Meltwater pulses in the northern North Atlantic: retrodiction and forecast by numerical modelling

Towards quantitative sea ice reconstructions in the northern North Atlantic: A combined biomarker and numerical modelling approach

Subtropical iceberg scours and meltwater routing in the deglacial western North Atlantic

Abrupt centennial-to-millennial shifts inNorthernHemisphere climate during the last deglaciation are thought to have been triggered by the discharge of large volumes of meltwater and icebergs to the subpolar North Atlantic1. Here we show that meltwater and icebergswere also transporteddirectly from the Laurentide icemargin to the subtropicalNorthAtlantic in a narrow coastal current. We present ...

Bayesian hierarchical modelling of North Atlantic windiness

Extreme weather conditions represent serious natural hazards to ship operations and may be the direct cause or contributing factor to maritime accidents. Such severe environmental conditions can be taken into account in ship design and operational windows can be defined that limits hazardous operations to less extreme conditions. Nevertheless, possible changes in the statistics of extreme weath...

Numerical modelling of methyl iodide in the eastern tropical Atlantic

Methyl iodide (CH3I) is a volatile organic halogen compound that contributes significantly to the transport of iodine from the ocean to the atmosphere, where it plays an important role in tropospheric chemistry. CH3I is naturally produced and occurs in the global ocean. The processes involved in the formation of CH3I, however, are not fully understood. In fact, there is an ongoing debate whethe...

Floodplain Hazard Mapping in the Iranshahr River by Using Two-Dimensional Numerical Modelling and GIS

Today, the preparation of flood zoning maps is one of the basic and important issues in the study of development projects in the world; it is considered before any investment by the related organizations. In this paper, flood zoning was performed using the two-dimensional model HEC-RAS and GIS in order to assess the risk of the construction of a railway station near the bank of the Iranshahr Ri...
