Climate change: Concerns over report on ocean heating

Environment correspondent

Errors have been found in a recent study suggesting the oceans were soaking up more heat than previously estimated.
The initial report suggested that the seas have absorbed 60% more than previously thought.
But a re-examination by a mathematician showed that the margin of error was larger than in the published study.
The authors have acknowledged the problem and have submitted a correction to the journal. Continue reading


Climate change will shift the oceans’ colors

In the next century, satellites will watch as the ocean’s blues and greens intensify.

By Sarah Gibbens
By 2100, The ocean as we know it is likely to change color.

That was the conclusion of a study published Monday in the journal Nature Communications that modeled how phytoplankton will change as oceans continue to warm. Under a “business-as-usual” scenario in which greenhouse gas emissions continue unabated, the bluest subtropical zones of the ocean will become bluer, and greener regions along the equator and poles will become greener.

A project presented by Damien DhontPhilippe LattesDenis Levaché & Arnaud Vidal

A large percentage of the world’s yet-to-find oil and gas resources lie under the seabed. Offshore exploration may be critical, but it poses major challenges: its high costs in particular make it difficult to carry out. That’s why it’s important to develop agile, selective technologies to locate promising emerging basins more efficiently, conquering this new offshore acreage cost-effectively. An example is the Glide project, in which a subsea glider equipped with special sensors detects natural hydrocarbon seepage in the water column. This innovation, a world first in the deep offshore, makes our exploration more efficient while cutting costs and HSE risks.

Scientists: Strong evidence that human-caused climate change intensified 2015 heat waves

Human-caused climate change very likely increased the severity of heat waves that plagued India, Pakistan, Europe, East Africa, East Asia, and Australia in 2015 and helped make it the warmest year on record, according to new research published today in a special edition of the Bulletin of the American Meteorological Society.

The prefifth edition of Explaining Extreme Events from a Climate Perspectiveoffsite link sents 25 peer-reviewed research papers that examine episodes of extreme weather of 2015 over five continents and two oceans. It features the research of 116 scientists from 18 countries analyzing both historical observations and changing trends along with model results to determine whether and how climate change may have influenced the event.

GOES-R Satellite Data: Analyze Severe Weather Events Like Never Before

We are looking forward to providing customers with GOES-R’s advanced capabilities to significantly improve the observation and detection of weather phenomena. GOES-R is a next-generation weather satellite that brings advanced resolution when viewing weather, along with a number of features including faster coverage, enhanced tornado and hurricane detection, real-time mapping of lightning—the first operational lightning mapper ever flown in space—solar flare monitoring and much more. It’s the most advanced weather satellite to date, and is equipped with significant features that will improve weather forecasting in the United States.

GOES-R will be the first of four satellites (R/S/T/U) that will extend the GOES satellite system through 2036. Upon successful launch and placement into geostationary orbit, GOES-R will be known as “GOES-16”. To see photos of the satellite, read the latest from Spaceflight Now.

If all goes as planned, the GOES-R satellite will be launched on November 19, 2016 at 5:42 p.m. Eastern Time. As of the latest updates, the weather is expected to be favorable for launch.


Data that will be available:

We plan to initially deploy Cloud & Moisture imagery from the GOES-R ABI (Advanced Baseline Imager), as well as Lightning Detection and Alerting from the GLM (Geostationary Lightning Mapper).

  • ABI Cloud & Moisture imagery will be available from the satellite beginning in early 2017. Both visible and infrared satellite data will be available, ranging from full-disk updates every 15 minutes and CONUS every 5 minutes, to mesoscale regions every 30 seconds. Resolution will range from 2 km IR full-disk to as high as ½ km visible in the mesoscale regions. Cloud & Moisture imagery includes digital maps of the observed land, water and clouds.
  • Beginning in mid-2017, real-time lightning data from the GLM will enhance our lightning detection/alerting capabilities for the western hemisphere.

In the future, we will be supporting additional GOES-R data products, including a variety of value-added data fusion products that will integrate GOES-R with other data sources like dual-polarity weather radar.

Here’s a preliminary look at how GOES-R Rapid-Scan Visible Satellite Imagery can be visualized in Baron Lynx, produced as a test and distributed to customers, using the in-orbit GOES-14 satellite during its experimented Rapid Scan period.
