Title:PreliminarystudyonthesourceoforganicmatterinsedimentsofredtideareaintheEastChinaSeaanditsrelationshipwithphytoplanktoncommunity

Introduction:

Redtideisaworldwidephenomenonthatcausesseriousenvironmentalproblems.TheredtideintheEastChinaSeaisatypicalcoastalphenomenonresultingfromtheproliferationandaccumulationofharmfulalgalblooms.Organicmatterisoneofthemostimportantcomponentsofsedimentsinredtideareas.Itiscloselyrelatedtothegrowthandreproductionofphytoplanktonandcanaffectwaterqualityandecosystemhealth.Therefore,itisnecessarytoinvestigatethesourceanddistributionoforganicmatterinsedimentsofredtideareasandexploreitsrelationshipwithphytoplanktoncommunity.

Researchobjectives:

1.TodeterminethesourcesoforganicmatterinsedimentsofredtideareasintheEastChinaSeathroughstablecarbonisotopeanalysis;

2.Toanalyzethecompositionandabundanceofphytoplanktoninthewatercolumnandsedimentsofredtideareas;

3.Toexploretherelationshipbetweenorganicmatterandphytoplanktoncommunityinredtideareas.

Researchmethods:

1.CollectionofsedimentandwatersamplesfromredtideareasintheEastChinaSea;

2.Analysisofstablecarbonisotopecompositionoforganicmatterinsedimentstoidentifysources;

3.AnalysisofphytoplanktoncompositionandabundanceinsedimentsandwaterusingmicroscopyandHPLC;

4.Statisticalanalysistoexploretherelationshipbetweenorganicmatterandphytoplanktoncommunity.

Expectedresults:

1.Identificationofsourcesoforganicmatterinredtidesediments;

2.Analysisofphytoplanktoncompositionandabundanceinredtidesedimentsandwater;

3.Correlationanalysisbetweenorganicmatterandphytoplanktoncommunity,whichmightprovideinsightsintothemechanismsofredtideoccurrence.
