Less than 1 percent of U.S. Arctic waters have been surveyed to modern standards. In fact, some nautical charts date back to Captain COOK's time. Here's what it takes to bring those maps into the modern age.

We have had a lot of marine accidents that involved failure of the hull structures. Whether it was a crack in the midship region, or a total split-off of the hull girder, or failures due to propagation of cracks, the crux of the matter boils down to a handful of causes that are of great concern to ship designers and operators. Mostly, crack propagation takes place due to fatigue, which is not something this article is about. This article gives an insight into the causes that lead to the failure of the hull girder from a longitudinal strength point of view. And before we start, we have to ask ourselves a few questions. Why have ships split-off? Why have many hull structures split-off after grounding? Why are midships highly prone to such failures? Is it because of a design flaw? Or for that matter, a glitch in the operation standards that have not been maintained?

Recent reports that some would-be rescuers do not fully understand the legal context of rescue at sea, and may have been deterred from helping people in distress because of possible legal action by local authorities seeking to counter trafficking activity are misplaced, according to the International Maritime Rescue Federation (IMRF).
