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


NetworksFirst 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 States28 Countries operate floats, and Argo is reaching new record with 3918 active floats.


Member StatesActually 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


AgeFloat 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


AgeSpatial 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°


Density/Age vs Plans


Deployment Plans ScoreUse teh follwoing map to optimize your deployment locations if required.


PlansPlease 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


ProfilesDelayed 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 ».
