Marine science began when the first human species walked out of the African savannah and came across a huge body of water. As these humans primarily dominated the landmasses, the question of water travel emerged as humans evolved and started looking for alternate means of exploration. For eons, the deep, dark ocean remained a mystery, but during the 20th century, scientists began exploring the marine environment as never before. "Marine Science: Decade by Decade" documents the history of this science throughout the 20th century. From Swedish hydrographer Otto Pettersson and the establishment of the International Council for the Exploration of the Sea to Wallace Broecker's breakthrough understanding of the oceanic conveyor belt, this volume highlights the progression of this fascinating science.
