Blue Water and Climate Node
Pete Strutton and Steve Rintoul
With much help from the node
March 8th, 2016
Strengths
• Strong science of global relevance being published
in high profile journals
• Wide and growing uptake by research community,
including use of data by students, grad programs
• Facilities delivering high quality data
• Strong science plan with wide community support
provides a good foundation for strategic decisions
on priorities, challenges and opportunities
• Geographic advantage
• International recognition, ‘valued’
• Identifying and implementing efficiencies (doing
more with less)
Wijffels, Roemmich, Church,
Monselesan and Gilson, NCC, 2016.
Recent high profile publications
Liu, Q.-Y., M. Feng, D. Wang, and S. Wijffels (2015), Interannual variability of the Indonesian Throughflow transport: A revisit based on 30 year expendable
bathythermograph data, J. Geophys. Res. Oceans, 120, 8270–8282, doi:10.1002/2015JC011351.
IMOS XBT network: 30 year record
Strengths

• Geographic advantage
• International recognition
• Identifying and implementing efficiencies (doing

• Sloyan et al paper in press at JPO: Transport
analysis
• Assimilation of data into models
• Model-based assessment of multi-platform
monitoring, which can then feed back into the data
assimilation models
• Validation of a tidal model: ‘Bernadette did an
excellent job of cleaning up the data and it was
easy to use’
• Both EAC (Oct 2016) and ITF (Apr 2017) will be
redeployed
EAC array data uptake by community
Haifeng Zhang (UNSW in Canberra)
Monthly (day – night) SST for 2010 – 2014, compared with
monthly surface fluxes from ACCESS-R for the same period.
IMOS ship SST also used as independent satellite validation
Data uptake: Satellite SST for diurnal variability

161793 km of data since 2010
Mesopelagic Southern Ocean Prey
and Predators
EU project 2016-2019
6 countries with Australian
representation:
ACE-CRC, CSIRO, IMAS, AAD
Development of ecological models
using bioacoustics data
International engagement, regional advantage
International engagement, regional advantage
Over 70K IMOS CTD obs past 60°S
IMOS WOD 13 –ctdWOD 13- PFL
CPR ecosystem indicators
• Shiptime. Two year mooring deployments?
• Science return and piggyback projects can take
time. Excellent value-adding at SOTS and Totten.
• Prioritising regions or processes: Are we doing this
in the best way?
• Integration with regional nodes and across
disciplines improving, but could improve further
• Strong engagement with established blue water
community. Could do even more to entrain new
research user communities
• Contraction of support: Ability to deploy, QC, and
use data
Weaknesses
• Costs for some facilities (SOTS) may decrease
– May enable new projects without cutting existing
• New technologies
– Biogeochemical floats (eg SOCCOM), deep Argo
– Ice-capable floats & AUVs
– Swath altimetry (SWOT)
– Expendable long-duration moorings
– Gliders for boundary current monitoring
– Eddy covariance CO2 fluxes on SOFS-Pulse
– Assimilating obs into forecasting: gliders, XBT, radar
• New drivers: Antarctic 20 year plan, Marine Science
Plan and ‘blue economy’
• New collaborations: Indian Ocean Expedition
Opportunities
• Assess existing national wave buoy network
• Use available tools (CAWCR wave hindcast)
to...
• Determine gaps and recommend possible new
installations.
• Justification
– Renewable energy industry
– Erosion and inundation
– Public safety
Real time wave observations
• Assimilation of data into a 2-5km resolution model
that includes transports. Combined with...
• Model-based assessment of multi-platform
monitoring
• Could lead to a deployment plan for gliders and
moorings for EAC heat, mass, salt transport
Leaveraging the EAC array
• 66 to date:
• 28 India Bio
• 12 India O2
only
• 12 Australia
Bio
• 16 Australia O2
• Planned Bio
(2 years):
• 22 India
• 12 Australia

Indian ocean BGC floats to date
SOCCOM floats
• Prospectus
• Sensor
development
• Regional pilots
• Global design
and costing
Deep Argo: good progress
• Major game-changer on its way in 2020: Wide swath altimetry
– SWOT: Surface Water and Ocean Topography mission
– Unprecedented spatial resolution ~120 km swath width x 1km
• Sub-facility is on the SWOT science team. Mission agencies seeking
cal/val at Bass Strait. Many open questions in this space.
– Requires new approaches to measurement and cal/val
– ARC DP submitted on the topic of “buoy-swarms” for SSH determination
Altimetry: Brave new world
• Costs for some facilities (SOTS) may decrease
– May enable new projects without cutting existing
• New technologies
– Biogeochemical floats (eg SOCCOM), deep Argo
– Ice-capable floats & AUVs
– Swath altimetry (SWOT)
– Expendable long-duration moorings
– Gliders for boundary current monitoring
– Eddy covariance CO2 fluxes on SOFS-Pulse
– Assimilating obs into forecasting: gliders, XBT, radar
• New drivers: Antarctic 20 year plan, Marine Science
Plan and ‘blue economy’
• New collaborations: Indian Ocean Expedition
Opportunities
IMOX: Ming Feng and Lisa Beal
• ‘CSIRO will honour IMOS contracts’
• Argo took a 20% cut, ACE/ACCSP/US contributions
also down: Reduced regional coverage
• GOSHIP reoccupations. Next are 7-8 years away
but need a discussion and plan: Universities?
• National support for ‘public good’ science?
• Ship time on Investigator and in the Antarctic
• Reduced capability and co-investment by one
partner threatens the whole. Especially true for
facilities that are small teams.
• Need for tough prioritisation may threaten goodwill
