when life outside of the oceans began to diversify. At the beginning of the Triassic most of the continents were concentrated in the giant C-shaped supercontinent known as Pangaea.
Late in the Triassic seafloor spreading in the Tethys Sea led to rifting between the northern and southern portions of Pangaea
The oceans had been depopulated massively by the Permian Extinction when as many as 95 percent of extant marine genera were wiped out by high carbon dioxide levels.
The mid-to late Triassic period shows the first development of modern stony corals and a time of modest reef building activity in the shallower waters of the Tethys near the coasts of Pangaea.
Early in the Triassic a group of reptiles the Order ichthyosauria returned to the ocean. Fossils of early ichthyosaurs are lizard-like
By the mid-Triassic the ichthyosaurs were dominant in the oceans. One genus Shonisaurus measured more than 50 feet long (15 meters)
A photographer even snapped a shot of a croc cousin the American alligator (Alligator mississippiensis) in a tree about 4 to 6 feet (2 to 3 meters) above the water at the Pearl river Delta in Mississippi.
#Stress Makes Antarctic Penguins Less-Attentive Parents Stress induced by changes in Antarctic sea ice may cause adult male Adã lie penguins to be less attentive to their chicks and may increase chick mortality according to a new study.
Adã lie penguins#medium-size cousins of emperor penguins common along much of the Antarctic coastline spend lots of time on sea ice searching for the krill that they feed on in the water below.
In recent years changes in the distribution of sea ice have forced the penguins to travel farther
Adã lie penguins Cope with Changing Sea Ice Conditions. Changed ice more stress As the distribution of sea ice is projected to continue to change throughout the century as climate change progresses researchers based at the University of Strasbourg in France were interested in determining how this environmental stress may impact the future population of Adã lies on the southernmost continent.
The team traveled down to the eastern coast of Antarctica to observe a colony during a breeding season from Mid-november 2009 through Mid-february 2010
and captured and treated 10 adult males with pellets containing corticosterone a stress hormone common in birds.
But the new findings do add to the growing body of evidence suggesting penguin populations may shrink with future changes in sea ice.
But the problem in recent years would be the food availability and the sea-ice conditions in Antarctica.
Changes in sea-ice distribution hit one particular Adã lie colony hard this year: On eastern Antarctica's Petrel Island not a single chick has survived the 2013-2014 summer season among the 20000 breeding pairs that live there Thierry said.

The 1-month-old calf mummy named Lyuba was discovered in 2007 by a reindeer herder on the banks of a frozen river on the Yamal Peninsula in Siberia.
A mammoth-ivory hunter found the second mummy which researchers named Khroma after the river in Yakutia in which she was found frozen upright in permafrost.
The baby mammoth was likely crossing a frozen lake with her mother when she crashed through the ice
It was just a matter of minutes before she would have lost consciousness Fast-flowing river Khroma was also healthy
But Khroma had broken a back and mud from a fast-flowing river in her trachea.

#Massive Antarctic Glacier Uncontrollably Retreating, Study Suggests The glacier that contributes more to sea level rise than any other glacier on Antarctica has hit a tipping point of uncontrollable retreat

#Nearly 600 Years of Tree Rings Show Altered Ocean Habitat Ocean currents that deliver important nutrients to shallow coastal waters have become weaker and more variable over the last half-century
Data records spanning almost 600 years have shown that the strength of coastal upwelling off the west coast of North america has become more variable since 1950.
Researchers pieced together this long-term look at ocean trends from an unlikely source: tree rings. Coastal upwelling happens
when winter winds lift deep nutrient-rich waters up to the shallow layers of the sea.

