THE Greenland Sea is particularly important to the world ocean circulation, and potentially to carbon dioxide exchange between the ocean and atmosphere, because it is an area of surface convergence and deep-water formation1–3. Previous investigations in

“It comes as no surprise that the slow production of scientific knowledge by an ever-growing international and interdisciplinary community of climate change researchers is not feasible to track the accelerating pace of cultural, political and economic perceptions of, and actions to the many th...
AWARENESS ASPECTS ON IMPORTANCE OF FOREST ECOSYSTEMS AND CLIMATE CHANGE IMPACTS ON IT- A STUDYPast several decades, increasing human activity has rapidly polluted and destroyed many ecological habitats throughout the world almost every way imaginable. The man disrupted the food chain, the carbon cycle...
the circulatory system is a vast network of organs and blood vessels that functions both by transporting the necessities (nutrients, oxygen and hormones) and removal of wastes (carbon dioxide, ammonia, urea and other nitrogenous wastes) from the different parts of the body. not only does the ...
(RPA), which was established in 1985 as a formal act. In the early 2010s, a similar intervention was proposed in the context of the “Rethink Athens” action. Once again Panepistimiou Street was envisioned as a place where people walk, cycle and enjoy more actively the urban landscape. ...
This strain formed globosa-type colonies (Jahnke 1989).Phaeocystis was grown in 1 1 serum bottles incubated on a rolling device at 10 "C and a light intensity of 40 pE m-' S-' in a 14:10 L : D cycle. The artificial seawater medium described by Veldhuis & Admiraal (1987) was used...
A measuring cycle, including two blanks and measurement of the concentration of ionic gases, took 2 h. The performance of the MARGA-sizer was checked prior and after the summer campaign. It was noticed after the campaign that a fraction (about 7%) of the particles with a size larger than ...
The Central Hardwood Forest (CHF) covers a large portion of the eastern United States and is one of the largest forested biomes in the world1. The CHF is currently a major carbon sink (i.e. positive net change of carbon den- sity), similar to many other major temperate forests in the...
