A Met One anemometer was mounted on the top of the pipe at position 35. 
The anemometer was hit by high waves and failed on October 13. 
DELILAH array gauge numbering 
The following tables list the DELILAH instruments by gauge number and 
name. The gauge number is a four-digit number uniquely identifying the 
gauge, while the gauge name is a short alphanumeric string that identifies both 
the type of instrument and the location. Both were required to collect and 
process data at the FRF. 
Included in both labels is the location numbering scheme (Figure E1) 
which uses a two digit-number to locate every surf zone instrument. The first 
digit (1-9) refers to the cross-shore locations starting at the shoreline and 
moving offshore. The second digit numbers the longshore location starting 
with O at the primary cross-shore array and increasing to 5 at the southernmost 
gauge location. 
The gauge number is stored in the header of the FRF's time series data 
(along with other information such as the gauge depth, gain, and bias). It is 
composed of four digits. The first digit, always a 2, identifies the gauge as a
