一、前言海水pH是研究海洋二氧化碳系统的一个重要参数。pH在确定海洋和沿岸径流沉降作用和其它的地球化学过程中又起着重要作用(Mackenzic and Garrels 1966;Garrels andMackenzic 1967;Sillen 1967;Stumn and Morgan 1970)。河口与大洋相比,夏季因河水径流影响使pH变化较复杂,这种变化或许由决定碳酸盐介离常数的温盐变化所决定。本文将讨论这方面的问题。
I. INTRODUCTION Sea water pH is an important parameter for studying marine carbon dioxide system. pH plays an important role in determining runoff subsidence and other geochemical processes in the oceans and coasts (Mackenzic and Garrels 1966; Garrels and Maskenzic 1967; Sillen 1967; Stumn and Morgan 1970). Compared with the ocean in the estuary, the change of pH in summer is more complicated due to the effect of river runoff, which may be determined by the change of temperature and salt which determines the dielectric constant of carbonate. This article will discuss the issues in this area.
