This is just a more expensive variant of the papers from Songjian Zhou and Peter C. Flynn, they use submarines instead of snow-guns. Zhou, S., & Flynn, P. C. (2005).

They don't produce "icebergs", but "sea ice". Might be better not to fill all the space, but to let holes in between the hexgonal sea-ice puzzle structure, in order to enhance longwave radiation from the ocean to the space, as ice acts as an insulator. *CDR *=> Zhou, S., & Flynn, P.
