Linkages Between East China Sea Deep‐Sea Oxygenation and Variability in the East Asian Summer Monsoon and Kuroshio Current Over the Last 400,000 years

“…Epistominella exigua is a cosmopolitan species feeding opportunistically on phytodetritus deposited seasonally on the seafloor and can tolerate a varying organic export flux (Das et al., 2021; Gooday, 1988; R. K. Singh & Gupta, 2004, 2010). Cassidulina laevigata , is a shallow infaunal taxon (Fontanier et al., 2002), typifying relatively cold waters with high organic matter content (Pascual et al., 2020), and is tolerant of moderate oxygen depletion in the bottom and pore water under high organic flux rates (Das et al., 2021; Nardelli et al., 2014; Sen Gupta & Machain‐Castillo, 1993). Bolivina robusta is an open ocean infaunal species found in temperate to the subtropical middle to upper bathyal depths (Haller et al., 2018; B. Zhao et al., 2018).…”

Intermediate ocean circulation and cryosphere dynamics in the northeast Atlantic during Heinrich Stadials: benthic foraminiferal assemblage response

“…We therefore assume that the C. crassa – E. excavatum f. clavatum association in our record is coherent with near‐glacier environments. This is further corroborated by the absence of these species from the upper slope glacial record PP10‐12 from the southeast BoB (Pascual et al ., 2020), far from both the ice‐sheet extent limit and the Channel River mouth. Based on the above, we summed the percentages of E. excavatum f. clavatum and C. crassa to constitute the group of glacier‐proximal indicator species.…”

Deep-water paleoenvironmental changes based on early-middle Miocene benthic foraminifera from Malta Island (Central Mediterranean)

“…Species abundant in poor oxygen, rich in organic matter with elevated productivity environments (Alavi, 1988;Martin et al, 2007;Singh et al, 2015;Pascual et al, 2020). Species behaving as opportunistic when a great amount of organic matter is available, and usually associated to upwelling phenomena (Okada, 1983;Mathieu, 1986;Guerreiro et al, 2009).…”

“…Species behaving as opportunistic when a great amount of organic matter is available, and usually associated to upwelling phenomena (Okada, 1983;Mathieu, 1986;Guerreiro et al, 2009). Species indicating dysoxia (Kaiho, 1994;Pascual et al, 2020).…”

“…Opportunistic species adapted to high food concentration (Baas et al, 1998;Pascual et al, 2020), related to high flux of organic carbon (Jorissen et al, 2007;Singh et al, 2015;Pascual et al, 2020). Suboxic species ( Kaiho, 1994), related with upwelling currents (Levy et al, 1995;Pascual et al, 2020).…”
