There is a case study of ARGO buoys possibilities for Arctic Ocean scientific investigations with innovative ocean technologies on the base of geospatial measurement and information systems that are part of decision support systems. The compiled data base of some ARGO buoys (DB ARGO) penetrated into arctic and subarctic waters from Atlantic (DB ARGO ATL) developed. It is intended to research the patterns of Atlantic Waters penetration into the Arctic Ocean. One of these buoys had unique long Odyssey from warm waters near southern coast of Nova Scotia to high latitude arctic area near northern cap of Novaya Zemlya. This trip began 2008 summer and lasted near five years. Over 180 vertical profiles of temperature and salinity provided with 10 days interval and transferred to ARGO Data Center. Over year this buoy moved inside depth of Barents Sea dragged by Atlantic Waters. It crossed area of Stockman gas-oil field in 2012 and then came to northern cap of Novaya Zemlya where ended functioning at 2013 early spring. Till now it is the only ARGO buoy trip in the Barents Sea. The measurement results obtained during this drift indicated a significant inflow of atypically warm Atlantic Waters into high latitude area between Franz Josef Land and Novaya Zemlya. It was accompanied by later dates of ice appearance in this area. This case study clearly demonstrates the ARGO buoys resources for Arctic Ocean scientific investigations including patterns and scenarios of climate change for Arctic with Atlantic Waters engagements. Resources of internet platform https://www.researchgate.net/profile/Valery_Abramov2/?ev=hdr_xprf were used for wide preliminary discussion and data exchange in the frame of this research. Here we used data that was collected and made freely available by the International Argo Project http://www.argo.net and national initiatives that contribute to it. Argo is a pilot programme of the Global Ocean Observing System. The Ministry of education and science of Russia provided financial support for this research with the state order 2014/166 and state contract 14.515.11.0002.
