The Integrated Marine Observing System: observing Australias - - PowerPoint PPT Presentation
The Integrated Marine Observing System: observing Australias changing oceans Katy Hill Tim Moltmann, Roger Proctor, Marian McGowen Greenhouse 2011, Cairns, Australia. Outline Motivation for an Integrated Marine Observing System
– Multidecadal ocean change – Climate variability and weather extremes – Boundary currents and inter-basin flows – Continental shelf processes – Biological responses
influenced climate
– drought, flood, extreme events
from ocean territory
– marine tourism, oil and gas, shipping, fishing & aquaculture
significant conservation value
– from the high tropics to Antarctica
– ecosystem services, recreation value
great opportunity for the Australian people
challenge...
understand and manage such a vast ocean territory, with a relatively small population

patterns in biomass
– Yongala is the lowest. – Port Hacking is leading the country.
– zeaxanthin (Synechococcus) is about 20 times more abundant at Yongala than Maria. – Photosynthetic dinoflagellates (peridinin) are most abundant at Kangaroo Island. – Coccolithophorids (19 hex) are widely present but most abundant at Esperance. – Chlorophytes (chlb) are most abundant at Maria.

From Ian Field
– ...the recognition of data and information as infrastructure, is central for some capabilities. – The observation-based capabilities such as IMOS...are providing continuous data streams of critical information about processes that operate on long time scales, such as ocean-climate dynamics... and that lead to understanding of climate change or natural hazards. – Ongoing support for these data streams is essential to maintain the value of the

– A task which cannot be underestimated! – Important that we demonstrate its utility, and critically assess what science it is enabling.
