Iridium ID # (IMEI = International Mobile Equipment Identity): 300034012196870
ocean temperature at nominal depths (m): 2.5, 5.0, 7.5, 10, 15, 20, 25, 30, 35, 40, 50, 60
ocean salinity at nominal depths (m): NA
ocean pressure depths (m): 20, 60
This is a “standard” buoy with the deepest thermistor at 60 m nominal depth. It was deployed on August 8, 2011 by Richard Krishfield (Woods Hole Oceanographic Institution) and Mike Dempsey (Institute of Ocean Sciences, Canada) by drilling a 1.8 meter deep hole in an ice floe during the Beaufort Gyre Exploration Project cruise on the Canadian icebreaker Louie St. Laurent. Nearby instrumentation: an Ice-Tethered Profiler (ITP 55) and a seasonal Ice Mass Balance Buoy.
Initial status: All systems working.

THANKS TO: Bill Williams and Jane Eert from the Institute of Ocean Sciences (Canada) for their great assistance with the logistics of getting our buoy onto the ship, and for making time during the cruise for deploying it, and to Mike Dempsey (IOS) and Rick Krishfield (WHOI) for their work in getting this buoy onto the ice, coordinated with the other buoys nearby.
SUMMARY
The plot below shows the path of UpTempO 2011 #4 Louis colored by month. The flag marks the buoy's last known location. Black contours show two isobaths: 28 m ("short buoy" max depth: e.g., 2011 APLIS buoy) and 60 m ("standard buoy"
max depth).

The temperature time series for each thermistor is shown below, plotted against day of the year or date.
OCEAN PRESSURE AND SEA LEVEL PRESSURE
This plot shows the ocean pressure(s) from the barometers placed at nominal depths (left axis), and sea level pressure in red (right axis).BATTERY VOLTAGE/SUBMERGENCE PERCENT

VELOCITY TIME SERIES
One to three hourly velocity is on the left axis.Distance between the buoy's start point and end point each day is shown in red on the right axis.Note that the total displacement of the buoy each day (red) is generally less than what one would calculate from the hourly velocities.
