AbstractDuring the 2007 ‘Kor en Bot’ collecting trip across the Oosterschelde (province of Zeeland, southwest Netherlands), on board trawler cutter ZZ10, a stem fragment of a fossil isocrinid was recognised amongst the contents of the nets pulled on deck. This specimen is here interpreted to be of Early Jurassic age and assignable to the genus Isocrinus. However, because only internodals are preserved in this pluricolumnal, specific identification cannot be but approximate (Isocrinus (Chladocrinus) cf. tuberculatus). In the absence of any outcrop of Jurassic deposits in Zeeland and adjacent Dutch and Belgian territory, the most likely explanation is that this crinoid represents erratic material transported by precursors of the present-day River Maas (Meuse). Between the Langres Plateau and Sedan (northeast France), this river cuts through several occurrences of Lower Jurassic strata from which the present isocrinid might have originated. A less likely explanation is that it stems from boulders used for coastal reinforcement or from a Roman limestone votive altarpiece put up at the temple complex for the goddess Nehalennia, formerly present at Colijnsplaat, near Domburg (Noord-Beveland, Zeeland). Transportation from either northwest France or the southern or eastern United Kingdom, where there are coastal exposures of Jurassic strata, via the North Sea, is another option which, however, is also considered less feasible in view of the good state of preservation of the crinoid.

The following list has been classified, so far as practicable, according to subjects, in order that it may be useful for purposes of reference.

This chapter tells the story of how English got to be the weird way it is, which begins with the Germanic languages and the barbarians who spoke them. During the 5th century, an assortment of them poured across the North Sea, from what is today Denmark, the Netherlands, and Northern Germany, and conquered most of England. After about a century of the Germanic tribes taking over and settling in, the Romans returned. This time it was not soldiers but missionaries who arrived. The monks who came to convert the island to Christianity brought their Latin language with them, and they also brought the Latin alphabet. They set about translating religious texts into the language of the people they encountered, a language that by this time had coalesced into something that was Old English. However, there is another group of barbarians to blame: the Vikings. Their language was similar enough to Old English that they could communicate with the Anglo-Saxons without too much difficulty, and over time their own way of speaking mixed into the surrounding language, leaving vocabulary and expressions behind that do not quite fit the rest of the pattern at the old Germanic layer.

In the spring of 1920 the Ministry of Agriculture and Fisheries approached the Marine Biological Association of the United Kingdom with a view to the Association undertaking the manufacture of a large number of “Drift Bottles,” to be used in an extensive research into the resultant movements of the waters of the North Sea.

AbstractThe Seal Rehabilitation and Research Centre (SRRC) in Pieterburen, The Netherlands, rehabilitates seals from the waters of the Wadden Sea, North Sea and Southwest Delta area. Incidental observations of albinism and melanism in common and grey seals are known from countries surrounding the North Sea. However, observations on colour aberrations have not been systematically recorded. To obtain the frequency of occurrence of these colour aberrations, we analysed data of all seals admitted to our centre over the past 38 years. In the period 1971-2008, 3000 common seals (Phoca vitulina) were rehabilitated, as well as 1200 grey seals (Halichoerus grypus). A total of five albinistic common seals and four melanistic grey seals were identified. This results in an estimated incidence of albinism in common seals of approximately 1/600, and of melanism in grey seals of approximately 1/300. The seals displayed normal behaviour, although in the albinistic animals, a photophobic reaction was observed in daylight.
