A substantial increase in the number of studies using the optical properties (absorbance and fluorescence) of dissolved organic matter (DOM) as a proxy for its chemical properties in estuaries and the coastal and open ocean has occurred during the last decade. We are making progress on finding the actual chemical compounds or phenomena responsible for DOM’s optical properties. Ultrahigh resolution mass spectrometry, in particular, has made important progress in making the key connections between optics and chemistry. But serious questions remain and the last major special issue on DOM optics and chemistry occurred nearly 10 years ago. Controversies remain from the non-specific optical properties of DOM that are not linked to discrete sources, and sometimes provide conflicting information. The use of optics, which is relatively easier to employ in synoptic and high resolution sampling to determine chemistry, is a critical connection to make and can lead to major advances in our understanding of organic matter cycling in all aquatic ecosystems. The contentions and controversies raised by our poor understanding of the linkages between optics and chemistry of DOM are bottlenecks that need to be addressed and overcome.

High-Arctic Ecosystem Dynamics in a Changing Climate is based on data collected during the past 10 years by Zackenberg Ecological Research Operations (ZERO) at Zackenberg Research Station in Northeast Greenland. This volume covers the function of Arctic ecosystems based on the most comprehensive long-term data set in the world from a well-defined Arctic ecosystem. Editors offer a comprehensive and authoritative analysis of how climate variability is influencing an Arctic ecosystem and how the Arctic ecosystems have inherent feedback mechanisms interacting with climate variability or change. The latest research on the functioning of Arctic ecosystems Supplements current books on arctic climate impact assessment as a case study for ecological specialists Discusses the complex perpetuating effects on Earth Vital information on modeling ecosystem responses to understand future climates

An exploration of the political significance of the Arctic's vast untapped wealth of natural resources, and a gripping account of the race to exploit them On August 2, 2007, a Russian submarine captured world headlines by making a dangerous journey to the bottom of the Arctic seabed and planting a metal, rustfree national flag more than 14,000 feet beneath the North Pole. The aim was to assert Russia's legal sovereignty over a region whose importance had only recently started to become apparent as its melting ice had made, or was expected to make, vast natural resources open to exploitation. The latest estimates are that the region holds around 13% of the world's undiscovered oil and as much as 30% of undiscovered natural gas reserves that would be hugely profitable for any country that managed to secure control over them. Gold, platinum, copper, and other precious metals have also been found along the coast. Neighboring countries - Russia, the United States, Canada, Denmark, and Norway - are already doing everything they can to mark out new borders. The ensuing political disagreements over the issue are already rife. In particular, games of political intrigue between Moscow and Washington are being played out in the region. But as the world's resources become increasingly scarce and valuable, could the scramble for Arctic resources become violent? Could a "War for the Arctic" be fought? Praise for The Oil Hunters: "The Dramatic Days of oil exploration in the first half of the 20th century are narrated in gripping fashion by Roger Howard." -The Spectator "A fascinating story for anyone interested in one of today's main economic problems: How to reduce the hundreds of billions that Americans spend every year to import oil...the book is packed with intrepid geologists, risk-averse business people, hardup Mideast rulers and ingenious promoters- all concerned with driving up profits."-The Associated Press
