In coastal regions, age-0 juveniles of many fish species are capable of recruiting to either marine or estuarine nursery habitats, yet the ecological consequences for cohorts that use marine versus estuarine nurseries is poorly understood. In the present study, stable isotope (δ13C, δ15N) and stomach contents data were used to compare trophic ecology associated with differential habitat use for...

[1] In summer on the shallow New England continental shelf, near the coast the water temperature is much cooler than the observed surface heat flux suggests. Using depth‐integrated heat budgets in 12 and 27 m water depth calculated from observed surface heat flux, water temperature, and velocity, we demonstrate that on time scales of weeks to months the water is persistently cooled due to a mea...

The Greenland ice sheet (GrIS) advanced onto the continental shelf during the last glacial period. While deglacial records for when the GrIS withdrew onto the modern coastline are relatively abundant, the timing of early GrIS retreat on the shelf is poorly constrained. Here we use planktic foraminiferal d18O, sediment grain size, sedimentation rates, and 14C ages in southeastern Davis Strait co...

The coastal ocean may experience periods of fluctuating along-shelf wind direction, causing shifts between upwelling and downwelling conditions with responses that are not symmetric. We seek to understand these asymmetries and their implications on the Eulerian and Lagrangian flows. We use a two-dimensional (variations across-shelf and with depth; uniformity along-shelf) primitive equation nume...

Precise knowledge about the extent of the West Antarctic Ice Sheet (WAIS) at the Last Glacial Maximum (LGM; c. 26.5-19 cal. ka BP) is important in order to 1) improve paleo-ice sheet reconstructions, 2) provide a robust empirical framework for calibrating paleo-ice sheet models, and 3) locate potential shelf refugia for Antarctic benthos during the last glacial period. However, reliable reconst...

one of the most important problems of fish is the short shelf lifebecause of the high unsaturated fatty acids. so, with the help of antioxidant compounds can be increased shelf life of fish. the aim of this study was to investigate the effect of vitamin e as a natural antioxidant to increase shelf life of rainbow trout fillet during storage at refrigerator temperature (4±1 0c). treatments were ...

colour is one of the most important quality factors that can influence and determine the shelf life of canned chicken kebab. colour change is considered as unsuitable distasteful to consumers, indicating the end of a product's shelf life. in this study quality aspects of samples were examined over one month intervals after being prepared and while being stored under accelerated (44 °c) con...
