All times UTC

21Jun07 start cruise
---------------------------------------------------------------------------------------

ADCP75 not outputting or saving data 2222z 28Jun07 until 1603z 29Jun07

Knudsen Echosounder 12KHz not outputting good data from 0805z 30Jun07 until 0856z 30Jun07

Bottom depth: Knudsen value = ADCP value + ~6m
Knudsen Echosounder barcheck sound velocity = 1495. Sound velocity Value changes w/ depth and inshore/offshore location.
range of depths from ~7m at dock to ~800m max.

---------------------------------------------------------------------------------------
NavTrac	mostly 2, often to 1, very rarely/never to 0.
NStar	mostly 2, sometimes to 1 (less often than NavTrac), rarely to 0.
PCode	mostly 3, rarely to 1 and 0, more often to 0 than 1.
Furuno	mostly 2 rarely to 1 (427for first part of each day), never to 0

Heading value example values:
Gyro1	23.500
Gyro2	25.600
ADU2	24.837

Speeds ~0-13kts
SMG:
NStar most focused, ADCP(SpdFwdBtm) averaged, thus less spiky, slightly lower than NStar values by ~0.5kts. NavTrac values larger than ADCP by ~0.75kts & larger than NStar by ~0.25kts. NavTrac spiky like EDO(SpdFwdWtr)

NavTrac	10.970	average is higher than NStar by ~.25 kt
NStar	11.100	Most focused
EDO	11.060	Most wild values, real possibly. Compare on station vs steaming.
ADCP75	11.000	averaged value, thus less spiky. less than NStar by ~.5 kt
As usual, Air Temp is affected by heading & wind direction due to heat from stack.
