Every day there is a story to be told. Today’s story is an old one about the great inhalation and exhalation of fresh Pacific draughts by the interior waterways of northern Southeast Alaska. Ever since the glaciers retreated enough to open up the passages between Cross Sound and Icy Strait, twice a day great volumes of water have rushed through, forced by the true global tidal wave circling the ocean basins of the world, raising and lowering the elevation of the water according to the gravitational pull of the sun and moon. This exchange also cools the air and brings in nutrients, while stirring up organisms from the depths. Seabirds, eagles, whales, sea lions, sea otters all benefit from the abundance of food.
