Genetic differentiation among Atlantic cod (Gadus morhua) from Browns Bank, Georges Bank, and Nantucket Shoals
The Atlantic cod (Gadus morhua) is a migratory gadid found on both sides of the North Atlantic. In the Northwest Atlantic, cod are distributed nearly continuously along the continental shelf from Greenland to North Carolina, spawning in relatively discrete, temporally stable areas, and different regions are regarded as different management units defined primarily by latitude and bathymetry (Ruz...
متن کاملThe front on the Northern Flank of Georges Bank in spring: 1. Tidal and subtidal variability
[1] During March–April 1999, 2 weeks of undulating CTD and shipboard acoustic Doppler current profiler surveys revealed the variability of the intense internal tide on the northern edge of Georges Bank. The nature of the internal tide was modulated by episodic surface intrusions of cool, fresh Scotian Shelf Water (SSW), stratifying the otherwise vertically well-mixed outer bank. The introductio...
متن کاملNonlinear dynamic features and co-predictability of the Georges Bank fish community
We examined evidence for nonlinear dynamics in fishery-independent survey data for an assemblage of 26 fish species on Georges Bank spanning the period 1963 to 2008. We used nonlinear time series analysis to determine (1) the presence of nonlinear dynamics in fish populations on Georges Bank, (2) the minimum number of dimensions required to effectively describe system dynamics, (3) the strength...
متن کاملGeospatial analysis of habitat use in yellowtail flounder Limanda ferruginea on Georges Bank
Three theories of habitat use proposed for marine fishes — the constant density model, the proportional density model, and the basin model — make contrasting predictions of how the geographical range, local density, and fitness change as population size changes. We tested model predictions with survey data on yellowtail flounder Limanda ferruginea from the Georges Bank region, where abundance c...
متن کاملRelationship of predation potential to mortality of Calanus finmarchicus on Georges Bank, northwest Atlantic
Based on 29 cruises on Georges Bank between January and June, conducted as part of the U.S. Global Ocean Ecosystem Dynamics program, we describe seasonal and spatial variability of early life history mortality for the planktonic copepod Calanus finmarchicus and relate mortality to an index of predation potential from a suite of suspension-feeding predators. Emphasis is placed on the earliest li...
