Louis, Missouri, during the snow period with a snow-related injury, while patients were seen for ice-related injuries at the same hospital during the ice period
(p less than 0.05).
Many of his most successful designs are still in production, his dimpled, chunky bottle for Finlandia vodka, in use from 1969 to 2000, may be the best-known design of his ice period

This conjecture, of course, does not mean that a decrease in the length of the ice period
would lead to smaller overall wave loads to the coast.
On test lakes--some vast and deep, others less than 500 acres with no more than 40 feet of water-he founded 8 to 16 ppm (parts per million) of dissolved oxygen in 1-to-10-foot zones, all through the darkest, thickest ice periods
. For perspective, 4 ppm is enough to sustain most freshwater fish including highly sensitive ciscoes, whitefish, and lake trout.
In all three regions, the patterns of variation in stranding rates between `open' and `restricted' summer sea ice periods
are remarkably similar to those derived from radiocarbon dates (Table 1 and Figs.
