README_moor_adcp.txt

Overview:


 This data set provides measurements collected during the Lagrangian Transport and Transformation Experiment (LATTE) April 2005. Data were collected from moored instruments platforms deployed on the continental shelf off the coast of New Jersey.  Data was collected at 5 moorings designated N1,C1,C2,C and S1. Mooring details are inlcuded in the Mooring report. 


Data files are partitioned in the following way:

There is one set of files for each ADCP.

Moorings C1,c2,c3 and S1 had RDI ADCP's deployed for current messurement. Mooring C2 was underpowered to reach the surface for much of the deployment. 

A sontek ADP was deployed at N1.

Data format C1,C2,C3,S1: 

There are two file formats provided, Matlab (*.mat) and ASCII format.

-----------------------------------------------------------------------------
Variables included in Matlab data files are:
-----------------------------------------------------------------------------

Name	Description        
  

u	Water Velocity E-W (m/s)
v	Water Velocity N-S (m/s)
w	Water Velocity Vertical(m/s)
b	Acoustic Backscatter (db)
time	Matlab datenum time
bins 	bin distance(m)
depth	Depth calculated from Acoustic backscatter(m)
press	Pressure from ADCP mounted pressure sensor(m). (if available, otherwise this variable is filled with a constant) 

-----------------------------------------------------------------------------
ASCII files are formatted.
-----------------------------------------------------------------------------

The first line contains the distances from the adcp to the center of each bin.


Then each ensemble has:

Time	Depth(m) Pressure(m)

U Velocity(m/s)	  V Velocity(m/s)  Vertical velocity(m/s)  Backscatter(db)



Data format n1: 

There are two file formats provided, Matlab (*.mat) and ASCII format.

-----------------------------------------------------------------------------
Variables included in Matlab data files are:
-----------------------------------------------------------------------------

Name	Description        
  

u	Water Velocity E-W (m/s)
v	Water Velocity N-S (m/s)
w	Water Velocity Vertical(m/s)
b	Acoustic Backscatter (db)
time	Matlab datenum time
bins 	Bin distance(m)
press	Pressure from ADP mounted pressure sensor(m).
sal	Salinity(PSU)
temp	Temperature(V)
obs	Optical backscatter(volts)

-----------------------------------------------------------------------------
ASCII files are formatted.
-----------------------------------------------------------------------------

The first line contains the distances from the adcp to the center of each bin.


Then each ensemble has:

Time	Pressure(m) Salinity(PSU) Temperature(C) OBS(V)

U Velocity(m/s)	  V Velocity(m/s)  Vertical velocity(m/s)  Backscatter(db)
