摘　　要：早期研制的Apex型剖面浮标,由于浮力有限,不适合在上下层密度差较大的低纬度海区使用。为了实现国际Argo科学组提出的"要获取全球大洋2 000 m水深剖面资料"的目标,从2004年开始,美国Webb研究公司组织技术研究人员对普通Apex型浮标进行了技术革新,从而使得今天已经建成的全球Argo实时海洋观测网具备了覆盖全球大洋进行2 000 m水深剖面观测的能力。美国华盛顿大学海洋学院Stephen C.Riser教授专门著文详细介绍了这一改进技术,我们对全文进行了翻译和整理,以供国内浮标技术研制人员参考。In 2000, the Argo Science Team decided that Argo floats should be parked at the depth of 1000 m and should profile from 2000 m to surface, anywhere of the world oceans whenever this was technically feasible. Most Argo floats can carry out this profiling specification. However there are still parts of the world oceans where profiling from 2000m to the sea surface is difficult or impossible, especially at low latitude within about 15° of Equator. Because the water density between 2000m and sea surface has a maximum change near Equator, which limits the use of the earlier developed Apex floats. In order to save this problem, engineers in Webb Research Corporation began to design a prototype APEX float in 2004, which now is able to meet the need to operate at low latitude in the world oceans. Up to now, the Argo floats have almost covered worldwide. Prof. Stephen C. Riser in the University of Washington wrote an article： Profile to 2000m anywhere in the World Oceans： Advances with APEX Floats, which is helpful to researchers who are related to float technology.
