Density at ASIT summary data

Most of the data parameters include valus for the mean and median value as well as the standard deviation of the variable. The table below shows the field name suffix used to differentiate amoung the different values:

Field name Description

_mean The mean value of the variable over the averaging period

_m50 The median value of the variable over the averaging period

_std The standard deviation of the variable over the averaging period

_length The number of valid data points collected over the averaging period

Field name	Description
_mean	The mean value of the variable over the averaging period
_m50	The median value of the variable over the averaging period
_std	The standard deviation of the variable over the averaging period
_length	The number of valid data points collected over the averaging period

NOTE: data available for fall 2004 upon request

6/8/05 - Installed density array off end of platform; internal pumps installed;

ucat1@2m - SN3749
ucat2@8m - SN3750
ucat3@14m - SN3332 (with depth)

7/21/05 - reinstalled density array off end of platform; internal pumps installed

ucat1@2m - SN3750
ucat2@8m - SN3332 (with depth)
ucat3@14m - SN3749

10/24/06 - 7/26/07 11/05 - reinstalled density array off end of platform; internal pumps installed

NOT(discvrd 3/07)ucat1@2m - SN4222
ucat2@8m - SN4476 (with depth)
ucat3@14m - SN4223

ucat1@2m - SN3750
ucat2@8m - SN3222 (with depth)
ucat3@14m - SN4223

NOTE: 11/19/06 - deployed in different ports ...data logged incorrectly ... fixed logger to correct on 12/9/05 ...
did I rename & reprocess 11/19/06 - 12/9?/06

NOTE: transmissometer deployed with density array (TRAN2)

NOTE: on 4/16/07 array connector to helical anchor failed .. about 4:04 AM from pressure record on ucat_08 ... this means that the density string wasn't securely fastened to the seabed and could? be pushed around some?? NOTE: SN3750 pump was found to be broken after recovery -- seized up from sand in the impellor

Deployed 8/13/07 but ucats at 8 m and 14 m had troubles with comms and then died immediately
Turned off last working microcat 11/16/07 - garbage in data -- bad cable??

ucat1@2m - SN3749
ucat2@8m - SN2295 (with depth)
ucat3@14m - SN3544

NOTE: florometer deployed with density array

NOTE: suspect that sensors were mounted with 1 m of chain so that they were 1 m deeper? may really be at 2m while previous deployments were at 1 m

Deployed 11/07 - 10/12/08

ucat1@2m - SN3750
ucat2@8m - SN3332 (with depth)
ucat3@14m - SN4223

NOTE: florometer (#417) deployed with density array

Deployed 10/08 - 2/09

ucat1@2m - SN5960
ucat2@8m - SN4476 (with depth)
ucat3@14m - SN3749

NOTE: florometer (SN 958) deployed with density array near 8m ucat

Deployed 7/09 - 6/09/2010

ucat1@2m - SN3750
ucat2@8m - SN4476 (with depth)
ucat3@14m - SN4223

NOTE: florometer (SN 958) deployed with density array near 8m ucat
