Radiocarbon (Δ14C) and Stable Carbon (δ13C) Isotopic Composition of Dissolved Inorganic Carbon (DIC) in Baffin Bay
… anthropogenic carbon below the mixed layer. Baffin Bay is a semi-enclosed, Arctic basin that supplies cold surface water to the Labrador Sea; a critical region for North Atlantic deep-water formation. While the physical oceanography of surface Baffin Bay is well characterized, less is known …

Increased Shipping Activity and Marine Mammals in Baffin Bay and Davis Strait: Developing a Low-Impact Shipping Corridor.
… other negative impacts. The Canadian waters of Baffin Bay and Davis Strait are experiencing this increased vessel traffic as part of the Northwest Passage. Managing these worsening impacts is of the utmost importance to preserve the sensitive ecosystem of the Canadian Arctic. This thesis …

Distribution of Dehalococcoidia in marine sediments and strategies for their enrichment
… were investigated in sediments of the Arctic Baffin Bay. Geochemical studies showed the shelf as an area rich in organic matter, with indications for the presence of sulphate reduction (highest dsrA gene copies and a decrease in sulphate concentration in its pore-waters). On the other hand, …

Biogenic silica dynamics of Arctic marine ecosystems
… the Canadian Arctic Archipelago (CAA), through Baffin Bay and into the Labrador Sea. We show that diatoms are both abundant and productive throughout these regions in summer, despite widespread Si limitation in the low-nutrient surface waters. Finally, we also investigated the natural variations …

Relationships between wintertime modes of atmospheric variability on intermediate and long timescales
… variability in a region extending from Baffin Bay to Scandinavia. In the Pacific sector, the negative polarity of a PNA-like pattern is associated with an enhancement of intermediate-timescale variance for a region centered over Alaska and extending over the North Pacific. Similar …

Arctic Aerosol Sources and Continental Organic Aerosol Hygroscopicity
… aerosol. Small particles were observed in Baffin Bay during September 2008 that coincided with high atmospheric and ocean surface dimethyl sulphide (DMS) concentrations suggesting that the aerosol formed from oceanic sources. An aerosol microphysics box model confirmed that local DMS could …

State estimation of the Labrador Sea with a coupled sea ice-ocean adjoint model
… the ocean and sea ice state in Labrador Sea and Baffin Bay is constructed and analyzed. The estimate is a synthesis of a regional coupled 32 km ocean and sea ice model with a suite of contemporary in situ and satellite hydrographic and SI data. The synthesis of SI data is made possible with the …

Structural, stratigraphic and geochemical studies of the Horwood Peninsula - Gander Bay Area, Northeast Newfoundland /
The Horwood Peninsula - Gander Bay area is located at NE Newfoundland in the Botwood Zone (Williams et a1., 1974) or in the Dunnage Zone (Williams, 1979) of the Central Mobile Belt of the Newfoundland Appalachians. The area is underlain by Middle Ordovician to possible Lower Silurian rocks of the …

Cenozoic deep-water agglutinated foraminifera in the North Atlantic
… for Trinidad, Northern Spain, the Labrador Sea, Baffin Bay, and the Norwegian-Greenland Sea. These schemes are compared with existing biostratigraphic frameworks from the Labrador Margin, the North Sea, and the Polish Carpathians. A number of species show utility for biostratigraphy in the North …
