Thanks to Quest’s regularity, continuing gaps in the location data from her transmitter haven’t hindered our ability to follow her movements. As you’ll see from the latest map she continues her stay in the Tom Nevers neighborhood. In an unusual coincidence, Quest’s trip up the beach on 22 January found her in exactly the same location as she was on the 1st of January, right down to 1/1000th of a degree! The time stamps for the location data are different for each day, so this might indicate that she has a favored spot at that location.
Perhaps the most interesting data from the past week concerned the temperature. Quest’s satellite transmitter has a small temperature sensor built into it. This sensor measures the temperature of the transmitter unit, which is influenced by the temperature of Quest’s environment, and also her own body temperature. Provided that the signal strength is good, we usually receive a temperature reading along with each location. Often, the temperature readings aren’t much different than the ambient temperature at her location. This most likely means that Quest is in a relatively exposed location.
The interesting bit is that for the past week, while average daily temperatures in Nantucket have hovered between -1° and -4°C, Quest’s temperature sensor has been reading 20 to 25 degrees higher than that. In fact, the temperature reading on 26 January was 32.39°C, or 90.3°F. That’s a pretty high temperature for the middle of winter, and it may indicate that Quest is finding good shelter from the elements. It’s yet another positive sign that her survival instincts are developing well.
