Annual cycle of sea level height: The annual cycle of sea level height (or seasonal cycle or annual harmonic) describes the variation of sea level that occurs with a period of one year.  Historically, analysis of the annual cycle has been limited by locations with tide gauge records, i.e., coastlines and some islands in the deep ocean, and by sparse records in the Southern Hemisphere.  Since 1992, satellite-based altimeters have provided near global coverage of sea level variability, allowing for a more thorough understanding of the annual cycle both in the deep ocean and in coastal margins.

Lietuvininkai we are born: Lietuvininkai we are born (German: "Als Litauer sind wir geboren" , Lithuanian: "Lietuvninkai mes esam gimę" ) is a Lithuanian-language patriotic and sentimental poem written by the German linguist Georg Sauerwein in 1879.  It is a passionate defense of Prussian Lithuanian (Lietuvininkai) language and culture, rallying people to resist Germanisation attempts.  However, at the same time the poem proclaimed love and loyalty to the Kaiser signifying that the rally was cultural and not political.  It was inspired by Enlightenment ideas that archaic languages and traditions of minorities should be cherished, studied, and preserved.  The poem was first published in the Prussian Lithuanian newspaper "Lietuwißka Ceitunga" in 1879.
