Late Campanian and Maastrichtian benthic foraminifera of El Kef, Tunesia, supplement to: Li, Liangquan; Keller, Gerta; Stinnesbeck, Wolfgang (1999): The Late Campanian and Maastrichtian in northwestern Tunisia: palaeoenvironmental inferences from lithology, macrofauna and benthic foraminifera. Cretaceous Research, 20(2), 231-252

Liangquan Li, Gerta Keller & Wolfgang Stinnesbeck
Late Campanian through Maastrichtian sea-level changes are examined based on lithology, macrofossils and benthic foraminifera at the Elles and El Kef sections in Tunisia. Six major sea-level regressions are identified during the late Campanian (74.4-74.2 Ma, 74.0-72.5 Ma), the Campanian-Maastrichtian transition (72.2-70.3 Ma), early Maastrichtian (69.6-69.3 Ma, 68.9-68.3 Ma), and late Maastrichtian (~65.5 Ma). Correlation of the Maastrichtian sea-level regressions with the oxygen isotope record of DSDP Site 525 in the middle latitude South Atlantic...

Sedimentological and palynological analysis of sediment cores from the northeastern Vietnamese Mekong River Delta, supplement to: Proske, Ulrike; Hanebuth, Till J J; Behling, Hermann; Nguyen, Van Lap; Ta, Thi Kim Oanh; Diem, Bui Phat (2010): The palaeoenvironmental development of the north-eastern Vietnamese Mekong River Delta since the mid-Holocene. The Holocene, 20(8), 1257-1268

Ulrike Proske, Till J J Hanebuth, Hermann Behling, Van Lap Nguyen, Thi Kim Oanh Ta & Bui Phat Diem
Three radiocarbon-dated sediment cores from the northeastern Vietnamese Mekong River Delta have been analysed with a multiproxy approach (grain size, pollen and spores, macro-charcoal, carbon content) to unravel the palaeoenvironmental history of the region since the mid Holocene. During the mid-Holocene sea-level highstand a diverse, zoned and widespread mangrove belt (dominated by Rhizophora) covered the extended tidal flats. The subsequent regression and coeval delta progradation led to the rapid development of a back-mangrove community dominated...

X-ray diffraction analysis, binocular component analysis and radiocarbon dating of sediment cores from the NW Iberian shelf system, supplement to: Lantzsch, Hendrik; Hanebuth, Till J J; Henrich, Rüdiger (2010): Sediment recycling and adjustment of deposition during deglacial drowning of a low-accumulation shelf (NW Iberia). Continental Shelf Research, 30(15), 1665-1679

Hendrik Lantzsch, Till J J Hanebuth & Rüdiger Henrich
Based on a well-established stratigraphic framework and 47 AMS-14C dated sediment cores, the distribution of facies types on the NW Iberian margin is analysed in response to the last deglacial sea-level rise, thus providing a case study on the sedimentary evolution of a high-energy, low-accumulation shelf system.Altogether, four main types of sedimentary facies are defined. (1) A gravel-dominated facies occurs mostly as time-transgressive ravinement beds, which initially developed as shoreface and storm deposits in shallow...

Sedimentological and palynological study of sediment cores from the northern Mekong River Delta, supplement to: Proske, Ulrike; Hanebuth, Till J J; Gröger, Jens; Diem, Bui Phat (2011): Late Holocene sedimentary and environmental development of the northern Mekong River Delta, Vietnam. Quaternary International, 230(1-2), 57-66

Ulrike Proske, Till J J Hanebuth, Jens Gröger & Bui Phat Diem
A sedimentological and palynological study of three sediment cores from the northern Mekong River Delta shows the regional sedimentary and environmental development since the mid-Holocene sea level highstand. A sub- to intertidal flat deposit of mid-Holocene age is recorded in the northernmost core. Shoreline deposits in all three cores show descending ages from N to S documenting 1) the early stages of the late Holocene regression and 2) the subsequent delta progradation. The delta plain...

