Reducing the risk of lethal encounters: vessels and right whales in the Bay of Fundy and on the Scotian Shelf
The North Atlantic right whale Eubalaena glacialis is endangered, in part, due to vessel-strike mortality. We use vessel traffic and right whale survey data (similar to 3 nautical miles [n miles], similar to 5.6 km resolution) ...
Demise of the garden of Acadia
(DVL Publishing Inc., Liverpool, Nova Scotia, 1981-07)
In the late 1970s, plans were being developed for construction of a tidal power barrage at the mouth of the Annapolis River. Much of the land by the river in that area was dyked and was used by farmers for grazing and ...
Investigations into the nucleophilic meso-substitution of F-BODIPYs and improvements to the synthesis of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene.
A series of three F-BODIPYs, with varying levels of steric crowding about the meso-position were selected to investigate nucleophilic meso-substitution of F-BODIPYs. The synthesis of one of these F-BODIPYs, 4,4-difluor ...
Heteroleptic zinc dipyrromethene complexes
H-1 NMR spectroscopy has been used to study the complexation of a per-alkyl dipyrromethene with zinc acetate. An intermediate, assigned to be the heteroleptic Zn(dipyrromethene) (acetate) complex, is observed under titration ...
Incorporating concerns of coastal communities in planning and management: The case study of Port Joli and lessons learned from the Eastport Marine Protected Areas
Marine environment and resources are experiencing the degradation in Canada. Since Oceans Act was established in 1996, the Fisheries and Oceans Canada (DFO) has tried to engage a broader view of participatory governance. ...
Isolation and characterization of a novel tetrahydro-[2,2 ']bipyrrolyl dimer as an impurity from a Knorr reaction
A novel dimer, tetraethyl 2,2',3,3'-tetramethyl-1,1',2,2'-tetrahydro-4H,4'H-2,2'-bipyrrolyi-5,5,5',5'-tetracarboxylate, has been isolated as an impurity (0.4% yield) from a Knorr reaction for the synthesis of ...
Field Trip B9: Gold metallogeny in the Newfoundland Appalachians
(Atlantic Geoscience Society, 2005)
A Proposed Arctic Search and Rescue Strategy for Canada
The Canadian Arctic has experienced a notable increase in maritime activity in recent years, driven in part by increased accessibility due to environmental changes as well as a growing northern cruise industry and hydrocarbon ...
Why an ecosystem approach is the wrong paradigm for the next stage of fisheries management
Scientists from the Department of Fisheries and Oceans (DFO) manage groundfish stocks by collecting biomass measurements that are used to provide scientific advice on catch limits. Clearly, if the data is uncertain or ...
Probability and mitigation of vessel encounters with North Atlantic right whales
(Inter-Research, Nordbuente 23 Oldendorf/Luhe 21385 Germany, 2009-03)
Successful mitigation of vessel-whale encounters requires quantitative estimates of vessel strikes, how strike rates change over time, where strikes are most likely to occur, and options for minimizing strikes. In addressing ...
