Would those on the Main Deck or Well Deck have had an even better chance to spot icebergs than those on bridge or crow's nest ?The bridge naturally has a better chance of spotting objects, at night, than the crows nest, because Murdoch was looking straight at a black silhouette and the lookouts were looking down at the berg, making it more difficult to make out distinct shapes and sizes.
Yes it was. Here is a plot I made recently of all the ice bergs reported in the vicinity. It is not exactly to scale but the position of the icebergs can clearly be seen. The north-south barrier of the pack ice is shown in dark green and the track of the Carpathia is shown as a dotted black line. It is not shown straight since she would have been set east by the Atlantic Current. There is no sign of any bergs within the horizon of people in lifeboats. However, a 100 foot berg would be seen at a maximum distance of about 15 miles by someone in a lifeboat and much farther from the deck of Carpathia. THE iceberg is shown as a black triangle. Have fun!So was THE iceberg the only one in the vicinity? (Near the lifeboats and the Carpathia)
