Info

A sticker describing Argo and PI information in Japanese is attached to floats deployed around Japan. However, Argo floats are not very well known among Japanese fishermen or local Coast Guard offices. To inform them about the Argo floats, JAMSTEC and the Japan Coast Guard made a leaflet about Argo floats (in Japanese). The leaflet describes (a) purpose of the Argo program, (b) characteristics of Argo floats, highlighting its non-explosive nature and (c) contact point/person. Most important message is “Argo floats are not dangerous objects” because the shape of floats tends to give an impression that it is something dangerous. The leaflets were distributed to local Coast Guard offices to inform the public about Argo floats. Smooth communication between finders and owners of floats should be facilitated in order to prevent possible trouble between them. However, the procedure to handle beached Argo floats is still not agreed upon among relevant government agencies/institutes in Japan. Discussions about this matter are ongoing to avoid any trouble that may arise. Action item 5: If a beached float has been reset and is to be redeployed, a new WMO ID needs to be assigned to the float and it needs to be re-notified. If the float has not been reset, it is permissible to redeploy the float with the same WMO ID.

After the project was over in 2004, part of its framework such as a “liaison and 13
coordination committee” has been sustained, which facilitated Japanese contribution to the core Argo. However, lack of effective mechanisms to define new clear objectives of Japan Argo tended to cause vulnerable funding situation especially after the “completion” of the 3000 float array. In 2010, two forums were held to build consensus on the future direction of Japan Argo among scientists, governmental officers and relevant private sectors, following the vision built as an outcome of OceanObs`09. The consensus on the future of Japan Argo developed by the forums is summarized as follows. 1) Japan Argo should continue to contribute the core Argo by sustaining current level of float deployment and data management activities. 2) Japan Argo should contribute to construct new integrated ocean observing systems, based upon the Argo core array, which will increase the climate monitoring and research capability and provide information on the marine environment to meet society’s needs better. As part of efforts in line with the consensus above, in 2011, JAMSTEC will start a project on regional integrated ocean observation, “Western North Pacific Integrated Physical- Biogeochemical Ocean Observation Experiment (INBOX)”. The purpose of this project is to investigate effects of mesoscale variabilities on biogeochemical processes by acquiring physical – biogeochemical parameters intensively in space and time in the western North Pacific. Twenty-five dissolved oxygen floats will be deployed as Argo equivalent floats in the experimental area of 150 km x 150 km in collaboration with other observational platforms such as moorings, ships and satellites. 4.9 BioArgo update In 2008, the International Ocean Color Coordinating Group (IOCCG) launched the Bio-Argo working group. Its general objective was to make recommendations in view of implementing optical sensors on profiling floats as a way to increase in situ data acquisition of bio-optical / biogeochemical variables with the ultimate aim to develop synergetic applications with remote sensing of ocean color. The overarching goal of this effort is to obtain a better understanding of biogeochemical cycles at a regional and/or global scale and of their evolution under a changing climate. Additional goals are to provide more synoptic data to ecosystem modeling activities (data for initialization, validation and assimilation), improve the coverage of ocean color by adding a depth dimension, and providing quality data to evaluate ocean color remote sensing and products derived from it. As a result of two meetings attended by scientists from complementary expertise with respect to this emerging field, the Bio-Argo WG submitted its report to IOCCG early this year (it should be published within the next few months). Three main classes of bio-optical and / or biogeochemical floats have been proposed. The Val-float is totally dedicated to Calibration and Validation activities for Ocean Color satellite sensors. The emphasis is put in particular on the radiometric package (downward irradiance and upwelling radiance and on spectral resolution). 14
