Abstract
TWO important papers on the tides in small seas have recently been published by the Vienna Akademie der Wissenschaften. The first, in Bd. 96 of the Denkschriften, is the latest of a series of researches by R. Sterneck, jun., on the tides of the Adriatic; the second, in Bd. 129 of the Sitzungsberichte, is the sixth part of A. Defant's researches on tides in “Mittel- und Randmeeren, in Buchten und Kanalen,” and concerns the tides of the Irish Sea. Both investigations are applications of hydro-dynamical principles, assuming from observation just sufficient to give or replace the “boundary conditions” where the sea communicates with the larger body of water. Both treatments depend on the elongated nature of the sea in question and utilise charts of soundings after the manner initiated by Chrystal for the longitudinal seiches of lakes. Defant makes separate applications to the Bristol Channel, Liverpool Bay, and Solway Firth. In each case the assumed type of motion may be regarded as a longitudinal oscillation sustained by the tides outside, together with a transverse gradient maintained by the longitudinal current in virtue of the earth's rotation.
