Narrative:
----------

HOT-20 departed Snug Harbor aboard the R/V Moana Wave at 0800 on 13
September 1990. Kahe Point was visited en route to Station ALOHA, and
XBTs were dropped after leaving the Kahe Point Station.

Upon arrival at Station ALOHA the time-series sediment trap array was
deployed. In addition, an experimental sediment trap array was deployed
for scientists at the University of Southern Mississipi.

The hydrowire parted on the first cast at Station ALOHA and the CTD was
lost. The science party returned to Snug Harbor immediately to collect
grappling gear with which to recover the array. After returning to
Station ALOHA, both the time-series' and USM traps were recovered.

The CTD was eventually recovered using grappling gear and HOT-20
returned to Snug Harbor at approximately 2200 on 17 September. Other
than the sediment trap data and the downcast data from WOCE deep cast,
no data were collected at Station ALOHA on HOT-20.
