ocean pressure depths (m): 25
This is a “short” buoy with the deepest thermistor at 25 m nominal depth. It was deployed on March 22, 2011 by Keith van Thiel (Applied Physics Lab / University of Washington) by drilling a hole in an ice floe at a U.S. Navy ice camp (“APLIS” = Applied Physics Laboratory Ice Station). A seasonal ice mass balance buoy was also deployed nearby. Also, a CTD profiler was running nearby during the first few days of the buoy’s drift.
Initial status: All systems working.

THANKS TO: Keith van Thiel and his team from the Applied Physics Lab, as well as personnel from the Arctic Submarine Lab, for their great assistance in getting this buoy to the Arctic Ocean and into the ice. This was our first deployment in an ice floe.
SUMMARY
The plot below shows the path of UpTempO 2011 #1 APLIS 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.
