Scientists from the GKSS Research Center confirm the predictions by the Volcanic Ash Center in London which had been frequently criticized by means of independent model simulations. In addition they provide estimates of ash particle concentrations. The model results were fortified by measurements.

Agostino Merico studied Physics at the University of Turin, Italy, and received his PhD in Ocean and Earth Science from the University of Southampton, UK, in 2003. He did his first postdoctoral experience at the National Oceanography Centre, Southampton. Between 2005 and 2010, Dr. Merico was Research Scientist at the GKSS Research Centre in Geesthacht, Germany.

Long-term changes in temperature can influence the productivity and composition of ecosystems. The analysis of the variations of ecological data over periods in which this human influence was not as pressing as today can, therefore, more clearly reveal linkages between climatic or environmental conditions and ecological productivity. This study attempted to disentangle the relationship between temperature variations and populations of Mediterranean tuna (Thunnus thynnus) between the 16th and 18th centuries by analyzing historical records of fish captures, temperature reconstructions based on proxy-data and simulation of past climates performed with a global climate climate model.

Today scientists at the Centre of Scientific Diving of the Biological Institute Helgoland start a project that is unique thus far for the North Sea: “MarGate”, an innovative underwater experimental field. “MarGate” is part of the COSYNA oceanographic research infrastructure coordinated by the GKSS Research Centre Geesthacht and financed within the research field “Earth and Environment” of the Helmholtz Association of German Research Centres.
