A 1.3-Myr palaeoceanographic record from the continental margin off Dronning Maud Land, Antarctica
(Peer reviewed; Journal article, 2003-09-15)A 12.5 m long core was retrieved from the continental margin off Dronning Maud Land, Antarctica. Magnetostratigraphy, stable isotopes, 14C accelerator mass spectrometer and amino acid analyses indicate a continuous sediment ... -
Atlantic Ocean thermohaline circulation changes on orbital to suborbital timescales during the mid-Pleistocene
(Peer reviewed; Journal article, 2003-02-19)Mid-Pleistocene benthic ∂18O and ∂13C time series from the North Atlantic site 983 and Ceara Rise site 928 are compared to an array of existing isotopic records spanning the Atlantic basin and the geographic extremes of ... -
Combining biochemical methods to trace organic effluent from fish farms
(Peer reviewed; Journal article, 2017)The substitution of fish oils and fish meal with terrestrial components in the diets of farmed fin-fish offers a unique opportunity to trace organic effluents from fin-fish aquaculture into the marine environment. In this ... -
Consistent fluctuations in intermediate water temperature off the coast of Greenland and Norway during Dansgaard-Oeschger events
(Peer reviewed; Journal article, 2019-11-01)Rapid warmings epitomize the Dansgaard-Oeschger events that are recorded in Greenland ice cores and imprinted in ocean sediment cores. While the abrupt climate changes appear connected to perturbations in sea ice and ocean ... -
Eight-hundred-year temperature variability from the Norwegian continental margin and the North Atlantic thermohaline circulation
(Journal article, 2004-04-17)Four cores raised from the eastern Norwegian Sea and adjacent Norwegian fjords at sites influenced by Atlantic water have been investigated. Oxygen isotope analyses in benthic and planktonic foraminifera are used as a proxy ... -
Environmental changes off North Iceland during the deglaciation and the Holocene: foraminifera, diatoms and stable isotopes
(Peer reviewed; Journal article, 2004-02)A combined study of foraminifera, diatoms and stable isotopes in marine sediments off North Iceland records major changes in sea surface conditions since about 15800 cal years (yr) BP. Results are presented from two gravity ... -
Faunal trophic structure at hydrothermal vents on the southern Mohn's Ridge, Arctic Ocean
(Peer reviewed; Journal article, 2013)We explore the trophic ecology of heterotrophic fauna associated with a high temperature (HT) vent, 2 low temperature vents, a ‘near-HT vent’ habitat and a non-vent site situated at upper bathyal depths on the southern ... -
Holocene changes in atmospheric circulation recorded in the oxygen-isotope stratigraphy of lacustrine carbonates from northern Sweden
(Peer reviewed; Journal article, 2002)The oxygen-isotope composition of local precipitation (d18OP) is reconstructed from carbonate lake-sediment components in a sediment core covering the last 10000 calendar years from Lake Tibetanus, a small, hydrologically ... -
A Miocene (8–12 Ma) intermediate water benthic stable isotope record from the northeastern Atlantic, ODP Site 982
(Peer reviewed; Journal article, 2003-03-12)Oxygen and carbon isotope records are presented for the benthic foraminifer Cibicidoides wuellerstorfi from upper middle through lower upper Miocene (11.6–8.2 Ma) sediments recovered at intermediate water depth (1134 m) ...
