Deoxygenation in the Baltic Sea endangers fish yields and favours noxious algal blooms. Yet, vertical transport processes ventilating the oxygen-deprived waters at depth and replenishing nutrient-deprived surface waters (thereby fuelling export of organic matter to depth) are not comprehensively understood. Here, we investigate the effects of the interaction between surface currents and winds on upwelling in an eddy-rich general ocean circulation model of the Baltic Sea. Contrary to expectations...

In general, the over sea height is cumulative factor, which can influence significantly the farm conditions. This effect consists of temperature (mean year temperature), rain (sum of rainfulls), sunshine (total period of sunshine) and so on, in terms of climate, which can influence the dairy cow keeping directly and indirectly. Direct effects can influence the welfare of dairy cows in terms of hot stress for example, which could decrease a mastitis resistance of cows or their milk yield in simpl...

This paper draws a distinction between an anthropology of the sea and an anthropology as sea travel – using the latter as an epistemological window to understand immigrants’ experiences of long-distance sea travel which have rarely been considered in the anthropology of immigrant societies. The paper reviews Bronislaw Malinowski’s own travel linked to some explorations of archetypical sea voyages among the Trobriand Islanders (Argonauts of the Western Pacific, 1922). In a further step, the ‘ship...

Data stewardship is an essential element of the publication process. Knowing how to enact data polices that are described only in general terms can be difficult, however. Examples are needed to model the implementation of open-data polices in actual studies. Here we explain the procedure used to attain a high and consistent level of data stewardship across a special issue of the journal <i>Climate of the Past</i>. We discuss the challenges related to (1) determining which data are essentia...

Human activities and the consequent extinctions of native species and invasions of non-native species have been changing the composition of species assemblages worldwide. These anthropogenic impacts alter not only the richness of assemblages but also the biological dissimilarity among them. However, much of the research effort to date has focused on changes in taxonomic dissimilarity (i.e. accounting for species composition) whether assessments of functional dissimilarity (i.e. accounting for th...

Here we present an algorithm for continuous ice drift estimation based on coastal and ship radar data. The ice drift is estimated for automatically selected ice targets in the images. These targets are here called virtual buoys (VBs) and are tracked based on an optical flow method. To maintain continuous ice drift tracking new VBs are added after a given number of VBs have been lost; i.e. they can not be tracked reliably any more. Here we also apply the algorithm to data of three test cases to...

Although respiration-based oxidation of reduced carbon releases CO₂ into the environment, it provides an ecosystem with the metabolic energy for essential biogeochemical processes, including the newly proposed microbial carbon pump (MCP). The efficiency of MCP in heterotrophic microorganisms is related to the mechanisms of energy transduction employed and hence is related to the form of respiration utilized. Anaerobic organisms typically have lower efficiencies of energy transduction ...

Satellite observations of microwave brightness temperatures between 19 GHz and 85 GHz are the main data sources for operational sea-ice monitoring and retrieval of ice concentrations. However, microwave brightness temperatures depend on the emissivity of snow and ice, which is subject to pronounced seasonal variations and shows significant hemispheric contrasts. These mainly arise from differences in the rate and strength of snow metamorphism and melt. We here use the thermodynamic snow model SN...
