The beginning of this week was dedicated to grain size surveys on the beach at the Elwha delta. What that means is that I got up early each day and spent hours taking photos of the ground. To spice things up a bit I decided to try something that I've been thinking about for some time - creating a time lapse of the rising tide. I've got some kinks to work out (need a bigger SD card, for example, since mine filled within 6 hours taking a shot a minute) but the result is very cool. More importantly, it may help me to get at some things I've wondered about, like how wave height and breaking characteristics change as the tide rises over the low tide terrace. We've also talked about using a similar technique to monitor changing grain size and shoreline position. Probably more of this to come.
