README FILE FOR LOMONOSOV DATA 6th June 2001 ================================================================ This is an archive of data from 3 moorings (LM1, LM2, LM3) deployed at the junction of the Lomonosov Ridge and the Eurasian continent between summer 1995 and summer 1996. LM1 78deg 30.8min N 133deg 57.7min E LM2 81deg 4.5min N 138deg 54.0min E LM3 80deg 19.2min N 150deg 3.5min E Each mooring is deployed in c.1700m of water, with instruments at depths of c. 100m, 300m, 700m, 1100m, 1700m. Header information for each record is given in each file. --------------------------------------------------------------- For full details, please see: Woodgate, R.A., Aagaard, K., Muench, R.D., Gunn, J., Bjork, G., Rudels, B., Roach, A.T., Schauer, U., 2001, The Arctic Ocean Boundary Current along the Eurasian slope and the adjacent Lomonosov Ridge: Water mass properties, transports and transformations from moored instruments.
