“…The appearance of the thermophilous mussel Mytilus edulis at the outer part of Woodfjorden (Reinsdyrflya) supports the assumption of a surface injection of AW at least from ∼ 10.6 ka on (9815 ± 80 14 C a; Salvigsen, 2002). Several studies around Spitsbergen report about a benthic faunal pattern comparable to the record above during the HTM (Groot et al, 2014;Rasmussen et al, 2012;Skirbekk et al, 2010;Ślubowska-Woldengen et al, 2007). Ślubowska-Woldengen et al (2008) showed that N. labradorica reached maximum percentages at sites influenced by the WSC or the Svalbard Branch.…”

“…In contrast to conditions inferred above, some other studies state a general warming trend (Bonnet et al, 2010;D'Andrea et al, 2012;Jernas et al, 2013;Majewski et al, 2009;Spielhagen et al, 2011;Werner et al, 2011) as well as a strengthened influx of AW during the last 2 millennia in the Svalbard area (Groot et al, 2014;Rasmussen et al, 2012;Sarnthein et al, 2003;Ślubowska et al, 2005). However, as the midHolocene is missing in the present record (see Sect.…”

Abstract. Atlantic Water (AW) advection plays an important role in climatic, oceanographic and environmental conditions in the eastern Arctic. Situated along the only deep connection between the Atlantic and the Arctic oceans, the Svalbard Archipelago is an ideal location to reconstruct the past AW advection history and document its linkage with local glacier dynamics, as illustrated in the present study of a 275 cm long sedimentary record from Woodfjorden (northern Spitsbergen; water depth: 171 m) spanning the last ∼ 15 500 years.

“…However, the supply of turbid meltwater from land to the study area still resulted in a relatively high sediment accumulation rate. According to Risebrobakken et al (2011) and Groot et al (2014), the presence of Arctic Water suppressed the warming signal in the western Barents Sea. This observation is in agreement with our data on planktonic foraminifera reappearing at the termination of the early Holocene (ca.…”

Late Weichselian and Holocene palaeoceanography of Storfjordrenna, southern Svalbard

Abstract. Multiproxy analyses (including benthic and planktonic foraminifera, δ 18 O and δ 13 C records, grain-size distribution, ice-rafted debris, XRF geochemistry and magnetic susceptibility) were performed on a 14 C-dated marine sediment core from Storfjordrenna, located off of southern Svalbard. The sediments in the core cover the termination of Bølling-Allerød, the Younger Dryas and the Holocene and reflect general changes in the oceanography/climate of the European Arctic after the last glaciation. Grounded ice of the last Svalbard-Barents Sea Ice Sheet retreated from the coring site ca. 13 950 cal yr BP. During the transition from the subglacial to glaciomarine setting, Arctic Waters dominated the hydrography in Storfjordrenna. However, the waters were not uniformly cold and experienced several warmer spells. A progressive warming and marked change in the nature of the hydrology occurred during the early Holocene. Relatively warm and saline Atlantic Water began to dominate the hydrography starting from approximately 9600 cal yr BP. Although the climate in eastern Svalbard was milder at that time than at present (smaller glaciers), two periods of slight cooling were observed in 9000-8000 and 6000-5500 cal yr BP. A change in the Storfjordrenna oceanography occurred at the beginning of the late Holocene (i.e. 3600 cal yr BP) synchronously with glacier growth on land and enhanced bottom current velocities. Although cooling was observed in the Surface Water, Atlantic Water remained present in the deeper portion of the water column of Storfjordrenna.

A new integrated micropalaeontological study on planktonic and benthic foraminifera, calcareous nannofossils and diatoms was performed on three sediment cores from the Storfjorden Trough Mouth Fan to reconstruct the Late Quaternary palaeoenvironmental and climatic history. Two main intervals were discussed: the last deglaciation (16.2-11.7 ka BP) and the Holocene. The age model relies on palaeomagnetic parameters together with 10 radiocarbon dates. Deglacial sediments had largely diluted the biogenic content which was scarce and poorly preserved. The first occurrence of Cibicidoides wuellerstorfi (benthic foraminifer), together with Turborotalita quinqueloba (planktonic foraminifer) and Coscinodiscus spp. (diatoms) at 11.3 ka BP followed the end of the Younger Dryas cold event and marked the beginning of the early Holocene warm period. Diatoms and planktonic foraminifers indicated a warming of the surface water from 10.5 to 9.2 ka BP, identifying the Holocene Thermal Maximum event. Bottom water fauna registered these warming conditions less clearly. Cooling events were identified during the Holocene, in particular the 8.2 ka BP event and the Neoglacial between 3.2 and 2 ka BP, as shown by the presence of cold-water taxa such as Gephyrocapsa muellerae (nannoplankton) and Neogloboquadrina pachyderma (planktonic foraminifer). These events were influenced by sea ice extent, cold or relatively warm current influxes.