Sedimentology of the Reykjanes Ridge, Southeast Greenland, supplement to: Lackschewitz, Klas S; Baumann, Karl-Heinz; Gehrke, B; Wallrabe-Adams, Hans-Joachim; Thiede, Jörn; Bonani, Georges; Endler, Rudolf; Erlenkeuser, Helmut; Heinemeier, Jan (1998): North Atlantic ice sheet fluctuations 10,000-70,000 yr ago as inferred from deposits on the Reykjanes Ridge, southeast of Greenland. Quaternary Research, 49(2), 171-182

Klas S Lackschewitz, Karl-Heinz Baumann, B Gehrke, Hans-Joachim Wallrabe-Adams, Jörn Thiede, Georges Bonani, Rudolf Endler, Helmut Erlenkeuser & Jan Heinemeier
Marine records from the Reykjanes Ridge indicate ice sheet variations and abrupt climate changes. One of these records, ice-rafted detritus (IRD), serves as a proxy for iceberg discharges that probably indicates ice sheet fluctuations. The IRD records suggest that iceberg discharge 68,000-10,000 yr B.P. happened more frequently than the 7000- to 10,000-yr spacing of the Heinrich events. An IRD peak 67,000 to 63,000 yr B.P. further suggests that the Middle Weichselian glaciation started about 12,000...

Paleoceanography on sediment core MD01-2416, supplement to: Sarnthein, Michael; Gebhardt, Holger; Kiefer, Thorsten; Kucera, Michal; Cook, M; Erlenkeuser, Helmut (2004): Mid Holocene origin of the sea surface salinity low in the Subarctic North Pacific. Quaternary Science Reviews, 23(20-22), 2089-2099

Michael Sarnthein, Holger Gebhardt, Thorsten Kiefer, Michal Kucera, M Cook & Helmut Erlenkeuser
IMAGES core MD01-2416 (51°N, 168°E) provides the first centennial-scale multiproxy record of Holocene variation in North Pacific sea-surface temperature (SST), salinity, and biogenic productivity. Our results reveal a gradual decrease in subarctic SST by 3-5 °C from 11.1 to 4.2 ka and a stepwise long-term decrease in sea surface salinity (SSS) by 2-3 p.s.u. Early Holocene SSS were as high as in the modern subtropical Pacific. The steep halocline and stratification that is characteristic of...

Stable isotope record and benthic foraminifera of sediment core MD01-2378, supplement to: Holbourn, Ann; Kuhnt, Wolfgang; Kawamura, Hiroshi; Jian, Zhimin; Grootes, Pieter Meiert; Erlenkeuser, Helmut; Xu, Jian (2005): Orbitally-paced paleoproductivity variations in the Timor Sea and Indonesian Throughflow variability during the last 460-ky. Paleoceanography, 20(3), PA3002

Ann Holbourn, Wolfgang Kuhnt, Hiroshi Kawamura, Zhimin Jian, Pieter Meiert Grootes, Helmut Erlenkeuser & Jian Xu
A high-resolution (~1-2 kyr) multiproxy record from the Timor Sea in the easternmost Indian Ocean (International Marine Global Change (IMAGES) Program Core MD01-2378, latitude 13°04.95'S, longitude 121°47.27'E, 1783 m water depth) closely tracks changes in intermediate water ventilation and paleoproductivity over the last 460 kyr within one of the main outflow passages of the Indonesian Throughflow. Spectral analysis of five different flux-based productivity proxies indicates spectral power concentrated in the 100 kyr (glacial-interglacial) and the...

Stable isotope ratios of foraminifera, grain-size distribution and magnetic susceptibility record of sediment core MD99-2339, supplement to: Voelker, Antje H L; Lebreiro, Susana Martin; Schönfeld, Joachim; Cacho, Isabel; Erlenkeuser, Helmut; Abrantes, Fatima F (2006): Mediterranean outflow strengthening during northern hemisphere coolings: A salt source for the glacial Atlantic? Earth and Planetary Science Letters, 245(1-2), 39-55

Antje H L Voelker, Susana Martin Lebreiro, Joachim Schönfeld, Isabel Cacho, Helmut Erlenkeuser & Fatima F Abrantes
High-resolution grain size and magnetic susceptibility records from the eastern Gulf of Cadiz (site MD99-2339; 1170m water depth) reveal contourites formed by the Mediterranean Outflow (MOW) during the last 47kyr BP. Oscillations in the MOW's intensity occurred in phase with Greenland temperature variations with a stronger outflow during northern hemisphere coolings such as Dansgaard-Oeschger stadials, Heinrich events, and the Younger Dryas. Benthic delta13C data implies the Western Mediterranean Deep Water as one of the main...

