Iron age maritime nodes on the English Channel coast.
… our understanding of late Iron Age cross-Channel interactions. The possibility of many other coastal sites being identified has been dismissed due to the assumption that they would be archaeologically unrecognisable. This study was established to review this question on the southern coast …

Extreme sea levels in the English Channel 1900 to 2006
… levels estimated from measured data, for the English Channel region.<br/><br/>A data archaeology exercise has been undertaken to extend the sea level records along the UK south coast. This exercise increased the sea level data set for this region by 173 years. These new records have been …

New approach to tidal stream energy analysis at sites in the English Channel
… maximum energy<br/>extraction in simple tidal channels have been produced, but they have not<br/>been extended to more complex open-boundary cases such as flow around<br/>headlands and islands. There is therefore a role for site-specific numerical<br/>modelling, which when validated, offers the …

Fish landings, discards and benthic material from demersal trawling in the western English Channel (ICES VIIe)
This study examined the impact of inshore single boat otter trawling from Newlyn, Looe, Plymouth and Salcombe and pair boat demersal trawling from Looe and Plymouth on the benthic environment off the SW peninsula of the UK between 1998 and 2000. Fish and shellfish species (54 and 11 species …

What is driving the range extension of Gibbula umbilicalis (Gastropda, Trochidae) in the eastern English Channel?.
… as Kent. Since the 1990s temperatures in the English Channel have increased faster (and to higher levels) than during any other period recorded. The importance of sea temperature driving the range extension of Gibbula umbilicalis has not been fully evaluated. Field and laboratory studies were …

Effect of future CO2 and temperature regimes on phytoplankton community composition, biomass and photosynthetic rates in the western English Channel
… natural communities sampled from the western English Channel (WEC). Elevated pCO2 increased phytoplankton biomass by up to 20-fold while elevated temperature resulted in an increase of up to 14-fold. Light-saturated photosynthetic carbon fixation rates increased > 6-fold under elevated pCO2 …

An investigation of factors influencing the spatial and temporal distribution of surface phytoplankton in the English Channel and Bay of Biscay in 2003 and 2004
… dinoflagellate bloom<br/>occurred in the western English Channel. The bloom was composed of a monspecific<br/>surface population of Karenia mikimotoi, giving cell densities up to 8000 cells ml-1 and<br/>chlorophyll a concentrations up to 70 mg m-3. Development of this dinoflagellate bloom<br/>in …

THE IMPACTS OF ATMOSPHERICALLY DERIVED METALS ON COASTAL MARINE SYSTEMS
… work, refined budgets for Ni and Pb for the English Channel were presented. The budgets clearly indicated the importance of the English Channel sediments as both a sink (Ni) and a source (Pb). Aerosol concentrations in the Red Sea Marine Aerosol (RSMA) for the crustally sourced elements Al, …

Vibrionaceae genome dynamics
… data bacterial samples were collected from the English Channel and sequenced to identify potential gene flow in a natural population to species of other bacterial families.

Sea level variability: examples from the Atlantic coast of Europe
… data have been analysed for (6) ports around the English Channel, and (5) around the Iberian Peninsula. A separate statistical analysis is used for the components of sea level variability: mean sea level, tides and meteorological residuals (surges). Extremes and percentiles of some of these …

Tides of War: Privateering, The British Economy, and The Winning of the American Revolution, 1772-1783
… were bold enough to capture enemy ships in the English Channel. This strategy so disrupted the British economy that it turned the tide of public opinion against the war, helped convince the French that victory was possible, and provided invaluable foreign aid to sustain the Continental Army and …

Studies of sediments in a tidal environment
… changes experienced by the region and the English Channel. The development and characteristics of the present day hydrodynamical regime, its adaptation to the presence of the Breakwater and the response of the sea bed to this feature are identified by combining information from these …

The artistic discovery of Assyria by Britain and France 1850 to 1950
… in the contemporary press, on both sides of the English Channel. Some artists, such as Gustave Doré, successfully maintained careers in both London and Paris. It is therefore often meaningless to speak of a wholly ‘French’ or ‘British’ reception, since these responses were coloured by artistic …

Factors that impact Pseudo-nitzschia spp. occurrence, growth, and toxin production
… Pseudo-nitzschia (PN) dynamics in the western English Channel (L4) and the environmental factors impacting on domoic acid (DA) production in these waters. This is combined with laboratory studies examining key environmental factors and the multifactorial impact of multiple macronutrient and …

The Maritime archaeology of a modern conflict: comparing the archaeology of German submarine wrecks to the historical text.
… UK Hydrographic Office marine surveys in the English Channel (the thesis Study Area) have helped uncover the wrecks of 63 German submarines (U-boats) sunk in both world wars. The author began to systematically dive on and record the wrecks in 1997, when it became clear that the distribution …
