According to the historian Nils Orvik, the Great War witnessed the decline of neutrality as a valuable foreign policy for small European states. The Netherlands was no exception and faced the daunting task of upholding its neutrality whilst resisting pressure from the two belligerent powers flanking the country (Germany and Britain). Neutrality entailed more than maintaining friendly relations with warring states, it also involved upholding strict standards of impartiality and territorial integr...

Terrestrial xanthophycean and chlorophyte algae have been studied at widespread Antarctic localities. All published literature (1847 to 1998) is reviewed on chlorophyte and xanthophycean algae from terrestrial and non-marine aquatic habitats of Maritime and Continental Antarctica. A checklist of all terrestrial and freshwater algae has been compiled from all literature from 1847 to 1998. This has shown that their diversity is not fully known because of inadequacy of collections and analyses of s...

Experimental tests of the theory of collective sea state modes of deep water surface gravity waves were made in a 20 meter long, 1.1 meter wide wind-wave tank. First, bursts of broadband wave energy were injected into the upwind end of the tank with a paddle. According to wave turbulence theory and previous experiments, it is expected that the collective mode can be seen as a change in the wind generated background spectral density propagating down the tank. The collective mode is expected to gi...

The deep sea. for a long time. had been perceived as a homogenous and stable environment, with little diversity. The discovery of island habitats such as hot vents. cold seeps and whale carcasses revealed the presence of high biomasses in the deep sea. Species richness on island habitats is low however, compared to the species richness on abyssal plains (Tunnicliffe 1991: Stecher et al. 2003). A study addressing species richness on abyssal plains concludes there to be tens of millions of new spe...

Gowan, Evan James

In the late Pleistocene, most of British Columbia and northern Washington was covered by the Cordilleran ice sheet. The weight of the ice sheet caused up to several hundred metres of depression of the Earth’s crust. This caused relative sea level to be higher in southwestern British Columbia despite lower global eustatic sea level. After deglaciation, postglacial rebound of the crust caused sea level to quickly drop to below present levels. The rate of sea-level fall is used here to determin...
