Speciation and transformation of phosphorus and its mixing behavior in the Bay of St. Louis estuary in the northern Gulf of Mexico

Water samples were collected for measurements of dissolved, colloidal, and particulate inorganic and organic phosphorus (P) from the Bay of St. Louis estuary in the northern Gulf of Mexico during August 2008 and October 2009. Laboratory mixing experiments were also carried out using end-member river water and seawater to examine key processes and mechanisms controlling the behavior of P during estuarine mixing. Dissolved organic P (DOP) was the dominant species in the total dissolved P (TDP) pool in both lower (S 25) regions, while dissolved inorganic P (DIP) predominated in mid-salinity regions (S of 10 similar to 20) comprising up to 75% of the TDP. Both DIP and DOP behaved non-conservatively during estuarine mixing showing dramatic changes and transformation between different P species. The total particulate phosphorus (TPP) accounted for up to 85% of total phosphorus (TP = TDP + TPP) in the low-salinity areas but fell to about 38% in higher salinity regions. The quasi-negative correlation between TDP and TPP and the similarity in mixing behavior between field observations and laboratory experiments supported our hypothesis that physicochemical processes, such as dynamic repartitioning between water and particles or adsorption/desorption, are the predominant mechanisms controlling the biogeochemical cycling of P species in the Bay of St. Louis. River export fluxes of DIP could be significantly underestimated without the quantification of particulate P species, especially in more pristine river basins. The value of the distribution coefficient (in terms of logK(d)) ranged from 4.4 to 5.6 and decreased with increasing suspended particulate matter concentration and salinity, indicating that P is highly particle reactive and the presence of colloidal P may play an important role in the cycling of P in estuarine environments. Colloidal inorganic P (CIP) and colloidal organic P (COP), as quantified by an ultrafiltration permeation model, comprised 0-62% of the DIP and 34-93% of the DOP with the highest values in the river mouth area, suggesting a river source for colloidal P. The % CIP dropped to below the detection limit as salinity increased, whereas % COP first decreased but increased again with increasing salinity, reflecting different sources for CIP and COP in the lower estuary. The DOC/DOP ratio decreased rapidly with increasing salinity indicating a diagenetically older dissolved organic matter pool from the river and a dynamic change in sources and chemical speciation of P in the estuary.

Distribution and source of transparent exopolymer particles in the northern Bering Sea

透明胞外聚合颗粒物(TEP)是海水中大量存在的黏性颗粒物质,它对于海洋颗粒物的聚集、有机碳的埋藏、食物网物质的传递、痕量金属的清除与迁出等均起着重要作用。本研究开展了夏季北白令海陆架、陆坡和海盆区透明胞外聚合颗粒物含量和分布的研究。结果表明,北白令海TEP含量介于34~628Mg/M3(XEQ)之间,其中陆架、陆坡和海盆区TEP的平均含量分别为240,145和83Mg/M3(XEQ),整体呈现由陆架向外海降低的趋势。在陆坡和海盆区,TEP含量随着深度的增加而降低,但在陆架近底层水中,观察到TEP高含量的特征,与近底层水高的TSM,POC相对应。TEP与荧光强度、TSM、POC等的关系分析显示,研究海域TEP存在两个来源,其一为海洋上层水体的浮游生物,其主要贡献于陆架上层、陆坡和海盆水体;其二为陆架沉积物的底栖生物,其通过沉积物再悬浮贡献于陆架近底层水。Transparent exopolymer particles(TEP) are large,sticky particles in marine environments,and play a significant role in particle dynamics,carbon export,food web energy transfer and scavenging of trace metals.Samples were collected from the northern Bering Sea during summer 2010 for measurements of TEP and other hydrographic parameters to examine the abundance,distributions and sources of TEP.Our results showed that TEP concentrations ranged from 34 to 628 mg/m3(Xeq).The averaged TEP concentrations in the shelf,slope and basin were 240,145 and 83 mg/m3(Xeq),respectively,showing a general decrease from the shelf to the basin.In the slope and basin areas,TEP concentrations decreased with the increasing depth.However,high concentrations of TEP were observed in the shelf bottom waters,coincided with the high values of TSM and POC.The correlations between TEP and fluorescence,TSM and POC suggested two sources of TEP in the northern Bering Sea:(1) in situ production from planktons in the upper water column,and(2) benthic biological processes in the sediments.High TEP concentrations in the shelf bottom waters was predominantly derived from sediment resuspension,which may have a potential effect on carbon biogeochemical cycle and scavenging of trace elements in shelf regions.中国第四次北极科学考察项目;海洋公益性行业科研专项(201105022-4);福建省自然科学基金项目(2009J06026
