It is difficult to determine the effects of straw-break surface on the structure of drifting sand current and the wind speed profile in the sand-moving region due to the complexity of straw-breaks.

Unlike floating ice shelves which have little impact on sea level when they break up, the ice sheet is anchored to bedrock will blow the sea surface.

当浮动冰架破裂时，对海平面的影响很小；而与之不同的是，固定在基岩上的冰盖将会使海面炸毁。

"We know that surface use of dispersants decreases the environmental risk to shorelines and organisms at the surface and we know that dispersants break down over weeks rather than remaining for several years as untreated oil might."

This type of tag, however, requires a buoy to carry the aerial, and this is attached to the shark by a ten-metre-long line. (The line is needed because the sharks themselves rarely break the surface, and the transmitter cannot signal to the satellite from under water.) Two American biologists, Scott Eckert and Brent Stewart, from the Hubbs-Sea World Research Institute in San Diego, have had some success with satellite tracking.

It is possible that larger seeps at different times and locations might in fact be vigorous enough to break through the ocean surface.

Where the rainbow fringes become most tightly spaced is where the fault break came closest to the surface, although the data indicates the fault is unlikely to have broken right through to the surface.