Colorado river Reaches Gulf (Photos) For the first time in 16 years freshwater from the Colorado river has flowed into the salty waters of the Gulf of california.
On Thursday (May 15) a high tide surged past a stubborn sandbar and connected the river with the Sea of Cortez said Francisco Zamora director of the Colorado river Delta Legacy Program for the Sonoran Institute.
Because of water use upstream little flow from the 1450-mile Colorado river 2330 kilometers has reached the sea in 50 years.
Zamora watched the high tides make the final link between river and sea last week via a pilot channel dug by the Sonoran Institute to increase freshwater flow into the Gulf of california.
The freshwater comes from agricultural runoff and releases from wastewater treatment plants. The seawater ran north through the Rio Hardy a series of swampy wetlands and mudflats that drains 15 miles (24 km) downstream into Gulf waters.
Images: Colorado river Connects With Sea The reunion is the end of a 53-day journey for the long-planned Colorado river pulse flow an artificial flood meant to restore the river's parched delta.
The water comes from an international agreement called Minute 319. The plan allocates about 1 percent of the river's flow to a five-year experiment that will mimic spring floods in the delta.
The goal is bring back the plants and animals that once thrived in the river's outlet.
When the pulse flow was unleashed on March 23 from the Morales Dam scientists didn't know
if the water would enter the Gulf or remain in the river's broad delta.
Seeing the Colorado complete its journey broadens the project's restoration potential Zamora said. After waiting for two months it was very exciting to see Zamora told Live Science's Our Amazing Planet.
This pulse flow opens the door for new possibilities for restoring riparian and estuary habitats.
While much of the delta is choked with salt-loving tamarisk (an invasive salt cedar) now conservationists hope to see more riparian habitat growing after the pulse flow:
cottonwood and willow forests along with wetlands thick with cattail marshes. The flood was timed for the spring seed release from these trees to provide moist ground for seedlings.
Though the amount of water reaching the estuary habitat where river mixes with sea will likely be said small Zamora it could help the hundreds of bird species who nest in the Gulf
and perhaps even restore some species that had vanished from the estuary. I think everyone is excited very about the opportunities Zamora said.
While the study is unlikely to settle the scientific debate it does support the idea that Earth's global warming continues in the ocean even
whether ocean heat storage is responsible for the hiatus versus not enough heat reaching the surface of the Earth said study co-author Ka-Kit Tung of the University of Washington in Seattle.
Earth's Tallest Mountain to Deepest Ocean Trench Global storage closet Scientists have blamed the oceans for the global warming pause before
However in seeking to test this idea with temperature data oceanographer Xianyao Chen of the Ocean University of China in Qingdao
Tung and Chen then searched ocean by ocean until they hit on the North Atlantic where the heat was playing hooky The pair primarily relied on Argo floats which record ocean temperature
Unfortunately the massive array of ocean temperature measurements by Argo floats has only been made after the early 2000s just
So being conclusive about each ocean basin is limited by data availability. Tung and Chen noticed that the North Atlantic's heat content (a measure of stored energy) shifted in 1999 about
The ocean started absorbing heat at depths below 984 feet (300 m).(The South Atlantic ocean also took up some heat.
These regions stored more heat energy than the rest of the world's oceans combined even the enormous Pacific ocean the researchers'temperature data show.
The AMOC is part of a worldwide ocean conveyor belt. Here's how the AMOC works: In the North Atlantic salty tropical water flowing north cools off and sinks.
When the water sinks it traps heat in the ocean depths. Ocean surface temperatures drive the current:
fast when cold slow when warm. Images: The World's Biggest Oceans and Seas Between 1945 and 1975 the cycle was in a cool phase sucking up atmospheric heat at a rapid pace.
Toward the end of this cycle in the 1970s scientists noticed a suspected global cooling that was touted as the beginning of a possible Ice age.
Finally in 1999 the current switched back to a cold speedy plunge into the ocean depths taking extra heat along with it.
I still think the Pacific ocean is playing the lead role in this ocean heat uptake but this study is important as it points to an additional role from the Atlantic
and Southern Oceans said England who co-authored the Aug 3 Nature Climate Change study. Email Becky Oskin or follow her@beckyoskin. Follow us@livescience Facebook & Google+.
Rapid erosion of these mountains contributed large amounts of sediment to lowlands and shallow ocean basins.
Sea levels were high with much of western North america under water. Climate of the continental interior regions was very warm during the Devonian period and generally quite dry.
