Cruise Report OC454-2


================Underway Data and ATHENA
The Underway  data collection system worked well for the  entire cruise.



================Currents2 NB150 and NB75
Both ADCPs, the 150 and 75  worked well for the cruise as did the Ashtec.

For information on processing the ADCP data contact Frank Bahr 
at fbahr@whoi.edu or Jules Hummon at  hummon@hawaii.edu.


=================CTD 

We did 11 CTD casts and touched bottom on two, CTD9 and CTD10. The sensors
were flushed and appeared to be working. 

On several of the CTD casts, data collection was stopped on the way up. 

The processing performed at sea was for a 'quick' look to see how the sensors
were behaving.

The CTD was configured as follows:

OC454-2: SBE 911+ Config
Sensor 	Frequency 	s/n 	Calibration
temperature, 	0 	4303, 	2008-09-25
conductivity, 	1 	2707, 	2008-09-24,
pressure, 	2 	69685, 	12/18/2002 		
temperature, 	3 	4312, 	2008-09-23
conductivity, 	4 	2768, 	2008-09-25,
The external voltage channels are:
# Extrnl Volt 0 WET Labs, ECO_AFL
# Extrnl Volt 1 userpoly 0, FLNTURTD-1013, 2008-04-18
# Extrnl Volt 2 transmissometer, primary, CST-1117DR, 2008-04-30
# Extrnl Volt 4 altimeter
# Extrnl Volt 5 Oxygen, SBE, primary, 0794, 2009-03-13
# Extrnl Volt 6 userpoly 1, Flashbird-5
# Extrnl Volt 7 Oxygen, SBE, secondary, 0072, 2009-05-13
# Extrnl Volt 9 surface irradiance (SPAR), degrees 


================Knudsen
We logged knudsen 320BR .kea and .keb files. The EPC GSP-1086 did not 
work and is being sent back to the factory.

Sound velocity was changed in the knudsen Echo Control
software from 1505 to 1545. This increased the depth by 
approximately 90 meters.

Data collected from start of cruise to before July 31 0829
was collected w/ a sound velocity of 1505.

Data collectd from July 31, 0829 gmt on  used 1543.

The first data files w/ 1543 for sound velocity are:
212_0829*


================Camera
Dan's camera was on the rosette. It did not work on CTD2, and
on closer inspection the control Jbox had been compromised. 
Currently, we are unsure what caused it to leak under pressure.
