Water mass characteristics and their temporal changes in a biological hotspot in the southern Chukchi Sea

We analysed mooring and ship-based hydrographic and biogeochemical data obtained from a Hope Valley biological hotspot in the southern Chukchi Sea. The moorings were deployed from 16 July 2012 to 19 July 2014, and data were captured during spring and fall blooms with high chlorophyll a concentrations. Turbidity increased and dissolved oxygen decreased in the bottom water at the mooring site before the fall bloom, suggesting an accumulation of particulate organic matter and its decomposition (nutrient regeneration) at the bottom. This event may have been a trigger for the fall bloom at this site. The bloom was maintained for 1 month in 2012 and for 2 months in 2013. The maintenance mechanism for the fall bloom was also studied by hydrographic and biogeochemical surveys in late summer to fall 2012 and 2013. Nutrient-rich water from the Bering Sea supplied nutrients to Hope Valley, although a reduction in nutrients may have occurred in 2012 by mixing of lower-nutrient water that would have remained on the Chukchi Sea shelf during the spring and fall blooms. In addition, nutrient regeneration at the bottom of Hope Valley could have increased nutrient concentrations and explained 60% of its nutrient content in fall 2012. The high nutrient content with the dome-like structure of the bottom water may have maintained the high primary productivity at this site during the fall bloom. Primary productivity was 0.3 g C m-2 d-1 in September 2012 and 1.6 g C m-2 d-1 in September 2013. The lower productivity in 2012 was related to strong stratification caused by the high fraction of surface sea ice meltwater.Discussion Paperhttp://www.godac.jamstec.go.jp/darwin/cruise/mirai/mr12-e03/

基于内毒素血症探讨皂术茵陈方对非酒精性脂肪性肝炎大鼠的影响

目的 基于内毒素血症探讨皂术茵陈方防治非酒精性脂肪性肝炎(NASH)大鼠的影响及其作用机制。方法 采用随机数字表法将40只大鼠分为5组,即正常组、模型组、皂术茵陈方组、盐酸吡格列酮组及培菲康组,每组8只。除正常组外,其余32只大鼠采用高脂饮食16周建立大鼠NASH模型,在造模第9周开始,皂术茵陈方组给予皂术茵陈方水提液60 mg/(kg·d)灌胃,盐酸吡格列酮组给予盐酸吡格列酮10 mg/(kg·d)灌胃,培菲康组给予培菲康210 mg/(kg·d)灌胃,正常组及模型组均给予双蒸水10 mL/(kg·d)灌胃,共治疗8周。第16周末经腹主动脉取血,生化法检测肝组织甘油三酯(TG)水平,苏木精—伊红(HE)染色观察肝组织病理学变化。终点显色法检测血浆内毒素(LPS)含量。ELISA法检测肝组织肿瘤坏死因子-α(TNF-α)、白细胞介素(IL)-1β、IL-6等炎症因子的表达水平。结果 与正常组比较,模型组大鼠肝组织显示出典型的NASH组织学特征,出现重度脂肪变性,不同程度的炎细胞浸润和坏死灶。大鼠肝湿重、肝指数、肝脏TG含量、血浆LPS水平、肝组织TNF-α、IL-1β、IL-6等炎症因..

Water mass characteristics and their temporal changes in a biological hotspot in the southern Chukchi Sea

We analysed mooring and ship-based hydrographic and biogeochemical data obtained from a Hope Valley biological hotspot in the southern Chukchi Sea. The moorings were deployed from 16 July 2012 to 19 July 2014, and data were captured during spring and autumn blooms with high chlorophyll a concentrations. Turbidity increased and dissolved oxygen decreased in the bottom water at the mooring site before the autumn bloom, suggesting an accumulation of particulate organic matter and its decomposition (nutrient regeneration) at the bottom. This event may have been a trigger for the autumn bloom at this site. The bloom was maintained for 1 month in 2012 and for 2 months in 2013. The maintenance mechanism for the autumn bloom was also studied by hydrographic and biogeochemical surveys in late summer to autumn 2012 and 2013. Nutrient-rich water from the Bering Sea supplied nutrients to Hope Valley, although a reduction in nutrients occurred in 2012 by the influence of lower-nutrient water that would have remained on the Chukchi Sea shelf. In addition, nutrient regeneration at the bottom of Hope Valley could have increased nutrient concentrations and explained 60% of its nutrient content in the bottom water in the autumn of 2012. The high nutrient content with the dome-like structure of the bottom water may have maintained the high primary productivity via the vertical nutrient supply from the bottom water, which was likely caused by wind-induced mixing during the autumn bloom. Primary productivity was 0.3 g C m-2 d-1 in September 2012 and 1.6 g C m-2 d-1 in September 2013. The lower productivity in 2012 was related to strong stratification caused by the high fraction of surface sea ice meltwater.http://www.godac.jamstec.go.jp/darwin/cruise/mirai/mr13-06/

Nutrient supply and biological response to wind-induced mixing, inertial motion, internal waves, and currents in the northern Chukchi Sea

A fixed-point observation station was set up in the northern Chukchi Sea during autumn 2013, and for about 2 weeks conductivity-temperature-depth (CTD)/water samplings (6-hourly) and microstructure turbulence measurements (two to three times a day) were performed. This enabled us to estimate vertical nutrient fluxes and the impact of different types of turbulent mixing on biological activity. There have been no such fixed-point observations in this region, where incoming low-salinity water from the Pacific Ocean, river water, and sea-ice meltwater promote a strong pycnocline (halocline) that stabilizes the water column. Previous studies have suggested that because of the strong pycnocline wind-induced ocean mixing could not change the stratification to impact biological activity. However, the present study indicates that a combined effect of an uplifted pycnocline accompanied by wind-induced inertial motion and turbulent mixing caused by intense gale-force winds (>10 m s-1) did result in increases in upward nutrient fluxes, primary productivity, and phytoplankton biomass, particularly large phytoplankton such as diatoms. Convective mixing associated with internal waves around the pycnocline also increased the upward nutrient fluxes and might have an impact on biological activity there. For diatom production at the fixed-point observation station, it was essential that silicate was supplied from a subsurface silicate maximum, a new feature that we identified during autumn in the northern Chukchi Sea. Water mass distributions obtained from wide-area observations suggest that the subsurface silicate maximum water was possibly derived from the ventilated halocline in the Canada Basin
