The ocean is a vast and complex ecosystem, influenced by numerous environmental parameters that shape its dynamics and biodiversity. Understanding these parameters is crucial for managing and preserving our marine resources. In this article, we will explore a comprehensive list of English vocabulary related to marine environmental parameters, providing you with essential knowledge to navigate the world of oceanography and marine science.

4. pH: A measure of the acidity or alkalinity of seawater. pH levels influence the growth and development of marine organisms, particularly those with calcium-based shells. Shifts in oceanic pH due to rising carbon dioxide levels can have detrimental effects on coral reefs and other marine life.4 I2 D* n: w2 T' D9 Z; |$ f
