Carl Sagan - Pale Blue Dot

It is sometimes said that scientists are unromantic, that their passion to figure out robs the world of beauty and mystery. But is it not stirring to understand how the world actually works — that white light is made of colors, that color is the way we perceive the wavelengths of light, that transparent air reflects light, that in so doing it discriminates among the waves, and that the sky is blue for the same reason that the sunset is red? It does no harm to the romance of the sunset to know a little bit about it

NERC - Down in the bottom of the deep blue sea

NERC - Down in the bottom of the deep blue sea | Gaia Diary | Scoop.it
Deep sea covers most of our planet and yet we know more about the surface of the moon than its dark depths. Its inhabitants form ecosystems essential to life on earth and the race is on to understand and conserve it.

NERC funds scientists working to map the sea floor, examine its geology, currents, chemical processes and more. We hear from scientists on two huge projects - Deep Links and SO-AntEco - half a world away from each other, but with a similar quest: to understand the deep's diverse lifeforms.

We know the deep sea provides essential habitats and resources for countless species, many of which we rely on for food. But we also know that plastics are invading these systems and certain fishing practices can cause huge damage. Until we fill the gaps in our knowledge, we can't know the impact of human activity or what measures could protect these ecosystems.

To get that information, these scientists have been out on research ships being battered by the elements while they film, catch and preserve samples of marine life, working in shifts day and night to make the most of their time on board.

Uncovering changing climate in the UK's seas, coasts and oceans | Gaia Diary | Scoop.it
Climate change is having important effects on UK seas and coastlines and these have been brought together by the UK Marine Climate Change Impacts Partnership (MCCIP) in their report published today.

Sir David Attenborough said of the report:

Concern about the state of our seas has caused them to be studied more intensively - and extensively - than ever before. Here is a summary of the findings. They have never been more important.

#Archaeology: Citrus fruits were the clear status symbols of the nobility in the ancient Mediterranean | Gaia Diary | Scoop.it
New research from Tel Aviv University reveals that citrons and lemons were clear status symbols for the ancient Roman ruling elite and plots the route and evolution of the citrus trade in the ancient Mediterranean.

The study is based on a collection of ancient texts, art, artifacts, and archaeobotanical remains such as fossil pollen grains, charcoals, seeds, and other fruit remnants. It was led by archaeobotanist Dr. Dafna Langgut of TAU's Institute of Archaeology and The Steinhardt Museum of Natural History and recently published in HortScience.

Warm Antarctic caves harbour secret life: scientists

Warm Antarctic caves harbour secret life: scientists | Gaia Diary | Scoop.it
A secret world of animals and plants—including unknown species—may live in warm caves under Antarctica's glaciers, scientists said Friday.

The caves, hollowed out by steam from active volcanoes, are light and could reach temperatures of 25 degrees Celsius (77 Fahrenheit), researchers said, raising the possibility of a whole ecosystem of flora and fauna deep beneath the frozen surface.

A study led by the Australian National University around Mount Erebus, an active volcano on Ross Island in Antarctica, showed extensive cave systems.

Lead researcher Ceridwen Fraser said forensic analyses of soil samples from the caves had revealed intriguing traces of DNA from algae, mosses and small animals.

While most of the DNA was similar to mosses, algae and invertebrates found elsewhere in Antarctica, not all sequences could be fully identified.

"The results from this study give us a tantalising glimpse of what might live beneath the ice in Antarctica -– there might even be new species of animals and plants," she said.

"The next step is to go and have a really good look and see if we can find communities living beneath the ice in Antarctica."

Massive Antarctic volcanic eruptions linked to abrupt Southern hemisphere climate changes

Massive Antarctic volcanic eruptions linked to abrupt Southern hemisphere climate changes | Gaia Diary | Scoop.it
New findings published today in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) by Desert Research Institute (DRI) Professor Joseph R. McConnell, Ph.D., and colleagues document a 192-year series of volcanic eruptions in Antarctica that coincided with accelerated deglaciation about 17,700 years ago.

"Detailed chemical measurements in Antarctic ice cores show that massive, halogen-rich eruptions from the West Antarctic Mt. Takahe volcano coincided exactly with the onset of the most rapid, widespread climate change in the Southern Hemisphere during the end of the last ice age and the start of increasing global greenhouse gas concentrations," according to McConnell, who leads DRI's ultra-trace chemical ice core analytical laboratory.

Climate changes that began ~17,700 years ago included a sudden poleward shift in westerly winds encircling Antarctica with corresponding changes in sea ice extent, ocean circulation, and ventilation of the deep ocean. Evidence of these changes is found in many parts of the Southern Hemisphere and in different paleoclimate archives, but what prompted these changes has remained largely unexplained.

‘There are trees where to lay your eggs or where to find a safe cover; trees on which to look for food or, simply, to scratch your back and thus leave behind a trace of your passage’ – Bruno D’Amicis and Umberto EspositoAn inspired filmmaking experiment, One Tree, One Year observes a year in the life of a beech tree in Italy’s National Park of Abruzzo, Lazio and Molise. Filmed continuously through the changing seasons, the short documentary glimpses several species – including wild boar, Italian wolves and Marsican brown bears – passing by and interacting with the tree in a variety of ways, unaware of the camera. The result is a simple yet enchanting rejoinder to sensationalised nature filmmaking, and a marvellous distillation of the incredible complexity of ecosystems.Via Kottke.org
