[ESIP-all] Looking for recent earth observations of the Tasman Sea

I've heard that satellite radar images are useful for boat detection in the open ocean.   A special acquisition from one of the international radar satellites could be requested.  The Alaska Synthetic Apperature Radar (SAR) Facility (ASF) is the NASA data center that deals with this type of data.  See:  http://www.asf.alaska.edu/program/sdc

DigitalGlobe (www.digitalglobe.com) has the GeoEye-1 satellite. The satellite provides 41 cm panchromatic and 1.65 meter multispectral imagery in 15.2 km swaths. The spacecraft in a sun-synchronous orbit at an altitude of 680 km (422 mi) with a 10:30a equator crossing time. I don't know anyone at DigitalGlobe but you can google/bing them to find a contact.  

NASA does not have any high resolution satellite imagery that could spot a boat.
