Caption from Polar Discovery: The Van Veen grab collects sediment from the ocean floor. It's lowered on a cable until it hits the bottom. Then it closes, scooping up sediment from the bottom-in this case, mud-between its two halves.
Image Of the Day repeat caption:
A Van Veen grab is lowered to the seafloor, where the two halves of the scoop will close, "grabbing" a large scoop of sediment and any organisms living in it. Sediment grabs are a versatile and inexpensive method for collecting samples from the ocean floor. Van Veen grabs can be deployed easily from a dock or a ship. WHOI scientists have used them to study sediment from the Bering Sea (pictured) to investigate how climate change may be affecting Arctic Ocean ecosystems, and to look for human pathogens in sediments of Massachusetts waterways.

The Van Veen grab collects sediment from the ocean floor. The instrument is lowered on a cable until it hits the bottom. When it closes, it scoops up sediment--and animals living in the sediment--between its two halves. During this April/May 2009 cruise in the Bering Sea, researchers were studying how climate change is affecting the Arctic Ocean ecosystem.