Age determination of sediment core SO75-26KL, Portuguese margin, supplement to: Zahn, Rainer; Schönfeld, Joachim; Kudrass, Hermann-Rudolph; Park, M-H; Erlenkeuser, Helmut; Grootes, Pieter Meiert (1997): Thermohaline instability in the North Atlantic during meltwater events: Stable isotope and ice-rafted detritus records from core SO75-26KL, Portuguese margin. Paleoceanography, 12(5), 696-710

Rainer Zahn, Joachim Schönfeld, Hermann-Rudolph Kudrass, M-H Park, Helmut Erlenkeuser & Pieter Meiert Grootes
A benthic isotope record has been measured for core SO75-26KL from the upper Portuguese margin (1099 m water depth) to monitor the response of thermohaline overturn in the North Atlantic during Heinrich events. Evaluating benthic delta18O in TS diagrams in conjunction with equilibrium deltac fractionation implies that advection of Mediterranean outflow water (MOW) to the upper Portuguese margin was significantly reduced during the last glacial (< 15% compared to 30% today). The benthic isotope record...

High-resolution isotope stratigraphy of ODP Site 184-1144, supplement to: Bühring, Christian; Sarnthein, Michael; Erlenkeuser, Helmut (2004): Toward a high-resolution stable isotope startigraphy of the last 1.1 m.y.: Site 1144, South China Sea. Proceedings of the Ocean Drilling Program, Scientific Results, 184, 1-29

Christian Bühring, Michael Sarnthein & Helmut Erlenkeuser
Narrow-spaced oxygen and carbon stable isotope records of the planktonic foraminifer Globigerinoides ruber (white) were obtained at Ocean Drilling Program Leg 184 Site 1144 to establish a first record of high-resolution Pleistocene monsoon variability on orbital to centennial timescales in the northern South China Sea. The new records extend from the Holocene back to marine isotope Stage (MIS) 34 (1.1 Ma). Sedimentation rates average 0.56 m/k.y. for the upper Matuyama and Brunhes Chrons and increase...

Age determination and stable isotope record of foraminifera of sediment core SO82_5-2, supplement to: van Kreveld, Shirley A; Sarnthein, Michael; Erlenkeuser, Helmut; Grootes, Pieter Meiert; Jung, Simon J A; Pflaumann, Uwe; Voelker, Antje H L (2000): Potential links between surging ice sheets, circulation changes, and the Dansgaard-Oeschger cycles in the Irminger Sea, 60-18 kyr. Paleoceanography, 15(4), 425-442

Shirley A van Kreveld, Michael Sarnthein, Helmut Erlenkeuser, Pieter Meiert Grootes, Simon J A Jung, Uwe Pflaumann & Antje H L Voelker
Surface and deepwater paleoclimate records in Irminger Sea core SO82-5 (59°N, 31°W) and Icelandic Sea core PS2644 (68°N, 22°W) exhibit large fluctuations in thermohaline circulation (THC) from 60 to 18 calendar kyr B.P., with a dominant periodicity of 1460 years from 46 to 22 calendar kyr B.P., matching the Dansgaard-Oeschger (D-O) cycles in the Greenland Ice Sheet Project 2 (GISP2) temperature record [Grootes and Stuiver, 1997, doi:10.1029/97JC00880]. During interstadials, summer sea surface temperatures (SSTsu) in...

Oxygen isotope and Mg/Ca record of planktonic foraminifera of sediment core MD01-2390, supplement to: Steinke, Stephan; Chiu, Han-Yi; Yu, Pai-Sen; Shen, Chuan Chou; Erlenkeuser, Helmut; Löwemark, Ludvig; Chen, Min-Te (2006): On the influence of sea level and monsoon climate on the southern South China Sea freshwater budget over the last 22,000 years. Quaternary Science Reviews, 25(13-14), 1475-1488

Stephan Steinke, Han-Yi Chiu, Pai-Sen Yu, Chuan Chou Shen, Helmut Erlenkeuser, Ludvig Löwemark & Min-Te Chen
Changes in the local freshwater budget over the last 22,000 years have been estimated from a sediment core located in the southern South China Sea (SCS) using a combined approach of Mg/Ca and oxygen isotopes on the planktonic foraminifera Globigerinoides ruber (white) sensu stricto (s.s.). Core MD01-2390 (06°28,12N, 113°24,56E; water depth 1591 m) is located near the glacial paleo-river mouths of the Baram, Rajang and North Sunda/Molengraaff Rivers that drained the exposed Sunda Shelf. The...

