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, David B., Trecia Schell, Guillaume St-Onge, Andre Rochon, et al. 2009. "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." Paleoceanography 24: 2219-PA2219. doi:10.1029/2007PA001575Two 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, and DB Scott. 1996. "Messinian deep-water turbidites and glacioeustatic sea-level changes in the North Atlantic: Linkage to the Mediterranean Salinity Crisis." Paleoceanography 11(3): 277-297. doi:10.1029/96PA00572Our 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., Tamara J. Moss, David B. Scott, and Andre Rochon. 2008. "Paleo-sea ice conditions of the Amundsen Gulf, Canadian Arctic Archipelago: Implications from the foraminiferal record of the last 200 years." Journal of Geophysical Research-Oceans 113(C3): 0302-C03S02. DOI:10.1029/2007JC004202Four 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, DB Scott, MJ Risk, and TP Guilderson. 2005. "Radiocarbon evidence for annual growth rings in the deep-sea octocoral Primnoa resedaeformis." Marine Ecology Progress Series 301: 129-134. doi:10.3354/meps301129The 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, JM Heikoop, DB Scott, MJ Risk, et al. 2005. "Stable isotopic composition of deep-sea gorgonian corals Primnoa spp.: a new archive of surface processes." Marine Ecology Progress Series 301: 135-148. doi:10.3354/meps301135The 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. ...
