האי אומגהאנגלית: Omega Island) הוא אי, שנמצא בסמוך מדרום לאי אטא שבאיי מלכיאור בארכיפלג פאלמר, שלמול חוף חצי האי האנטארקטי שבאנטארקטיקה[1].

אורכו של האי 3.7 קילומטרים[1].

היסטוריה

גילוי האי

האי התגלה על ידי משלחת החקר הגרמנית בפיקודו של אדווארד דאלמאן[2]. דאלמאן לא נתן לאי שם[2].

האי התגלה מחדש ומופה באופן גס על ידי המשלחת הצרפתית האנטארקטית בפיקודו של ז'אן-בטיסט שארקו מחיל הים הצרפתי[2]. לימים התברר כי האי שכונה על ידי שארקו "האי מלכיור" ( Île Melchior) הוא למעשה שני איים - האי אטא והאי אומגה, והשם מלכיאור הפך לשמה של קבוצת האיים כולה[1][2].

קבוצת איי מלכיאור, ובהם גם האי אומגה, מופתה חלקית בשנת 1927 על ידי אוניית המחקר "דיסקברי" במסגרת סקרי דיסקברי[1][2].

האי מופה פעמים נוספות על ידי משלחות ארגנטינאיות ב- 1942, ב-1943 וב-1948[1][2].

מקור השם

בדומה לאיים אחרים באיי מלכיאור, לאי ניתן שם מהאלפבית היווני והוא נקרא על שם האות אומגה, על ידי משלחות המיפוי הארגנטינאיות[1].
