September 15-16, 2008
Weather: Full sun all day. Light marine haze in morning, but blown out by afternoon. Winds increasing out of west to 20 – 22 knots by afternoon; waves increasing all day as well. Large swell and frequent white caps present all around FLIP during afternoon. FLIP tilted at an average of 5O. Sampling was cut short as wind was getting too strong to continue walking out on boom and sea surface was too rough to continue taking upwelling measurements. Gusts of +25 knots by 15:30 local. Some trouble with another floating instrument coming into the field of view of DPOL throughout sampling and in some cases their cables became tangled.
Instrumentation used: Sky camera system was run from 15:45 GMT – 16:45 GMT and 20:15 GMT – 22:30 GMT. Images were taken in cycles that took 1 image with each appropriate spectral filter and polarizer combination. A typical cycle took about 6 minutes to complete and cycles were started every 15 minutes.
DPOL instrument was run from 19:30 GMT – 22:30 GMT sampling upwelling light. This was accomplished by floating the instrument down current from the ship on the surface of the water. Images from this instrument were taken in cycles that consisted of 1 image with each spectral filter and then that sequence was looped 5 times. Cycles took about 12 minutes to complete and cycles were started every 15 minutes corresponding with the sky camera cycles.
Microtops sunphotometers were also taken generally every 15 minutes corresponding to the previous 2 instruments’ sampling schedule. The microtops were taken from 16:00 GMT – 22:30 GMT.
