News editedby Peter Symes& Catherine G S Limdeep stuffNEWSThe Baltic Sea is full of unique and wellpreserved shipwrecks, some of whichdate back to the Medieval and VikingAges, that have now come underthreat from shipworms, Teredo navalis.Shipworms are notorious for borrowinginto and gradually destroying woodenstructures in saltwater. These animalsare capable of completely destroyinglarge maritime archaeological finds inonly ten years earning them the nickname“termites of the sea”. The shipworm,which is really a wood-boringmollusc, has avoided the Baltic Sea inthe past, since it does not do well in itslow salinity water, but it has now beenspotted in several locations along thealong both the Danish, Swedish andGerman Baltic Sea coasts.100,000 wrecks may be at riskThanks to the absence of Teredo navalisthere are currently around 100,000well-preserved shipwrecks resting in theBaltic Sea, a true treasure for historiansand archaeologists. If the shipwormcontinues to spread, these ships mayvanish before anyone has a chanceto explore them.Medievalshipwrecks attacked“Wrecks that have been restingunharmed since the 14th centuryhave now been attacked offthe coast of Rügen in Germany,and we are also noticing attacksalong the Swedish coast, includingdestruction of the Ribersborg coldbath house in Malmö,” says ChristinAppelqvist, with the Departmentof Marine Ecology, University ofGothenburg.Another artefact of global warming?Appelqvist and her colleagues suspectthat increased water temperaturesmay be helping the shipworm totolerate a lower salinity.The shipworm invasion could provedisastrous for marine archaeology inthe region, home to long-submergedprehistoric timber settlements andremarkably preserved wrecks—suchas the salvaged 17th century Swedishwarship, the Vasa, a major museumattraction in Stockholm.“Really nice tall ships with the mastand everything intact are still beingdiscovered,” Appelqvist said. “Everytime researchers go down there withremotely operated vehicles they findnew wrecks.”Shipworms greatly damagewooden hulls and marine piling,and have been the subjectof much study to find methodsto avoid their attacks. Coppersheathing was used on woodenships during the Age ofExploration, as a method ofpreventing damage by“teredo worms”. ■When shipworms boreinto submerged wood,bacteria in a specialorgan allow them todigest cellulose. Theexcavated burrow isusually lined with acalcareous tubeShipworms have slenderworm-like forms, butnonetheless possess thecharacteristic structures ofbivalves. The valves of theshell of shipworms are smallseparate parts locatedat the anterior end of theworm, used for excavatingthe burrow“Around 100 wrecksare already infested inthe Southern Baltic”Shipworm enters the Baltic,threatens wooden wrecks andmarine treasuresThe shipworm invasion could prove disastrous for marine archaeology in theregion, home to long-submerged prehistoric timber settlements and remarkablypreserved wrecks such as the salvaged 17th century Swedish warship the Vasa5 X-RAY MAG : 34 : 2010 EDITORIAL FEATURES TRAVEL NEWS EQUIPMENT BOOKS SCIENCE & ECOLOGY EDUCATION PROFILES PORTFOLIO CLASSIFIED
