These data were sent to Dennis et al for use in their fcast runs when they come back out Friday. The results are extremely encouraging. I had mentioned in a message earlier today that drifters released along the 60m isobath by Jim on 12 May (4am EDT) had taken an initial (weak but) eastward trajectory, whereas the drifters released along the 45m isobath had taken a more typical southwestward transit. The results assimilating the Edwin Link ADCP data (sent out in an earlier message) captured this difference in drift patterns (slightly eastward in the 60 m drifters and southwestward in the 45m drifters). If the Link ADCP data is not included, the southwestward flow is much more pronounced. This result is visually striking in a run simulating all drifter trajectories, i.e., the Endeavor drifters and the Link drifters. I suggest that the Endeavor team lauch a run to confirm these results - simulating releasing their drifters (or a cloud of drifters straddling the above isobaths) and keeping the numerical drifters in the water throughout the run - say through 15 May. I am still sifting through output and hope to have more quantitative measures to report. Note: I have NOT assimilated any of the drifter m3d files (neither the Endeavor's or the Link's). I have used only the Endeavor's ADCP from svy1, 2 and 3 and the the Link's el9905a1.m3d (the one without the 1 hour filter). I attach below the DRIFTERS.ind file with the 8 drifters in question. I'll stop here so that this message makes the midnight ship's e-mail. Cheers, Cisco. > <> ------_=_NextPart_000_01BE9D97.4AECD1A0 Content-Type: application/octet-stream; name="DRIFTERS.ind" Content-Disposition: attachment; filename="DRIFTERS.ind" {Comment:} SFlank, EN323 (7, 37, 22, 9) and EL9905 (200, 395, 234, 393) Drifters {# of model dt"s btwn particle position updates} 1 {# of drog updates btwn drogue outputs} 1 {grid scaling factors in x,y directions} 1.0 1.0 1.0 {drog coordinate scaling factors} 1.0 1.0 1.0 {Number of starting drogues (ndr)} 8 {Starting Positions of Drogues} 286643.270 -126111.439 -1 1999 126.526 290503.509 -134076.204 -25 1999 126.563 292228.296 -141051.723 -25 1999 126.608 290010.712 -141269.599 -1 1999 126.674 2.88836214e+05 -1.3265847e+05 -33 1999 131.2646 2.89107252e+05 -1.3229854e+05 -13 1999 131.2708 2.96770237e+05 -1.4374202e+05 -33 1999 131.3368 2.96770237e+05 -1.4374202e+05 -8 1999 131.3368 ------_=_NextPart_000_01BE9D97.4AECD1A0--
