Deployed at Ice Station Barneo in April 2013, the two web cameras are about 200 to 300-m apart with
WebCam#2 looking to the right side of WebCam#1 and WebCam#1 looking away from WebCam#2.
Image times are not synchronized between the two WebCam buoys.

Web Camera #1 is a system built and deployed by the Polar Science Center in April 2013 at the Barneo ice camp approximately 25 miles from the North Pole as part of the NSF-funded North Pole Environmental Observatory (NPEO). It is meant to give a visual record of ice changes over the spring-summer-fall season. Ablation stakes made of plywood strips 10-cm wide and marked with alternating black and white 10-cm squares are planted in the ice near the buoy to indicate visually the amount of surface melting as the summer proceeds. Also in the field of view of this camera are an Ice-T buoy built by Frederic Vivier of Le Laboratoire Ocean Université Pierre et Marie Curie (UPMC) to measure bottom melt and heat conduction through the ice and a Polar Ocean Profiling System (POPS) installed by Takashi Kikuchi of JAMSTEC to measure temperature and salinity profiles in the top 1000 m of the ocean. The camera is about 1.5 m above the April ice surface. The Ice-T buoy is 12-14 m away from the camera and the POPs buoy is about 53 m away.
Web Camera #2 was built by the Polar Science Center with the support of Jean-Claude Gascard of UPMC. It was installed and its data are recovered by NPEO in a joint effort with UPMC. It was installed in part to monitor the fate of the large Acoustic Ice Tethered Profiler (AITP) ocean buoy its AITPs laser cloud sensor. For this reason it was placed close to (~ 3 meters) the AITP. It is also surrounded with 10-cm wide ablation stakes. The camera stands about 1.8 m above the April level of the ice surface. Owing to the wide-angle lenses used in the cameras, the AITP and the stakes are closer to the camera than they appear. The two web cameras are about 200 to 300-m apart with Web Camera #2 looking to the right side of Web Camera #1 and Web Camera #1 looking away from Web Camera #2.
