“…In present-day environments, numerous studies have determined morphogroup trends in a wide variety of settings, including marsh, neritic, bathyal, abyssal, high-latitude fjords, and tropical bays (Jones and Charnock 1985; Jorissen 1999; Nigam et al 2000; Violanti 2000; Kaminski and Gradstein 2005; Alperin et al 2011; Murray et al 2011; Manasa et al 2016; Saalim et al 2018; Saraswat et al 2018; Verma et al 2018). In the geological record, morphogroups have been analyzed from the Devonian (Holcová and Savik 2013), Jurassic (Nagy 1992; Monaco et al 1994; Reolid et al 2008; Reolid et al 2010; Reolid et al 2012; Nikitenko et al 2013; Rita et al 2016; Reolid et al 2019), Cretaceous (Koutsoukos and Hart 1990; Cetean et al 2011; Setoyama et al 2013; Turkistani et al 2022), Cretaceous–Tertiary (Peryt et al 1997; van den Akker et al 2000), and Eocene (Bindiu and Filipescu 2015).…”

“…Although not a precise paleoenvironmental tool, this approach has been used with some minor variations in numerous paleontological studies to characterize biofacies, depositional environments, and species habit preference, among others.

This study assesses the foraminiferal morphogroup concept as a quantitative tool for interpreting environments of deposition in the geological record. This was achieved by first establishing a solid paleoenvironmental framework based on assessment of trace fossils (Zoophycos, Cruziana, and Phycosiphon ichnofacies, and the unnamed brackish-water association), sedimentology, and facies analysis of shallow-marine siliciclastic units of the upper Albian Viking Formation of the Western Interior Seaway, Canada. Foraminiferal morphogroups were integrated into a framework of six well-defined marine mudstone-dominated facies—estuarine, embayment, prodelta, upper offshore, lower offshore, and marine shelf. Seven morphogroups were recognized, quantified, and labeled using alphanumeric codes—A (tubular), B1 (globular), B2 (coiled, flat), B3 (lenticular), C1 (elongate), C2 (quinqueloculine), and D (trochospiral). Tubular forms (A, Bathysiphon) occur rarely in these shallow-marine facies. Globular forms (B1, Lagenammina) are common in estuarine (33%) and embayment (23%) facies, but also occur elsewhere in low numbers (7–14%). Coiled planar forms (B2, Ammodiscus) occur only rarely (1–8%), but have a minor presence in embayment facies (8%). Lenticular forms (B3, Haplophragmoides) are dominant in estuarine facies (43%) and occur commonly in other environments (9–29%) as well. Elongate forms (C1, Ammobaculites, Reophax, Verneuilinoides) dominate all shallow-marine facies (43–80%), except estuarine (10%). Quinqueloculine forms (C2, Miliammina) have a minor presence in prodelta and marine facies (5%) but are generally rare. Trochoid forms (D, Trochammina) occur rarely, but are relatively common in the prodeltaic facies (15%). Albian foraminiferal morphogroups of the Viking Formation are comparable to those of modern-day offshore environments from water depths of 13 to 160 meters. Foraminiferal morphogroups are objective entities independent of taxonomic determinations. Analysis of their form and function is applicable not only in the shallow-marine facies of the Albian Western Interior Seaway, but in similar facies throughout the geologic record.

“…This result goes well with the study that has shown that the calving rate of the Kongsbreen glacier has increased in addition to increasing meltwater discharge during the melt season of 2016 (Schild et al, 2018). The abundance of agglutinated foraminifera in the proximal part has been attributed to meltwater flux and sediment load (Saraswat et al, 2018). Spiroplectammina biformis and Textularia spp.…”

Benthic foraminifera assemblages from two fjords of Svalbard—Kongsfjorden and Krossfjorden in the High Arctic—have been studied. The foraminifera assemblages show three characteristic assemblages from the two fjords’ glacial proximal, middle and distal parts. The Cassidulina reniforme– Elphidium clavatum, Textularia spp. assemblage dominates the foraminifera fauna near the glacier proximal that indicates increased sedimentation and meltwater runoff; a Nonionellina labradorica– Islandiella helenae– Lobatula lobatula assemblage relates to well-oxygenated and high energy conditions and mainly occupies the middle part; and the Nonionellina labradorica– Islandiella helenae assemblages dominate in the distal region that indicates high surface primary productivity. Krossfjorden contains an oxygen deficiency zone around the middle part characterised by Stainforthia loeblichi. The abundance of Islandiella helenae and Nonionellina labradorica indicates that the high surface primary productivity of Krossfjorden is more than that of Kongsfjorden.

Stable isotopic signatures of sediment carbon and nitrogen sources and its relation to benthic meiofaunal distribution in the Arctic Kongsfjord

et al. 2021

The interest of benthologists in meiofaunal organisms begin in the early 1980s (Giere, 2009). Meiofauna groups are characterized by tiny size with short generation time and continuous reproduction (Higgins & Thiel, 1988;Ingole et al., 2000). As they are very difficult to isolate from the sediment due to their small size, the lack of taxonomic materials for identification leads to neglecting this important invertebrate group from previous benthic studies
