Sea-Level Rise Will Continue To Fuel Destructive Coastal Flooding
2013-12-05 10:26:23

April Flowers for redOrbit.com - Your Universe Online Two new literature review studies, published in Nature, reveal changing coastal ocean functions. The first study, "Coastal flooding by tropical cyclones and sea-level rise," reveals that the clamor about whether climate change will cause increasingly destructive tropical storms may be overshadowing a more unrelenting threat to coastal property: sea-level rise. Jonathan D. Woodruff, an assistant professor of sedimentology and...

Ocean Acidity Having Major Impact On Arctic Food Web Species

April Flowers for redOrbit.com - Your Universe Online Tiny crustaceans, known as copepods, live just beneath the surface of the ocean. A research expedition to the Arctic, part of the Caitlin Arctic Survey, found that these tiny animals are more likely to battle for survival if ocean acidity continues to rise. The study, published in Proceedings of the National Academy of Sciences (PNAS), revealed that copepods that move large distances, migrating vertically across a wide range of pH...

Diorite is a grey to dark grey intermediate intrusive igneous rock composed principally of plagioclase feldspar (typically andesine), hornblende, and/or pyroxene. Varieties deficient in hornblende and other dark minerals are called leucodiorite. It is often described as "salt and pepper" when composed largely of light-colored minerals randomly interspersed with dark minerals. When olivine and more iron-rich augite are present, the rock grades into ferrodiorite, which is transitional to...

Gabbro is a dark, coarse-grained, intrusive igneous rock chemically equivalent to basalt. It is a plutonic rock, formed when molten magma is trapped beneath the Earth's surface and cools slowly into a hard, coarsely crystalline mass. It is dense, greenish or dark-colored and contains varied percentages of plagioclase feldspar, pyroxene, amphibole, and olivine (called olivine gabbro when olivine is present in large quantities). Quartz gabbros are also known to occur and are probably derived...

Syenite is a coarse-grained intrusive igneous rock of the same general composition as granite but with the quartz either absent or present in relatively small amounts. The feldspars are alkaline in character and the dark mineral is usually hornblende. Soda-lime feldspars may be present in small quantities. The term syenite was originally applied to hornblende granite like that of Syene in Egypt, from which the name is derived. Syenite is not a common rock, some of the more important...
