I echo Greg Rau's comments. Good idea to do something, but plastic? Really?
I looked at this in 2005 and wrote a piece on aerosol screening the Arctic

The Economist Magazine has a special report this week on the warming of the
Arctic Ocean.
The report is available at http://www.economist.com/node/21556798 and is highly
informative.

Despite their spectacular visibility, Arctic blooms absorb light as well as
backscattering it in ways more complex than microbubbles.
It is by no means clear what water temperature changes the interplay of
backscattering, undershine, and evolving population density will yield, for
dissolved
In terms of nature's little geoengineers, and hoped-for negative feedbacks
in the arctic, there might also be some neighborly natural SRM
going on under the arctic ice alongside the natural CDR described in this
posting. At Los Alamos there's been some interesting modeling of sea-ice
edge

Am I right to be concerned, or am I just ignorant of the literature?
Regarding ocean albedo: I think this is true.
The state-of-the-art ocean (CMIP5) climate models of which I am aware
prescribe ocean albedo based on wavelength, zenith angle, and the
direct/diffuse distinction, and neglect
Guess I'd be a little more cautious about these observations being a good
thing. If widespread: organic loading at depth, anoxia, NOx and CH4
generation? - G
