After finding a multitude of washed up garbage and plastic
at Fernandina Beach (see previous post titled "Plastic Jackpot"), I
figured I was in fact on to something and Florida's east coast does have more
plastic content-possibly due to the North Atlantic Garbage Patch- than the west
coast.
However, my next stop on the east coast, on October 6th, 2013,
was disappointingly clean and beautiful. On the other beaches I noticed each
being used as a giant ashtray; Marineland's beach had ONE cigarette butt!
During my visual survey I came across one plastic bottle,
about 12 inches long, made of dense looking blue plastic, that had what looked
like bivalves growing on it but hermit crabs seemed to live in them:
Back on Fernandina beach I had decided to change my
procedure a little bit. The first time I went out for samples (see blog entry
on "Realization: Maybe lab work would suit me best"), I took down the
GPS coordinates of every sample I scooped, however, all of it ends up mixed up
in the same jar and the instrument I am using has around a 20 foot error.
Instead, I now take down the starting and ending GPS
coordinates, and changed my sampling parameters to the following "whichever
comes first" limits:
- 1 hour
- 1/2 mile
- Filled 2 quart jar
Ultimately I only took surface sediment samples from
Marineland's beach, however, in hindsight, since that dense looking blue bottle
was too big for my jar, not taking it home with me might come back to haunt me.
Originally I had planned on tracking the number of plastic pieces found in each
location, which is technically at this point 1 piece for Marineland' beach,
however, if it turns out I have a handful (hundreds) of microbeads in my sample
it would probably be easier to quantify my plastic findings by weight instead
of number of pieces.
Excellent job, Angela! You are certainly involved in the process they call "science"--complete with new realizations and adjustments to methodology. You're doin' great!!
ReplyDeleteI know several of us have said this before, but it IS really nice to be able to make mistakes, admit to them, and learn from them stress free.
DeleteAngela--may I use your comment in my Hawaii presentation?--this type of statement is an important point when teaching this lab.
DeleteOf course!
