Description: Information about geomarine sample collections should be recallable at any time and sample material should be permanently available for scientific examination. This can only be achieved by responsible archiving high quality samples in a collection and by documenting core information in databases of a network of world ocean sediment and rock collections. Science is in permanent progress. New questions are raised and new examination methods for the marine sediment and oceanic crust record are eveloped continuously to improve our understanding of hydrothermal, oceanographic and atmospheric processes. New and refined methods for studying marine sediment records allow to examine the sedimentary environment in more and more detail to monitor even short term changes. For example, studies of the Holocene sedimentary record are essential for an assessment of the distribution of pollutants and their impact on sea floor environments. Sediment core and oceanic crust records in archives are an indispensable part of geomarine research facilities. They are of major significance for the implementation of national and international projects to understand marine environmental changes. Scientific documents with guidelines for data collection, archiving and sampling were prepared on national and international levels under the auspices of PAGES and IMAGES to ensure a global array of high quality marine sedimentary records (Shackleton et al., 1990, Pisias et al., 1993). The core collection in Kiel presently consists of more than 2000 m of sediment samples from all oceans. Standard procedures for systematic collection of this material are used to keep the core material available for all scientists and for many decades. The cores are stored in sealed plastic tubes, which contain water saturated sponges to prevent the core from drying out, shrinking and cracking. Cold-storage rooms are used for splitted and unsplitted core sections to preserve deep ocean temperature conditions (~ 4°C).

Description: For the identification of a flowering plant the first step usually is to discover to which family it belongs. With some experience, the families commonly encountered in one\xe2\x80\x99s area of interest are soon known, but when dealing with specimens from other places, notably those from the vast and rich subtropics and tropics, there is much less certainty. The pertinent literature is often not readily available as it is often found only in expensive, rare or obscure books, or journals, present only in a few specialized institutes. Basically only a few keys to the families of flowering plants of the world have ever been produced, the best known of which at present is Hutchinson\xe2\x80\x99s Key to the families of flowering plants (1973); less well-known are Lem\xc3\xa9e\xe2\x80\x99s Tableau analytique des genres monocotyl\xc3\xa9dones (1941) (incl. Gymnosperms) and his Tableau analytique des genres dicotyl\xc3\xa9dones (1943), and Hansen and Rahn\xe2\x80\x99s Determination of Angiosperm families by means of a punched-card system (Dansk Bot. Ark. 26, 1969, with additions and corrections in Bot. Tidsskr. 67, 1972, 152-153, and Ibid. 74 1979, 177-178). Of note also are Davies and Cullen\xe2\x80\x99s The identification of flowering plant families, 2nd ed. (1979), which, however, deals only with the families native or cultivated in North Temperate regions, and Joly\xe2\x80\x99s Chaves de identifi\xc3\xa7\xc3\xa3o das fam\xc3\xadlias de plantas vasculares que ocorrem no Brasil, 3rd ed. (1977), which may be useful in other tropical areas too.\nThere are a number of excellent keys prepared by an Austrian, Franz Thonner (1863-1928), which deal either with European genera (1901, 1903, 1918), or African ones (1908, 1913, 1915), or with all families of the world (1891, 1895, 1917). Some of these have apparently been completely overlooked, others have been known only to a few, and then sometimes served as a base for keys of their own, thereby again influencing keys by others (see Derived works).

Description: The polychaetous worms collected by the Siboga-Expedition (1899-1900) are listed with some annotations. A few specimens \xe2\x80\x93 identified by Augener and Pettibone but never published \xe2\x80\x93 are added, so that this list gives a complete survey of all Polychaeta collected by the mentioned expedition. The types of 269 nominal species present in the Institute of Taxonomic Zoology (Zoological Museum), Amsterdam are incorporated in this list, for some species lectotypes are desinated.
