IMOS National Working Group on Bio-optical Instrumentation and Observing

Argo floats fitted with Biogeochemical sensors

Background and Rationale

Bio-optical instrumentation is a key component to a number of IMOS facilities, and is critical to the goal of increasing our understanding of physical-chemical-biological linkages in coastal and oceanic Australian waters.  Unlike standard physical measurements such as temperature and salinity, the calibration, validation and interpretation of data generated by these bio-optical instruments is not necessarily straight forward.  Similarly, best use of these data in a national program across multiple facilities and for multiple uses requires nationally co-ordinated efforts. 

To progress these issues, IMOS has supported the formation of a national scientific Working Group (WG), with the broad mandate of tackling issues of national relevance related to bio-optical measurements and interpretation.   The WG brings together experts in various fields related to these goals, and will operate across the various IMOS Facilities and Nodes.  As IMOS operates nationally, the WG model is suggested as an efficient and focused way to build a broad consensus and capability on these matters, with the longer term view to developing and sustaining a Bio-Optical Community of Practice within IMOS.


Working Group Terms of Reference

1) Develop an integrated and scientifically robust strategy for the calibration, validation and interpretation of single-waveband fluorescence, absorption and scattering data, as collected by a number of IMOS facilities

2) Review and advise on priorities for incorporating more advanced bio-optical instrumentation within IMOS facilities

3) Facilitate and improve links from bio-optical data streams to biogeochemical models

4) Advance integration of in situ bio-optical observations and satellite remote sensing, including strategies for the development of inter-calibration protocols and exercises

5) Work towards building a national bio-optical Community of Practice
