FS Heincke HE195
|Ship name (ship code)||FS Heincke (06HK)|
|Cruise period||2003-08-14 — 2003-08-23|
|Port of departure||Helgoland, Germany|
|Port of return||Helgoland, Germany|
|Objectives||This cruise is part of the activities of the Research Center Ocean Margins located at the University of Bremen, Germany, sponsored by the Deutsche Forschungsgemeinschaft (DFG). The scientific work is also part of a planned international collaborative project to reconstruct the environmental and climatic history of the North Sea during the late millenia (project partners are Germany, Netherlands, UK).
In the framework of this project the question is how the environmental, climatic and oceanographic conditions changed in the Northern North Sea during the last millennia (late Holocene). The aim of the cruise is to collect geological and biological samples from the Fladen Ground, the Dutch Bank southeast of the Fair Isle Channel, and the Bressay Ground, UK. Main focus will be given to the collection of mollusc shells of Arctica islandica, of surface sediment samples as well as sediment cores.
We will carry out echosounding profiles for the identification of geological sampling sites. Station work will focus on the collection of the shells of the mollusc, Arctica islandica (both living and dead specimens) for paleoenvionmental and paleoclimatic studies. Surficial sediment samples will be taken with a grab sampler, a small multi corer, a box corer. Sediment core samples will be collected to achieve the late Holocene sediment record from the northern North Sea for paleoclimatic studies (AMS 14C dating, logging methods, stable isotope analysis). Water samples will be obtained from a Niskin water sampler for analysis of stable isotopes (delta13C and delta18O) for calibration of geological proxy data (from shells and sediments).
