제1장 ‘바다의 세계’에서는 인간에게 있어서 바다란 어떠한 존재인가, 인간은 어떤 경로를 통해 연안에서 원양으로, 얕은 바다에서 심해로 진출하게 되었는가를 소개했다. 그리고 최초의 바다 탐험이 터무니없는 모험 가득한 항해로 시작되었다는 것과 오늘날에 이르러 심해가 얕은 바다와 마찬가지로 어떻게 연구 대상이 되었는지 그 경위를 기술했다. 제2장 ‘생동하는 바다’에서는 바닷물의 화학적 성질과 에너지와의 관련, 해양과 대기 간의 물질과 에너지의 순환, 파도와 해류(海流), 대순환에 대하여 물리학적 관점에서 해양의 특성을 설명하였다. 제3장 ‘바다와 기후’에서는 기후와 해양의 관련성, 특히 바다의 물리적 에너지와의 관련성과 그 에너지의 이용에 관하여 설명하였다. 제4장 ‘바닷속의 물질 교대’에서는 태양 에너지가 화학 에너지로서 먼저 식물에 흡수되어 에너지 물질로 체내에 축적됨과 동시에 생체 물질의 합성에 이용되는 과정, 증식한 식물이 동물에게 섭취되는 과정, 동물이 증식하게 되는 물질 교대의 과정을 설명했다. 제5장 ‘바다의 생물자원’에서는 어류와 고래, 새우 등 바다생물의 특징과 서식 환경, 먹이를 기술하였다. 제6장 ‘바다의 광물 자원’에서는 심해저에 부존되어 있는 망간 단괴, 코발트 크러스트, 메탄 하이드레이트 등의 실태와 탐사, 그리고 인양 기술을 소개하였다. 제7장 ‘심해의 세계’에서는 해저의 구조, 심해를 보는 방법, 해저 산맥, 깊이와 지자기 등을 소개하였다. 제8장 ‘바다와 인간의 하모니’에서는 해양이 인간과 어떠한 관계를 유지하고 있는지, 또 바다 자원의 실태와 그 보권, 해양 오염이 바다 자원에 미치는 피해 등을 설명하여 바다의 소중함을 일깨워 주고 있다.
