Activity
With 3473 floats the activity indicator for the core Argo array is 108%

Networks
First deep Argo floats (ARVOR_D, NINJA_D, SOLO_D) are operating

Density (core)
56% of the core array is well (or over) sampled

Density/Age (core)
49% if we consider decimal floats (weighted by their probability to die)

Density/Age (core)
Spatial analysis allows to identify hot/cold spots and highlight gaps.
Below 45°S in Indian and Atlantic in particular.

Member States
28 Countries operate floats, and Argo is reaching new record with 3918
active floats.

Member States
Actually more than 150 additional floats are registered but no data is
available yet. Argo has certainly more than 4000 units in the ocean.

Member States (zoom)
France just the 2nd float operator after USA.

Market

Market
« New » float manufacturers (SBE and NKE in particular) keep increasing their
market.
Iridium (and BioArgo) seem stabilizing

All Deployments (<2015)

New Floats (2015)

All Deployments (<2016)
750 units deployed so far in 2015

Age
Float age distribution (in years)

Age (inactive floats)
All inactive floats deployment locations by age class indicating how long
float perform according to their launch location.

Age (inactive floats)
Spatial Analysis
We can try identify cold/hot spots where floats seem surviving shorter
(blue - marginal sreas, high latitudes) or longer (red -Karahoa
deployments ?)

Kaharoha’s contribution
~20% of the active Argo array is implemented by one NZ ship (charter)

Age

Age
Spatial analysis to detect geographical hot/cold spots. Blue or young zone
vs red/old zone.

Density (SIO)
Percentage of the density upon full implementation by Scripps

Density 6° x 6°
For the Global array, southern ocean remains the challenge

Density/Age 6°x 6°

Plans
Please provide yoru draft plans as soon as possible and in any format.
Standrda JCOMMOPS txt format is gradually used by all programmes:
ID (any);WMO (if exists);LAT;LON;DATE;SHIP;CRUISE

Profiles
Delayed mode quality control still remain a challenge (% achived keeps
decrfeasing slowly)

Profiles Quality (Sep. 2015)A quick virew on 2015 3rd quarter profiles quality.
90% of profiles produced are « good ».
