Modern Benthic Foraminifera in the Surface Sediments of the Beaufort Shelf, Slope and Mackenzie Trough, Beaufort Sea, Canada: Taxonomy and Summary of Surficial Distributions

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

“…Figure 1 shows the locations of all the box core stations (foraminiferal data for surface studies by Scott et al [2008a, 2008c]) with the two piston core sites highlighted. Total numbers of individuals and percentages were determined for both the >63 μ m and the 45–63 μ m size fractions which show there were high abundances in both fractions but almost always different dominant species between them, illustrating once again why the small fractions must be examined, especially for some of the deep‐sea calcareous forms.…”

Calcareous microfossil-based orbital cyclostratigraphy in the Arctic Ocean

“…Studies of deglacial, Holocene and/or modern Arctic benthic foraminiferal faunas have been important in attributing dissolution to explain observed species distributions. These include studies of the Canadian Arctic (Scott et al, 2008 and references therein), Kara Sea (Hald and Steinsund, 1996;Polyak et al, 2002), Svalbard (Steinsund and Hald, 1994;Korsun and Hald, 2000), the Barents Sea (Korsun and Hald, 1998;Saher et al, 2012), Norwegian fjords (Alve et al, 2011), the St. Anna Trough (Hald et al, 1999), and the Canada Basin (Lagoe, 1977;Osterman et al, 1999). In comprehensive studies of eastern Arctic benthic foraminifers covering Arctic ridges and continental margins, Wollenburg and Mackensen (1998) and Wollenburg and Kuhnt (2000) concluded that seasonally sea-ice free regions experienced dissolution but that perennially sea-ice covered regions of the central Arctic had well-preserved benthic faunas.…”

Intra-annual Variability in Benthic Foraminiferal Abundance in Sediments of Disenchantment Bay, an Alaskan Glacial Fjord

“…The .63 mm size fraction was used in foraminiferal analysis in environments where water-mass movement and sedimentation is similar to DB (Jennings and Helgadottir, 1994). Jennings and Helgadottir (1994) and Scott et al (2008) concluded that including size fractions .63 mm and .45 mm, respectively, when picking foraminifera yields a more complete assemblage from sediments within tidewater fjords. We split fossiliferous samples with a microsplitter until one tray contained approximately 300 specimens.…”
