Science driven experiments to enables technical development

For those using or discussing

gliders

27 publications since 2005

Transition in last 3 years from

technical engineering

manuscripts to science results

The COOL group provides a rich engineering/science

environmental test-bed that allows for technology

development locally before being transplanted globally

The Ocean Observatory Initiative (OOI) will develop an interactive

laboratory integrated by a leading-edge, multi-scalar

cyberinfrastructure

Currently in construction phase

with 5 implementing organizations

leading large consortia of academic

partners

Coastal Global Networks: WHOI & OSU (PI)

Regional Cable Network: U. Washington (PI)

Cyberinfrastructure: Scripps (PI)

Education & Public Engagement: Rutgers (PI)


7/27

Participating Institutions: Rutgers, MIT,

Scripps, Wood Hole, NRL, U Mass, U

Maryland, JPL, WHOI, Cal Poly, U Del,Stevens, OSU, USGS, NOAA, NURC,

NWS(~125 scientists & engineers)

To test the software, OOI used an

existing ocean network. The test

engaged scientists from across the

country who used the software to

enable their science. For OOI, the

network provided an ideal realworld test

COMBINING THE FIELD ASSETTS WITH OCEAN FORECASTS

FOR PLANNING AND PROSECUTION EFFORTS

Known constraints (slow 0.5 knot,

Battery, shipping lanes) Uncertain constraints (time-varying

3D currents)

Operate autonomously & re-plandaily

From A to B in the shortest time

Follow a time-varying feature(shelf-slope salinity intrusion)

Turbulence levels increase rapidly with

currents, drop slowly.

Density stratification mixes away rapidly

at Southern Glider little influence throughstorm

Maximum resuspension occurs late in the

storm

Alongshore Transport is

downshelf with storm

Cross-shore Transport is (a)

onshore for both gliders during

peak, and (b) offshore for the

northern glider after the storm.

Northern glider is consistent with

expected downwelling during

northeaster

Depth Integrated Results: Northern Glider RU21; Southern Glider RU05
