The furor over the proposed sale of a London-based firm that operates facilities at some U.S. ports to a company in the United Arab Emirates has focused Congress’s attention on the issue of maritime security. The U.S. part of this deal appears to be dead, but real dangers remain—specifically, that Congress will implement policies that will not make Americans safer and could actually harm U.S. interests. There are at least four bad proposals on the table that Congress should reject. (Continue)
The American Practical Navigator (Pub 9) is a publication which describes the modern principles of marine navigation and includes the formulas, tables, data and instructions required by navigators to perform the computations associated with dead reckoning, piloting, and celestial navigation. The publication also contains sections addressing the Practice of Navigation, Navigational Safety, Oceanography, Weather, and Electronic Navigation. It is prepared and published by NGA on a five-year program. This publication is available in its entirety on the website. A Marine Navigation Calculator function is also available on the website which performs many of the navigational computations derived from formulas and data found within this publication's text and tables.
green flash. . A brilliant green coloring of the upper edge of the sun as it appears at sunrise or disappears at sunset when there is a clear, distinct horizon. It is due to refraction by the atmosphere, which disperses the first (or last) spot of light into a spectrum and causes the colors to appear (or disappear) in the order of refrangibility. The green is bent more than red or yellow and hence is visible sooner at sunrise and later at sunset.
Bridge watches (at least those I was a part of) would look at sunset to see if there is going to be a green flash. I have to say that it is pretty cool to see the upper edge of the sun turn green right before disappearing below the horizon. It is also possible that there is a green flash in the morning but it is a little more challenging to see it as you can't see the sun beforehand to get an idea when/where to look.
