Because water expands as it warms, that heat also meant that sea surface heights were record high, measuring about 2.75 inches higher than at the beginning of the satellite altimeter record in 1993.

Smaller, dispersed droplets are less threatening for two reasons: they present more surface area to the water, so ocean bacteria can degrade the oil faster; plus, the small droplets are much slower to rise to the surface, keeping the oil at sea instead of in coastal wetlands and giving the bacteria more time to do their magic.

But sea surface temperatures in tropical areas are now warmer during today's La Niña years (when the water is typically cooler) than during El Niño events 40 years ago, says study coauthor Terry Hughes, a coral researcher at James Cook University in Townsville, Australia.

Titan is the only place in the solar system, besides Earth, that has large bodies of liquid on its surface, though its seas are composed of hydrocarbons such as methane rather than water.

Globs of decomposed fish flesh recently rose from deep in the Salton Sea, coagulated into spheres on the lake surface and surfed the waves to shore, leaving the high - water line littered with thousands of sticky balls of fish

The movement of water in the ocean is determined by many factors including tides; winds; surface waves; internal waves, those that propagate within the layers of the ocean; and differences in temperature, salinity or sea level height.

Some of these biomarkers are produced by certain species of algae, among which one group can only be found in open surface water, while the members of another group only live in sea ice (or did so in the Earth's distant past).

After they die, their detritus slowly sinks from the surface to the sea floor, and there is a layer in the water column, the OMZ, where microbes consume much of the detritus, a process that depletes oxygen through bacterial respiration.
