Agulhas海流是一个快速的西边界流，沿着南非东海岸流动，强烈影响邻近的夸祖鲁-纳塔尔陆架的海洋学变化。2010年1月，2010年7月和1989年7月的水文观测已被用来描述地转流和水团的变化，并阐明环流和温盐结构的变化机制。风强迫，降水和太阳辐射的差异造成的分层和混合，导致在季节性变化的表面温度，盐度和混合层深度ZMLD之间的南方夏季和冬季调查的修改。在2010年1月，表面温度升高，并有一个大的盐度范围为10米以上的河流流出和降雨的影响。2010年7月和1989年7月，表层温度较低，盐度范围明显减小。2010年1月的ZMLD较浅，变化在5 - 40 m之间，而深度在10 - 20 m之间。
AbstractThe Agulhas Current is a fast western boundary current flowing along the South African east coast, strongly influencing oceanographic variability on the adjacent KwaZulu-Natal shelf. Hydrographic observations in January 2010, July 2010, and July 1989 have been used to describe variations in geostrophic currents and water masses and to elucidate mechanisms of change in circulation and thermohaline structure. Differences in wind forcing, precipitation, and solar insolation caused modifications in stratification and mixing that resulted in seasonal changes in surface temperature, salinity, and mixed layer depth ZMLD between the austral summer and winter surveys. During January 2010, surface temperatures were elevated and there was a large range in salinity as the upper 10 m was influenced by river outflow and rainfall. In July 2010 and 1989, surface temperatures were lower and the salinity range was significantly less. The ZMLD in January 2010 was much shallower, varying between 5 and 40 m, while dee...
