Silence Your Ships

Anthropogenic (manmade) sound is creating havoc among marine mammals and other aquatic species. These creatures have very sensitive hearing, which they rely on to find food and mates and (for some) to communicate and navigate. Sound waves can travel much further and with much less loss of strength in water than in air. In pre-industrial times, the oceans were relatively quiet. Sailing ships generated almost no subsurface noise. A whale’s call could be heard by another whale hundreds of miles away in ambient conditions. The substantial and growing amount and volume of anthropogenic noise in the

By 2020, the subsea sector of oil exploration and extraction is expected to account for 20% of total crude oil production. In addition, global marine fisheries, which provide 15% of all animal protein consumed by humans, have been steadily collapsing for the last half century.

Scientists Uncover Explanation for Hidden Ocean Swell Interactions

Better simulations of internal tides may benefit sonar communications, protect offshore structures, and more.   In certain parts of the ocean, towering, slow-motion rollercoasters called internal tides trundle along for miles, rising and falling for hundreds of feet in the ocean’s interior while making barely a ripple at the surface. These giant, hidden swells are responsible for alternately drawing warm surface waters down to the deep ocean and pulling marine nutrients up from the abyss.   Internal tides are generated in part by differences in water density, and created along
