LIVE SCIENCE : MASSIVE SYSTEM OF ROTATING OCEAN CURRENTS ACTING STRANGELY
Excerpt: An analysis of clam shells suggests the North Atlantic subpolar gyre has had two periods of destabilization over the past 150 years: one around 1920 and the other from 1950 through present. ....
"It's highly worrying," study lead author Beatriz Arellano Nava, a postdoctoral research fellow in physical geography at the University of Exeter in the U.K., told Live Science. "The subpolar gyre was recently acknowledged as a tipping element. We still need to understand more of the impacts of a subpolar gyre abrupt weakening. But what we know so far with the few studies that have been published is that it would bring more extreme weather events, particularly in Europe ... and also changes in global precipitation patterns."
.... But the other signal was a total surprise, she said. The clam data revealed that the subpolar gyre was unstable for a few years in the run-up to the 1920s North Atlantic regime shift. This previously described event was characterized by the strengthening of currents in the gyre. Instability in the subpolar gyre likely caused the 1920s regime shift, and the timeline suggests the period of instability may have reflected the subpolar gyre's recovery from its Little Ice Age collapse, Arellano Nava said.

ENDANGERED POD IN PUGET SOUND - FIRST BIRTH OF BABY ORCA IN 2 YEARS
SCIENCE RECORDER - RARE NEWBORN BABY ORCA OFF WASHINGTON COAST full article from early January 2015...
This is good news for the pod, which has not seen a new addition to its community in more than two years.
Balcomb was monitoring the pod, known as J-pod, in the Puget Sound when he noticed the just-born baby orca, dubbed J-50 for now.
According to Brad Hanson, a wildlife biologist with the National Oceanic and Atmospheric Administration (NOAA), the birth of the baby whale is an encouraging sign for the pod, which was listed as endangered in 2005, a report by Live Science said. This is especially true since the pod lost a pregnant female earlier in December, probably caused by a bacterial infection following the death of her fetus.
“The loss of J-32 was a disturbing setback,” Hanson told Live Science. “We lost a lot of reproductive material.”
Balcomb does not yet know which whale is the calf’s mother—it could be an older 43-year-old female called J-16, who has given birth to three other surviving calves, or a younger whale, J-36, according to the Live Science report. Sadly, deaths among newborn killer whales are not uncommon. About 35 to 45 percent of all newborn orcas fail to survive past their first year, according to NOAA.

AQUANAUT JAMES CAMERON FINDS DEEP SEA LIFE
CAMERON FINDS WEIRD DEEP SEA LIFE : LIVE SCIENCE from December 6, 2012 Live Science
...The discovery of microbial mats — bizarre-looking, filament- like clumps of microorganisms — living off chemicals from altered rocks 35,803 feet (10,912 meters) beneath the surface of the Pacific Ocean comes from samples and video collected by an unmanned lander, part of movie director James Cameron's mission to the bottom of the Mariana Trench..."

MASS EXTINCTION OF LIFE ON EARTH BEFORE - AND AGAIN?
FOSSIL EVIDENCE UNDER THE SEA !
Will it happen again in our lifetime?
"Some scientists have speculated that effects of humans - from hunting to CLIMATE CHANGE - are fueling another great mass extinction. A few go so far as to say we are entering a new geologic epoch, leaving the 10,000-year-old Holocene Epoch behind and entering the ANTHROPOCENE EPOCH, marked by major changes to global temperatures and ocean chemistry, increased sediment erosion, and changes in biology that range from altered flowering times to shifts in migration patterns of birds and mammals and potential die-offs of tiny organisms that support the entire marine food chain."
