SUMMARY

The plot below shows the path of UpTempO 2020 #1 MIRAI 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).

TEMPERATURE TIME SERIES

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

The percent of the time that the buoy spent submerged is plotted in black, while battery voltage is shown in red.

Derived Quantities

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.
