Carbonate content of sediment core CRP-1 (Table 1)

Determinations of total carbonate content yield additional information, in the context of integrated investigations, thus enabling or enhancing the interpretation and characterisation of the depositional environment, the processes of sedimentation and the diagenesis of sediments. In the case of drillcores, they help us to discern vertical gradations of facies sequences that have repeating patterns or show changes through time. This report presents initial results of carbonate investigations on a total of 32 bulk samples from the Quaternary and Miocene strata of the CRP-1 borehole, which reached a final depth of 147.69 metres below sea floor (mbsf). Fifteen out of a total of 18 lithostratigraphic units in the core were sampled (Tab. 1). Fourteen samples (24.85-43.85 mbsf) belong to the Quaternary, whereas 18 samples (44.53-146.51 mbsf) originate from the Miocene strata. The sampling intervals varied from 1-5 m for the Quaternary, and 1-15 m for the Miocene. All the samples originated from sections of core representing not more than 1 cm thickness

Sample intervals and carbonate content of sediment core CRP-2/2A (Table 1)

Determinations of total carbonate contents on CRP-2/2A cores yield additional information and knowledge, thus enabling or enhancing the interpretation and characterization of the depositional environment, the sedimentation, and the diagesiesis of sediments. In case of drilling profiles, they help to discern vertical gradation of facies sequences with repeating patterns or with changes in time. A total of 74 bulk samples originating from the Quaternary, Miocene and Oligocene strata of the CRP-2 and CRP-2A boreholes, final depth 624.15 metres below sea floor (mbsf). 38 of a total of 41 lithostratigraphic units of the boreholes were sampled (Tab. 1). Two samples (7.11-16,97 mbsf) belong to the Quaternary, 1 sample (23.54 mbsf) belongs to the Pliocene, 12 samples (30.71-123.7 mbsf) to the Miocene, whereas 53 samples (135.24-623.81 mbsf) originate from the Oligocene strata. The sampling intervals vary from 7-9 m for the Quaternary, 5-12 m for the Miocene or 3-12 m for the Oligocene. All the samples originate from sections of the profile of not more than 1-2 cm thickness. The samples were partioned; the partions of the samples were used for investigations with regard to clay minerals (Ehrmann, 2000), heavy minerals (Polozek, 2000), and XRD analyses (Neumann & Ehrmann, 2000)

(Appendix 1) Carbonate content in relation to sediment type described for sediment core CRP-3

Determinations of total carbonate contents in the CRP-3 core yield additional information and knowledge, in the context of integrated investigations, thus enabling or enhancing the interpretation and characterization of depositional environment, sedimentation, and diagenesis. In the case of drilling profiles, they help to discern vertical gradation of facies sequences with repeating patterns or with changes in time. A total of 98 bulk samples originating from the Palaeogene strata (Early Oligocene and ?Late Eocene) in the CRP-3 borehole were studied, the depth interval being 0-823.11 metres below sea floor (mbsf). Ages for the Cenozoic strata (Fig. 1) are taken from the Cape Roberts Science Team (2000a, 2000b), Bücker et al. (this volume), and Sagnotti et al. (2000, this vol.) and are shown in the columns A and B of figure 1. No investigations were performed on the underlying ?Devonian strata from 823.11-939.42 mbsf (final depth). Twenty-eight of a total of 34 lithostratigraphic Cenozoic units of the borehole were sampled (Appendix 1). Fourty-seven samples (8.97-349.78 mbsf) are from the Early Oligocene section, whereas 51 samples (357.80-788.94 mbsf) originate from the Early Oligocene or ?Late Eocene strata. The sampling intervals are on average about 5-9 m for the Early Oligocene section and about 6-11 in in the Early Oligocene/?Late Eocene strata. All the samples were taken from sections of the profile of not more than 1-2 cm thickness. The samples were split; the portions of the samples were used for investigations with regard to clay minerals (Ehrmann, this volume), heavy minerals (Ehrmann, this volume), and mineralogy as revealed by XRD analyses (Neumann & Ehrmann, this volume)

Learning from Experience: Towards a Formal Model for Contextualization of Experiences for Quality Development

Quality development in e-learning becomes more and more important. A variety of quality approaches have been developed to improve educational processes in this field. The implementation of these approaches, however, often lacks success. One important reason is that experiences and recommendations are not systematically utilized for the implementation processes. The following article suggests a formal approach to collect and share experiences and recommendations to help users of quality approaches enhance their success by reusing experiences of others. Based on knowledge management principles, the contextualization of experiences will help to transfer them from one specific situation to a different context. The suggested approach is a result of the European Quality Observatory, an analysis and information platform for quality approaches in European e-learning
