Shifting Sands

The Royal Geographical Society has reported on the practice and impact of marine aggregate dredging in the March 2008 edition of its magazine, Geographical. The report is titled “Shifting Sands”, and MARINET has contributed to this report. The article is introduced in the magazine by the following text: “Mining the seabed for sand and gravel […]

East Coast dredging sites

MARINET Briefing Paper

An in-detail guide (25 pages with illustrations) as to the nature and impact of dredging the seabed offshore from our coasts for sand and gravel for use by the construction industry.

Why are our Beaches eroding? — Coastal Zone ’07 paper

‘Coastal Zone 07’ was held at Portland, Oregon, from July 22nd to July 26th 2007 to discuss a wide range of coastal concerns. 920 delegates representing 16 countries attended. One session was devoted to the topic ‘Why are our beaches eroding?’ As this is very pertinent to our campaign, with the permission of Professor Vincent May, we have reproduced it in full.

Hallsands — hype and facts

When BBC first broadcast the superb ‘Coast’ programme, which did much to portray the value and wonders of our coastline, they included the story of Hallsands, that delightful Devon Village destroyed in 1917 by dredging. But subsequently …

Dredging Statistics for 2005

Details of the amounts of marine aggregate dredged offshore during 2005.

Coastal Erosion and Archaeological remains

The erosion of beaches and coasts, often due to aggregate dredging, can lead to the unearthing of significant archaeological remains, with examples from the UK.

North Norfolk Dredging Induced Erosion in Eurosion Report

The following is an extract from ‘Living with Coastal Erosion’ — Eurosion Policy Recommendations — December 2003. To see the report in its entirety go to www.eurosion.org/reports-online/reports.html Example Of Coastal Cliff Erosion The municipality of Happisburgh is a located in the county of North Norfolk (UK). Sediments are removed from the cliffs under the action […]

The Disappearing East Anglian Coast

The history, geology and meteorological events which have shaped the East Anglian coast and the likely impact of global warming.

USA — Dredging damage in Alabama

Scott Douglas, eminent coastal engineer with the University of Alabama, leaves no doubt as to erosion brought about by dredging. Where this was carried out by the U.S. Army Corps of Engineers, it has dramatically harmed Alabama beaches and necessitated ongoing restoration projects costing the public about $28 million. He maintains that such practices caused […]

Flawed Environmental Impact Assessment (EIA) studies on dredging impact

In addition to that we already have within Marine Dredging Briefing Paper and in the listing of scientific papers from around the world in the Marine Aggregate Dredging section, a new paper further evidences that we have long found, that much of the research on the damage resulting from offshore aggregate dredging (or, as these […]

CEFAS find no recovery of eco-system damage after offshore dredging

CEFAS (Centre for Environment, Fisheries & Aquaculture Science) Once BMAPA and their apologists claimed there was no long term impact on the seabed and its inhabitants from offshore aggregate dredging, stating that the seabed and the ecosystem dependant on it rapidly recovered from marine aggregate dredging. They are on record (on our MARINET video) for […]

UK study on seabed smothering from dredging

A paper giving insight into the damage created by dredging, specifically the smothering settlement of suspended ‘wash off’ sediments over the seabed, impacting the animals and plants that live on and within it, can be read here. It stresses how animals with delicate feeding or breathing apparatus, e.g. bivalve shellfish, can be intolerant to increased […]

Meeting the Dredgers

An account of a public meeting in 2005 in Norfolk between the aggregate companies and opponents of aggregate dredging, with details of the evidence presented to that meeting.

Germany — ‘In deep with marine environmental surveys — Exploiting sandbanks’

An application tested by SUMARE, relates to government-sanctioned offshore exploitation of sand on the Belgian continental shelf. However, there is concern that growing exploitation could lead to a reduction in size — or even disappearance — of the banks. In turn this could affect water currents and erosion/sedimentation characteristics of the area, and lead to […]

Netherlands — Assessment by Delft University

Dutch researchers from Delft University produced a paper, Assessing the Impact of Sand Extraction on the Shore Stability : Project for a Methodological Framework, assessing the impact of Offshore Aggregate Dredging on the shoreline given at the 20th-21st February 2003 European marine sand and gravel Conference (EMSAGG). It shows by graphical and mathematical models the […]

North Sea Surges

The Major Flood Risk to East Anglia

Our Disappearing Coastline

This original document was first written on 24th October 1995 for the North Sea Action Group’s website. Although superseded by later and more topical information, it still contains points of historical value. (1) History Many thousands of years ago there was no North Sea. East Anglia was joined by dense oak forests to the European […]

USA – Offshore Dredging Studies

Although several years old, the following study, Synthesis and Analysis of Existing Information Regarding Environmental Effects of Marine Mining produces some good information. It in part tells of the 2000 studies off Pea Island, North Carolina, USA, and how the North Carolina Geological Survey and University of Arkansas researchers found that shoalsshoal A sandbank or sandbar […]
