Load lines on side of cargo ship Featured 7 Aug 2003 Print

Load lines on side of cargo ship

Plimsoll lines on the side of a cargo ship. The original Plimsoll lines (the circle with a line through it) were introduced after the 1876 Merchant Shipping Act, largely due to the work of Samuel Plimsoll (1824-98). This shows the level of water at which the ship is fully laden. Later, the load line system (upper left) was introduced which takes account of different types of water. The abbreviations used are: TF (tropical fresh); F (fresh water); T (tropical salt water);s (salt water, summer) and W (salt water, winter). At right is a scale showing the distance to the keel of the ship in metres (here about 8.6m)

Lava flowing down cliff into the ocean Featured 7 Aug 2003 Print

Lava flowing down cliff into the ocean

Lava flow. Black lava cliff shrouded in steam caused by glowing orange lava boiling sea water as it flows into the ocean. This lava flow originated from the Kilauea volcano, which is one of the world's most active. Lava reaches volcanoes from the Earth's interior through faults in the crust, and is forced through them by the high pressure within the Earth. The black rock of the Hawaiian coastline is made from old lava flows. The continuous emissions from volcanoes such as Kilauea mean that the Hawaiian islands are still increasing in size
