Customs
When visiting research bases or stations, tourists are asked to remove shoes, never to enter a building unless invited, not to interfere with scientific work, and to remember that researchers are using up precious work time to accommodate them. Make sure that restroom facilities aboard ship are used before visiting a base, as it is very bad practice to ask to use one on shore and it adds to the amount of waste that has to be removed by the researchers at a later date.
ElectricityEach ship and base has its own electricity supply. Russian ships will have a 220-volt, 50Hz supply with a round two-pin plug connection.
