    • Calving rates at tidewater glaciers vary strongly with ocean temperature 

      Luckman, Adrian; Benn, Doug; Cottier, Finlo; Bevan, Suzanne; Nilsen, Frank; Inall, Mark (Peer reviewed; Journal article, 2015-10-09)
      Rates of ice mass loss at the calving margins of tidewater glaciers (frontal ablation rates) are a key uncertainty in sea level rise projections. Measurements are difficult because mass lost is replaced by ice flow at ...

    • Early Pliocene onset of modern Nordic Seas circulation related to ocean gateway changes 

      De Schepper, Stijn; Schreck, Michael; Beck, Kristina Marie; Matthiessen, Jens; Fahl, Kirsten; Mangerud, Gunn (Peer reviewed; Journal article, 2015-10-28)
      The globally warm climate of the early Pliocene gradually cooled from 4 million years ago, synchronous with decreasing atmospheric CO2 concentrations. In contrast, palaeoceanographic records indicate that the Nordic Seas ...

    • Hydrothermal vent fields and chemosynthetic biota on the world's deepest seafloor spreading centre 

      Connelly, Douglas P.; Copley, Jaonathan T.; Murton, Bramley J.; Stansfield, Kate; Tyler, Paul A.; German, Cristopher R.; Van Dover, Cindy L.; Amon, Diva; Furlong, Maaten; Grindlay, Nancy; Hayman, Nicholas; Hühnerbach, Veit; Judge, Maria; Le Bas, Tim; McPhail, Stephen; Meier, Alexandra; Nakamura, Koichi; Nye, Verity; Pebody, Miles; Pedersen, Rolf B.; Plouviez, Sophia; Sands, Carla; Searle, Roger C.; Stevenson, Peter; Taws, Sarah; Wilcox, Sally (Journal article, 2012-01-10)
      The Mid-Cayman spreading centre is an ultraslow-spreading ridge in the Caribbean Sea. Its extreme depth and geographic isolation from other mid-ocean ridges offer insights into the effects of pressure on hydrothermal ...

    • Large mesopelagic fishes biomass and trophic efficiency in the open ocean 

      Irigoien, Xabier; Klevjer, Thor A.; Røstad, Anders; Martinez, U.; Boyra, G.; Acuna, J. L.; Bode, A.; Echevarria, F.; Gonzalez-Gordillo, J. I.; Hernández-León, Santiago; Augsti, S.; Aksnes, Dag Lorents; Duarte, C. M.; Kaartvedt, Stein (Peer reviewed; Journal article, 2014-02-07)
      With a current estimate of ~1,000 million tons, mesopelagic fishes likely dominate the world total fishes biomass. However, recent acoustic observations show that mesopelagic fishes biomass could be significantly larger ...

    • North Atlantic storm track changes during the Last Glacial Maximum recorded by Alpine speleothems 

      Luetscher, Marc; Boch, Ronny; Sodemann, Harald; Spötl, Christoph; Cheng, Hai; Edwards, Roger Lawrence; Frisia, Silvia; Hof, Florian; Müller, Wolfgang A. (Peer reviewed; Journal article, 2015-02-27)
      The European Alps are an effective barrier for meridional moisture transport and are thus uniquely placed to record shifts in the North Atlantic storm track pattern associated with the waxing and waning of Late-Pleistocene ...

    • Plant macrofossil evidence for an early onset of the Holocene summer thermal maximum in northernmost Europe 

      Väliranta, Minna; Salonen, J. Sakari; Heikkilä, Maija; Amon, Leeli; Helmens, Karin; Klimaschewski, Andrea; Kuhry, P.; Kultti, Seija; Poska, Anneli; Shala, Shyhrete; Veski, Siim; Birks, Hilary H. (Peer reviewed; Journal article, 2015-04-10)
      Holocene summer temperature reconstructions from northern Europe based on sedimentary pollen records suggest an onset of peak summer warmth around 9,000 years ago. However, pollen-based temperature reconstructions are ...

    • Solar forcing synchronizes decadal North Atlantic climate variability 

      Thiéblemont, Rémi; Matthes, Katja; Omrani, Nour-Eddine; Kodera, Kunihiko; Hansen, Felicitas (Peer reviewed; Journal article, 2015-09-15)
      Quasi-decadal variability in solar irradiance has been suggested to exert a substantial effect on Earth’s regional climate. In the North Atlantic sector, the 11-year solar signal has been proposed to project onto a pattern ...

    • Thermodynamic controls of the Atlantic Niño 

      Nnamchi, Hyacinth C; Li, Jianping; Kucharski, Fred; Kang, In-Sik; Keenlyside, Noel; Chang, Ping; Farneti, Riccardo (Peer reviewed; Journal article, 2015-11-26)
      Prevailing theories on the equatorial Atlantic Niño are based on the dynamical interaction between atmosphere and ocean. However, dynamical coupled ocean-atmosphere models poorly simulate and predict equatorial Atlantic ...
