Fig. 8From: The value of using measurements of geomagnetic field in addition to irradiance and sea surface temperature to estimate geolocations of tagged aquatic animalsPath taken by the PTT as it drifted across the North Atlantic Ocean with the geomagnetic-irradiance-SST-derived positions indicated by solid green diamonds and the Doppler-derived positions by solid white triangles. Note that the track based on the use of three inputs and processed through a state-space model is closer to the ARGOS-determined track than the two tracks shown in Fig. 2 Back to article page
