A prototype Deep Argo float

Argo Floats monitor the ocean to the depth of 2000m. This is fantastic- but really only about half the ocean. With the advance of technology, we are able to keep a pulse on even more of our ocean with these new Deep Argo Floats.
These floats look completely different. They use a glass sphere as the pressure housing rather than the usual aluminum cylinder, and they can go to depths up to 6000 m!! Dean was talking about these in his interview a couple of years ago - it's now happening!


In June 2014, several Deep Argo floats will be deployed off the RV Tangaroa, northeast of N.Z. and calibration tests will be carried out with a new CTD built especially for Deep Argo.

Video footage from CalCOFI shows the Jan. 24, 2013 deployment of a Deep SOLO prototype. The instrument could soon complement floats used in the global Argo network, an array of 3,500 instruments in the world's oceans that afford scientists an unprecedented record of basic conditions in all ocean basins simultaneously. Deep SOLO uses a similar pump to Argo floats, but is housed in a glass sphere rather than in an aluminum cylinder in order to be able to dive to depths as great as 6,000 meters (19,700 feet). It is designed by Jeff Sherman, Russ Davis, and David Black of the Scripps Instrument Development Group. Upper-ocean Argo floats measure seasonal, interannual, and decadal variability, while the deep array will be more focused on decadal signals, said Argo scientist Dean Roemmich. (Used by permission)
