爱丝梅拉达号文化知识：船只为什么用女性名称命名？古希腊渔民经常称他们的渔船为“Artemida”，希望钓到好鱼。在希腊神话中，Artemis被认为是狩猎的女神和守护神。自古希腊以来，船一直以安全和保护的理念选择女性名称，因为水手们认为，这艘船将保护他们的旅程，就像母亲在怀孕期间照顾孩子一样。西方也迷信女子上船会有霉运。AlthoughtheEsmeraldawasfirstlocatedin1998,itwasexploredbymarinearchaeologistsbetween2013and2015.Researchersusedadvancedtechnologytoexaminesomeoftheobjectsontheship.Forexample,CTscanningwasusedtoidentifytwosilvercoinsandabell.marinearchaeologists海洋考古学家BackgroundInformationTheJiaolong,China’smanneddeep-seavessel,isnamedafteramythicalChineseseadragon.Atroughly8.2metreslong,3metreswideand3.4metreshigh,itweighsalmost22metrictons.In2012,itsettherecordforthedeepestdiveafterreachingadepthof7,062metresinthePacificOcean’sMarianaTrench.vessel
