“…In the Niedersachsen Wadden Sea, like in many other places investigated (Perkins & Abbott, 1972;Nicholls et al, 1981;Reise, 1983), the bottom fauna under thick algal carpets undergoes a fast succession, coincident to the detailed description given by Pearson & Rosenberg (1978) for macrobenthic response to organic pollution. Mass mortality of bivalves is the most obvious effect, but polychaetes and meiofauna besides suffer from oxygen deficiency and toxic hydrogensulfide in the sediment.…”

“…During benthic surveys in the 1980s, this increase also became obvious in Niedersachsen (Michaelis et al, unpubl. ) Since the early 1970s, "green tides" of macroalgae, principally Ulva and Enteromorpha, have been reported from various sites of the European coasts: from the Swedish side of the Kattegat (Rosenberg, 1992), the Island of Funen in Denmark (Funen County Council, 1991), different places around the British Isles (Perkins & Abbott, 1972;Joint, 1978;Lowthion et al, 1985), the French coast of the Channel (Desprez et al, 1992;Piriou & M4nesguen, 1992) and the Adriatic Sea .…”

The distribution and cover density of macroalgae (Chlorophyta, Ulvaceae) were estimated by means of aerial surveys in 1990-1992 in the Wadden Sea of Niedersachsen, an intertidal area of some 1200 km 2 situated at the German North Sea coast. Each year, up to a maximum of 15 % of the total area was covered by algae. The spatial distribution was heterogeneous. In some subregions the macroalgal carpets covered from 30 % up to 60 % of the tidal flats.The cover density was at its peak in 1990. Additionally, tentative ground truth investigations were carried out on species composition. Reviewing other reports of macroalgal mass development at various sites in Europe, it is assumed that in the German Wadden Sea the recent macroalgal blooms have to be regarded as a response to eutrophication, and will presumably remain a chronic problem for many years to come.

“…9). The process of dislodged of filaments of U. prolifera and the subsequent forming of small floating patches which then aggregate and expand due to continued vegetative growth was described previously by Ho (1979) and Perkins and Abbott (1972). Using known growth rates for U. prolifera in the Yellow Sea of 10-37% per day (Liang et al, 2008), we calculated that 4956 tonnes of U. prolifera was sufficient to generate a green-tide of the 2008 magnitude (%1 million tonnes) within 17 and 56 days.…”

“…Extensive green algal mats in the vicinity of sewage outlets have been reported from several shores since the 1970s (i.e. Perkins & Abbott, 1972;Wharfe, 1977;Nicholls et al, 1981), and it was described for K6nigshafen by Reise (1983).…”

The situation regarding the distribution and abundance of seagrass, macroalgae and benthic fauna near the island of Sylt in the south-eastern North Sea during the period 1923 to 1940 is compared with that of the 1980s. Evidence of organic enrichment in recent times is provided by (1) massive growth of green algal mats on sheltered tidal flats, (2) a decline of red algae in the subtidal zone, (3) an expansion of mussel beds along low water line and down to 20 m depth, (4) increased abundance of polychaetes inhabiting intertidal and subtidal sandy bottoms. Seagrass beds have undergone complex changes which remain unexplained. Intensified erosion has contributed to the loss of habitats in the intertidal zone, and probably affected sessile epifauna in the deep channels. Here, direct removal and disturbance by the bottom-trawling fishery may also have contributed to the observed species impoverishment.
