This eps figure (meso2_wec_nh_diff.eps) is a plot of the distance between the New Horizon and the Wecoma during the July-Aug 2000 cruise. It plots positions at identical times only. The plot indicates that the ships were generally within ca. 70 km of each other throughout the cruise period, and there were 11 specific times when the ships were within ca. 20 km of each other. The eps figure can be retrieved by clicking here.

This eps figure (meso2_wec_nh_diff0.2.eps) is a 2-panel plot of the minimum distance between the New Horizon and the Wecoma during the July-Aug 2000 cruise. The top panel is a plot of the minimum distance between the two vessels. The time refers to the time on the New Horizon. The minimum distance was determined by windowing the Wecoma positions within +/- 0.2 days of the New Horizon time; the minimum intervessel distance from that time window is then plotted. The bottom panel is the time offset for the Wecoma which provides the minimum distance between the two vessels for a given New Horizon time (x-axis). Positive times are Wecoma times preceeding NH times; negative times are reverse.

The table below provides links to jpg and eps plots the New Horizon ship track in Black, Wecoma ship track in white, and Sea Eagle Stations in Magenta. The Sea Eagle was not equipped with an underway sensor, so only station positions are available. There are separate plots for each half-day time interval, with time as GMT. Or if you prefer an FLC animation loop, with similar plots (only at 0.2 day intervals) is available by downloading and saving this file (meso2.flc). Information and software for playing FLC animations is available at http://crusty.er.usgs.gov/flc.html.
