Norwegian farmers' diaries used for quality control and calibration of early instrumental observations, and for temperature reconstructions
(The University of Bergen, 2008-06-10)
Mixing of the Storfjorden overflow (Svalbard Archipelago) inferred from denstity overturns
(American Geophysical Union, 2004-01-03)
Observations were made of the dense overflow from Storfjorden from a survey conducted at closely spaced stations in August 2002. The field data set consists of conventional conductivity-temperature-depth profiles and ...
The effect of radiation screens on Nordic time series of mean temperature
(Royal Meteorological Society, 1997-12)
A short survey of the historical development of temperature radiation screens is given based upon research in the archives of the Nordic meteorological institutes. In the middle of the nineteenth century most thermometer ...
On the dynamics of two efﬁcient malaria vectors of the Afrotropical region: Anopheles gambiae s.s. and Anopheles arabiensis
(The University of Bergen, 2013-08-19)
Weather and climate are only some of the factors influencing the dynamics of malaria. With the ongoing debate on the consequences of climate change, there is a need for models which are designed to address these questions. ...
Evaluation of ocean carbon cycle models with data-based metrics
(American Geophysical Union, 2004-04-02)
New radiocarbon and chlorofluorocarbon-11 data from the World Ocean Circulation Experiment are used to assess a suite of 19 ocean carbon cycle models. We use the distributions and inventories of these tracers as quantitative ...
Atlantic Ocean thermohaline circulation changes on orbital to suborbital timescales during the mid-Pleistocene
(American Geophysical Union, 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 ...
Aspects on interactions between mid- to high latitude atmospheric circulation and some surface processes
(The University of Bergen, 2006-06-08)
The Arctic is a hot topic in Climate Research. A large number of signs of a warming Arctic Climate have been identified the latest years. This is of major concern in light of the increasing atmospheric content of greenhouse ...
Pleistocene vertical carbon isotope and carbonate gradients in the South Atlantic sector of the Southern Ocean
(American Geophysical Union and the Geochemical Society, 2003-01-10)
We demonstrate that the carbon isotopic signal of mid-depth waters evolved differently from deep waters in the South Atlantic sector of the Southern Ocean during the Pleistocene. Deep sites (>3700 m) exhibit large ...
Last Glacial Maximum over China: Sensitivities of climate to paleovegetation and Tibetan ice sheet
(American Geophysical Union, 2003-02-06)
With the boundary conditions appropriate for the Last Glacial Maximum (LGM), including ice sheets, sea surface temperatures, sea-ice distribution, atmospheric CO2 concentration, the Earth’s orbital parameters, topography, ...
The sensitivity of the present day Atlantic meriodinal overturning circulation to freshwater forcing
(American Geophysical Union, 2003-09-09)
Mounting evidence indicates that the Atlantic Meridional Overturning Circulation (AMOC) was strongly reduced during cold climate episodes in the past, possible due to freshwater influx from glacial melting. It is also ...
