Although Bolivia has been landlocked since the War of the Pacific in 1879, it still maintains its navy, which patrols Lake Titicaca and Bolivia's larger rivers. The Navy serves as a symbol that the country has not given up on regaining its lost access to the sea. As of 2008, the Bolivian Naval Force had approximately 5,000 personnel.What sound can be heard when approaching an iceberg?A fizz. When a piece of iceberg ice melts, it makes a fizzing sound called "Bergie Seltzer". This sound is made when the water-ice interface reaches compressed air bubbles trapped in the ice. As this happens, each bubble bursts, making a 'popping' sound. The bubbles contain air trapped in snow layers very early in the history of the ice, that eventually got buried to a given depth (up to several kilometers) and pressurized as it transformed into firn then to glacial ice.Which sea is the most saline in the world?Red Sea. The Red Sea is very saline due to high evaporation, very little precipitation, almost no river inflow and isolation from the rest of the Indian Ocean. Salinity reaches 41 ‰ in the northern part (Average for the world's seawater is ~35 ‰).What sea is that?Black Sea. The coccolithophore are calcite-shedding phytoplankton which has been part of the Black Sea ecology for millennia. In the summer it can color much of the Black Sea cyan, as is evident in this satellite image collected on July 15, 2012.
