ARCSS054:
Current Meter, Temperature, and Salinity Data from the Chukchi Sea

DATA SET DESCRIPTION:
Current meter, temperature and salinity data from an instrumented mooring in 
Barrow Canyon in the NE Chukchi Sea. 

PURPOSE: Monitor flow and water properties and their variations at this 
juncture between the Chukchi Sea and Arctic Ocean.

These data were collected opportunistically and not with NSF funding. 

Beginning date/time (GMT) 24-sep-1992 19:00:00
Ending date/time (GMT):   24-sep-1993 19:00:00
NUMBER OF DATA RECORDS  8761 collected hourly
Mooring Location: 71 deg 1.815' N; 159 deg 34.016W in upper Barrow Canyon
Bottom Depth: 79m
Instrument Depth: Speed and Direction: 76m RCM4
Temperature and Salinity: 58m RCM4
Based on the difference in pre and post-calibration values we estimate
that random errors in salinity are ~0.3 and in temperature of 0.1. The 
temperature sensor on the RCM4 at 76m failed due to a sticking encoder. There 
were a high number of rotor stalls, e.g., "zero" speeds on the RCM4 at 58m. 
We have combined the good data from both instruments into one data set to be 
representative of Barrow Canyon.
