Fishing is now extremely regulated, but research on and control of stocks is only extended to commercial species. Strict regulations have been made for drilling safety and pipelines are protected but the possibility that large accidents occur is not excluded. International rules have been made to restrict water pollution but there are many possibilities for exemption and evasion so that oil continues to pollute beaches, rivers like the Rhine still carry large concentrations of pollutants to the North Sea and so-called black listed substances are still being discharged in the coastal waters. At present the effects of human activity are especially noticeable in the coastal waters of the Southern North Sea and in the Southern Bight.","AbstractOtherLang":null,"BibLvlCode":"MS","StandardTitle":"Developments in the North Sea and their consequences for the marine environment","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-22 01:33:06.175990","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":1981,"DateUpdate":"2025-07-15","DateCreate":"2001-07-05","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":null,"monrec":{"MonID":12945,"ISBN":null,"PubliDate":1981,"IssueDate":null,"Volume":"1981","Issue":"2","Pagination":"33","Place":"Texel","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":5036,"SerRR":"Interne verslagen Nederlands Instituut voor Onderzoek der Zee.
