the tide sometimes comes right up to the base of the cliffs, so clay is being exposed and running into the ocean, where it gets suspended in the water and creates this cool white cloudy effect. (the clay is white because it's free of biological impurities, which are what turns must clay gray and black.) plus we had a record-breaking rainstorm in the area last week, which probably did a lot more erosion as well
long island is mostly made of glacially deposited sediment, but underneath it all is a lot of clay, the original material of the area. in most places that layer is below sea level, but along the north shore, there are hills which were pushed up by advancing glaciers, bringing that layer up. now erode into those hills, and what do you get? exposed 100 million year old clay!!!
