主 题:interannual variability dimethylsulfi de hindcasting generalized additive mixed modelling Yellow Sea
摘 要:The 22-year(1998-2019)surface seawater dimethylsulfi de(DMS)concentrations in the Yellow Sea(YS)were hindcasted based on satellite sea surface temperature(SST)and chlorophyll-a(Chl-a)data using a generalized additive mixed model(GAMM).A continuous monthly dataset of DMS concentration in the YS was obtained after using the data interpolation empirical orthogonal function(DINEOF)to reconstruct missing information in the ***,the interannual DMS variability in the YS was *** results indicated that the monthly climatological DMS concentration in the YS was 3.61 nmol/*** concentrations in the spring and summer were signifi cantly higher than those in the autumn and *** concentrations were highest in coastal YS waters and lowest primarily in off shore YS *** DMS variability between 1998 and 2019 was subdivided into two inverse phases:with the exception of the central YS,DMS increased before the turning point and decreased *** turning point in interannual DMS variation was earlier in the inshore YS as compared to the central *** analysis identifi ed some signifi cant patterns of interannual variation in the DMS anomaly in the *** a appeared to be the main factor infl uencing interannual trends in DMS in the *** DMS variability was under the joint control of Chl a and ***,short-term interannual DMS variation(2-3 years)was primarily related to SST,while longer term interannual DMS variation(6-8 years)was signifi cantly correlated with Chl a and SST.
