The White Sea is so called because the northern reaches are locked in ice for most of the year, but also because the limey sediment churns up during rainstorms and turns the waters white. There is very little traffic on the White Sea outside of fishing boats. The White Sea is very rich in fish and shellfish, producing food for much of Altamira. In the summer when the waters are open, icebergs commonly float down from the northern reaches. On rare occasions, these icebergs have been found to contain ancient and wondrous treasures frozen in their depths. No one yet knows their source, but some treasure hunters have been known to ply their living prospecting the icebergs of the White sea hoping to strike it rich.
