Winter in Alaska is the time of ice, when the sun slips to the south and the
darkness grows, and the earth freezes. But those who live here know that there
are moments of great beauty in the cold of winter; that ice can glow like diamonds
when lit by the sun. Photographer Hal Gage has lived in Alaska his whole life, the
son of a jeweler, now showing his own collection of gems discovered in the ice.
But unlike diamonds, which we are told are forever, ice is ephemeralŕgrowing in
the cold ...

This warmer water retards the growth of ice around dam piers, gate seals, and
gate structural elements. This solution works better in deeper water where even
minor temperature stratifications exist. In shallow areas, such as most river
navigation channels, the water body is fully mixed and there is not enough
warmer bottom water for this technique to be effective. • Ice passage gates are
either spillways or gates specifically designed for passing brash ice from the
upper lock approach ...

clothing—to each of our company, so that we might be ready to meet the ice.
Most of us had also procured sealskin clothing by barter. On August 6th we were
abreast of Upernivik, 12 miles off. Here hundreds of icebergs had collected. They
looked larger and more compact than those we met to the south. Of drift ice we
had not yet seen a trace, and we began to entertain the hope of slipping
unhindered across Melville Bay. The day after we passed Itivdliarsuk in latitude
73° 30' N ., the ...

That exploration, under my command, charted a top-of-the-world, under-ice
passage between the Pacific and Atlantic Oceans by way of the North Pole. But
our book was necessarily incomplete. Most of what actually happened remained
hidden to public eyes— highly classified—for years afterward. Security concerns
prevented us from revealing the most interesting features and capabilities of our
nation's first nuclear submarine. We included very little background information

There are many unsettling issues facing the countries of the world, and especially
Canada, concerning the future of the Northwest Passage in this time of melting
ice caps, glaciers and sea ice in the Arctic. Canada in particular has a high stake
in the foreseeable opening of the Passage to commercial navigation. There are
estimates ranging from less than twenty years, and up, as to when the ice in the
Passage will be thin enough to permit maritime traffic on an economic basis. The

ternarked, that the ice was all pure and transparent, except the upper surface,
which was rather ' porous.' And as the philosophers of the north have assured us,
that pure transparent ice projects one tenth, as it swims in the sea, even this part
of the ice must have been immersed to within 12 fathoms of the bottom: but Cook
observes, ' further to the northward it seemed to be much higher ;' and in all
human probability, the ice at no great distance to the northward, beyond what he
saw, ...
