Notice regarding image quality

Coastwatch users:
The surface temperature profiles maps are not updating right now due to a server outage at NOAA, which delivers the primary satellite data used to create these maps. NOAA is in the process of restoring the system; the estimated time of restoration is not available currently. Our apologies for any inconvenience, and we will resume normal delivery of the imagery as soon as the data sources are operational again.
