Did the SS Niagara steam through the ice flow on April 10th 1912? Here is a news report shortly after news of Titanic's sinking became public.
Wonder if this "thick mist" was a local event or an effect created by the ice field, and was this seen by Titanic's lookouts? Surprised this occurred 4 days before the Titanic sank and yet no warning was given or attempt was made to survey the area and report to all traffic the precise location of the ice. My first thought would be to charter a number of vessels and place them on each side of the ice field to warn passing ships of their presence, similar to lightships at night. Perhaps this was already in minds of the Californian crew when they believed the rockets were coming from a vessel that was simply patrolling the area and trying to warn others about the presence of ice. Without knowing the Titanic was sinking, this idea would probably seem a rational thing to believe. Was Captain Lord aware there was no ice patrol, perhaps he believed there was.
Aaron, on the Newfoundland Grand Banks, one of the harshest maritime environments you can find, where two major ocean current meet over an ocean floor that goes from 70m to the abyss, «any» meteorological phenomenon can happen when you least expect it. From dead calm to hurricane ... from clear to dense green fog ... from cool to dead freezing, etc.
