... of experiments that suggest even modest levels of underwater sound could trigger bubble formation in a liquid of supersaturated nitrogen. The supersaturation levels can result in very large nitrogen bubbles, which could have potentially deleterious biological effects. Crum will present preliminary results of...... the Bible, forbidding the consumption of fish and underwater creatures without fins or scales, among other dietary restrictions. Throughout the world in different cultures and religions, a variety of dietary restrictions exist. The origin of these rules is often debated.

... Mid-Atlantic Ridge (MAR-ECO). Using sophisticated underwater vehicles and cameras, investigations plunge to depths of 6000 m along the abyssal plains of the sea floor (CeDAMar) and near vents and seeps (ChEss) where chemical energy, rather than sunlight, sustains life.
