Abstract : As of August 1995, the entire Indian Ocean surface drifter array is in place. Delays in the initial deployments somewhat compromised the original plan to have the entire array in place prior to WHP work. The delays resulted in a problem with the PTT's from Telonics that cropped up in the NOAA funded southern ocean drifters. To be safe, the Indian Ocean drifters were held in storage while the problem was solved. A test of all of the units in Miami showed that they were all operational even though they were from a similar batch as those with clock problems in the southern ocean units. In the end, there were no drifter losses tied to the problem, but the timing of the array was shifted by approximately six months. The southern Indian gyre, the least known portion of the Indian Ocean circulation, was well seeded in the time frame of WHP. The lag was mostly felt in the northern Arabian Sea where deployment became tied to research vessels schedules and shipping issues. The array as of fall 1995 is shown in the enclosed figure. Redeployment resources are on line although uncertainties in NOAA funding may make future deployments a problem.