Geochemistry and stable isotope record of benthic foraminifera of Miocene sediments, supplement to: Holbourn, Ann; Kuhnt, Wolfgang; Schulz, Michael; Erlenkeuser, Helmut (2005): Impacts of orbital forcing and atmospheric carbon dioxide on Miocene ice-sheet expansion. Nature, 438, 483-487

Ann Holbourn, Wolfgang Kuhnt, Michael Schulz & Helmut Erlenkeuser
The processes causing the middle Miocene global cooling, which marked the Earth's final transition into an 'icehouse' climate about 13.9 million years ago (Myr ago) (Flower and Kennett, 1993, doi:10.1029/93PA02196; 1995 doi:10.1029/95PA02022; Miller et al., 1991, doi:10.1029/90JB0201; Zachos et al., 2001, doi:10.1126/science.1059412), remain enigmatic. Tectonically driven circulation changes (Kennett, 1977, doi:10.1029/JC082i027p03843); Woodruff and Savin, 1991, doi:10.1029/91PA02561) and variations in atmospheric carbon dioxide levels (Raymo and Ruddimann, 1992, doi:10.1038/359117a0; Vincent and Berger, 1985) have been suggested...

Sediment composition of the Central Arctic Ocean, supplement to: Spielhagen, Robert F; Baumann, Karl-Heinz; Erlenkeuser, Helmut; Nowaczyk, Norbert R; Nørgaard-Pedersen, Niels; Vogt, Christoph; Weiel, Dominik (2004): Arctic Ocean deep-sea record of Northern Eurasian ice sheet history. Quaternary Science Reviews, 23(11-13), 1455-1483

Robert F Spielhagen, Karl-Heinz Baumann, Helmut Erlenkeuser, Norbert R Nowaczyk, Niels Nørgaard-Pedersen, Christoph Vogt & Dominik Weiel
The sediment composition of deep-sea cores from the central Arctic Ocean, the Fram Strait, and the Yermak Plateau was analyzed for several parameters to reconstruct the history of marine paleoenvironment and terrestrial glaciation in the last 200,000 years. Layers with high amounts of coarse, terrigenous ice-rafted debris (IRD) and often high contents of smectite were deposited during extensive glaciations in northern Eurasia, when ice sheets reached the northern continental margins of the Barents and Kara...

Investigation of N. pachyderma from the North Atlantic, supplement to: Bauch, Dorothea; Darling, Kate; Simstich, Johannes; Bauch, Henning A; Erlenkeuser, Helmut; Kroon, Dick (2003): Palaeoceanographic implications of genetic variation in living North Atlantic Neogloboquadrina pachyderma. Nature, 424(6946), 299-303

Dorothea Bauch, Kate Darling, Johannes Simstich, Henning A Bauch, Helmut Erlenkeuser & Dick Kroon
The shells of the planktonic foraminifer Neogloboquadrina pachyderma have become a classical tool for reconstructing glacial-interglacial climate conditions in the North Atlantic Ocean. Palaeoceanographers utilize its left- and right-coiling variants, which exhibit a distinctive reciprocal temperature and water mass related shift in faunal abundance both at present and in late Quaternary sediments. Recently discovered cryptic genetic diversity in planktonic foraminifers now poses significant questions for these studies. Here we report genetic evidence demonstrating that the...

Temperature reconstruction of sediment core SO9-93KL, supplement to: Schulz, Hartmut; Emeis, Kay-Christian; Erlenkeuser, Helmut; von Rad, Ulrich; Rolf, Christian (2002): The Toba Volcanic Event and Interstadial/Stadial Climates at the Marine Isotopic Stage 5 to 4 Transition in the Northern Indian Ocean. Quaternary Research, 57(1), 22-31

Hartmut Schulz, Kay-Christian Emeis, Helmut Erlenkeuser, Ulrich von Rad & Christian Rolf
The Toba volcanic event, one of the largest eruptions during the Quaternary, is documented in marine sediment cores from the northeastern Arabian Sea. On the crest of the Murray Ridge and along the western Indian continental margin, we detected distinct concentration spikes and ash layers of rhyolithic volcanic shards near the marine isotope stage 5-4 boundary with the chemical composition of the "Youngest Toba Tuff". Time series of the Uk'37-alkenone index, planktic foraminiferal species, magnetic...

