Foraminiferal assemblage changes over the last 15,000 years on the Mackenzie-Beaufort Sea Slope and Amundsen Gulf, Canada: Implications for past sea ice conditions
Scott, D. B. (David Bruce); Schell, Trecia; St-Onge, Guillaume; Rochon, Andre; Blasco, Steve (2009-06)Two cores, one from the Beaufort Sea Slope at 1000 m water depth (core 750) and one from the Amundsen Gulf at 426 m (core 124), were collected to help determine paleo-ice cover in the Holocene and late glacial of this area. ... -
Messinian deep-water turbidites and glacioeustatic sea-level changes in the North Atlantic: Linkage to the Mediterranean Salinity Crisis
Zhang, JJ; Scott, D. B. (David Bruce) (1996-06)Our benthic foraminiferal data clearly indicate eight layers of deepwater turbidites during the Messinian (MTL 1-8) and one in the early Pliocene (PTL 1) in Ocean Drilling Program Leg 105, Site 646B. These deep-water ... -
Paleo-sea ice conditions of the Amundsen Gulf, Canadian Arctic Archipelago: Implications from the foraminiferal record of the last 200 years
Schell, Trecia M.; Moss, Tamara J.; Scott, D. B. (David Bruce); Rochon, Andre (2008-03)Four boxcores were collected as part of the Canadian Arctic Exchange Shelf Study (CASES) in the Amundsen Gulf at water depths of 59 m to 600 m. Data from these cores help to develop a record of changes in the oceanographic ... -
Radiocarbon evidence for annual growth rings in the deep-sea octocoral Primnoa resedaeformis
Sherwood, OA; Scott, D. B. (David Bruce); Risk, MJ; Guilderson, TP (2005)The deep-sea gorgonian octocoral Primnoa resedaeformis is distributed throughout the Atlantic and Pacific Oceans at depths of 65 to 3200 m. It has a 2-part skeleton of calcite and gorgonin. Towards the inside of the axial ... -
Stable isotopic composition of deep-sea gorgonian corals Primnoa spp.: a new archive of surface processes
Sherwood, OA; Heikoop, JM; Scott, D. B. (David Bruce); Risk, MJ; Guilderson, TP; McKinney, RA (2005)The deep-sea gorgonian coral Primnoa spp. live in the Atlantic and Pacific Oceans at depths of 65 to 3200 m. They have an arborescent growth form with a skeletal axis composed of annual rings made from calcite and gorgonin. ...
