... a scanner with a 360 • angle of view was simulated in order to eliminate directional dependencies. The map area was decomposed in a discrete raster and subsequently, the possible positioning accuracy was calculated for every cell based on the landmark geometry, visibility conditions and the a priori accu- racies ( Figure 4). The theoretically achievable positioning accu- racy indicated by colors from red (7.1 mm) to green (2.67 mm). ...

We used satellite telemetry to study postnesting migrations of 42 loggerhead sea turtles Caretta caretta from 3 Florida rookeries. Postnesting migrations ended in neritic (200 m) tended to be less direct, largely due to apparent influences of the Florida Current in the Atlantic and to looping travel paths (often along edges of mesoscale eddies of t...
