05.07.11: Analysis of 5145, 6401, 6891 and 6403 ARGO floats - an update

We update and complete the basic analysis of ARGO floats started in this note and updated in this note.

The trajectories are shown in Fig. 1.

Figure 1: Trajectories of the ARGO floats: up to Sept. 2010 for 5145 and May. 2011 for all others.

The potential density σ (referenced at the surface), the Brunt-Vaisala frequency (BVF) and nitrate (NTR) are plotted in Figs. 2 to 5 for each of the float.
