西北太平洋部分海域AVHRR、TMI与MODIS遥感海表层温度的初步验证

选取[10～35°N,110～165°E]的西北太平洋海域,利用2002年7月～2005年12月Argo浮标数据对AVHRR/MODIS/TMI SST的daily（升轨）数据进行验证.结果表明：AVHRR/MODIS/TMI daily SST与Argo浮标5～6 m层温度总体的均方差rms在0.6～0.9℃,平均偏差bias在-0.2～0.2℃,平均绝对偏差bias_abs在0.3～0.7℃.这与三传感器全球范围的SST反演目标相当,说明在本区域SST反演不存在显著偏差.各遥感SST与浮标温度的差异存在季节变化,夏季偏高,很可能与夏季垂直混合较弱,比对采用的实测水温与海表温度差距较大有关.在3种遥感SST中,TMISST偏离实测值的程度最高,且偏离范围较大.作者认为这与该区域黑潮经过,产生诸多涡旋和锋面,SST时空变化剧烈而TMI空间分辨率较低有关.本研究将为此西北太平洋海域的多源SST融合提供一个比较可靠的依据.     

Benthic foraminiferal fauna turnover at 2.1 Ma in the northern South China Sea

Quantitative analysis of benthic foraminifera from ODP Site 1146 in the northern South China Sea (SCS) shows that abundance of Bulimina alazanensis, sometimes up to about 90%, decreased gradually since 3.2 Ma, especially at 2.1 Ma. Abundance of other benthic foraminiferal species, Globobulimina sub-globosa and Cibicidoides wuellerstorfi, increased after 2.1 Ma. Comparison with changes in oxygen and carbon isotopes of planktonic and benthic foraminifera shows that high abundance values of B. alazanensis corresponded with lower values of oxygen isotope, but for carbon isotope, high values of the species were consistent with heavier carbon isotope of benthic foraminifera and lighter carbon isotope of planktonic foraminifera, respectively, and vice versa. Considering factors such as uplift of Bashi Strait, expansion of the North Hemisphere Glaciation, strengthening of East Asian winter mon-soon and variations in oxygen and carbon isotope of foraminifera, changes of B. alazanensis in ODP Site 1146 suggest that the source of deep water masses of the northern South China Sea changed from the warm Pacific deep water with high oxygen content to Pacific Intermediate water with low oxygen content at 2.1 Ma. In addition, the strengthened East Asian winter monsoon resulted in increased pri-mary productivity, high nutrient and suboxic bottom water. Variations in species of B. alazanensis seemed to be unable to tolerate environmental stress induced by deep water masses and productivity changes.

英国海洋科技组织机构的建设现状及对我国的启示

随着新一轮海洋科技管理体制改革的开展,我国的海洋科技管理组织架构及资助体系处在进一步调整与优化的关键期。世界范围内,英国海洋事业发展具有独特意义。本文选取英国研究与创新署、自然环境研究理事会、国家海洋学中心、普利茅斯海洋实验室等为主要研究对象,梳理了英国海洋科技组织架构和资助情况,总结了其建设发展的相关经验,并总结相关启示,一是做好海洋科技管理资助体系顶层设计,依法进行改革创新;二是建立海洋领域资深专家学者库,定期进行项目汇报,保证项目评审全过程的专业性和项目完成质量;三是促进市场化、多元化的对外合作发展模式;四是注重学科长期研究和海洋学复合型人才培养。     

Sea surface temperature and terrestrial biomarker records of the last 260 ka of core MD05-2904 from the northern South China Sea

This paper reports high-resolution biomarker records of the last 260 ka for core MD05-2904 from the northern South China Sea （SCS）. The sea surface temperature （SST） record using the U37^k＇, index reveals a minimum of 21.5℃（MIS 2） and a maximum of 28.3℃（MIS 5.5）, for a temperature difference of almost 7℃, and provides the longest high-resolution U37^k＇ SST record in northern SCS. The content of odd-number long chain n-alkanes and several n-alkanes indexes such as the CPI, ACL and the C31/C27 ratio, all reveal generally higher values during the glacials and lower values during the interglaclals. Terrestrial input as Indicated by n-alkane content was mostly controlled by sea-level changes： During the glacials, lower sea-level exposed the continental shelf to enable rivers to transport more terrestrial materials to the slope; and the situation reverses during the interglacials. The n-alkane indexes changes reveal more n-alkanes from contemporary vegetation during glacials as a result of the proximity of the core site to the source region, while the increases in ACL and C81/C27 ratio during glaclals indicate a change to more grassy vegetation. However, the highest values for CPI, ACL and the C81/C27 ratio all occurred during late MIS 3, and it was suggested that this period was characterized by a strong summer monsoon-dominated humid climate which resulted in a denser vegetation for the exposed continental shelf region.
