3.0 WHAT NOAA/NOS COULD DO IN THE NEAR-TERM 



NOS is presently performing two projects to improve measurements in the 

 Arctic region. The first is the establishment of a year-round tide station on the 

 north slope of Alaska. The second is the testing and evaluation of a new type 

 bench mark resistant to frost heave. 



3.1 Prudhoe Bay Saltwater Treatment Plant 



The establishment of a long-term, year-round, tide station, using NGWLMS 

 technology, at the ARCO Saltwater Treatment Plant (STP) in Prudhoe Bay was 

 accomplished in July 1990. This station will replace the seasonal Prudhoe Bay 

 station located about 1 .6 Km away on the same gravel causeway known as West 

 Dock. A year-round station at the STP is possible only through the unique 

 circumstances associated with the STP design. The ARCO STP is a massive 

 barge sunk in-place at the end of West Dock. It is surrounded on three sides by 

 gravel, with the fourth side fronting onto a small, sheltered, bay. The STP is used 

 to process seawater before it is pumped underground to facilitate oil removal. 

 Two bubbler gages were installed at the STP in August of 1988. The instruments
