Abstract Boron is a quintessential crustal element but its conspicuous presence in diamond – a mantle mineral – raises questions about potential subduction pathways for boron and other volatiles. It has been a long-standing goal to characterize the isotopic composition of boron in blue,...

The fact that Canadian Arctic ice is melting is not in contention-it's the rate at which ice is melting and what melting ice means for the future of the Northwest Passage that ignite controversy. According to Huebert (2003). data from satellite imagery suggest that the rate of melt in the...

Using stable isotope data obtained on multiple aliquots of diamonds from worldwide sources, it has been argued that carbon and nitrogen in diamond are decoupled. Here we re-investigate the carbon–nitrogen relationship based on the most comprehensive microbeam data set to date of stable isotopes...

In an effort to promote public sector carbon management, in 2004, New Zealand’s (NZ) Labour-led government funded local government membership in the Communities for Climate Protection - New Zealand (CCP-NZ) program, the NZ arm of ICLEI’s Cities for Climate Protection campaign. In late 2008 the...

Cascading of dense water from the shelf to deeper layers of the adjacent ocean basin has been observed in several locations around the world. The West Greenland Shelf (WGS), however, is a region where this process has never been documented. In this study, we use a numerical model with a 1/48...

An 8-m-high wall in a quarry on the west end of Cayman Brac exposes the upper part of the Cayman Formation (Miocene), the lower part of the overlying Pedro Castle Formation (Pliocene), and the Cayman Unconformity, which is a karstic unconformity that separates these formations. The modern-day...

Southward transports in the deep western boundary current across 53°N, over 1949–99, are determined from a historical reconstruction. Long-term mean transports, for given water masses, for net southward transport (the southward component of the transport not including recirculation given in...

The pan-Arctic domain is undergoing some of Earth's most rapid and significant changes resulting from anthropogenic and climate-induced alteration of freshwater distribution. Changes in terrestrial freshwater discharge entering the Arctic Basin from pan-Arctic watersheds significantly impact...

Deep convection and associated deep water formation are key processes for climate variability, since they impact the oceanic uptake of heat and trace gases and alter the structure and strength of the global overturning circulation. For long, deep convection in the subpolar North Atlantic was...

Surrey, British Columbia, stands out in its efforts to go beyond the provincial mandate on climate change mitigation and incorporate adaptation into strategic planning. The community is not currently overwhelmed by climate change impacts, and has local agents and institutions in place to...