Age determination and stable isotope composition of sediment cores from the Arctic Ocean, supplement to: Nørgaard-Pedersen, Niels; Spielhagen, Robert F; Erlenkeuser, Helmut; Grootes, Pieter Meiert; Heinemeier, Jan; Knies, Jochen (2003): Arctic Ocean during the Last Glacial Maximum: atlantic and polar domains of surface water mass distribution and ice cover. Paleoceanography, 18(3), 1063

Niels Nørgaard-Pedersen, Robert F Spielhagen, Helmut Erlenkeuser, Pieter Meiert Grootes, Jan Heinemeier & Jochen Knies
On the basis of 52 sediment cores, analyzed and dated at high resolution, the paleoceanography and climate of the Last Glacial Maximum (LGM) were reconstructed in detail for the Fram Strait and the eastern and central Arctic Ocean. Sediment composition and stable isotope data suggest three distinct paleoenvironments: (1) a productive region in the eastern to central Fram Strait and along the northern Barents Sea continental margin characterized by Atlantic Water advection, frequent open water...

Heavy metals and carbon isotope concentrations in recent Baltic Sea sediments, supplement to: Erlenkeuser, Helmut; Suess, Erwin; Willkomm, Horst (1974): Industrialization affects heavy metal and carbon isotope concentrations in recent Baltic Sea sediments. Geochimica et Cosmochimica Acta, 38, 823-842

Helmut Erlenkeuser, Erwin Suess & Horst Willkomm
Recent sediment cores of the western Baltic Sea were analyzed for heavy metal and carbon isotope contents. The sedimentation rate was determined from radiocarbon dates to be 1.4 mm/yr. The 'recent age' of the sediment was about 850 yr. Within the upper 20 cm of sediment, certain heavy metals became increasingly enriched towards the surface; Cd, Pb, Zn and Cu increased 7-, 4-, 3- and 2-fold, respectively, whereas Fe, Mn, Ni and Co remained unchanged....

Investigation of planktic foraminifera from the Norwegian-Greenland Sea, supplement to: Simstich, Johannes; Sarnthein, Michael; Erlenkeuser, Helmut (2003): Paired d18O signals of Neogloboquadrina pachyderma (s) and Turborotalita quinqueloba show thermal stratification in Nordic Seas. Marine Micropaleontology, 48(1-2), 107-125

Johannes Simstich, Michael Sarnthein & Helmut Erlenkeuser
The vertical density gradients in the Nordic Seas are crucial for the preconditioning of the surface water to thermohaline sinking in winter. These gradients can be reconstructed from paired oxygen isotope data in tests of different species of planktonic foraminifera, the isotopic signatures of which represent different calcification depths in the water column. Comparison of d18O values from foraminiferal tests in plankton hauls, sediment traps, and nearby core top samples with the calculated d18Ocalcite profile...

Stable isotope ratios from foraminfera in Kara Sea sediments, supplement to: Simstich, Johannes; Stanovoy, Vladimir V; Bauch, Dorothea; Erlenkeuser, Helmut; Spielhagen, Robert F (2004): Holocene variability of bottom water hydrography on the Kara Sea shelf (Siberia) depicted in multiple single-valve analyses of stable isotopes in ostracods. Marine Geology, 206(1-4), 147-164

Johannes Simstich, Vladimir V Stanovoy, Dorothea Bauch, Helmut Erlenkeuser & Robert F Spielhagen
Ostracods secrete their valve calcite within a few hours or days, therefore, its isotopic composition records ambient environmental conditions of only a short time span. Hydrographic changes between the calcification of individuals lead to a corresponding range (max.-min.) in the isotope values when measuring several (>=5) single valves from a specific sediment sample. Analyses of living (stained) ostracods from the Kara Sea sediment surface revealed high ranges of >2per mil of d18O and d13C at...

Stable carbon and oxygen isotope record of Neogloboquadrina pachyderma and Cibicides lobatulus from the southwestern Greenland Sea, supplement to: Millo, Christian; Sarnthein, Michael; Erlenkeuser, Helmut; Frederichs, Thomas (2005): Methane-driven late Pleistocene d13C minima and overflow reversals in the southwestern Greenland Sea. Geology, 33(11), 873-876

Christian Millo, Michael Sarnthein, Helmut Erlenkeuser & Thomas Frederichs
A core transect across the southwestern Greenland Sea reveals coeval events of extremely negative planktic and benthic delta13C excursions between 40 and 87 ka. The most pronounced event, event 1, began at peak Dansgaard-Oeschger stadial 22 (85 ka) with a duration of 18 k.y. During this episode, incursions of Atlantic Intermediate Water caused a bottom-water warming of up to 8 °C. The amplitude, timing, and geographic pattern of the delta13C events suggest that this bottom-water...

