“…7 Spectral analysis for 142-years-old shell SF1 using MTM (top) and SSA (bottom) using KSpectra (version 2.2) is shown. The black dashed contour (top) and the black vertical bars (bottom) are the 5% significance levels, using a red-noise (autoregressive lag1) background spectrum primary production and sedimentation rates (Witbaard et al 1997), because A. islandica is an active suspension feeder in the benthic zone primarily relying on phytoplankton supply (Cargnelli et al 1999). The strong positive relationship between the relative abundance of zooplankton C. finmarchicus and shell growth (r 2 = 0.55; p \ 0.0001) suggests that it is appropriate to use SGIs from A. islandica to reconstruct at least one major component of productivity in the western Gulf of Maine.…”

To investigate environmental variability during the late Holocene in the western Gulf of Maine, USA, we collected a 142-year-old living bivalve (Arctica islandica) in 2004, and three fossil A. islandica shells of the Medieval Warm Period (MWP) and late MWP / Little Ice Age (LIA) period (corrected 14 C AMS = 1030 ± 78 AD; 1320 ± 45 AD; 1357 ± 40 AD) in 1996. We compared the growth record of the modern shell with continuous plankton recorder (CPR) time-series from the Gulf of Maine. A significant correlation (r 2 = 0.55; p \ 0.0001) exists between the standardized annual growth index (SGI) of the modern shell and the relative abundance of zooplankton species Calanus finmarchicus. We therefore propose that SGI data from A. islandica is a valid proxy for paleo-productivity of at least one major zooplankton taxa. SGIs from these shells reveal significant periods of 2-6 years (NAO-like) based on wavelet analysis, multitaper method (MTM) analysis and singular spectrum analysis (SSA) during the late Holocene. Based on established physical oceanographic observation in the Gulf of Maine, we suggest that slope water variability coupled with North Atlantic Oscillation (NAO) dynamics is primarily responsible for the observed SGI variability.

“…The SSTs are analyzed for the summer period (June-August) and for the NA region between 60 • W-30 • E and 40-75 • N motivated by the growing season of Arctica islandica (Schöne et al, 2004(Schöne et al, , 2005. The pseudo-proxy sample sites are based on five real-world proxy sites of Arctica islandica, including collection sites in the North Sea (NS: 1 • E, 58.5 • N; Witbaard et al, 1997), the Irish Sea (IrS: 5 • W, 52.5 • N; Butler et al, 2009), the coast of Scotland (Sct: 7 • W, 56.5 • N; Reynolds et al, 2013), the North Icelandic shelf (IS: 20 • W, 66.5 • N; Butler et al, 2013), and a location on the island of Ingøya (InI: 24 • E, 71.5 • N; Mette et al, 2015).…”

Abstract. Two statistical methods are tested to reconstruct the interannual variations in past sea surface temperatures (SSTs) of the North Atlantic (NA) Ocean over the past millennium based on annually resolved and absolutely dated marine proxy records of the bivalve mollusk Arctica islandica. The methods are tested in a pseudo-proxy experiment (PPE) setup using state-of-the-art climate models (CMIP5 Earth system models) and reanalysis data from the COBE2 SST data set. The methods were applied in the virtual reality provided by global climate simulations and reanalysis data to reconstruct the past NA SSTs using pseudo-proxy records that mimic the statistical characteristics and network of Arctica islandica. The multivariate linear regression methods evaluated here are principal component regression and canonical correlation analysis. Differences in the skill of the climate field reconstruction (CFR) are assessed according to different calibration periods and different proxy locations within the NA basin. The choice of the climate model used as a surrogate reality in the PPE has a more profound effect on the CFR skill than the calibration period and the statistical reconstruction method. The differences between the two methods are clearer for the MPI-ESM model due to its higher spatial resolution in the NA basin. The pseudo-proxy results of the CCSM4 model are closer to the pseudo-proxy results based on the reanalysis data set COBE2. Conducting PPEs using noise-contaminated pseudo-proxies instead of noisefree pseudo-proxies is important for the evaluation of the methods, as more spatial differences in the reconstruction skill are revealed. Both methods are appropriate for the reconstruction of the temporal evolution of the NA SSTs, even though they lead to a great loss of variance away from the proxy sites. Under reasonable assumptions about the characteristics of the non-climate noise in the proxy records, our results show that the marine network of Arctica islandica can be used to skillfully reconstruct the spatial patterns of SSTs at the eastern NA basin.

“…Growth tren& ofall these chronologies correlate well with either water temperatures (observed or derived from 518Oshal) or a combination of water temperature and salinity. Furthermore, Arctica islandica master chronologies by WITBAARD (1996) and WITBAARD et al (1997) indicate hydrography-related growth patterns in North Sea specimens.…”

The cornucopia of chilly winters: Ocean quahog (Arctica islandica L., Mollusca) master chronology reveals bottom water nutrient enrichment during colder winters (North Sea). -Senckenbergiana marit., 32 (1/2): 165-175, 6 figs., 1 tab.; Frankfurt a.M.]We studied variations in annual shell growth rates of ten live-collected Arctica islandica specimens from three localities at the Dogger Bank in the central North Sea. Synchronous growth curves from contemporaneous specimens enabled the construction of a 65-year multi-locality master chronology.Stepwise multiple linear correlation analysis indicated a highly significant (p < 0.01) negative relationship between annual shell growth and winter sea surface temperatures (SST) during the period of 1953 to 1995. Up to 27.5% of the variation in the annual shell growth is explained by winter temperature. We explain the higher growth levels in colder winters by higher food supply. During warmer winters both the stratification and bottom water currents in the study area seem to be stronger and prevent downwardmixing of nutrients as well as settlement of food on the sea floor. During colder winters, however, the stratification weakens and phytoplankton produced in the cold surface layer reaches the sea floor. Longterm changes in shell growth rates are thus directly connected to hydrographic changes in the North Sea, which in turn are related to fluctuations of the North Atlantic Oscillation (NAO).Our study demonstrates the usefulness of Arctica islandica for long-term, high-resolution environmental reconstructions and contributes to further understanding natural and anthropogenic variability in the environmental history of the North Sea.
