TRANSCRIPT

WA – IMOS: Application of IMOS data on the western and northern coasts

Gary Kendrick, Ming Feng, Patrick Seares, Steve Rogers, Rob McCauley, Chari Pattiaratchi, Agi Gedeon

IMOS is supported by the Australian Government, through the National Collaborative Research Infrastructure Strategy and the Super Science Initiative

IMOS data portal

Western and NW Australia - Knowledge Needs (WAMSI Patrick Seares)

1. An applicable knowledge of currents, oil/water column dynamics, weather and environments between the petroleum precincts to the islands, reefs and coastline in the Kimberley, Exmouth and South Coast regions to underpin future decades of offshore and coastal industry operation - development

2. Where are large marine wildlife moving, breeding and feeding and where does it intersect with current and proposed human activity

3. How will changes in the ocean currents and marine environment impact on the viability of current fisheries, development of new fisheries (and aquaculture), tourism, and marine park/reserve values over coming decades

4. Increased accuracy of short-medium term rainfall forecasts for south-west land division

5. Inundation, sedimentation and erosion risk to coastal urban in Perth to Dunsborough region, Exmouth and on ‘Pilbara Cities’ expansion areas

6. The threats to marine parks, accuracy of marine park zoning, and trends in indicator species (priority on coastal marine parks where pressures are greater)

7. What are reduced cost indicators (oceanographic, biological, chemical, genetic) that can provide reduced cost monitoring of marine environments

8. What extent is suspended sediment, temperature and physical impact caused by natural events vs human activities for marine park areas near the Pilbara and south west

9. What is the biosecurity risk of current borne species from SE Asia reaching Australian/WA marine parks and fisheries

• Chevron for the Exmouth Plateau.

Links to Blue Water IMOS Moorings - Timor Sea Tides

Deep mooring: •Surface and internal-tide energy have similar magnitudes •Internal-tide energy follows the local spring-neap cycle. Shallow mooring: •Internal-tide energy is an order of magnitude smaller than surface tide energy •Internal-tide energy is only present after the 1st of September

Internal-tide generation on 5 DEC •Most generation occurs in the deepest part of the Timor Sea

Impediments • Ship time – annual budgets from multiple sources

• Data under-utilized – familiarization of IMOS data streams underway – WAIMOS Training –workshops underway

• Glider • Moorings • Remote Sensing

• Emi – data stream slow for some nodes • Not integrating data sufficiently

– Although starting to publish multiple streams e.g. Verspecht et al. submitted uses Hf radar, remote sensing, moorings off Perth WA

• Funding to continue WA investment

IMOS interactions: PROSPER and the Marine Science Blueprint

2050

The Fundamental Challenge In the absence of a mandate from Government, PROSPER will have to make an adequately compelling commercial (strategic, operational, financial, and/or SLO) case for industry to allocate resources and manage risk.

Low offshore asset density

Single dominant oil and gas operator owns most of the data

of value

Need for resource intensive data quality and service assurance

Concept fatigue

Strategic and Operating Context

Primary need for stakeholders is site specific data

Some scepticism as to what impact new knowledge will have

on the current operating paradigm

Limited compelling case for key stakeholders

End-user Need Issues

Opportunities for PROSPER Emerging Acceptance that Data Sharing May Prove

Beneficial

Greater Likelihood in Sharing Real-time Data than Longitudinal Data

Sets

Recognised Need to Improve Models

Harmonisation of Data Collection, Analysis

and Reporting Standards

Strong Interest from the Research Community

Current NOPSEMA Approvals Streamlining

Review

Baseline Data for Browse/Kimberley

As more E&Ps enter the region the case for sharing may become more compelling

There seems to be a greater willingness to explore the sharing or new data, rather than historical data

There is a recognition that existing metocean models pertaining to the NWS are dated and in some cases deficient

Heterogeneity in data collection and reporting standards is a challenge that PROSPER could address

There is strong interest in the proposed PROSPER capability from the scientific community

Will NOSPEMA’s approach to this issue change? Will data disclosure be an element of productivity improvement?

At least there is 30 years of operating experience in the NWS There is no experience in the Browse and ‘new’ technology is being deployed

Blueprint for marine science 2050

Common mission

Aligned priorities

Partnered resourcing

Blueprint for marine science 2050

Identify enablers

Resourcing strategy Collaboration

Define common priorities

Specific research and data Underpinning and regional research Capability and Infrastructure

Identify gaps that prevent achievement

Knowledge ‘Reality check’

Define ‘real’ needs for State and national prosperity

Economic development Environmental management

Blueprint for marine science 2050

• Led by science ‘end user’, informed by research

• A marine science strategy, not a WAMSI

strategy

• Regional detail to support Marine Nation 2025, IMOS strategy 2015-25, BoM strategy, etc

• Consultation process coming soon

(Recommends a decadal science plan)
