UpTempO 2011 #5 Araon - Deceased
Made by MetOcean Data Systems
Iridium ID # (IMEI = International Mobile Equipment Identity): 300234010956630
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 Phil Hwang (Scottish Association for Marine Science) and colleagues from the Korean Polar Research Institute in an ice floe during the Arctic Ocean cruise of the Korean icebreaker Araon.
Initial status: Within 2 days, most ocean thermistors began to give unrealistic values. Position and atmospheric/oceanic pressure data were unaffected.

THANKS TO: Phil Hwang (SAMS) and KOPRI colleagues for their work in getting this buoy onto the ship and then onto the ice.
SUMMARY
The plot below shows the path of UpTempO 2011 #5 Araon 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).

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.
