Notes:
All floats were ballasted for the 27.5 st surface. They were all programmed for 540 days
except for float 575, which was programmed for 180 days. All missions were started
on 7/19/98, with the first listening window on 7/20 [except for 575 started on 7/24,
566 on 7/22], so surfaced on 1/11/2000 [566 on 1/14/2000]; 575 surfaced as scheduled
on 1/21/99.
(a) Float 567 was at/near the surface days 137-290, 307-325, 489-540 (end). Otherwise
it was generally less than 100 meters below the surface, often less than 50 meters.
This consequently led to difficulties in tracking.
(b) Float 572 was at/near the surface days 190-273, and picked up by fishermen
approximately day 478; "surface" position is the location it was picked up.
(c) Float 552 was on the surface after day 400, and picked up by fishermen
approximately one month later; "surface" position is the location it was picked up.
