Abstract

Abstract

The phenomena of hypoxia and acidification in river estuary and offshore areas are increasing influenced by the anthropogenic activities and global change. The problem has being a hot topic in scientific researches and aroused an extensive attention. This is a review about the marine hypoxia and acidification indicated by microscopic features in the benthic foraminiferal tests, and summarized the theoretical basis and methods of these indicators using on the test features (diameter and weight), pore features (density, size and shape), test ornamentation (teeth and/or tubercules, flaps), test dissolution and abnormal tests caused by the recalcification, and identified the interference factors in the results. We have pointed out several problems needed to pay more attention in the future researches, raised some operable advices and research orientations. The paper also aimed to more exactly use the indicators mentioned above in the future studies of our coastal hypoxia and acidification environment, and be used in the similar palaeoenvironmental evolution.
