From: Ocean depth–temperature profiles for operational oceanography from a shark-borne transmitter
Illustrates comparisons of uplinked profiles with profiles extracted from the nearest model grid point from an operational model, in this case the Regional Ocean Modeling System (ROMS) run daily by the Pacific Islands Ocean Observing System (PacIOOS). Preliminary comparisons of all transmitter-derived data to a regional model show these data to agree at first order (Fig. 4) indicating that they have the potential to further constrain (via assimilation) or validate the model in these regions. Comparison of two representative shark tag profiles with ROMs profiles for the same location. Profile 11 (top) created over a period of 4.5 h originated at 464 m and was linked with a Fastloc GPS location (21.1152 N; –157.7643 W) obtained within 3 min of its creation and derived from 6 GPS satellites which yields a median location accuracy of 30 m [3]. This profile contained no ‘discontinuities’. Profile 275 (bottom) was generated over a period of 5 h and linked to an Argos ‘quality 0’ location estimate obtained 15 min after profile generation. Uplink latency was 2.5 h
