海洋是地球气候系统中的主要储热库，吸收了大部分大气层顶部的过量辐射。随着气候变暖，在南极洲附近形成的深海层中异常温暖和新鲜的海洋沃茨通过深海向北扩散，而在格陵兰附近形成的深海层中则出现了一系列的变暖和变冷事件。深海变暖和淡化扩大了海洋体积，提高了海平面。虽然对2 000米以上海洋沃茨的温度和盐度特征以及大规模环流进行了很好的监测，但目前的海洋观测网络受到2 000米以下深海取样稀少的限制。最近开发的自主机器人平台Deep Argo浮标收集从海面到海底的剖面。这些仪器补充了卫星、Core Argo浮标和船基观测，以测量整个海洋体积中的热量和淡水含量，并关闭海平面预算。在这里，深Argo的价值和计划的战略，以实现全球阵列的描述。Deep Argo的其他目标可能包括溶解氧测量，以及海洋混合和光学散射传感器的测试。还介绍了使用Deep Argo测量数据开发新兴海洋测深数据集的情况。
The ocean is the main heat reservoir in Earth’s climate system, absorbing most of the top-of-the-atmosphere excess radiation. As the climate warms, anomalously warm and fresh ocean waters in the densest layers formed near Antarctica spread northward through the abyssal ocean, while successions of warming and cooling events are seen in the deep-ocean layers formed near Greenland. The abyssal warming and freshening expands the ocean volume and raises sea level. While temperature and salinity characteristics and large-scale circulation of upper 2000 m ocean waters are well monitored, the present ocean observing network is limited by sparse sampling of the deep ocean below 2000 m. Recently developed autonomous robotic platforms, Deep Argo floats, collect profiles from the surface to the seafloor. These instruments supplement satellite, Core Argo float, and ship-based observations to measure heat and freshwater content in the full ocean volume and close the sea level budget. Here, the value of Deep Argo and planned strategy to implement the global array are described. Additional objectives of Deep Argo may include dissolved oxygen measurements, and testing of ocean mixing and optical scattering sensors. The development of an emerging ocean bathymetry dataset using Deep Argo measurements is also described.
