“…R. obtusa has a life span of 3 years or less (Smith 1967) and declined in the Iqaluit region between the two time periods while N. pernula has a life span of 10 + years (Ansell et al 1978, Selin 2010) and this species slightly increased in abundance in the Cairn Island region between the two time periods. Therefore, natural cycles related to the lifespan of these common mollusc species could be responsible for the change in assemblages observed.…”

“…Life span information was available for only some of the common species in this study. For example, M. discors, T. gouldi, H. arctica, and N. minuta have a life span ranging from 3-10 years (Ansell et al 1978, Selin 2010, BIOTIC 2019) and these species declined in abundance in either the Iqaluit or Cairn Island regions between the two time periods.…”

Long-term studies provide an effective way to assess the ecological impacts of decades-long environmental change in Arctic coastal benthic environments but are undertaken rarely in the Canadian Arctic. In light of this, historical datasets can be compared with modern samples to examine temporal differences in benthic community structure. Frobisher Bay, Nunavut provides a unique opportunity to use a historical census to examine the impacts that long-term environmental change have had on the marine benthos. Between 1967-1976 and in 2016, infaunal samples were collected in inner Frobisher Bay and were compared to determine how the molluscan assemblages have changed between the two time periods. Molluscan assemblages in two regions of inner Frobisher Bay (Iqaluit and Cairn Island) were examined to minimize sampling discrepancies between the two time periods. A long-term increase in mean annual air temperature and a decline in the length of the ice cover season were observed. Both regions exhibited some change in sediment composition and quality and in molluscan assemblage between the two time periods and species diversity indices also indicated some change between time periods. Both the 1967-1976 and 2016 molluscan datasets provide a baseline for future long-term studies in a changing Arctic.

“…A suite of element-(Li, Mg, Mn, Sr, Mo, and Ba)-to-calcium ratios was examined at sub-annual resolution in shells of two bivalve species (S. groenlandicus and C. ciliatum). The specimens were deployed on oceanographic moorings for one year during September 2007-2008and September 2009-2010 whereas Rijpfjorden is a fjord with a sill (depth 100-200 m) that is influenced mainly by Arctic water masses (Svendsen et al, 2002;Howe et al, 2010;Wallace et al, 2010;Søreide et al, 2010). Kongsfjorden was ice-free throughout the field deployment with the exception of occasional drift ice, whereas Rijpfjorden was ice-covered for 8 months (January 21-September 16) in 2007-2008(Norwegian Meteorological Institute, 2014, and for 5 months in 2009-2010 (Vihtakari et al, 2016).…”

“…They are long-lived species, with maximum longevity of 30-60 years, forming aragonitic shells with prominent annual growth lines. These growth lines are deposited during a slow winter shell-growth period that is regulated by low food availability (Khim et al, 2003;Carroll et al, 2009;Sejr et al, 2009;Selin, 2010;Ambrose et al, 2012;Henkes et al, 2013;Vihtakari et al, 2016).…”

Understanding rapid climate change in the Arctic and its ecosystem implications requires more information on the environment at temporal resolutions and time-periods not available from instrumental records. Such information can be acquired through geochemical proxy records, but sub-annual records are rare. We analyzed shell material of bivalve mollusks (Serripes groenlandicus and Ciliatocardium ciliatum) placed on oceanographic moorings for one year in two Arctic fjords to assess the potential use of shell elemental ratios as environmental proxies.

“…However, their study was not guided by isotope sclerochronology and their methods for determining annual growth increments are unclear. Elsewhere, several other studies have shown much shorter maximum lifespans (8-10 years) from the Sea of Okhotsk and the Eastern Siberian Sea (Gagayev 1989;Selin 2007Selin , 2010. These studies though used ridges on the external shell surface instead of internal growth increments.…”

Age and growth of Astarte borealis (Bivalvia) from the southwestern Baltic Sea using secondary ion mass spectrometry

Traditional isotope sclerochronology employing isotope ratio mass spectrometry has been used for decades to determine the periodicity of growth increment formation in marine organisms with accretionary growth. Despite its well-demonstrated capabilities, it is not without limitation. The most significant of these being the volume of carbonate powder required for analysis with conventional drill-sampling techniques, which limit sampling to early in ontogeny when growth is fast or to species that reach relatively large sizes. In species like Astarte borealis (Schumacher, 1817), a common component of Arctic boreal seas, traditional methods of increment analysis are difficult, because the species is typically long-lived, slow growing, and forms extremely narrowly spaced growth increments. Here, we use Secondary Ion Mass Spectrometry (SIMS) to analyze δ 18 O in 10-μm-diameter spots and resolve the seasonal timing of growth increment formation in Astarte borealis in the southeastern Baltic Sea. In the individaul sampled here, dark growth increments can form in either the fall, winter, or spring. Furthermore, growth increment data from two populations (RFP3S = 54.7967° N, 12.38787° E; WA = 54.86775° N, 14.09832° E) indicate that in the Baltic Sea, A. borealis is moderately long-lived (at least 43 years) and slow growing (von Bertalanffy k values 0.08 and 0.06). Our results demonstrate the potential of A. borealis to be a recorder of Baltic Sea seasonality over the past century using both live-and dead-collected shells, and also the ability of SIMS analysis to broaden the spectrum of bivalves used in sclerocrhonological work.
