  Sediment distribution German North Sea - classification according to FIGGE (1981)

The map at a scale of 1 : 250,000 represents the sediment distribution according to FIGGE (2013). This is based on a percentage distribution of the three summarized grain size fractions 0.063-0.25 mm, 0.25-0.5 mm and 0.5-2 mm developed by FIGGE (1981), which are subdivided into 4 sand classes in a triangular diagram. In addition, the content of the fine fraction < 0.063 mm is distinguished in the proportions 0-5 %, 6-10 %, 11-20 %, 21-50 % and > 50 % as well as fraction >2 mm (gravel, cobbles, solid rock). The map presentation is based on sediment samples from the seafloor surface down to a depth of 0.2 m and layer descriptions from boreholes at a depth of 0.2 m, which were available in the German North Sea area until November 2012. The basic data are stored in databases at the BSH and LBEG, and data collected in the future will be integrated into them. The map shows areas of similar unconsolidated sediments at the seafloor surface. Unconsolidated sediments are classified according to their grain size according to DIN EN 14688-1: Clay (grain size <0.002 mm); Silt (grain size 0.002 to 0.063 mm); Sand (grain size 0.063 to 2.0 mm); Gravel (grain size 2.0 to 63 mm); cobblesand boulders (>63 mm). Based on the grain size analyses carried out in the laboratory and the layer descriptions from boreholes, grain size ranges are summarized for corresponding questions and then classified.

Quality and validity

Lineage
Die verwendete Datengrundlage umfasst 37254 nach FIGGE klassifizierte Punktdaten, die 26965 Korngrößenanalysen anhand von Oberflächenproben im Teufenspektrum bis 0,2 m GOK beinhalten. Zusätzlich wurden Schichtdaten von 10289 Bohrungen in 0,2 m GOK aus der Bohrdatenbank (BDN) abgegriffen und mit der im Projekt entwickelten MeMaS-Methode „BDN_Korngrößenklassen“ prozentuale Korngrößenverteilungen berechnet. Anschließend konnten diese Daten nach FIGGE klassifiziert und in die Kartenerstellung integriert werden. Die Datenbasis umfasst alle im GPDN-Projekt bis zum 29.10.2012 akquirierten und qualitätsgesicherten Datenbestände der Kooperationspartner BSH, BGR, LBEG, sowie externen Datenhaltern WSV, BGS, BfG, TNO, WTD 71/FWG, Senckenberg, Windparkfirmen, OAM-DEME GmbH, NLWKN, BARD Engineering GmbH, Jade Weser Port, LLUR, AWI, HPA, ICBM, EnBW AG, GPDN-Schiffsexpeditionen. Eine detaillierte Information ist in der Dokumentation vom 25.06.2013 beschrieben.
