摘要

地球的气候一直保持在“金发姑娘”条件下，因为各种反馈系统将大气中的二氧化碳分压维持在一个狭窄的范围内。与大气相比，海洋是一个巨大的碳库，在气候系统中起着关键作用，研究海洋过程可以帮助我们更好地理解这一系统。大气中产生的宇宙核素及其与地球对应核素的比率可以提供地球表面过程的详细描述，因此，自从有可能用加速器质谱法测量它们以来，它们已被广泛利用。铍同位素（10Be / 9Be）是用于此目的的最有用的同位素系统之一。本文综述了近年来铍同位素化学研究的最新进展，以及铍同位素与洋流和冰盖动力学的关系，以及铍同位素与长期气候的风化关系。

Beryllium Isotopes in Marine Science: Understanding Ocean Current and Ice Dynamics

The Earth's climate has been kept under Goldilocks conditions because a variety of feedback systems maintain the atmospheric pCO2 within a narrow range. The ocean, as a large reservoir of carbon compared with the atmosphere, plays a key role in the climate system, and studying ocean process can help us better understand this system. Cosmogenic nuclides produced in the atmosphere and their ratio to a terrestrial counterpart can provide detailed depictions of Earth surface process, and they have therefore been utilized widely since it became possible to measure them with accelerator mass spectrometry. Beryllium isotopes (10Be

$/$

9Be) are one of the most useful isotope systems for this purpose. In this article, we summarize recent developments in beryllium isotope chemistry and the isotopes’ relation to ocean current and ice sheet dynamics as well as weathering in relation to long-term climate.