Planktonic foraminifera and sea surface temperature reconstruction of sediments from the Mediterranean Sea, supplement to: Sperling, Michael R; Schmiedl, Gerhard; Hemleben, Christoph; Emeis, Kay-Christian; Erlenkeuser, Helmut; Grootes, Pieter Meiert (2003): Black Sea impact on the formation of eastern Mediterranean sapropel S1? Evidence from the Marmara Sea. Palaeogeography, Palaeoclimatology, Palaeoecology, 190, 9-21

Michael R Sperling, Gerhard Schmiedl, Christoph Hemleben, Kay-Christian Emeis, Helmut Erlenkeuser & Pieter Meiert Grootes
Water exchange between the Black Sea and the Mediterranean Sea has been a major focus of the paleohydrography of the eastern Mediterranean. Glacial melt water released from the Black Sea is a potential factor in the formation of sapropel S1, an organic-rich sediment layer that accumulated during the Early Holocene. A high-resolution study done on sediments from the Marmara Sea, the gateway between the Mediterranean and the Black Sea, sheds light on the Holocene exchange...

Stable isotope record of planktonic foraminifera from the western Iberian margin during marine isotope stage 2, supplement to: Voelker, Antje H L; de Abreu, Lucia; Schönfeld, Joachim; Erlenkeuser, Helmut; Abrantes, Fatima F (2009): Hydrographic conditions along the western Iberian margin during marine isotope stage 2. Geochemistry, Geophysics, Geosystems, 10, Q12U08

Antje H L Voelker, Lucia de Abreu, Joachim Schönfeld, Helmut Erlenkeuser & Fatima F Abrantes
The surface water hydrography along the western Iberian margin, as part of the North Atlantic's eastern boundary upwelling system, consists of a complex, seasonally variable system of equatorward and poleward surface and subsurface currents and seasonal upwelling. Not much information exists to ascertain if the modern current and productivity patterns subsisted under glacial climate conditions, such as during marine isotope stage (MIS) 2, and how North Atlantic meltwater events, especially Heinrich events, affected them. To...

Sedimentology and stable oxygen isotope record of the northern South China Sea, supplement to: Wang, Luejiang; Sarnthein, Michael; Grootes, Pieter Meiert; Erlenkeuser, Helmut (1999): Millennial reocurrence of century-scale abrupt events of East asian monsoon: A possible heat conveyor for the global deglaciation. Paleoceanography, 14(6), 725-731

Liping Wang, Michael Sarnthein, Pieter Meiert Grootes & Helmut Erlenkeuser
High-resolution sediment records from the South China Sea reveal a winter monsoon dominated glacial regime and a summer monsoon dominated Holocene regime during the last glacial cycle. A fundamental change between regimes occurred during deglaciation through a series of millennial reoccurrences of century-scale changes in the East Asian monsoon (EAM) climate. These abrupt events centered at 17.0, 15.9, 15.5, 14.7, 13.5, 13.9, 13.3, 12.1, 11.5, and 10.7 14C ka correlate well with the millennial-scale events...

Sea surface temperature reconstruction for Mediterranean Sea samples, supplement to: Emeis, Kay-Christian; Struck, Ulrich; Schulz, Hans-Martin; Rosenberg, Mark; Bernasconi, Stefano M; Erlenkeuser, Helmut; Sakamoto, Tatsuhiko; Martinez-Ruiz, Francisca C (2000): Temperature and salinity variations of Mediterranean Sea surface water over the last 16,000 years from records of planktonic stable oxygen isotopes and alkenone unsaturation ratios. Palaeogeography, Palaeoclimatology, Palaeoecology, 158(3-4), 259-280

Kay-Christian Emeis, Ulrich Struck, Hans-Martin Schulz, Mark Rosenberg, Stefano M Bernasconi, Helmut Erlenkeuser, Tatsuhiko Sakamoto & Francisca C Martinez-Ruiz
Alkenone unsaturation ratios and planktonic delta18O records from sediment cores of the Alboran, Ionian and Levantine basins in the Mediterranean Sea show pronounced variations in paleo-temperatures and -salinities of surface waters over the last 16,000 years. Average sea surface temperatures (SSTs) are low during the last glacial (averages prior to 13,000 years: 11-15°C), vary rapidly at the beginning of the Holocene, and increase to 17-18°C at all sites during S1 formation (dated between 9500 and...
