Okyanuslar\u0131n ve denizlerin bu d\u00f6nemsel (periyodik) kabarma ve al\u00e7almalar\u0131na yani gel-git olay\u0131na, bir de gel-git ak\u0131nt\u0131lar\u0131 ad\u0131 verilen yatay su hareketleri e\u015flik eder. Bu ak\u0131nt\u0131lar, okyanuslarda, k\u00f6rfezlerde ve hali\u00e7lerde (\u0131rmaklar\u0131n denizlere a\u00e7\u0131lan a\u011f\u0131zlar\u0131nda) kendini g\u00f6sterir. Gel-git ak\u0131nt\u0131lar\u0131 g\u00f6ller de de vard\u0131r; ama oralarda o denli hafif olurlar ki, etkileri \u00f6nemsenmez.<\/p>\n
Gel-git ak\u0131nt\u0131lar\u0131 da suyun kabarma ve al\u00e7almalar\u0131na ba\u011fl\u0131 olarak periyodiktir.
