Deep Arctic Ocean Canada Basin Mooring Data

Temperature, salinity, velocity and pressure data from one location in the deep Canada Basin. The instrument was a McLane Moored Profiler. Data were collected as an extension of the Beaufort Gyre Observing System (BGOS, whoi.edu/beaufortgyre/) on mooring A. These and shallower measurements on the same mooring are available also at the BGOS website.

The MMP profiled between about 2100 m and 3040 m for 25 days (61 profiles) after which time a mechanical failure prevented it from profiling and the remainder of the year-long time series has only measurements between 2144 and 2148 m. Variables contained in the Matlab file are: DPDT: array of profiling speeds cm/s S: array of salinity pss SIGTH: array of sigma-theta kg/m3 T: array of temperature deg C THETA: array of potential temperature TIME: array of time of each measurement (encoded with datenum.m) U: array of east velocity cm/s V: array of north velocity cm/s W: array of measured vertical velocity (includes profiling velocity) cm/s dates: vector string with profiler start date day: vector of decimal year day (2007) location: string with location of mooring name: string with dataset name number: vector of profile number pgrid: vector of pressure grid m.
