December's annual fall meeting of the American Geophysical Union presented another opportunity for specialists in everything from air pollution to the origin of Earth to immerse themselves in their narrow disciplines as well as cross into related areas. Overlap between disciplines can be peripheral but interesting, as in the examples below. The amount of salt in surface water can influence ocean circulation and thus climate, and water passing from the crust through sediments into the ocean can help control the concentration and composition of seawater salts.
12月举行的美国地球物理联盟年度秋季会议为从空气污染到地球起源等各个领域的专家提供了另一个机会，让他们既能专注于自己的细分学科，也能涉足相关领域。学科之间的交叉可能处于边缘地带，但却饶有趣味，如下文示例所示。地表水的含盐量会影响海洋环流，进而影响气候，而从地壳穿过沉积物进入海洋的水有助于控制海水中盐分的浓度和成分。
