A winter city is any urban centre that experiences a long, dark, cold, and/or snowy winter. The Winter Cities movement is a more precise concept, referring to cities taking an active role in becoming more appealing and functional in winter, primarily through physical interventions. The movement...
Age, origin, and thermal evolution of the ultra-fresh ~1.9 Ga Winnipegosis Komatiites, Manitoba, CanadaDownload
The Proterozoic spans the longest portion of earth's history, yet in contrast to the Archaean, the record of komatiites and related high MgO igneous rocks from this Eon is sparse. This paper describes the pristine Palaeoproterozoic Winnipegosis Komatiites, from Manitoba, Canada, which form part...
Horizontal advection has been assumed negligible within the Alaskan Gyre (AG). With the recently available Argo data this assumption can be tested. To estimate advection, the observed heat content (estimated from Argo data) was compared to the expected (based on surface heat fluxes) and the...
Mixed layer depth (MLD) is computed, based upon historical measurements along Line P, in the Gulf of Alaska. Forty-six years of data are used for the monthly climatological calculations. To examine variability, the data are divided into two periods, pre and post 1976. Mixed layers deepen in...
Paleontology is a multi-faceted subject that involves taxonomy and community analysis as two of its cornerstones. Both qualitative and quantitative approaches have been incorporated into the various methods employed in such analyses. Each paleontologist obvious has his or her own preference that...
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...
Carbon and nitrogen isotope systematics in diamond: Different sensitivities to isotopic fractionation or a decoupled origin?Download
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...
Carbon management in New Zealand local government: Co-benefits of action and organizational resolve in the absence of government supportDownload
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...
Cave-fills in Miocene-Pliocene strata on Cayman Brac, British West Indies: Implications for the geological evolution of an isolated oceanic island.Download
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...
