Watch the water: Great Lakes' currents visualized


You can't normally see water currents or the wind.
Now you can: A computer code used to visualize wind has been adapted by researchers to show surface currents of the Great Lakes.

The code was originally developed to make a map of the wind by Fernanda Viégas and Martin Wattenberg, artists/technologists who lead Google's "Big Picture" visualization research group in Cambridge, Mass., according to their website.

 But researchers at the Great Lakes Environmental Research Laboratory in Michigan saw the stunning wind map and figured it could be applied to surface currents of the Great Lakes, which are largely driven by wind.
They were right.
And, luckily for them, Viégas and Wattenberg agreed to share their code.

The result? A stunning map of surface currents on the Great Lakes, as shown in this screenshot of the map on the laboratory's website from Oct. 3.

The code uses a computer model to visualize wind patterns, said David Schwab, a researcher at the laboratory who's in charge of the map.
The model is based on measurements of wind speed, air temperature and other variables at weather stations and buoys around the Great Lakes, Schwab told OurAmazingPlanet.
It's updated four times per day.

"I think a lot of people never realized how variable the currents are in the lakes," Schwab said.
He thinks the map will be useful for recreational boaters, fishermen and the shipping industry, as well as for generally increasing people's knowledge of the Great Lakes, he said.

Faster currents are shown as thicker white lines, and the speed of the current can be determined by zooming in on individual lines.

What the sea gives me


"The Sea, once it casts it spell, holds one in its net of wonder forever." Jacques-Yves Cousteau

From Kickstarter             

Misfit pictures welcomes all ocean lovers to join us in the creation of our next film WHAT THE SEA GIVES ME, a stunningly beautiful portrayal of the seemingly inexplicable relationship between ourselves and the sea.


Our film highlights individuals whose lives and destinies are defined by their connection to the ocean. Whether it be the extremely dangerous researching of Great White sharks, diving to depths never before reached, surfing death-defying mountains of water or humbly feeding your family from the day's catch - all of us are invisibly linked to the ocean in one form or another.

If you are still reading, I guess you know exactly what I am talking about.
But here's a little more.
WHAT THE SEA GIVES ME is a feature length documentary comprised of intimate and candid interviews with some of the ocean's most extraordinary ambassadors.
We will give you an honest and personal look through the eyes of those who thrive under the most extreme water conditions, those ensuring the proper care of the oceans for future generations and those who simply derive a sense of pure joy from the sea.

Proposed interviews include Great White shark researcher Brett McBride, artist Matt Beard, photographer Chris Burkard, bodysurfer Angie Oschmann, conservationist Jean-Michelle Cousteau, free-diver Herbert Nitsch, oceanographer Walter Munk and many others.
In addition to riveting personal interviews, we are filming in spectacular above-and-below-the-water locations around the world (South Africa, Greece, Fiji, Australia, Ireland, New England, California, and Hawaii) to display the natural beauty of the oceans.

The goal of WHAT THE SEA GIVES ME is to raise ocean awareness on a global level while reminding the viewer how closely we are all connected to the sea; and, to introduce you to an unique group of people we find absolutely captivating.

Sea change: a tidal journey around Britain - interactive

 “... a sense of threat as well as one of miracle attends Marten’s images. The people who fill his beaches at low tide seem often still to be there at high tide, invisibly in their fixed positions, fatally swallowed by metres of sea.”- Robert Macfarlane

From TheGuardian

Photographs of the same locations taken at high and low tide make for a series of fascinating diptychs


Since 2003 photographer Michael Marten has travelled around the British coast to photograph identical views at high and low tide, six or 18 hours apart.
St Cwyfan's, Anglesey: 'At midday, the church looks isolated and austere beneath a grey, rain-threatening sky. Later, the clouds are paler and kinder.'
Photograph: Michael Marten

See how the seascapes in his photographs are dramatically transformed by clicking on the vertical slider in the middle of the image and moving it left or right.







The British landscape photographer Michael Marten is, in his own words, "a student of tides".
In 2003, he spent a day photographing a set of rocks on the coast of Berwickshire and, afterwards, while reviewing his pictures, he realised that he had captured the same view at ebb and flood tide.
He realised, too, that the incoming sea had radically altered the perspective and the atmosphere of that stretch of landscape.

