Recent data suggest that, contrary to prevailing views, there are pathways for near surface currents around the Peninsula to the west. If proved, these would be important for the retention and/or dispersal of krill larvae and other passive drifting particles. The Antarctic Slope Front appears to lose its properties as it enters the Weddell Scotia Confluence. The ADELIE project will deploy 20 surface drifters and 4 Argo floats near the Antarctic Peninsula. The surface drifters are designed to follow the ocean current and will telemeter their position back via satellite several times a day. The Argo floats are designed to float deep in the ocean, at about 1000 m, following the current there. Every 10 days they come up to the surface, measuring temperature and salinity as they go, and telemeter their location and the profile data back via satellite. These floats and drifters will span the Antarctic Coastal Current and Antarctic Slope Front. A section of temperature and salinity across these flows will indicate their locations and quantify their strength. Their pathways will be mapped for the first time. The influence of bathymetry controlling the splitting and steering of these frontal jets will be studied. Output from eddy resolving ocean models (some with sea ice) will be analysed and virtual drifters deployed in their flow fields.

最近的数据表明，与流行的观点相反，半岛周围的近地表水流有向西流动的途径。如果得到证实，这些对磷虾幼虫和其他被动漂流颗粒的滞留和/或扩散将是重要的。南极坡锋在进入威德尔-斯科舍合流时似乎失去了它的特性。阿德利项目将在南极半岛附近部署20艘水面漂浮器和4艘Argo漂浮器。海面漂流船的设计目的是跟随洋流，每天几次通过卫星遥测自己的位置。Argo浮标的设计目的是在海洋深处，大约1000米的地方，跟随洋流漂浮。每隔10天，他们就会回到海面上，测量温度和盐度，并通过卫星遥测他们的位置和剖面数据。这些漂浮物和漂浮物将跨越南极海岸流和南极斜坡锋。这些水流的温度和盐度剖面将表明它们的位置并量化它们的强度。它们的路径将首次被绘制出来。研究了水深测量对射流劈裂和转向的影响。将分析涡旋解析海洋模型（有些带有海冰）的输出，并在其流场中部署虚拟漂移器。
