Introduction

Get ready to make a splash on June 21, as we celebrate World Hydrography Day! This international holiday was established by the International Hydrographic Organization (IHO) in 2005 to raise awareness about the importance of hydrography – the science of measuring and charting bodies of water. From ancient civilizations using basic instruments to modern technology mapping every inch of our oceans, hydrography has come a long way and plays a crucial role in ensuring safe navigation and protection of marine life. So let's dive into this exciting holiday and learn more about the fascinating world of hydrography!