 Hayle river mouth, Cornwall. 18 March 2010.
Low water 12 noon, high water 6pm.

So began the nine-year journey around Britain's coastline that is distilled into the 105 colour images in Sea Change, a body of work that records landscapes defined by these two contrasting moments in time.

Marten's preparation for each set of photographs was painstaking.
He scanned tide-table charts and local coastal maps to find the best locations to set up his 5x4 camera and the exact times when the tide was at its lowest and highest.
"When I take the first picture of a tidal pair," Marten writes in his afterword, "I mark the position of my tripod with sticks and stones or scratch marks on rocks so that I can set up in the same position six hours later or the next day. I place a sheet of tracing paper on the ground glass screen of the 5x4 camera and, under my darkcloth, use a pencil to trace lines that will remain unchanged when the tide comes in or goes out: the horizon, a rock, a harbour wall, or distant headland."
Thus, the second image is meticulously framed exactly like the first.
The end result is a book of intriguing diptychs: some torrential; some busy, then deserted; some so radically different in atmosphere and detail that they seem to be entirely different landscapes.
Put simply, the sea changes everything, not just the land it covers, but the land around and beyond it.

Bedruthan Steps, Cornwall. 25 and 31 August 2007.
High water 4.30pm, low water 2pm

Marten is also a master of tone and colour, and the photographs speak of the elements as much as the sea and the shore.
In Aberffraw on Anglesey, he captures St Cwyfan's church – known locally as "the church in the sea" – at midday at high water on 9 April this year.
It looks isolated and austere beneath a grey, rain-threatening sky, a place not so much of refuge as of pure isolation.
At 5.45pm on the same day, the tide has retreated way beyond the raised stone mound that the church squats on, and the clouds are paler and kinder.
The church looks part of the landscape, the same sandy colour as the sand and pebbles in the foreground. It also looks welcoming.

 Salmon fishery, Solway Firth. 27 and 28 March 2006.
Low water 5.20pm, high water 12 noon

There are diptychs of tidal estuaries, famous beaches, coves, ports and crags that jut into the sea.
There is even a diptych of Crosby, Liverpool, where the artist Antony Gormley's cast-iron men stand submerged in water, then alone on a long, wide expanse of sand.
They look defiant even as the tide rises around them and over them.

As Robert McFarlane notes in his illuminating introductory essay, one of the most powerful aspects of Marten's photographs is "the cognitive dissonance between the serene and the sinister".
As sea levels rise inexorably, these beautifully strange images are ominous too in their evocation of what may come.

Image of the week : Patagonia

>>> geolocalization with the Marine GeoGarage <<<

From NASA

Clouds hovered off the coasts of Patagonia near dawn on a beautiful early spring day 2012, allowing a rare cloudless view of the dramatic landscape of the region.
The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite captured this striking image on September 24, 2012 at 19:05 UTC (6:05 a.m. Chile Summer Time).

Patagonia is a term used for the rugged region that comprises the southern end of South America, and includes parts of Chile (west) and Argentina (east).
Although black borderlines have not been overlaid on this image, the border between the two countries is roughly delineated by the western side of the Andes Mountains, which run from north to south and are snow-capped in this image.

One of the most striking features along the Chilean-Andean border is a series of bright blue glacial lakes.
From north to south these are Lake O’Higgins/San Martín, Viedma Lake and Argentino Lake.
The southernmost portion of this mountain range remains quite cold year round, and gives a home to the largest ice fields in the Southern hemisphere outside of Antarctica.
Moving east from the tower Andes the land gives way to vast steppe-like plains, while in the west the foliage is strikingly verdant, even in early spring.

Springtime in Patagonia, like spring in most places, in a time of change and rebirth.
The wildflowers bloom in abundance, including a stark red, dramatic plant known as the Chilean firebush.
Birds are on the move, with migration well underway.
By November, about 150,000 Magellanic penguins will return to the Chilean coast to raise their young.
It is also springtime which brings the birth of baby guanacos, a lama-like species found most commonly in Patagonia.
