Warming Oceans Will Play Major Role In Less Phytoplankton Diversity
2012-10-26 07:33:14

Lawrence LeBlond for redOrbit.com - Your Universe Online Phytoplankton (plant wanderers), organisms that exist in the sunlit layer of the world´s oceans, are important for the sustainability of the aquatic food web. However, future warming oceans could significantly alter the populations of these important organisms, further impacting climate change. Since phytoplankton play a major role in the food chain and the world´s carbon, nitrogen and phosphorous cycles, a significant...

Ocean Acoustics Changing
2012-10-19 14:07:43

Brett Smith for redOrbit.com - Your Universe Online Along with negatively impacting marine life and global climate change, the acidification of the Earth´s oceans could have the unintended side effect of changing the acoustics beneath the water´s surface. New research suggests that a future, more acidic ocean would resemble the one that existed around 110 million years ago, when dinosaurs still roamed both the land and sea. Climatologists have been raising concerns in recent...

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...
