近年来海洋温度的变化影响了全球海洋生态系统的功能。然而，这些响应依赖于温度变化的速率和季节变化，这是空间可变的。对25年来的海表温度观测数据进行了严格的统计分析，以检查大加勒比地区总体和季节性温度趋势的空间变动性。该盆地的温度变化率具有很高的空间变异性。大部分变暖是由于夏季气温的升高，而不是冬季气温的升高。然而，冬季在环海流区和加勒比海东南部变暖更快，那里的年温度范围已经缩小。佛罗里达、古巴和巴哈马的海域在冬季有变冷的趋势，增加了年温度变化的幅度。这些详细的模式可以用来阐明该地区对气候变化的生态响应。(C) 2012 Elsevier Ltd.版权所有。
Recent changes in ocean temperature have impacted marine ecosystem function globally. Nevertheless, the responses have depended upon the rate of change of temperature and the season when the changes occur, which are spatially variable. A rigorous statistical analysis of sea surface temperature observations over 25 years was used to examine spatial variability in overall and seasonal temperature trends within the wider Caribbean. The basin has experienced high spatial variability in rates of change of temperature. Most of the warming has been due to increases in summer rather than winter temperatures. However, warming was faster in winter in the Loop Current area and the south-eastern Caribbean, where the annual temperature ranges have contracted. Waters off Florida, Cuba and the Bahamas had a tendency towards cooling in winter, increasing the amplitude of annual temperature ranges. These detailed patterns can be used to elucidate ecological responses to climatic change in the region. (C) 2012 Elsevier Ltd. All rights reserved.
