Recovering Argo Floats - N.Poffa - M.Amice.docx

Hi folks,
Just a word to let you know we're working on a new software VirtualFleet-recovery to help floats recovery.
The goal of the software is to provide a prediction of where Argo floats will surface after a given cycle.
It's all in here: https://github.com/euroargodev/VirtualFleet_recovery

How can OceanOPS help to recover floats ?

-Once a float is identified "OK to recover" the metadata "Retrieval status" should be set to "To Recover" in OceanOPS, that would help to inform all float operators and also follow those floats and use OceanOPS tools, maps, stats, etc..

-On 08/04/2021, 129 floats are tagged "To recover" but most are long time gone.. Victor maybe could clean this up ?

-OceanOPS cruise tool may be used to find potential cruises against floats "To recover" ?

-Additional tools on OceanOPS could help ? Live AIS data could be plugged in gor instance ?

Accessing highly accurate floats GPS position may not be always possible.
Should we consider adding an AIS to Argo floats ?
AIS could be the easiest way for any passing by boat to be aware that a float is requesting recovery and its location

How can we make float recoveries work with internationnal regulations ?

-Recoveries in EEZ
-Authorizations
-Customs situation once float recovered

etc, etc...

Hi guys,

I think we have to choose unique criteria to collect Argo floats. That is, what will be the parameter that gives us information to collect an Argo float? So far, I have been considering 300 work cycles as the limit to recover an Argo buoy.

I have the feeling that little by little the average life of the profilers increases every year, and therefore they are able to work longer at sea. Do we choose a limited number of work cycles to decide whether to recover a float or not? Perhaps a limit of voltage? @Martin-ifr suggested that a profiler is already profitable (cost per cycle) a few cycles before its final work cycle. I think @RomainCancouet shared that information at some point in a meeting, can you confirm @RomainCancouet? However, as Martin said, picking up one profiler and launching another on the same site is a win-win.

Once we decide this, we will have more options to work properly.
