3-D Oceanography Notes

(John Dower Facilitator, Mairi Best Rapportrice)

At what scale are observations needed, depends on scale of phenomena?

What do we want to measure?

-bedforms and change over time

-event response

-fine scale mapping at Ridge

-movement of water masses

-biological response to physical and chemical changes in ocean

-thermal characteristics of ocean

-ocean acidification

-turbidity

-currents (ADCP's, ACM's)

-Canyon dynamics – integration with benthic and sediment group

-nutrients

-tracer tracking

Barkley Sound

-data bridges through shipboard sampling

-integrated with Bamfield education systems

-coordinate with local people, engaged with observing

Infrastructure/Platforms:

Gliders, AUV's

benefit for monitoring and research programs

integration into existing cruise programs

start by ship based use of gliders and AUV's then integrate into docking stations

Gliders

-being acquired through VENUS CFI (Webb)

-what payload would we want on a glider

-route between Folger and Barkley Canyon

-intercalibration with NC fixed assets

->John D., Jody Klymak,

AUV's:

-need to move to docking stations, for power and data

-expensive, need to develop docking stations

-WHOI AUV

-PMEL team

-OTTB

->target people who are already using the technology, and bring them in to the NC fold

->docking technology

Vertical profilers

-four initially proposed, 2 on upper slope, two down slope

-Folger

-can also look at fixed moorings

Tomography:

-ocean accoustic tomography

-Bruce Howe

-ocean waves and temperature

-hydrophones and a sound source

-timing

-issue of sound source, can use coded source

-Test response of whales to active sources

-Use natural noise of ocean as noise source, e.g.earthquakes?

CODAR

-radar

-scattering off surface waves, ship traffic, search and rescue, military, surfers

-VENUS already acquiring

-Rutgers

-Bamfield

-30-100km

-100k

-surface wave map

-air-sea interface exchange e.g. Gases

-Diane Masson

-OEA

-cross calibration with wave sensor at Folger Shallow, and buoy Uculet

-relationship with BPR data, seabed processes

Buoys

-co-located with NC system, autonomous or plugged into NC system

-L-boxes

-operated or data integrated into by existing buoy system, interoperability with NC

-accoustic modem connection to mooring

Data Visualization, Analysis, and Modelling
-bring in other groups: climate modellers, weather models, Rutgers, Pacific Institute of Climate Studies

-users develop products and share with community

-data analysis boot camps

Interoperability
-Satellite solutions focused on our node areas

-buoy solutions focused on our node areas

-assessment of utility of current instrumentation in DFO monitoring programs, assessment of what would be key developments to make this more useful for them.
