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

Here is the list of field names:

Field name Description Units
Year The year the data were collected n/a
Yday Decimal year day UTC, January 1 at 00:00 is 1.0
MO The month the data was collected UTC
DA The day the data were collected UTC
HH The hour the data were collected UTC
MM The minute the data were collected UTC
SS The second the data were collected UTC

NOTE: data available for fall 2004 upon request


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


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


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

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??

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

NOTE: florometer (#417) deployed with density array


Deployed 10/08 - 2/09

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


Deployed 7/09 - 6/09/2010

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


ucat02 fouled 1/3/2010


Deployed 6/09/10 (yd 160) - 2/8/12 (yd 39)

NOTE: florometer (SN 962) deployed with density array near 8m ucat

NOTE: ucat02 (topmost CTD) flushed on 9/16/2010


Deployed 2/08/12 (yd 39) - 11/13

NOTE: florometer - SN 692 (orange) deployed with density array 8mdepth-0.45m
