冬天的海,泡沫汹涌

今天去Fort Funston. 漫天乌云十分壮观. 太平洋波浪愤怒,光影好象欧洲油画的效果.

每次来这里都有意外收获.这一次是满海滩的厚厚泡沫.好象整个海洋放满了洗衣粉,白白的泡沫溢到沙滩上来.大风吹拂中,泡沫象撕碎的棉絮翻滚着.有个金发小男孩,拿着小铲子,使出全身的劲奋力拍碎面前的泡沫,很有愚公移山的信念,快乐无比.

阳光很烈,风也很冷.我和桂紧紧抓着连帽杉的领子, 在海边顶着风边走边回忆当年在北京顶风骑车的情景,风和温度十分类似. 冬天的海在乌云阳光里翻滚咆哮. 堆满泡沫的海滩,居然很象雪地.不知道哪里冒出个穿列宁装戴六角帽的人来,更象西伯利亚了. 不时跳过吹跑过来的泡沫,不时有陌生友好的狗狗跑来把网球放在我们脚边,然后眼巴巴看着我们,要和我们玩扔球.有点超现实.好象过着别人的日子.

回来上网查了一下,这种泡沫不是很常见的.原来不是我们少见多怪. 去年在悉尼发生过类似的事情,卡帕西诺海岸泡沫更凶猛,可以盖过人.

Scientists explain that the foam is created by impurities in the ocean, such as salts, chemicals, dead plants, decomposed fish and excretions from seaweed.
All are churned up together by powerful currents which cause the water to form bubbles.
These bubbles stick to each other as they are carried below the surface by the current towards the shore.
As a wave starts to form on the surface, the motion of the water causes the bubbles to swirl upwards and, massed together, they become foam.

科学家的解释是泡沫来自海洋里的杂质,比如盐,化学元素,死去的植物,烂掉的鱼,和海藻的分泌物.被强大的暗流击打后致使水里生成气泡(Jean:大概就象打鸡蛋的原理?)气泡粘在一起被暗流带到岸边.在岸边形成海浪的过程中,气泡上升形成泡沫.

算污染么?
