自世纪初以来，由于海洋观测系统的发展，人们对气候变异性的认识有所提高。随着阿尔戈剖面浮标覆盖范围空前扩大，地球能源收支可能会停止，这些浮标现在提供了十年（2006-2015年）关于2 000米以上海洋热含量变化的宝贵信息。从Argo和重复水文剖面获得的专业知识促使阵列向海底延伸，这将逐步揭示鲜为人知的深海，并减少其对2006-2015年全球海洋变暖趋势0.65-0.80 W m（-2）的10- 15%贡献的不确定性。各种观测系统的可持续性和协同作用有助于证实数字模型，并解释不同海洋盆地的内部变化。由于对北大西洋环流的独特观测，特别注意热含量的变化及其与该地区动态变化的关系。
Since the early twenty-first century, improvements in understanding climate variability resulted from the growth of the ocean observing system. The potential for a closure of the Earth's energy budget has emerged with the unprecedented coverage of Argo profiling floats, which now provide a decade (2006-2015) of invaluable information on ocean heat content changes above 2000 m. The expertise gained from Argo and repeat hydrography sections motivated the extension of the array toward the ocean bottom, which will progressively reveal the poorly known deep ocean and reduce the uncertainty of its presumed 10-15 % contribution to the 2006-2015 global ocean warming trend of 0.65-0.80 W m(-2). The sustainability and synergy of various observing systems helped to corroborate numerical models and decipher the internal variability of distinct ocean basins. Due to unique observations of the circulation in the North Atlantic, particular attention is paid to heat content changes and their relationship to dynamic variability in that region.
