Nimrod Expedition
During Rear-Admiral A Mostyn Field's term as Hydrographer to the Admiralty Board, the Hydrographic Office lent instruments to the Nimrod Expedition of the British Antarctic Expedition led by Ernest Shackleton in 1907. Following the RMS "Titanic" in 1912, the Safety of Life at Sea (SOLAS) convention was established, as well as the introduction of ice reporting and forecasting. During World War I, while Rear-Admiral Sir John F Parry was Hydrographer of the Navy, the Hydrographic Office produced numerous new charts and products to support the Royal Navy.
