Study: Oceans Trapping Heat at Accelerating Rate

WASHINGTON -- The amount of man-made heat energy absorbed by the seas has doubled since 1997, a study released Monday showed.

Scientists have long known that more than 90 percent of the heat energy from man-made global warming goes into the world's oceans instead of the ground.

And they've seen ocean heat content rise in recent years. But the new study, using ocean-observing data that goes back to the British research ship Challenger in the 1870s and including high-tech modern underwater monitors and computer models, tracked how much man-made heat has been buried in the oceans in the past 150 years.

NASA Finds New Way to Track Ocean Currents from Space

NASA's GRACE satellites (artist's concept) measured Atlantic Ocean bottom pressure as an indicator of deep ocean current speed. In 2009, this pattern of above-average (blue) and below-average (red) seafloor pressure revealed a temporary slowing of the deep currents. Image credit: NASA/JPL-Caltech

jpl.nasa.gov - November 2nd, 2015

A team of NASA and university scientists has developed a new way to use satellite measurements to track changes in Atlantic Ocean currents, which are a driving force in global climate. The finding opens a path to better monitoring and understanding of how ocean circulation is changing and what the changes may mean for future climate.

CLICK HERE - PAPER - Exceptional twentieth-century slowdown in Atlantic Ocean overturning circulation

washingtonpost.com - by Chris Mooney - September 24, 2015

. . . we learned from the National Oceanic and Atmospheric Administration that the first eight months of 2015 were the hottest such stretch yet recorded for the globe’s surface land and oceans, based on temperature records going back to 1880. . . .

In the North Atlantic Ocean south of Greenland and Iceland, the ocean surface has seen very cold temperatures for the past eight months. . . .

. . . And while there may not yet be any scientific consensus on the matter, at least some scientists suspect that the cooling seen in these maps is no fluke but, rather, part of a process that has been long feared by climate researchers — the slowing of Atlantic Ocean circulation.

Ocean Fish Populations Cut In Half Since The 1970s: Report

CLICK HERE - Living Blue Planet Report 2015

Populations of some commercial fish stocks, such as a group including tuna, mackerel and bonito, had fallen by almost 75 percent.

huffingtonpost.com - by Andy Campbell - September 16, 2015

A disturbing new report published by the World Wildlife Fund found that the world marine vertebrate population declined by 49 percent between 1970 and 2012.

The Living Blue Planet Report -- analyzed by the Zoological Society of London and issued as an update on our oceans' health -- also found that local and commercial fish populations have been cut in half, tropical reefs have lost nearly half of their reef-building coral, and there are 250,000 metric tons of plastic in our oceans.

Up in Maine, lobsters are thriving. The Atlantic States Marine Fisheries Commission reported last month that stocks there have reached a record high.

Down the coast, however, the story is different.

Ebola activity heats up as West Africa's rainy season begins

CIDRAP NEWS by Lisa Schnirring                                                                               June 3, 2015

(Scroll down for WHO stuation report.)

In  its weekly epidemiologicpidemiologic profile of the outbreak Wednesday, the World Health Organization (WHO) said Ebola activity in Guinea and Sierra Leone has become more intense and widespread since May 10, when the region saw cases hit a 10-month low.

Last week the two countries reported 25 new lab-confirmed cases, 13 in Guinea and 12 in Sierra Leone. The number is up from 12 reported the week before.

Overall, the total of confirmed, probable, and suspected cases in the two countries and Liberia—which is now Ebola free—has risen to 27,145, including 11,147 deaths, the WHO said.

Revealed: The Ocean's Tiniest Life At The Bottom Of The Food Chain

Plankton collected in the Pacific Ocean with a 0.1mm mesh net. Seen here is a mix of multicellular organisms — small zooplanktonic animals, larvae and single protists (diatoms, dinoflagellates, radiolarians) — the nearly invisible universe at the bottom of the marine food chain.

What's at the bottom of the bottom of the food chain? Well, think small ... smaller than you can see.

Tiny life forms in the ocean, too small for the naked eye to see.

Planetary Boundaries 2.0 – new and improved

As Science publishes the updated research, four of nine planetary boundaries have been crossed

Four of nine planetary boundaries have now been crossed as a result of human activity, says an international team of 18 researchers in the journal Science (16 January 2015). The four are: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles (phosphorus and nitrogen).

A team of scientists, in a groundbreaking analysis of data from hundreds of sources, has concluded that humans are on the verge of causing unprecedented damage to the oceans and the animals living in them.

“We may be sitting on a precipice of a major extinction event,” said Douglas J. McCauley, an ecologist at the University of California, Santa Barbara, and an author of the new research, which was published on Thursday in the journal Science.

NOAA-led study shows Alaska fisheries and communities at risk from ocean acidification

Petersburg Harbor.Image: Petersburg Harbor.

research.noaa.gov - July 29th, 2014

Ocean acidification is driving changes in waters vital to Alaska’s valuable commercial fisheries and subsistence way of life, according to new NOAA-led research that will be published online in Progress in Oceanography.

Many of Alaska’s nutritionally and economically valuable marine fisheries are located in waters that are already experiencing ocean acidification, and will see more in the near future, the study shows. Communities in southeast and southwest Alaska face the highest risk from ocean acidification because they rely heavily on fisheries that are expected to be most affected by ocean acidification, and have underlying factors that make those communities more vulnerable, such as lower incomes and fewer employment opportunities.
