In a 2009 paper in Land Economics, Roy, Arnason and Schrank used a newly developed methodology based on cointegration analysis to establish and measure the role of the fishing industry as an economic base industry (and the only such base industry) for the Canadian province of Newfoundland over the period...
Since the collapse of the Newfoundland groundfishery in 1992, the snow crab fishery has become Newfoundland’s largest fishery, accounting for approximately half the value of total landings. This study uses trip log data to estimate the production frontier and the technical efficiency of this fishery using a Stochastic Frontier Analysis...
The basic hypothesis underlying this paper is that the amount of fishing that a fisher undertakes over a year is not determined solely by circumstances which are exogenous to the fisher, such as weather conditions and resource availability, but are the subject of individual choice. As such, the decision can...
Historically, the fishery has been the mainstay of the Newfoundland economy. Inevitably, its importance declined as
economic development proceeded, but was still quite substantial at the time of Confederation with Canada in 1949.
Since then, however, the census figures show a precipitous decline in the role of the fishery in...
Hyporheic Exchange Flow (HEF) is driven by head gradients defined by the hydro-topography of the stream surface, which is controlled by the particular geomorphology of the stream. We quantified the impact of large wood, which typically exerts a strong control on stream morphology, on HEF in a second order, low...

Numerous studies have explored how alluvial channel size and morphology are adjusted to different sediment and flow conditions, yet we still know very little about how and to what degree the flow regime controls channel form and processes. We use the term ‘channel form’ to refer to the size and...
We investigated the response of hyporheic exchange flow (HEF) to wood removal in a small, low-gradient, gravel bed stream in southeast Alaska using a series of groundwater models built to simulate HEF for the initial conditions immediately after wood removal and 1 month, 2 years, 4 years, and 16 years...
