The distortion of the ancient shoreline and flooding surface of the US Atlantic Coastal Plain are the direct result of fluctuations in topography in the region and could have implications on understanding long-term climate change, according to a new study....

While 99 percent of Earth's land ice is locked up in the Greenland and Antarctic ice sheets, the remaining ice in the world's glaciers contributed just as much to sea rise as the two ice sheets combined from 2003 to 2009, says a new study....

A new study suggests that the previous connections scientists made between ancient shoreline height and ice volumes are erroneous and that perhaps our ice sheets were more stable in the past than we originally thought. The study found that the Earth's hot mantle pushed up segments of ancient shorelines over millions of years, making them appear higher now than they originally were millions of years ago....

A fish ladder is a structure that allows migrating fish passage over or around an obstacle on a river

The survival of many fish species depends on migrations up and down rivers. Among anadromous fish such as salmon, shad, and sturgeon, downstream migration is a feature of early life stages, while upstream migration is a feature of adult life. Among catadromous, like the North American eel, the opposite is true. River obstructions such as dams, culverts, and waterfalls have the potential to slow or stop fish migration. Indeed, these impediments to fish migration are often implicated in the decline of certain fish stocks.

Bivalves even make their own shells. An internal organ called the mantle secretes calcium carbonate so that as the inner invertebrate grows, the outer shell provides a roomier home.

A fish ladder, also known as a fishway, provides a detour route for migrating fish past a particular obstruction on the river. Designs vary depending on the obstruction, river flow, and species of fish affected, but the general principle is the same for all fish ladders: the ladder contains a series of ascending pools that are reached by swimming against a stream of water. Fish leap through the cascade of rushing water, rest in a pool, and then repeat the process until they are out of the ladder.

Climate change has been impacting global fisheries for the past four decades by driving species towards cooler, deeper waters, according to scientists....

New research shows that, in recent decades, fall is the only period of extensive warming over the entire Antarctic Peninsula, and it is mostly from atmospheric circulation patterns originating in the tropics....

NOAA recently launched and operated an Unmanned Aircraft System aboard the NOAA ship Nancy Foster. This was one of the first missions of its kind to be conducted from a NOAA ship.

Limiting the amount of warming experienced by the world's oceans in the future could buy some time for tropical coral reefs, say researchers....

Remains of endangered Hawaiian petrels -- both ancient and modern -- show how drastically today's open seas fish menu has changed. Scientists analyzed the bones of Hawaiian petrels -- birds that spend the majority of their lives foraging the open waters of the Pacific. They found that the substantial change in petrels' eating habits, eating prey that are lower rather than higher in the food chain, coincides with the growth of industrialized fishing....

Oceanographers used data from seafloor seismometers to analyze more than 300,000 fin-whale calls. By triangulating the position they created more than 150 tracks off the Pacific Northwest coast....
