columbia).
