Interactive Drifter Trajectory for Search & Rescue and Oil Spill Response

IOOS Products Workshop, May 17-19

Why do we need an interactive drifter trajectory (IDT) tool?

  • Marine search-and-rescue (SAR) operations

– Accurate information is critical during the early hours of response

  • Forecast errors & search area grow rapidly with time
  • Extreme conditions increase the risk to human life dramatically
  • Oil spill response
  • Needs for user-friendly interface and easy data access

– Interactive interface with no humans in the loop – Data interoperability with USCG/ASA and NOAA/GNOME environmental data servers

Interactive Drifter Trajectory (IDT) developed by JPL/UCLA

  • Funded by NASA as a 3-year (2009-2011) project in

collaboration with USCG, ASA, and AOOS

  • First IOOS funding by CeNCOOS -Steve Ramp

– Drifter releases one at a time or in cluster

  • Further development funded by AOOS -Molly

McCammon and Carl Schoch – Drifter releases use ensemble ROMS forecasts – Field tested in Prince William Sound 2009

  • Used real-time by SCCOOS

Specify the drifter depth (surface vs 10-m, etc)

slide-9

9 IOOS Products Workshop, May 17-19

Specify the start and end time (day/hour)

slide-10
SLIDE 10

10 IOOS Products Workshop, May 17-19

Click Compute & Plot:

You have submitted a new request, asking the hourly ROMS forecast surface current to produce drifter trajectories over the specified period

slide-11
SLIDE 11

11 IOOS Products Workshop, May 17-19

It should only take a few seconds

If it takes more than a minute, you should email or call Yi Chao

Drifter will stop once hitting land.

Multiple Drop Mode: M by N configuration 20 drifters = 4 x 5

slide-14
SLIDE 14

14 IOOS Products Workshop, May 17-19

It takes a little longer, please be patient

But if more than a minute, email or call Yi Chao Drifter will stop once hitting land.

Interactive Drifter Trajectory (IDT): 16-member Ensemble ROMS forecast

(with more computing power, we can do more than 16 members if needed)

slide-16

16 IOOS Products Workshop, May 17-19

Click to release or type in the location in long/lat

slide-17
SLIDE 17

17 IOOS Products Workshop, May 17-19

Click Compute & Plot:

You have submitted a new request, asking the16-member ensemble hourly ROMS forecast surface current to produce drifter trajectories over the specified period; each ensemble member differs slightly in its initial condition with everything else exactly the same

slide-18
SLIDE 18

18 IOOS Products Workshop, May 17-19

The ensemble takes longer, ~2 min for 2-week drifting period)

(Reducing the drifting period takes less time)

Drifter will stop once hitting land.

Future Work

  • Near-term objectives

– Apply the developed drifter trajectory tool with HF radar gridded (gap-free) current – Provide drifter trajectory tool and service to other interested RAs

  • Long-term goal

– Develop a national IOOS-wide drifter trajectory tool
