Synopsis: Waterways & watercourses: Waterways: Lagoon:

Though Elerian lives in Laguna Beach California, near where Pimco is headquartered, he says that he can t name a single country as his own.

The lake has a number of lagoons and baymouth bars which are made formations of sand mud

 The 52.2-million-year-old tomatillo was discovered at the fossil-rich Laguna del Hunco Argentina where ancient lakebeds interlayer with volcanic ashes providing paleontologists with precisely dated discoveries.

During his talk he listed 11 fossils from Laguna del Hunco such as cycads trees and the tomatillo that show their molecular clocks are too young.

Ancient landscape An examination of the two cores one from the large lake Laguna Oricore and one from the smaller lake Laguna Granja revealed a surprise:

But the discovery of fossilized Agathis leaves branches and cones in the rich deposits at Argentina's Laguna del Hunco suggests the tree covered much more ground in prehistoric times.

The layers of volanic ash and lake sediments at Laguna del Hunco have turned up some other amazing ancient plants including a fossilized tomatillo and the remains of eucalyptus buds and flowers.

so they live in and around lagoons or lakes. These bodies of water tend to be saline or alkaline.

Ainara Sistiaga a graduate student at the University of La Laguna in Spain who led the investigation as a visiting student at the Massachusetts institute of technology said the results aren't all that surprising as Neanderthals are primates

's western lagoon. A limestone ridge thick with vegetation juts into the cloudless blue sky behind him.

Out of sight the autonomous underwater vehicle (AUV) an oceanographic workhorse called a Remus begins gliding through the lagoon in a pattern that resembles the long linear passes of a mowed lawn.

The U s. began with a furious air campaign that was designed to knock out Japanese vessels clustered in Palau's western lagoon

Bentprop calculates that eight American planes including A b-24 bomber remain hidden in Palau's western lagoon.

Mission photographs from WORLD WAR II show the fourth a Consolidated B-24 Liberator on a path toward the western lagoon.

and the western lagoon seemed the most likely location for them to have ended up. The identification number painted on the plane's exterior would have degraded by now;

Guided by GPS coordinates from the AUV Pat Colin director of the Coral reef Research Foundation pilots the vessel across the lagoon to the approximate location of the mystery plane.

The next day Bentprop compares the aircraft in the western lagoon with a hundred different vintage planes.

For now it still lies somewhere in the lagoons surrounding Palau concealed by water and time.

Animal waste is collected in lagoons where the gas is captured. The gas is transported through an internal combustion area that produces energy for heat and electricity.

They recommended dry lot and solid storage systems as preferred management strategies rather than anaerobic lagoons and deep bedding.

If we can put an anaerobic barrier at the point where a lagoon drains into the environment we will essentially exert selective pressure for the loss of antibiotic-resistant genes

and encircles three lagoons. Named after the American ship whose captain discovered it in 1802 Palmyra contains a 12-square-kilometer national wildlife refuge part of the larger Pacific Remote Islands Marine National monument established in 2009.

Mccauley's team decided to focus on how mantas use Palmyra's lagoons. Lagoons are known to be ecologically important to a variety of mobile species including manta rays sharks turtles and dolphins.

We used high-resolution animal tracking tools to describe in as much detail as we could the ecology of the mantas

Using a novel combination of research tools the scientists examined how the manta rays use lagoons

and go from Palmyra's lagoons. Very heavily used by mobile animals as breeding grounds and as places to feed lagoons are highly sensitive to human disturbance.

Although there is no evidence that Palmyra ever supported permanent indigenous settlements its habitats were affected dramatically during WORLD WAR II

Lagoons are imperiled often very places so that was certainly part of our interest Mccauley said. Palmyra's lagoons and the mantas that use them are protected.

However lagoons elsewhere have been compromised. Fishing boat traffic and habitat degradation all may negatively affect mantas in less remote lagoons.

The big question Mccauley and his team wanted to answer is why manta rays congregate in this particular habitat.

It turns out it was at least partially because of the food. The researchers used stable isotope analysis a chemical assay of a tissue biopsy that provides an integrative view of what the animal ate in previous months.

They matched the chemical signature of the mantas to that of zooplankton collected in the lagoons verifying that this habitat serves as an important feeding ground.

Using mathematical modeling we determined that many of the manta rays we encountered took around 80 percent of their energy from lagoon plankton Mccauley said.

This discovery that lagoons can contribute such an important amount of food and energy to manta rays highlights the need to motivate management interventions in lagoons.

Other tools in the researchers'arsenal were high-resolution tracking which provided information about how the manta rays used the lagoon habitat over long and short periods of time;

an acoustic camera which logged patterns of the animals entrances and departures from the lagoons;

and photo identification/laser photogrammetry--making measurements from photographs--which provided insight into whether the manta rays were staying in this habitat for longer time periods by tracking their comings and goings.

Additional detailed information about how manta rays use ocean areas outside of lagoons will also be needed to better manage this at-risk species. Story Source:

Among the technologies evaluated in situ are floor type in cattle housing use of additives in slurry storage manure turning flexible lagoons for collective slurry storage biowashers for gases at the outlet of air ducts of the sheds

The methane bubbling up from a single palm oil wastewater lagoon during a year is roughly equivalent to the emissions from 22000 passenger vehicles in the United states the analysis found.

For now the carbon footprint of cutting down forests to make way for palm plantations dwarfs the greenhouse gases coming from the wastewater lagoons.

But while deforestation is expected to slow as the focus shifts to more intensive agriculture on existing plantations the emissions from wastewater lagoons will continue unabated

The amount of methane biogas that went uncollected from palm oil wastewater lagoons last year alone could have met a quarter of Malaysia's electricity needs.

Capturing methane at wastewater lagoons could be encouraged by making it a requirement before palm oil products can be certified as sustainable the authors said.
